Electrons tunneling through the gate of an ultra-scaled transistor.
The continued down-scaling of transistors has enabled tremendous advances in consumer electronics. We are reaching the limits where individual transistors or on-off electron valves are only a few nanometers in diameters wide. At these atomic length scales the electrons no longer act like billiard balls but rather like waves. As a result, electrons can tunnel through forbidden device regions, causing additional conduction and heat generation paths. Sophisticated modeling engines that consider a quantum mechanical description of the electrons, an atomistic description of the material, and non-equilibrium electron distributions, are needed for device design and optimization.
The "OMEN_FET" tool on nanoHUB.org enables such device modeling, and allows for the visualization of the electron density in such ultra-scaled structures through 3D volume rendering.
The current density was computed with the OMEN_FET tool and visualized with the nanoVIZ tool on nanoHUB.org.

Dip and Dressing Bases Simplify Formulation and Production
Food product developers can now create new dressings and dips with better stability, cleaner labels and greater consumer appeal using Chef-Ready and SeasonRite bases from Advanced Food Systems. These bases simplify formulation and production by combining ingredients into easy-to-use pre-blended powders formulated to impart clean flavor, vibrant color and smooth, creamy texture. They can be easily customized with flavors, seasonings and spices. Clean label options include preservative-free, reduced sodium, reduced fat, allergen-free, and natural flavors to appeal to health-conscious consumers.
To create signature dips and dressings, developers can choose from AFS's extensive collection of flavors, including Balsamic, Ranch, Plum Chili Garlic, Artichoke, Bleu Cheese and Ginger Wasabi, or add their own flavors and seasonings to one of the mild flavor bases. Products can also be formulated to be shelf-stable.

Last weekend Panoramio reached half a million photos uploaded. Approximately 400.000 of them geolocated in the place they were taken.
We are very excited watching how the community of people using Panoramio is growing at a this huge speed. The increasing flow of photos is creating every day a more useful way to explore the World.
It is a difficult task to moderate all these photos for the small team of Panoramio, but people is helping us very much through the collaborative tools. Users can flag offensive or not descriptive photos, also they can suggest new locations to misplaced photos. People is collaborating so much that even moderating flags and suggestions is becoming a day-long task itself. Anyway, we don't complain, we are very grateful to all you.
We are still dealing with issues related with the enormous amount of people using Panoramio. We made some great advances and now the site is quite fast most of the day. The exception is between 22-24 hours (GMT +1) when American an European users are surfing at the same time. As I said before, this is not a complain, this are the kind of problems you love to have.
Once more, thanks! ¡gracias!

- What's Included
Maybe, until today, it didn't make sense for most of us to store things in places more secure than the drawers of our desks. But life has gotten more complicated, and for most, safekeeping is a way of life and business. MyCube is the first company to combine safekeeping with technology and style. The MyCube safe has been specifically designed to charge electronic devices (most laptops up to 17 inches, smartphones, tablets, etc.) while keeping them safe. Of course, it's also just the right size for jewelry, passports and valuable papers, all accomplished with great color and style!
MyCube is made of eighth-inch thick reinforced steel with a 4-digit code digital keypad for quick opening and one-button push locking. The digital lock triggers two tamper-proof steel bolts, which keep the door tightly closed. It has an internal charging outlet with a battery powered digital LED screen keypad and a manual over-ride. It is a manageable 40 pounds, and can be bolted securely to floors, cabinets or shelves.
The digital lock is battery powered, separate from the internal outlet, which is power via an external 3-prong plug. A manual key is also included to be able to open the safe if the batteries run out in the keypad.
The MyCube Safe is designed to discourage and deter theft and to create secure storage for your valuable papers and the things you treasure. No installation is foolproof, of course, but to increase security it is suggested securing MyCube to two strong surfaces via the built-in mounting holes and screws.
There are six colors to choose from: Black, Blue, Orange, Pink, Silver and White.

Thanksgiving and Brown Bread
I've been neglecting this blog but I swear it's for good reason. I just launched KNG Sommers Photography (my new and improved photography business) mailed out two weddings and two baby sessions, photographed two family sessions, (um, is two the magic number?) went to a beer canning for the Heavy Table and hung out with some cattle down in Cannon Falls, MN for Simple, Good and Tasty (I'll make sure to post a link when that article publishes) and all of that normal other day life stuff too. Sound like I have a problem saying no?
The other big news is that as of December 1st this blog will be moving to a new domain! I'm keeping it under wraps until then, but will go live on Tuesday with a month of fun culinary giveaways and much more frequent blog posts. Until then I'll keep you occupied with a delicious stuffing recipe and tempt you with the experimental purchase I made this week.
I was so looking forward to this holiday weekend. With very few obligations and nothing immediately on the chopping block Kyle and I spent all day on Wednesday doing nothing. Yesterday while I was working from home Kyle prepared "2nd Thanksgiving" which is a fun excuse to cook and drink two days in a row.
I don't care much for Turkey. It's fine I suppose, but I certainly don't obsess over it and Thanksgiving without turkey would be fine with me. What I really look forward to is the stuffing. And let me be clear, I really don't like most stuffing either. That mushy stuff that looks like baby food? Keep it away from me. I like southern cornbread and sausage stuffing. And no, my cornbread did not come in the form of dehydrated croutons (that is sacrilegious if you ask me). For my stuffing you make a good, hearty and savory cornbread. Mix it with onions, sausage, heavy cream and sherry and you have a little dish of heavy worth being thankful for.
It is also the best leftover because it is SO good for breakfast. Just fry an egg or two, put them on top of your reheated stuffing and voila, instant southern breakfast! Being a "stovetop" stuffing, you can really make it as a side dish any day of the week with the roasted bird being entirely optional.
Cornbread Stuffing From Time Life Foods of the World: American Cooking
- 8 T butter
- 1 1⁄2 c finely chopped onion
- 1 lb sausage meat
- 1⁄2 t salt
- freshly ground pepper
- 2 t fresh thyme leaves
- 1⁄4 c finely chopped parsley
- 1⁄4 c dry madiera or sherry
- 1⁄4 c heavy cream
Cornbread for stuffing
1 ½ C. yellow cornmeal
1 C. all-purpose flour
1 t. salt
1 T. baking powder
2 eggs
½ C. melted butter
1 ½ C. milk
Preheat the oven to 400º. Sift dry ingredients into a mixing bowl. Beat the eggs lightly, stir in the milk and add the melted butter. Pour into the bowl of dry ingredients and beat together for about a minute, or until smooth. Do not overbeat. Lightly butter an 8-by-12 inch shallow baking pan and pour in the batter. Bake in the center of the oven for about 30 minutes, or until the bread comes slightly away from the edge of the pan and is golden brown.
While your cornbread is baking:
Melt the butter in a large, heavy skillet, add the chopped onions and cook over moderate heat for 6 to 8 minutes, or until they color lightly. Scrape them in into a large mixing bowl. Add the sausage to the skillet, now set over medium heat, and break the meat up with a fork as it cools. When the meat is lightly browned, transfer it to a sieve set over a small bowl and let the fat drain through. Combine the drained sausage meat, cornbread crumbs, salt a few grindings of pepper, the thyme and parsley. With a large spoon, gently stir the ingredients together, then moisten with the sherry and cream. Taste for seasoning.
(The original recipes calls to brown the turkey liver in butter, then to chop and add it as well, but my mom always puts it in the gravy. I on the other hand usually end up with a Kosher Bird which doesn't include the innards)
Then there was dessert. We made a normal pumpkin pie, which is great and all. But then we all had to try this New England delicacy I found at Byerly's this week
Apparently brown bread was created when most people New England didn't have ovens and cooked everything in a fireplace. The bread is essentially steamed rather than baked. I found a recipe so you can try it at home here, or you can go to the baked beans section of your grocery store and keep your fingers crossed that they too carry brown bread.
Taste profile: Well, it reminded me of eating really bland gingersnap cookie dough. It's definitely sticky and was pretty challenging to slice. I followed the recommended serving methods of toasting and microwaving along with serving it in its' raw state and I followed the suggestion of putting cream cheese on it. In summary, I wouldn't buy it again for any reason, but I might be inclined to try making it as a novelty if I had a lot of spare molasses on hand for some reason.

