The month of June brings forth a lot of things to be grateful for. For example, this month holds the NBA finals and the first day of summer. What we're most happy for and the reason why we're here today is that June is the month we celebrate our Dads. Yup, Father's Day is only a few days away. And yes, you may have purchased, or made, the gift to give to the man who provided lots of guidance in life but we wanted to sprinkle a bit of style inspiration this week as we lead up to Sunday.
It's no secret that we at Pen & Cob love to switch things up when it comes to bowties. However, we've rarely taken a moment to 'big up' the other main attraction, the simple, yet sophisticated tie. You may think it is a bit cliché for Father's Day, but before you close the window, think about how a funky, colorful and vibrant tie can spruce up any old outfit. For example, a bright-colored abstract print with a slight sheen, can make your Dad a showstopper when paired with a plain textured shirt. FYI, the shirt can be short sleeved or long sleeved too, which makes it even better. Or how about a floral tie, kind of like a silk brocade that can be worn with that linen suit Dad has hiding in the closet for the perfect summer Sunday. Last but not least, one doesn't always have to reach for vibrancy, but instead a tie with a touch of texture that may seem 'Modest' but it's an easy go-to for mixing prints. The possibilities are endless.
So if you are still trying to find the perfect gift, remember a tie doesn't have to be cliché, but instead a cool way to switch things up…if you're up for the style risk. Remember, there comes a time when the children become teachers!
For the fathers, the men who are like fathers and the ones who are about to become fathers…Happy Father's Day from the team at Pen & Cob.

On the very day the Mac Book Pro was announced, I placed my order. In fact, the order was placed within 5 minutes of the Apple Store being re-enabled (it's typically disabled during such events). I was very excited to get it but all the orders got bumped back so I decided to cancel it and get a 20″ iMac Core Duo since it was available right away. On Tuesday I returned from school to find it sitting next to my desk.
If you have never bought a new Mac, then you might not appreciate the care and elegance with which Apple packages their computers. I've done it so many times that I expect it and hardly noticed the nice, well designed packaging. I had work to get done so I ripped it open, yanked out the goodies, and settled into hard core
work playtime.
After setting up the iMac on my desk, it created a significant problem. I already had the 20″ and 23″ Cinema Displays hooked up to the G5 dual and they commanded a large portion of my desk. Adding yet another 20″ display consumed what was left. To relieve the crowding problem, I have moved the 20″ into our bedroom for watching movies when connected to the laptop. That will work until it or the 23″ gets sold on eBay.
My intent for this system is to replace one of my dual G5 systems which I can then sell on eBay. The reason it may achieve that goal is that this new iMac supports monitor spanning. It can drive its own built-in 20″ display as well as my 23″ Cinema Display, providing me with the same amount of screen real estate I have now. Previous iMac systems were limited to mirroring when an external display was connected. Unfortunately, I must wait for the $19 adapter to arrive before I can use the 23″ with it.
Instead of using the default system install, I booted off the Install DVD and reinstalled the system with a few adjustments. Namely, I installed X11, XCode, and deselected all the additional languages. Formatting the drive and installing took a couple hours. When it was done, it prompted me to create an account which I did. Immediately after, it prompted me to add a picture to my account using the built-in iSight. Nice touch Apple!
While taking my account picture, I noticed that the iSight built into the iMac is considerably better than the one I purchased for use with my dual G5 and PowerBook. The resolution appears to be noticably higher and the light sensitivity and color balance is much better. I used to have to carefully control and adjust my lighting in the office so that the person on the other end didn't see a washed out blob. The built-in iSight works well under a much wider range of lighting.
Speaking of light, before I got far enough along to adjust the screen brightness, I nearly got a suntan from the light put out by the display. The LCD in this thing is seriously bright. I find that I prefer using it in the lower half of the brightness scale. I look forward to having a screen this bright in my Mac Book Pro, making the laptop much more usable outdoors. I've read that a lot of other people have also noticed how bright the new displays are. The difference is really quite remarkable when compared to my older Cinema Displays.
