Luctor et Emergo, reads Zeeland's slogan: "I struggle and I emerge", a reference to the interminable battle the province has waged with the sea. As its name suggests, the southwestern corner of the Netherlands is bound as much by water as land. Comprising three main peninsulas within the delta of the Rijn (Rhine), the Schelde and the Maas, this cluster of islands and semi-islands is linked by a complex network of dykes. This concrete web not only gives protection from flooding but also forms the main lines of communication between each sliver of land. The northernmost landmass, Goeree-Overflakkee, a little south of Rotterdam, is connected by two dams to Schouwen-Duiveland, while further south are Noord and Zuid Beveland, the western tip of which adjoins Walcheren. Furthest south of all is Zeeuws Vlaanderen, lying across the blustery waters of the Westerschelde on the Belgian mainland.
Before the Delta Project secured the area, fear of the sea's encroachment had prevented any large towns developing and consequently Zeeland remains a condensed area of low dunes and nature reserves, popular with holidaymakers escaping the cramped conurbations nearby. The province also has more sun than anywhere else in the Netherlands: the winds blow the clouds away, with spectacular sunsets guaranteed. Getting around is easy, with bus services making up for the lack of north–south train connections, though undoubtedly the best way to see these islands is to cycle, using Middelburg as a base and venturing out into its environs.Read More
Middelburg's festivals
Middelburg's festivals
One of the town's most colourful festivals is Ringrijderij, a horseback competition where riders try to pick off rings with lances. It takes place in August at the Koepoort city gate near Molenwater, and in the central Abdijplein on one day in July; check with the tourist office for dates. Another major draw is the annual Mosselfeesten, a weekend in the second half of July devoted to celebrating the arrival of the fresh black mussels, of which Zeeland is particularly proud. The festival takes place around the Vlasmarkt, with live music and restaurants offering their own version of this regional speciality.
Cycling around Middelburg: along the Walcheren coast
Cycling around Middelburg: along the Walcheren coast
The coast north and west of Middelburg offers some of the Netherlands' finest beaches and excellent walking and cycling, although on midsummer weekends parts of it are mobbed with crowds of Dutch and German holidaymakers. Countless cycling options make the most of Walcheren's handsome coastline, with plenty of refreshments en route. With limited public transport available to transport bikes, most routes are best completed as loops. As a rule of thumb, red cycleway signs indicate utility paths, often parallel to a main road, while the green signs denote more scenic alternatives.
Possible day-trips include cycling west to Domburg, picking up signs to the Domburg HI hostel and continuing through the woods to Breezand. A cycleway follows the polder to Veere, from where you can ride alongside the Walcheren canal, cutting back to Middelburg. Alternatively, pick up the same canal out of town to Vlissingen, joining the cycleway that runs between dune and woodland to Zoutelande and Westkapelle: there's a fabulous stretch of dyke to cycle along in the direction of Domburg with spectacular sunsets out to sea and a photogenic lighthouse. A red-signposted cycle path leads directly back to Middelburg.
Cycling around Zierikzee
Cycling around Zierikzee
There's plenty of scope for exploring the countryside and coastline around Zierikzee by bike. To put colour in your cheeks, you could follow the bike lane over the wind-tunnel-like Zeelandbrug, a graceful bridge that spans the Oosterschelde south of Zierikzee, and is one of the longest bridges in Europe, at 5022m. Refreshments are available in Colijnsplaat on the other side: prevailing winds will be against you on the way out, so you can expect the journey back to take half the time. Alternatively, Dreischor, 8km northeast, makes for a pleasant half-day bike ride from Zierikzee. Here, the fourteenth-century St Adriaanskirche is surrounded by a moat and lush green lawns, encircled by a ring of attractive houses. Complete with waddling geese and a restored travalje (livery stable), it's an idyllic setting – although busy at weekends.
The Delta Project and the Delta Expo
The Delta Project and the Delta Expo
On February 1, 1953, a combination of an exceptionally high spring tide and powerful northwesterly winds drove the North Sea over the dykes to flood much of Zeeland. The results were catastrophic: 1855 people drowned, 47,000 homes and 500km of dykes were destroyed and some of the country's most fertile agricultural land was ruined by salt water. Towns as far inland as Bergen-op-Zoom and Dordrecht were flooded and Zeeland's road and rail network was wrecked. The government's response was immediate and massive. After patching up the breached dykes, work was begun on the Delta Project, one of the largest engineering schemes the world has ever seen and one of phenomenal complexity and expense.
The aim was to ensure the safety of Zeeland by radically shortening and strengthening its coastline. The major estuaries and inlets would be dammed, thus preventing unusually high tides surging inland to breach the thousands of kilometres of small dykes. Where it was impractical to build a dam – such as across the Westerschelde or Nieuwe Waterweg, which would have closed the seaports of Antwerp and Rotterdam respectively – secondary dykes were to be reinforced. New roads across the top of the dams would improve communications to Zeeland and Zuid-Holland and the freshwater lakes that formed behind the dams would enable precise control of the water table of the Zeeland islands.
It took thirty years for the Delta Project to be completed. The smaller, secondary dams – the Veersegat, Haringvliet and Brouwershaven – were built first to provide protection from high tides as quickly as possible, a process that also enabled engineers to learn as they went along. In 1968, work began on the largest dam, intended to close the Oosterschelde estuary that forms the outlet of the Maas, Waal and Rijn rivers. It soon ran into intense opposition from environmental groups, who pointed out that the mud flats were an important breeding ground for birds, while the estuary itself was a nursery for plaice, sole and other North Sea fish. The inshore fishermen saw their livelihoods in danger too: if the Oosterschelde were closed the oyster, mussel and lobster beds would be destroyed, representing a huge loss to the region's economy.
The environmental and fishing lobbies argued that strengthening the estuary dykes would provide adequate protection; the water board and agricultural groups raised the emotive spectre of the 1953 flood. In the end a compromise was reached, and in 1976 work began on the Stormvloedkering ("Storm Surge Barrier"), a gate that would stay open under normal tidal conditions, allowing water to flow in and out of the estuary, but close ahead of potentially destructive high tides.
Delta Expo
Completed in 1986, the fascinating Delta Expo, signposted as Waterland Neeltje Jans, is on the Stormvloedkering. It's only once you're inside the Expo, though, that you get an idea of the scale of the project. It's best to start with the half-hour video presentation before taking in the exhibition, which is divided into three areas: the historical background of the Netherlands' water management problems; the technological developments that enabled the country to protect itself; the environmental consequences of applying the technologies and the solutions that followed. The Surge Barrier (and the Delta Project as a whole) has been a triumphant success: computer simulations predict most high tides, but if an unpredicted rise does occur, the sluice gates close automatically in a matter of minutes. If you cycle to the Expo on cycle route LF16, you'll run alongside open beaches and dunes, past wind turbines and onto the storm barrier itself, with ample opportunities to peer into the sluice gates: allow for blustery winds on the way back.