|"Law Man"
|For a Western movie this was very boring and had very little going on. There is no real plot and only a couple of muddled and drama-free sub-plots. The movie is about some hit-man in a cell who is awaiting hanging for the killing of some cattleboys. The sheriff wants a peaceful hanging (!) without having to prove that he's as good a Sheriff as his father was. And a couple of other minor characters serve no purpose other than to complicate matters for petty reasons. There are a few silly fight scenes that remind of the A-Team with the wooden furniture falling apart very easily. And, as always, there are embarrassingly fake fights in which there is no penetration seen or any shown. Were there any R-rated movies in the 50's? But the most annoying thing about this movie is the songs but the 'singing narrator' who only ever uses the same tune but uses marginally different words each time. Ugh! If this is on TV on a Sunday afternoon miss it. Go out for a walk, even if it's raining.

Samsung smartphone and tablet users can now buy all their video apps, e-books and games using PayPal.
San Jose-based PayPal announced Wednesday that its mobile payments platform works across the Samsung ecosystem. PayPal is available on the Samsung Hub — the company's online entertainment center for music, TV shows, games, books and education apps — and the Samsung Apps store. Users just have to authenticate their PayPal account and they can downloading apps.
Samsung developers can also get paid for their work through PayPal.
"Instead of waiting several days for wire transfers, Samsung Apps developers can now get paid quickly and securely through PayPal, gaining access to 132 million PayPal customers around the world," PayPal wrote in a blog post.
Developers in any part of the world now have access to PayPal, as do consumers in Australia, Italy, France, Germany, Malaysia, Singapore, Spain and the U.K. But Samsung device owners in the U.S. will have to wait — PayPal won't be available here until the end of the year.
PayPal also works in the iOS app stores in some countries and in the Windows app store.
The Samsung rollout is the latest chapter in PayPal's evolution from its roots as an online payments provider to a larger mobile presence, and gives PayPal access to consumers of one of the fastest-growing smartphone brands. South Korea-based Samsung is one of the biggest rivals for Apple in the mobile device market and is hugely popular overseas where Apple has stumbled. Samsung holds on to the title of Asia's top brand out of 1,000 competitors for a second year in a row, beating Apple, according to Asia's Top 1000 Brands report, published in July by research firms Campaign Asia-Pacific and Nielsen.
Samsung's first-quarter profit reached a record high of $6.5 billion in the first quarter of this year. Sales were up 17 percent during the same three-month period after the holidays, which for most consumer electronics companies is the slowest time of the year.
Further strengthening PayPal's global presence is eBay's $800 million purchase of payment gateway Braintree last month. The acquisition wipes out one of PayPal strongest rivals on smartphones and tablets. And the company recently released a new version of its application for both iPhone and Android devices, one that it hopes will secure the company's footprint in the mobile e-commerce market.
PayPal's mobile payments increased from $141 million in 2009 to $14 billion in 2012. The company is projecting to reach $20 billion this year.