To determine if the iMac can fully replace the G5, it seemed best to put it to work. This week I had several clients clamoring for some web site development work which requires that I run several programs including Photoshop, Dreamweaver, and Tinderbox. To work on those sites, I would have to install the necessary software and get connected to my network and file server where the development versions of all the sites live.
I enabled the Airport and three networks showed up. That's not surprising, but my G5 and PowerBook never see any network but the one provided by my Airport Extreme Base Station. This is not surprising. It's well known that PowerBook and G5 systems have stinky wireless reception. The signals simply do not travel through metal very well, it's a cross we must bear. The Airport reception on the iMac is excellent, just like previous iMacs.
After connecting to my network via Airport, data access was good, but not nearly as fast as the G5 dual. Of course not, the G5 is connected by gigabit ethernet to the server. The file server is also a dual G5 with five 300GB drives (RAID 0+1) packed into it. File access to it is really fast, typically faster than reading and writing to a local disk. To resolve the network speed issue, I synced up the G5 to the server and shut it down. Voila, a gigabit cable was freed and the iMac happily connected at full gigabit speed.
Some time ago, I got tired of having a mountain of CD/DVD media in my desk so I made images of all the disks and moved them to the garage. The ISOs all live on the file server so installing software was quick and easy. While the programs were installing, I configured my Dot Mac settings and let it sync up all my email acccounts, Address Book, Calendars, and web bookmarks. Dot Mac really makes it painless to sync data across several systems.
A couple things about my programs. I wanted to avoid the installation of any software that is not Universal Binary. A surprising amount of software I use regularly is already UB. However, this is immediately unavoidable as many apps simply are not. Even if the software isn't UB, it still ran as well on the Intel based Mac. I say after having used Photoshop CS, DreamWeaver, AccountEdge, BBedit 7.1, Tinderbox, and MS Office for several days now.
When I say, "just as well," I mean that it runs it as quickly and gracefully as it did when I was running it on my dual G5. I find that to be quite remarkable. My dual G5 is really, really fast and rare indeed is the occasion that I'm waiting for it to keep up with me. On one of this weeks projects, I had to open dozens of Photoshop files, manipulate them, and then save them for web posting. Other than using a Mighty Mouse instead of my stalwart Logitech MX 510, I could scarcely tell I had switched systems.
Speaking of that Mighty Mouse, I'm still deciding if I like it as much as my Logitech. It has all the most important features (left & right click, expose, dashboard, vertical scroll) and the ability to scroll horizontally quickly endeared me, particularly in Photoshop. However, a feature my Logitech has that I sorely miss is forward and back buttons for browsing web pages. The Mighty Mouse is a very nice mouse and a monumental improvement on Apple's previous mice. Had it existed years ago, I never would have searched for a better one.
While I'm still on the positive aspects of this system, I need to point out that many aspects of the system are markedly faster than the dual G5. Booting is very fast. For reasons I do not know, running perl programs on a G4 or G5 were always slow to launch. After the perl interpreter had loaded, speeds were normal. On the iMac, speeds are extremely quick all the way around. It is as fast as running it on a high end dual P4/Xeon system running Linux or FreeBSD. I'm sure these gains are also visible in other programming environments so developers everywhere are surely pleased.
The other nice feature of this system is near silence. Other than the clicking sound made by the scroll wheel of the Mighty Mouse (which can be disabled), this system is whisper quiet. The dual G5 is also very quiet, typically generating less noise than the Dell laptop in our office. When it's warm (70s+) or I work it very hard, the G5 fans speed up enough that you can hear them and occasionally get loud for a moment or two. In several days of very warm (low 80s) Texas weather, I worked this iMac harder than normal and I still have not yet heard the fans on the iMac. This morning, I heard the fans for the first time. The dual G5 and Dell are both turned off and the LaserJet is sleeping so the office is dead silent. The fans on the iMac are just audible. What a pleasant system to have in the office, or even the den or bedroom.