|Test Code
|Test Copy Genes
|CPT Code Copy CPT Codes
Pricing Comments
This test is also offered via our exome backbone with CNV detection (click here). The exome-based test may be higher priced, but permits reflex to the entire exome or to any other set of clinically relevant genes.
Targeted Testing
For ordering sequencing of targeted known variants, please proceed to our Targeted Variants landing page.
Turnaround Time
The great majority of tests are completed within 20 days.
Clinical Sensitivity
This test is predicted to detect disease mutations in at least 95% of individuals with EDS IV (Pepin & Byers. GeneReviews. 2011).
About 2% of individuals with EDS IV have large deletions involving single or multiple exons. So far, less than 10 large deletions have been reported in COL3A1 (Meienberg et al. 2010; Human Gene Mutation Database).
Clinical Features
Ehlers-Danlos syndrome type IV (EDS IV or Vascular EDS, OMIM# 130050) is characterized by thin, translucent skin; easy bruising; characteristic facial appearance, and arterial, intestinal, and/or uterine fragility (Pepin & Byers. GeneReviews. 2011). Vascular dissection or rupture, gastrointestinal perforation, or organ rupture are the presenting signs in the majority of adults identified to have EDS IV. In childhood, inguinal hernia, pneumothorax, and recurrent joint subluxation or dislocation can occur. Pregnancy for women with EDS type IV has as much as a 12% risk for death from peripartum arterial rupture or uterine rupture.
EDS IV is inherited in an autosomal dominant manner and is caused by mutations in the COL3A1 gene. About half of affected individuals have inherited the mutation from an affected parent, and the other half have a de novo COL3A1 mutation. COL3A1 encodes the proα1(III) chain of type III procollagen, a major structural component of skin, blood vessels, and hollow organs. The type III procollagen molecule is a homotrimer; COL3A1 mutations typically result in a structural alteration of type III collagen that leads to intracellular storage and impaired secretion of collagen chains. The majority of identified mutations result in substitution of other amino acids for glycine residues in the Gly-X-Y triplets of the triple helical domain.
In one recent study, 410 unique COL3A1 mutations were identified in 572 out of 630 clinical diagnosed EDS vascular type families. Among the families with COL3A1 mutations, ~62% (356/572) carried a mutation affecting glycine in the Gly-X-Y triple helix domain, ~29% (164/542) had splicing site mutation (donor site: 144/164, acceptor site 20/164), ~ 7% (42/572) had small deletion/insertions and 10 families had large deletions detected by MLPA method (Pepin et al. 2014).
Testing Strategy
For this Next Generation Sequencing (NGS) test, sequencing is accomplished by capturing specific regions with an optimized solution-based hybridization kit, followed by massively parallel sequencing of the captured DNA fragments. Additional Sanger sequencing is performed for regions not captured or with insufficient number of sequence reads.
For Sanger sequencing, polymerase chain reaction (PCR) is used to amplify targeted regions. After purification of the PCR products, cycle sequencing is carried out using the ABI Big Dye Terminator v.3.0 kit. PCR products are resolved by electrophoresis on an ABI 3730xl capillary sequencer. In nearly all cases, cycle sequencing is performed separately in both the forward and reverse directions.
Copy number variants (CNVs) are also detected from NGS data. We utilize a CNV calling algorithm that compares mean read depth and distribution for each target in the test sample against multiple matched controls. Neighboring target read depth and distribution and zygosity of any variants within each target region are used to reinforce CNV calls. All CNVs are confirmed using another technology such as aCGH, MLPA, or PCR before they are reported.
This test provides full coverage of all coding exons of the COL3A1 gene, plus ~10 bases of flanking noncoding DNA. We define full coverage as >20X NGS reads or Sanger sequencing.
Indications for Test
Candidates for this test are patients with clinical and/or biochemical features consistent with EDS IV, and family members of patients who have known COL3A1 mutations.

Sequencing and CNV Detection via NextGen Sequencing using PG-Select Capture Probes
Test Procedure
NextGen Sequencing
We use a combination of Next Generation Sequencing (NGS) and Sanger sequencing technologies to cover the full coding regions of the listed genes plus ~10 bases of non-coding DNA flanking each exon. As required, genomic DNA is extracted from the patient specimen. For NGS, patient DNA corresponding to these regions is captured using an optimized set of DNA hybridization probes. Captured DNA is sequenced using Illumina's Reversible Dye Terminator (RDT) platform (Illumina, San Diego, CA, USA). Regions with insufficient coverage by NGS are covered by Sanger sequencing.
For Sanger sequencing, Polymerase Chain Reaction (PCR) is used to amplify targeted regions. After purification of the PCR products, cycle sequencing is carried out using the ABI Big Dye Terminator v.3.0 kit. PCR products are resolved by electrophoresis on an ABI 3730xl capillary sequencer. In nearly all cases, cycle sequencing is performed separately in both the forward and reverse directions.
Patient DNA sequence is aligned to the genomic reference sequence for the indicated gene region(s). All differences from the reference sequences (sequence variants) are assigned to one of five interpretation categories, listed below, per ACMG Guidelines (Richards et al. 2015).
(1) Pathogenic Variants
(2) Likely Pathogenic Variants
(3) Variants of Uncertain Significance
(4) Likely Benign Variants
(5) Benign Variants
Human Genome Variation Society (HGVS) recommendations are used to describe sequence variants (http://www.hgvs.org). Rare variants and undocumented variants are nearly always classified as likely benign if there is no indication that they alter protein sequence or disrupt splicing.
Deletion and Duplication Testing via NGS
Analytical Validity
NextGen Sequencing
As of March 2016, 6.36 Mb of sequence (83 genes, 1557 exons) generated in our lab was compared between Sanger and NextGen methodologies. We detected no differences between the two methods. The comparison involved 6400 total sequence variants (differences from the reference sequences). Of these, 6144 were nucleotide substitutions and 256 were insertions or deletions. About 65% of the variants were heterozygous and 35% homozygous. The insertions and deletions ranged in length from 1 to over 100 nucleotides.
In silico validation of insertions and deletions in 20 replicates of 5 genes was also performed. The validation included insertions and deletions of lengths between 1 and 100 nucleotides. Insertions tested in silico: 2200 between 1 and 5 nucleotides, 625 between 6 and 10 nucleotides, 29 between 11 and 20 nucleotides, 25 between 21 and 49 nucleotides, and 23 at or greater than 50 nucleotides, with the largest at 98 nucleotides. All insertions were detected. Deletions tested in silico: 1813 between 1 and 5 nucleotides, 97 between 6 and 10 nucleotides, 32 between 11 and 20 nucleotides, 20 between 21 and 49 nucleotides, and 39 at or greater than 50 nucleotides, with the largest at 96 nucleotides. All deletions less than 50 nucleotides in length were detected, 13 greater than 50 nucleotides in length were missed. Our standard NextGen sequence variant calling algorithms are generally not capable of detecting insertions (duplications) or heterozygous deletions greater than 100 nucleotides. Large homozygous deletions appear to be detectable.
Analytical Limitations
NextGen Sequencing
Interpretation of the test results is limited by the information that is currently available. Better interpretation should be possible in the future as more data and knowledge about human genetics and this specific disorder are accumulated.
When Sanger sequencing does not reveal any difference from the reference sequence, or when a sequence variant is homozygous, we cannot be certain that we were able to detect both patient alleles. Occasionally, a patient may carry an allele which does not amplify, due to a large deletion or insertion. In these cases, the report will contain no information about the second allele. Our Sanger and NGS Sequencing tests are generally not capable of detecting Copy Number Variants (CNVs).
We sequence all coding exons for each given transcript, plus ~10 bp of flanking non-coding DNA for each exon. Test reports contain no information about other portions of the gene, such as regulatory domains, deep intronic regions or any currently uncharacterized alternative exons.
In most cases, we are unable to determine the phase of sequence variants. In particular, when we find two likely causative mutations for recessive disorders, we cannot be certain that the mutations are on different alleles.
Our ability to detect minor sequence variants due to somatic mosaicism is limited. Sequence variants that are present in less than 50% of the patient's nucleated cells may not be detected.
Runs of mononucleotide repeats (eg (A)n or (T)n) with n >8 in the reference sequence are generally not analyzed because of strand slippage during PCR.
Unless otherwise indicated, DNA sequence data is obtained from a specific cell-type (usually leukocytes from whole blood). Test reports contain no information about the DNA sequence in other cell-types.
We cannot be certain that the reference sequences are correct.
Rare, low probability interpretations of sequencing results, such as for example the occurrence of de novo mutations in recessive disorders, are generally not included in the reports.
We have confidence in our ability to track a specimen once it has been received by PreventionGenetics. However, we take no responsibility for any specimen labeling errors that occur before the sample arrives at PreventionGenetics.

State House - First floor
In Room 143 on the first floor (northeast corridor) is the Royal Charter Museum. The Charter Museum contains many priceless documents and artifacts that represent Rhode Island's important place in history. The centerpiece of the Museum - the Royal Charter of 1663 granted by King Charles II of England, resides in a custom steel vault. The Charter guaranteed Rhode Island settlers freedom of religion and the freedom to govern their own colony. The Charter is in the care of the Secretary of State, who has been the keeper of records since colonial times. For many years this document had been attached to a piece of cardboard at the back of the vault. But because it is written on parchment (sheep or goat skin), it needs to expand and contract, just like your own skin. In 1996, Conservators removed the Charter from the cardboard, and devised a new storage system. If you look closely, you can see that the Charter is suspended on threads, which now allow the parchment to expand and contract.
The Gettysburg Gun is found in the foyer of the main public entrance to the State House. Behind it, you will see Civil War flags. The cannon is a special attraction because it has an unusual history.
The cannon was last fired during the 1863 Civil War battle at Gettysburg, Pennsylvania. It still has a cannonball wedged in its muzzle. While soldiers of Rhode Island's Battery B, First Light Artillery were loading a shot, the cannon muzzle was hit by a Confederate shell. The dent from the explosion caused the muzzle to become deformed, and when the surviving gunners tried to load a new shot, it became jammed in the muzzle. The cannon was on exhibit in Washington, DC, until 1874, when it was returned to Rhode Island.
On August 24, 1962 (almost one hundred years after it became disabled) it was discovered that two and a half pounds of black gunpowder were still in the cannon. Gunpowder becomes more sensitive as it ages and is highly dangerous. People working at the State House were worried when they learned it could explode.
On August 25, 1962 the Rhode Island National Guard removed the cannon from the State House to the National Guard Maintenence shop in Smithfield. Two days later, they successfully removed the black powder, and the cannon was safely returned to the State House. From the outside the Gettysburg Gun still looks exactly as it did at the end of the battle on July 3, 1863. Can you find the drill hole?
The rotunda is made of Georgia marble and its interior is decorated with artwork and gold leaf. The marble was chosen because of its beautiful white tones which take on a golden glow as it ages. A rotunda is a large round room that often has a domed ceiling. In the middle of our rotunda, on the center of the floor, you will see a beautiful brass replica of the State Seal. It has a golden appearance and is inlaid in the marble floor. It is encircled with a velvet rope to keep it protected. An anchor is depicted in the center of the seal. The anchor is a symbol of hope. Above the anchor is the word "Hope", our state´s motto. One reason why we use this motto is because the word is found in a famous quote from our state´s founder, Roger Williams, who told the early settlers to have "Hope in the Divine". The anchor also reminds us of water. As you know, Rhode Island's nickname is the "Ocean State", because Rhode Island has over 400 miles of shoreline even though our state is only 48 miles long from north to south and 37 miles wide from east to west. A garland of leaves surrounds the shield which bears the anchor. Written around the seal are the words: "Seal of the State of Rhode Island and Providence Plantations 1636." Don't you think it's interesting that ours is the smallest state but has the longest name?
The Liberty Bell is found in the foyer (entrance hall) of the south entrance of the State House (the side which faces downtown Providence). It was donated to the people of Rhode Island by the United States Treasury Department in 1950 while Harry S. Truman was President. This bell is a reproduction of the original Liberty Bell, which means it looks just like the original bell in Independence Hall in Philadelphia, Pennsylvania. The bell is about 3-1/2 feet tall and its diameter at its widest part is about 3-1/2 feet. The Pennsylvania Liberty Bell was last rung in 1835 when it cracked at the funeral of Chief Justice John Marshall. If you look closely, you will see that our bell also has a simulated crack just like the original Liberty Bell. The words on this famous bell read:
PROCLAIM LIBERTY THROUGHOUT ALL THE LAND UNTO ALL THE INHABITANTS THEREOF BY ORDER OF THE ASSEMBLY OF THE PROVINCE OF PENSYLVANIA FOR THE STATE HOUSE IN PENSYLVANIA PASS AND STOW PHILAD a MDCCLIII