For the most part, I am extremely pleased with the iMac, but there are a few things that need to be addressed before I feel comfortable parting with the venerable dual G5. That $19 mini-DVI adapter needs to come in so that I can hook up the 23″ to it. I seriously need another gigabyte of RAM. I got it with 1 gigabyte and after opening up Photoshop and a few other apps at the same time, I ran out of memory and began swapping. To prevent that from impairing Photoshop performance, I had to quit a few other programs.
My G5 and PowerBook both have 1.5GB of RAM and that has proven to be enough that I can have as many apps open as I want without it ever slowing perceptably. It's pretty common for me to have 3 or 4 web browsers open, Mail.app, iPhoto, iTunes, Address Book, Calendar, Remote Desktop, and then a few other heavy weights like Photoshop all open at the same time. On the iMac, 1GB seems to be the low end of practical. Thats just enough that you can open a memory hog like iPhoto or Photoshop and a few other apps without it swapping. Just logging in without any apps open uses about 450MB.
It seems that everything uses up a little more RAM on the Intel system. I'm sure that the non UB apps need more for Rosetta. Because I normally have Photoshop open with a few other programs I am using concurrently, like iPhoto and Dreamweaver, I'm not sure that 1.5GB in the iMac will be enough. I ordered another gig for $110. Having 2 gigabytes should take care of the only performance related issue I saw. I'll be keeping that in mind when I order the Mac Book Pro. If you are considering an Intel mac, plan on ordering the extra RAM right away.
The last issue I had is with the USB keyboard. This is early hardware so I expected some issues and found others also have this problem. It is described on this thread so I won't elaborate on it further. I have worked around it by installing a USB hub. I happened to have a couple of them so it didn't cost me anything but a little aggravation. If this is the worst of the problems that I discover, I'll remain quite pleased.
So, it would seem that once my mini-DVI adapter and RAM arrive, the G5 can get listed on eBay. It had been and remains a great system. I'll miss the ability to easily pop it apart and stick in extras like a bigger drive and the TV tuner & video capture card. For pro use (like heavy Photoshop, InDesign, or Final Cut users) I expect the G5 to remain king for a while longer. The big pro apps work fine on the Intel but no better than existing G5 systems. When all the pro apps arrive as UB, most everyone will want to switch. The new systems are faster, quieter, and use less energy.
Classic is gone. May it rest in peace. New users won't care and I suspect most others won't either. The only classic app I still use is Delorme Street Atlas and it only on rare occasions when I don't like the route Route 66 is offering. Now, I instead refer to maps.google.com. Should I ever need an old classic app, I can always run it on my other dual G5 (the file server).
Virtual PC doesn't work on the new Intel systems, leaving me with only one G5 left to run it on. I am hoping that is not an issue for long. I contributed to the WinXP on Mac project and hope that bears some fruit soon. I would like to have Windows available for the few times a year when I need it. However, I want to run it on my mac, in a protected environment so I don't have to worry about script kiddies installing a rootkit on it.
Someone will miss the G5 though. Kayla really likes the big handles on it, and the little tongue that frequently sticks out at her when she's standing in front of it. She loves the sound her nails make when she scratches them along the grating on the front.

Everyone who knows watches knows that best fake Breitling is perhaps the brand most closely affiliated with flight and pilots' instruments for the wrist. It therefore makes great sense that this is the company that would pioneer the way for aviation sponsorships. In fact, it was in 2003 that Breitling's owner, Teddy Schneider, joined forces with team leader and manager, Jacques Bothelin (who had been part of the Patrouille Martini team) and put together the Breitling Jet Team.
This year marks the team's second year on the American Tour circuit, and its last before heading back to Europe, where aviation aerobatics fans are anxiously awaiting the return.