I'd like to motivate OCaml's object-oriented features (the "O" in "OCaml") by showing an encoding of (first-order) Haskell type classes. This will require making use of almost everything in OCaml's object buffet: class types, virtual classes, inheritance of class types and of classes, double dispatch and coercion.
Haskell could be said to have the best type system among all languages in wide use at the moment, striking a delicate balance between power and practicality without compromising purity (neither conceptual nor functional). In the words of Oleg Kiselyov, it sports "attractive types". A great feature is the presence of type-indexed values via the type-class mechanism. In a nutshell, type-indexed values are functions from types to values. A classic example is overloaded operators, where for instance the same symbol
+ denotes addition over the integers, floating-point and rational numbers, depending on the type of its parameters. Haskell provides "type magic" to automatically infer the intended function (the value) based on the types of the arguments to which it is applied, achieving a form of type-safe "ad-hoc" polymorphism.
The ML family of languages doesn't have the machinery to attain such expressive power. There are, however, a number of ways to encode type-indexed families with an explicit parameter encoding the selector type. The oldest, and most complicated technique is that of Danvy (see also this complete example) which is not really equivalent to Haskell's type classes but a sophisticated application of phantom types. Another technique is using an explicit dictionary (Yaron Minsky has a worked example) from which to select the appropriate operation. Normally these dictionaries are records; the labels provide type-safe instantiation of the generic value family. The problem with records is that they are not extensible, so it is not immediate how to encode the equivalent of inheritance of type classes. OCaml's object-oriented sublanguage is especially well-suited for the task, allowing for a natural encoding that shows that the "class" in Haskell's "type classes" is more object-oriented than it seems at first sight.
I'll start with a bit of Haskell's standard prelude, as shown in the Report in a nice graph. I'll focus on the two most common nontrivial classes,
Eq and
Ord. The first is defined as:
class Eq a where (==), (/=) :: a -> a -> Bool x /= y = not (x == y) x == y = not (x /= y)
I encode a Haskell type class in OCaml with… (surprise!) a class type and associated functions:
class type ['a] eq = object method equal : 'a -> 'a -> bool method not_equal : 'a -> 'a -> bool end
Since the type class has a type parameter a, my class type also has a type parameter
'a. Each member of the type class corresponds to a (named) method and to a regular function taking the class type as a dictionary parameter:
let (===) x y (eq : 'a #eq) = eq#equal x y and (<=>) x y (eq : 'a #eq) = eq#not_equal x y
(I've opted to not shadow the regular operators in
Pervasives). The weird order of the parameters (you'd expect the dictionary to come first) is such that I can write:
if x === y $ eq_int then …
($) is the application operator. Haskell provides default implementations for both members; as the Report notes:
This declaration gives default method declarations for both /= and ==, each being defined in terms of the other. If an instance declaration for Eq defines neither == nor /=, then both will loop.
I find that unsettling, so I'll just define one via a virtual class (not class type):
class virtual ['a] eq_base = object (self) method virtual equal : 'a -> 'a -> bool method not_equal x y = not (self#equal x y) end
In this case,
equal is left virtual. It is important that the class be left virtual even if
equal is defined, so that it cannot be instantiated. This means that it cannot be coerced to the class type
eq, since it is illegal to shadow virtual members that were declared non-virtual. Now come the instances of the type class. In Haskell, a very simple instance is that for
unit which is built-in (via
deriving) but could be declared as:
instance Eq () where () == () = true
To encode instances, I use an immediate object bound to an identifier:
let eq_unit : unit eq = object inherit [unit] eq_base method equal () () = true method not_equal () () = false end
Note the coercion to the corresponding monomorphic instance of the class type. I inherit from the default implementation in the class base, even if in this case I explicitly implement all methods for efficiency. The same encoding works for booleans too:
let eq_bool : bool eq = object inherit [bool] eq_base method equal = (==) method not_equal = (!=) end
OCaml has built-in ad-hoc polymorphic comparisons that I could use directly:
class ['a] eq_poly : ['a] eq = object inherit ['a] eq_base method equal = Pervasives.(=) method not_equal = Pervasives.(<>) end
With that I can have type classes for the primitive types:
let eq_int = (new eq_poly :> int eq) and eq_float = (new eq_poly :> float eq) and eq_char = (new eq_poly :> char eq) and eq_string = (new eq_poly :> string eq)
Here I instantiate objects of the
eq_poly class coerced to the correct monomorphic instance of
eq (recall that in OCaml coercion is always explicit). The type class instance for pairs requires type classes for each of its components. In Haskell, we'd have:
instance (Eq a, Eq b) => Eq ((,) a b) where …
(not really, but let me gloss over that). Encoding that in OCaml also requires a witness for each type parameter as explicit arguments to the constructor:
let eq_pair (l : 'a eq) (r : 'b eq) : ('a * 'b) eq = object (self) inherit ['a * 'b] eq_base method equal (p, q) (p', q') = l#equal p p' && r#equal q q' end
An inefficiency of this encoding is that it creates a new object with every invocation of the witness function. For instance, in general
eq_pair eq_unit eq_bool != eq_pair eq_unit eq_bool and so on for every witness. The same is needed to encode an equality witness for
option types:
let eq_option (o : 'a eq) : 'a option eq = object inherit ['a option] eq_base method equal x y = match x, y with None , None -> true | Some x, Some y -> o#equal x y | _ -> false end
And for
let eq_list (o : 'a eq) : 'a list eq = object inherit ['a list] eq_base method equal = let rec equal x y = match x, y with | [], [] -> true | _ , [] | [], _ -> false | x :: xs, y :: ys when o#equal x y -> equal xs ys | _ -> false in equal end
(I use explicit closed recursion for efficiency). In all these cases, I encoded a derived instance via an explicit witness passed as a parameter. Derived type classes require genuine inheritance of class types, as seen in the encoding of Haskell's
Ord type class:
class (Eq a) => Ord a where compare :: a -> a -> Ordering (<), (<=), (>), (>=) :: a -> a -> Bool max, min :: a -> a -> a
(I omit showing the default implementations). I use the SML
ordering type for fidelity:
type ordering = LT | EQ | GT let of_comparison c = if c < 0 then LT else if c > 0 then GT else EQ and to_comparison = function LT -> -1 | EQ -> 0 | GT -> -1
The class type encoding the
Ord type class is:
class type ['a] ord = object inherit ['a] eq method compare : 'a -> 'a -> ordering method less_equal : 'a -> 'a -> bool method less_than : 'a -> 'a -> bool method greater_equal : 'a -> 'a -> bool method greater_than : 'a -> 'a -> bool method max : 'a -> 'a -> 'a method min : 'a -> 'a -> 'a end
Again, operators take an explicit witness as a dictionary:
let (<==) x y (ord : 'a #ord) = ord#less_equal x y and (<<<) x y (ord : 'a #ord) = ord#less_than x y and (>==) x y (ord : 'a #ord) = ord#greater_equal x y and (>>>) x y (ord : 'a #ord) = ord#greater_than x y
And I provide a virtual class with default implementations:
class virtual ['a] ord_base = object (self) inherit ['a] eq_base method virtual compare : 'a -> 'a -> ordering method equal x y = match self#compare x y with EQ -> true | _ -> false method less_equal x y = match self#compare x y with GT -> false | _ -> true method less_than x y = match self#compare x y with LT -> true | _ -> false method greater_equal x y = match self#compare x y with LT -> false | _ -> true method greater_than x y = match self#compare x y with GT -> true | _ -> false method max x y = match self#compare x y with LT -> y | _ -> x method min x y = match self#compare x y with GT -> y | _ -> x end
Note how the class type inheritance
ord :> eq translates into class inheritance
ord_base :> eq_base. The instances for
unit and
bool use inheritance and selective overriding for efficiency:
let ord_unit : unit ord = object inherit [unit] ord_base method equal = eq_unit#equal method not_equal = eq_unit#not_equal method compare () () = EQ method max () () = () method min () () = () end let ord_bool : bool ord = object inherit [bool] ord_base method equal = eq_bool#equal method not_equal = eq_bool#not_equal method compare b b' = match b, b' with | false, true -> LT | true, false -> GT | _ -> EQ method max = (||) method min = (&&) end
In order to profit from the efficient implementation of
equal and
not_equal I explicitly delegate on the methods in the corresponding
eq instances. Now as before I can use the ad-hoc polymorphic operators in
Pervasives to speed writing the type classes for atomic types:
class ['a] ord_poly : ['a] ord = object inherit ['a] ord_base method compare x y = of_comparison (Pervasives.compare x y) method less_equal = Pervasives.(<=) method less_than = Pervasives.(< ) method greater_equal = Pervasives.(>=) method greater_than = Pervasives.(> ) method max = Pervasives.max method min = Pervasives.min end let ord_int = (new ord_poly :> int ord) and ord_float = (new ord_poly :> float ord) and ord_char = (new ord_poly :> char ord) and ord_string = (new ord_poly :> string ord)
(Note the use of the injection into
ordering). The case for pairs requires appropriate witnesses as before:
let ord_pair (l : 'a ord) (r : 'b ord) : ('a * 'b) ord = object inherit ['a * 'b] ord_base method equal = (eq_pair (l :> 'a eq) (r :> 'b eq))#equal method compare (p, q) (p', q') = match l#compare p p' with EQ -> r#compare q q' | c -> c end
In this case, delegating
equal requires passing the witnesses to
eq_pair explicitly coerced to the
eq class type. Finally, the classes for
options and
lists are straightforward applications of the encoding:
let ord_option (o : 'a ord) : 'a option ord = object inherit ['a option] ord_base method equal = (eq_option (o :> 'a eq))#equal method compare x y = match x with None -> (match y with None -> EQ | Some _ -> LT) | Some x -> (match y with None -> GT | Some y -> o#compare x y) end let ord_list (o : 'a ord) : 'a list ord = object inherit ['a list] ord_base method equal = (eq_list (o :> 'a eq))#equal method compare = let rec compare x y = match x, y with | [], [] -> EQ | _ , [] -> GT | [], _ -> LT | x :: xs, y :: ys -> match o#compare x y with | EQ -> compare xs ys | c -> c in compare end
As it is clear, the encoding shows a direct correspondence between Haskell type classes and OCaml's classes and objects:
- type classes into class types with top-level functions dispatching on a witness object of that class type
- derived type classes into inheriting class types
- default implementations into virtual classes
- instances into objects inheriting from the default virtual class
- derived instances into objects having witnesses of the appropriate class type
In every case, the witness objects are used purely as closed vtables without state. It would be interesting to investigate which use cases would open using row polymorphism or data members. Also, note that there is no need to abstract over the object types, as each witness carries with it the intended implementation in a type-safe manner.
This technique is analogous to the one using functors to encode type classes,
but then why have both in the same language?, in the words of Jacques Garrigue. One reason is that functors are not first-class values in OCaml but objects are, which makes using them as type witnesses much more lightweight. On the other hand, one limitation that functors don't have is that this encoding is limited to first-order type classes. In other words, it is not clear what would be required to implement Haskell type classes like:
instance (Monad m) => Functor m where fmap f x = bind x (return . f)
where m is a type constructor with sort
* → * using the encoding presented here, whereas it is straightforward to concoct a (ML) functor:
module MonadFunctor (M : MONAD) : FUNCTOR = struct type 'a t = 'a M.t let fmap f x = M.bind x (fun v -> M.return (f v)) end
Another limitation is the need to pass a witness object to the type-indexed functions. One would ideally want to write something like:
let (===) (x : eq) = x#equal
where the value is its own witness, but obviously this would require that every value be wrapped into an object, requiring, for instance, code like the following:
if (new eq_int 5) === (new eq_int x) then …
Moreover, in order to actually operate on the wrapped values, the classes would need an explicit accessor. OCaml supports double dispatch making possible forcing the types of x and y to be equal:
class type ['a] eq = object ('self) method value : 'a method equal : 'self -> bool method not_equal : 'self -> bool end class eq_int x : [int] eq = object (self : 'self) method value = x method equal (that : 'self) = self#value == that#value method not_equal (that : 'self) = self#value != that#value end
Canonicalizing the witnesses for finite types like
bool is very tedious:
let eq_bool : bool -> bool eq = let _t : bool eq = object method value = true method equal that = that#value method not_equal that = not (that#value) end and _f : bool eq = object method value = false method equal that = not (that#value) method not_equal that = that#value end in fun b -> if b then _t else _f
(essentially, a Church-encoded boolean). More importantly, this encoding is much more dynamic, making it rather remote with respect to the original, fully static Haskell semantics (this, incidentally, is a definite advantage of the functorial encoding).
In closing, it would be interesting to see how far this technique can be carried, especially to implement a numeric tower analogous to Haskell's, or maybe a better type class hierarchy to encode would be that of the Numeric Prelude. Another necessary avenue of investigation is measuring the abstraction penalty incurred by this encoding. In any case, I believe this is a neat showcase of the often-forgotten object-oriented features in OCaml.