The team is an incredible aviation force that flies seven jets – flying just 10 feet apart from one another – in perfect formation, and completes a host of thrilling, precisely timed aerobatic maneuvers that have onlookers staring in disbelief at the startling sky moves that include full 360-degree rolls, straight-down dives, loops, barrel rolls and a host of other feats that somehow one just can't equate with a machine in the sky.Cheap fake breitling watches for sale UK.
The reality is that this type of flying is a blend of perfect precision by those in the cockpit – seemingly as one with the metal around them – bringing man and machine together. The pilots fly their jets at speeds of more than 500 miles per hour, and withstand G forces of 5 and 6 on a scale that would have most of us feeling sick.
Indeed, while it looks like an air show of fun and excitement, it is instead an extremely precise and exacting orchestration of man and machines. The fit of the jet team and replica Breitling watches makes perfect sense. Breitling is always on the pioneering side, the cutting edge, when it comes to bringing even greater ingenuity and excellence to its flight instruments and other timepieces.
In fact, of late, Breitling has introduced new ultra-light materials, and connected watches; it has brought the tried-and-true slide-wheel and navigation tools to new heights in new and updated versions and has finally been able to bring the potentially life-saving Emergency watch to America (this watch, when activated, sends out a distress call on a special highly monitored frequency). The brand also offers the fake Chronomat 44 Breitling watches Jet Team American Tour Limited Edition watch and the Chronomat GMT Breitling Jet Team American Tour Limited Edition – to celebrate these two glorious years.
If you are in or nearby a city when the Breitling Jet Team is flying – I urge you to go. It is a site not to be missed. The schedule for the rest of the year includes stops from late June through October in places such as Salt Lake City, Utah, Oregon, British Columbia, Michigan, Toronto, Miramar, San Francisco and Huntington Beach.

Full Fact launch 'Need to Know' project
RSS fellows are helping to launch a new initiative with fact checking organisation, Full Fact, which aims to bring together researchers and experts to improve the information available to the public on often-complex issues such as healthcare, immigration and public finances.
The initiative involves Full Fact teaming up with the Economic and Social Research Council (ESRC), the UK Statistics Authority and the House of Commons Library. The organisers want the initiative to make it easier for the public to understand issues like NHS funding and whether enough houses are being built.
National Statistician John Pullinger and ESRC chief executive Jane Elliott - former RSS president and RSS fellow respectively - are both leading the initiative, along with House of Commons Librarian Penny Young and Full Fact director Will Moy. 'If the EU referendum taught us anything, it's that expertise and experts should be set out as part of the furniture of public debate early on if they're going to have an impact,' said Moy. 'We're starting now so we've got the data and analysis we need to answer the public's and other decision makers' questions before the heat of the next election.'
Two RSS Council members are also directly involved - Mike Hughes, who acts as statistics adviser to Full Fact, and Simon Briscoe, a Full Fact trustee.
At the initiative's launch last week, around 100 attendees from government departments, the media, researchers and other organisations took part in a workshop in eight topic areas, such as healthcare, housing and education. In each topic area, the key issues and communication gaps around those issues were discussed. The workshop will feed into an action plan agreed by the four partners.
Hetan Shah, RSS executive director, explained why the RSS welcomes the initiative. 'It's good to see this project that will help producers of statistics think about the issues that the public care about and want data gathered on,' he said. 'This will help ensure public debates can be informed by good evidence.'
Full Fact has produced a video which explains more about the wider Need to Know project, and has published case studies on fullfact.org/needtoknow.