ECHL: Lynx Has Not Folded
WJBF-TV Channel 6 in Augusta is reporting that the ECHL announced late Wednesday afternoon that the Augusta Lynx will remain a member of the league. From that JFBF report:
A release from ECHL Senior Vice President of Communications Jack Carnefix said "In response to published reports about the future of the Augusta Membership, the ECHL hereby announces that contrary to those reports the Augusta Lynx continue as a member in the ECHL. Any rumors to the contrary are simply not true. Augusta plays at Gwinnett on Thursday at 7:05 p.m. and hosts Charlotte on Saturday at 7 p.m. before traveling to Charlotte on Sunday at 4 p.m.â€
The announcement came in response to a report on the Charlotte Observer newspaper web site Wednesday that said the Charlotte Checkers, as well as other ECHL teams, were adjusting their schedule to account for the Lynx disbanding. The report went on to say that the ECHL Board of Governors would meet to decide Augusta's fate on Wednesday. The ECHL's release came confirming the Lynx membership in the league came after that meeting.
By early Wednesday afternoon, the report had been removed from the Observer's web site.

Ellis L. Brooks (1848-1920) was a trombonist, composer and popular bandleader with strong ties to West Michigan. Brooks directed famous bands in New York and Chicago during the late nineteenth century, and was ranked among contemporaries like Frederick Neil Innes, Patrick Sarsfield Gilmore and John Philip Sousa, both in terms of popularity and critical acclaim.
Brooks continued to maintain extremely popular bands across the country through the nineteen-teens, and employed many prominent West Michigan musicians, including Chester Z. Bronson, William S. Bronson, George Balcom and John Vleiken (of Kalamazoo), Frank Holton and Gardell Simons (both world-renowned trombonists from Allegan), and countless others.
Born in Massachusetts about 1848, Ellis Brooks spent his childhood with his family in Dunstable, Massachusetts. By 1861, young Brooks was playing trombone in the Dunstable Cornet Band. Brooks' father built the bandwagon for them.
Brooks toured for several years with various stage productions and minstrel companies, including Howard, Langrishe & Carle's "Black Crook" Company; Sweatnam, Billy Rice & Barney Fagan's Minstrels; the French Grenadier Military Band; and William Foote's Millennial Minstrels. Brooks later assumed leadership of the New York Concert Band, which is said to have rivaled the great bands of Innes, Gilmore and Sousa.
Brooks' band won great acclaim when it was introduced at the Minneapolis Industrial Exposition in 1887. During the wintertime months of the late 1880s and early 1890s, Brooks played at several of the large resorts along the New England coastline, and at least eight consecutive seasons at the historic Ponce de León, Alcazar and Cordova hotels in St. Augustine, Florida. Band members at this time included Frank Holton, Herbert L. Clarke, and Kalamazoo bandsman Chester Z. Bronson, all of whom later joined John Philip Sousa's New Marine Band in 1892. When Brooks appeared at the 1893 Pittsburgh Exposition, the star soloist with his band was Matilda Sissieretta Joyner Jones, the internationally famous African American singer known as "Black Patti."
In 1893, Brooks succeeded A. F. Weidon as leader of the famous Second Regiment Band of the Illinois Volunteer Infantry in Chicago, where he would continue to receive great acclaim. A crowd of 25,000 was on hand at the Indiana State Fair in September 1894 to witness a 140 piece massed band spectacular featuring Brooks' Second Regiment Band along with bands from Terre Haute, Cincinnati, and Indianapolis.
In December 1895, Brooks' Second Regiment Band could be heard in concert at Chicago's finest theaters; the Chicago Opera House, the Columbia Theater, Central Music Hall, the Masonic Temple, and the Auditorium. In January, the band performed afternoon and evening concerts at the Chicago Cycle Show for the thousands who attended. The following May, the band was giving concerts every afternoon, plus Saturday and Sunday matinees, at Chicago's Ferris Wheel Park on North Clark Street.
In September, Brooks' Second Regiment Band joined more than 1,000 supporters in serenading Republican presidential candidate William McKinley during part of his "front-porch" campaign in Canton, Ohio. (Brooks' "Chicago Post March" was said to have been one of President McKinley's favorites.) To commemorate the occasion, Brooks penned "The Voice of the Buckeye" for McKinley's 1896 campaign, dedicating the piece "in fond remembrance of the AEolian Silver Cornet Band of the 94th Regiment, O.V.I." Brooks directed the Chicago Second Regiment Band until May 1898.

The following year, Brooks was in Portland, Oregon, conducting the 25 member Third Regiment Band of the Oregon National Guard. In February 1900, Brooks led a series of benefit performances carried out over four consecutive evenings that featured Brooks' composition, "Victories of Old Glory on Land and Sea," accompanied by stereopticon slides "depicting the life of the soldier and sailor."
In the fall of 1900, Brooks moved to Grand Rapids, Michigan, where he was enlisted to direct the newly formed 40-member Furniture City Band and to head the music publishing division of the J.W. York Band Instrument Company. Brooks met with great success in Grand Rapids, and his performances were typically well attended. During the winter months, Brooks led an annual series of concerts at the Powers Opera House, where he continued to wow audiences with his multimedia epic "Victories of Old Glory in Peace and War" and other favorites. Summertime brought performances at John Ball Park and other summer resort work.
Shortly before John Philip Sousa's May 1901 concert in Grand Rapids, Brooks received word that Sousa intended to perform Brooks' "Forget Me Not Waltz" during his show. Perhaps to smooth the tension over a recruiting dispute a decade earlier (Brooks was upset that Sousa had apparently recruiting members of his band), Sousa invited Brooks to direct the popular number during his performance. Brooks accepted. Sousa's Band would also make a recording of Brooks' "Lagrimosa" soon after.
After several seasons with the Furniture City Band, Brooks left Grand Rapids in 1905 and moved back to Chicago to become a manager for Lyon & Healy, a prominent instrument manufacturing and music publishing firm. Unfortunately, Brooks suffered an apparent stroke during summer of 1905, and a second in October, which forced him to resign. Chicago musicians staged a benefit concert for Brooks in November, which featured several famous guest conductors, including Alfred Frederick Weldon, a long-time Chicago band director and composer; Frederick Neil Innes, a former member of Gilmore's band and one of the most famous bandleaders of his day; Carl Bunge, instructor at the Chicago Conservatory; Jacob F. Hostrawser, director of Chicago's famous Pullman Band; A. Fischer, and Charles E. Brinley. A commemorative march, "Remembrance," was penned for the occasion.
By 1909, Brooks was back on his feet, leading band concerts in Chicago during the summer months and touring the Southwest during winter. In November 1911, Brooks led his 40 piece military band at the opening of the Second Annual Expositon of the Texas Cotton Palace in Waco, Texas. For two straight weeks, Brooks' band was the chief entertainment and furnished two concerts each day for the estimated 200,000 in attendance.
In addition to his work as a bandleader and orchestra director, Ellis Brooks was a prolific arranger and composer of popular music, marches and semi-classical pieces. He even made a brief foray into ragtime. At one point, Brooks claimed to own the largest collection of music in the country—some 11,500 pieces—spanning more than a century.
The sound of Brooks bands survives today on several recordings from his era, including renditions by Sousa's Band, the New York Military Band, and Vessella's Italian Band. A few of Brooks' compositions also survive as piano rolls, cut during the early years of the twentieth century. Indeed many of Brooks' works are being performed by brass and marching bands to this day.