Isolation, Synthesis and Structure-Activity Relationships of Antifeedants against the Pine Weevil, Hylobius Abietis
Sammanfattning: The large pine weevil, Hylobius abietis L., is a major insect pest on conifer seedlings in northern Europe. Due to its feeding newly planted trees get girdled, resulting in high seedling mortality (up to 80%). As a consequence great financial losses to the forest industry occur. Today the seedlings are protected with the pyrethroid insecticide cypermethrin. This insecticide is toxic to aquatic organisms and is, from 2010, prohibited for use in Sweden by the Swedish Chemicals Inspectorate. An alternative to insecticides is to protect the seedlings with antifeedants, compounds that, either through taste or smell or both, deter the weevils from feeding. This thesis describes the search for and the synthesis of such antifeedant compounds.Bark extracts of several woody species, known to be non-palatable to the weevil, were prepared and found to display antifeedant activity against H. abietis. The major chemical constituents of the extracts were tested for antifeedant activity. Antifeedants such as eugenol, 2-phenylethanol and benzylalcohol, but also feeding stimulants such as ?-sitosterol and linoleic acid, were identified. An extract of linden bark, Tilia cordata, was shown to contain nonanoic acid, a highly active antifeedant. Other aliphatic carboxylic acids were also found to display high antifeedant activities against the weevil, both in laboratory and in field tests.The enantiomers of dihydropinidine, a piperidine alkaloid present in several conifer species, were prepared by dimethylzinc mediated allylation of 2- methyltetrahydropyridine-N-oxide. When tested in micro feeding assays, no difference in antifeedant activity was found for the enantiomers. In a field test high antifeedant activity, comparable with that of the presently used insecticide cypermethrin, was found for (±)-dihydropindine. Other naturally occurring piperidine alkaloids were synthesised and also found to display high antifeedant activities in laboratory tests.Structure-activity relationships were evaluated for methoxy substituted benzaldehydes, benzoic acids and cinnamic aldehydes, -acids, -esters and -alcohols. While the carboxylic acids were inactive or even feeding stimulants, the aldehydes were the most active antifeedants

Motivate Yourself
Many people that want to get back into shape start a fitness program to help them get fit. You might want to improve the state of your health, or lose a few pounds. Maybe you just want to have more energy!
The main problem that most people have is sticking to a fitness program. Motivation is their greatest obstacle. If you want to stay physically fit, or at least get on the right track with better healthier you, here are a few suggestions that can help you get in shape once again.
Establish a Routine
There are many components to a good exercise regimen including the proper amount of exercise and the right amount of rest. If you are missing these essential ingredients, you will not succeed as they are necessary for you to progress forward. You need to challenge your body! If you do not, you won't break the muscle tissue down as necessary to see results.
You also need to have the muscles rebuild. This is a key component of benefiting from this process. If you do too much training, this can actually hurt you if you do not rest. You can also slow your training process altogether. You have to take a break and doing aerobic exercise and strength training to see improvements. The exercise programs should be staggered, not doing the same one every day. You need to rest one or two days as well.
Consider Workout Intensity
Instead of doing cardio workouts that go for a long time, that are light or moderate in intensity, go for interval training for your workout routine. The key is to modulate between high and low intensity workouts during the interval training. You can do this with an elliptical machine or a treadmill. So rather than jogging around a track at a steady speed, you would alternate between walking and sprinting. You will not only burn fat, but your metabolism will go higher which is what you want. Shorter workouts, plus better health benefits, is what you will get by doing this. As you get older, this is very beneficial for not only your heart, but maintaining your growth hormone levels.
Start Walking
Did you know that walking is one of the simplest but effective workouts you can do and it doesn't have to cost you anything? Walking has many advantages. You can walk regardless of where you live. You can walk around your neighborhood, in the mall, a track, sidewalks, and practically anywhere. No matter what your current level of fitness, you can start walking. Try getting started gradually and in flat or level surfaces. As your fitness level gets better, you can start walking faster and farther.
You can even start walking uphill. Walking doesn't have to be a solitary activity. Invite your partner, a few neighbors, or even your friends to go walking with you regularly. The recommendations we've covered in this article are just some of the strategies you can use to improve your level of fitness. Try to go for an exercise program or diet that will help you achieve your goals. Always look at what you are achieving everyday. You also should be honest with yourself about what type of program you're most likely to stick with in the long run.