During the 1912 fall and winter season, Brooks was in Hamilton, New York, directing the Hamilton Military Band. By 1915, Brooks was leading his famous Chicago Band on annual summer tours with Lincoln Chautauqua, performing from Chicago to New Orleans, and all points in between. Brooks was featured as a guest conductor during a February 1915 performance by the Kalamazoo Symphony Orchestra, and his compositions were performed many times during that organization's formative years. Brooks' band also performed for twenty consecutive seasons at the prestigious annual Chicago Auto Show.
In May 1918, Brooks moved to Quincy, Illinois, where he became director of the Illinois State Band. Brooks passed away on 10 November 1920 following a brief illness. He was 72.

A Rare Scare Over Linux Security
Dec 29, 2011 5:00 AM PT
This story was originally published on Sept. 12, 2011, and is brought to you today as part of our Best of ECT News series.
Security scares are so commonplace in the tech industry today that it's virtually impossible to keep track of them all. Security scares in the Linux world, however, are still rare enough as to cause at least a small collective gasp of consternation.
That, indeed, is just what happened recently when it was discovered that the Kernel.org site had been breached last month.
"Earlier this month, a number of servers in the kernel.org infrastructure were compromised," read the note that was later posted on Kernel.org. "We discovered this August 28th. While we currently believe that the source code repositories were unaffected, we are in the process of verifying this and taking steps to enhance security across the kernel.org infrastructure."
It's since become pretty clear that the site's source code repositories remained intact, thanks largely to Linus Torvalds' Git distributed revision control system. Nevertheless, Torvalds himself last week temporarily moved Linux development to GitHub, and Linux fans around the globe are still shaking off the slight chill that resulted from the scare.
Not a Huge Deal
"Seriously people, this is big," wrote Mensa Babe on one of several Slashdot threads on the topic. "I really mean totally freaking big. Thanks to the open source nature of the kernel it is trivial to add a rootkit and make a new tarball. If the attackers were worth their salt then they should do exactly that."
On the other hand, "this security breach is not that big a deal," countered bzipitidoo. "Yes, it is embarrassing for kernel.org, but the damage is not that great. Sure, we'd all like to prevent security breaches from ever happening in the first place, but I have always thought detection and recovery is more important than prevention. Kernel.org has that covered in spades."
Indeed, according to another Slashdot post, the kernel attackers apparently didn't even really "know what they had."
Whatever the case, however, discussion of the event has extended to blogs and forums around the globe; Linux Girl's Quick Quotes Quill has never been so tired.
Not the End of the Linux World
"Cause for concern? Yes, but there's no reason to believe that kernel sources were compromised; such a change would be easily detected with diff," Hyperlogos blogger Martin Espinoza asserted, for example.
"I'd sure like someone to show me a 100 percent secure, internet-connected computer...," Espinoza added.
Similarly, "of course this is a serious concern but it's not the end of Linux by any means," agreed blogger Robert Pogson.
"I expect procedures on the servers will be tightened up to prevent/detect a recurrence," Pogson added. "Sometimes it takes a failure to provoke positive changes."
Meanwhile, "the ability of Linus to switch to GitHub running software that he wrote shows the tremendous adaptability of FLOSS," Pogson said.
Improving Confidence
Barbara Hudson, a blogger on Slashdot who goes by "Tom" on the site, took a similar view.
"A developer's remote machine co-located on the same network was compromised, their password sniffed, and used to do some monkey business on the kernel servers," Hudson told Linux Girl. "In the end, it looks like no permanent damage was done, and that the existing people, procedures and infrastructure are robust enough to recover cleanly."
In fact, "this should improve, not reduce, confidence in the Linux development process," Hudson opined.
Balancing Act
While some are "using the occasion to go into histrionics by characterizing this as a 'surprising failure,' it's not surprising," Hudson added. "It's the nature of networks, and especially of the Internet."
The fact is that "all security is a balancing act, not an absolute," she explained. "The only way to completely avoid these sorts of things is to implement so many security measures that nothing else ever gets done.
"Or unplug the computers ... which defeats the whole purpose of using computers in the first place, unless you like owning an expensive doorstop," Hudson concluded.
Risk Management
"Perfect security is impossible," agreed Chris Travers, a Slashdot blogger who works on the LedgerSMB project. "A determined attacker who is knowledgeable and capable cannot be stopped by any sorts of defenses."
Security, then, "is about risk management, not about preventing all conceivable attacks," Travers explained. "The fact that this has happened is a big deal but it is also to some extent something that will happen from time to time. The downloads need to be checked, etc., and this may be ongoing."
Ultimately, "what is important here is that there are layered defenses against the source code repos themselves being tampered with," he added. "Linux has good multilayered defenses here, and so this is not a major issue for Git-based projects.
"So, without knowing more, I don't see a reason to be concerned at present," Travers concluded.
The Time Factor
"There is NO SUCH THING as a perfectly secured site, period," echoed Slashdot blogger hairyfeet. "If you can get to it from the net it can be hacked; the only question is how much time will it take and will the admins notice the attempt before they get in."
The past year, in fact, has seen attacks on organizations "from governments to security firms," hairyfeet noted, so "what makes the kernel guys any better? Linux isn't magical, it is an OS. All OSes are extremely complex and nobody knows every inch of them."
The bottom line, then, is that "it all comes down to time, what software they are running, and a little luck," hairyfeet concluded. "It doesn't make them bad, or make the OS lousy, it is just a flaw, flaws get fixed. I'm sure they minimized the damage and restored from a good backup as is sound security practice."

do i need an extra capacitor to handle the second pair of registers?
You can connect as many 74HC595 chips as you want! But you will run into limitations due to complexity, power consumption and slow operation if you have very many chips connected. Remember that all the devices (LEDs, relays, light bulbs, whatever) will consume current when switched on, and that current will add up! Plus, with a bit-serial interface, it will take more time for each chip (8 bits) that you add to the system.
Does this mean I'm limited to a total of 70mA on all output pins
Yes, with those chips, it looks like you are limited to 70mA in total. As you say, just under 10mA per LED pin.
I love your pictures in the Make: pool on Flickr BTW!