The United States and Mexico welcomed a record number of Canadian travelers in 2011, receiving 21 million and 1.6 million overnight visits respectively.
US Department of Commerce data shows more than one third of the record 62 million foreign visits to the US last year originated north of the border, confirming Canada's status as the biggest source market for American tourism ahead of Mexico (13.4 million visits) and Great Britain (3.8 million).
Taking advantage of the strong loonie last year, Canadian travelers also generated an unprecedented $24 billion in tourism spending in the US, up 15 per cent on the year before.
And with a new trade agreement expediting the cross-border process between the two nations now in place, visitor numbers to the US from Canada are expected to rise even more.
Further south, Canadians made more overnight trips to Mexico in 2011 than in any other year.
According to statistics provided by the Mexican Embassy in Ottawa, 1.5 million visits were made to Mexico by Canadians in 2011, reflecting an increase of seven per cent over 2010 and 29 per cent over 2009.
Picking up where last year left off, total travel from Canada in January grew by 6.7 per cent to 2.6 million trips, the Canadian Tourism Commission revealed.
The number of Canadians visiting the US during January increased by 8.7 per cent compared to the same month last year, while travel to overseas destinations grew by 4.1 per cent to 1.1 million trips.
The new data comes just weeks after a survey found that sentiment for Canadians among Americans was at an all time high.Ninety-six per cent of respondents in the annual Gallup poll said they held 'very favourable' or 'mostly favourable' views of Canadians, the highest rating measured for any country since the question was first posed 25 years ago.

If one is not in any position to pick the tools one uses, then it would be prudent for any engineer to learn the limitations of the tool to ensure that none of those limits are exceeded. I will wholeheartedly agree: use of a particular language, tool or environment etc. it not in itself a WTF, but making non-robust tools available for easy use by non-technical personnel definitely is.
This discussion about MySQL is a prime example of this. Without knowing about the limitations on triggers, and without familiarising myself with the ACID compliance (DB admin is not within my main field of expertise), I would have been blissfully ignorant about all this.
However, knowing that more than 32 levels of trigger are a Bad Thing on MySQL, I am a wiser man.
Having said that, my intuition already informs me that 32 levels of trigger is probably a WTF however you cut it.

I read it as: noone wants to see those updates made without some decent sourcing to back it up. Understandably, they're not interested in "This says A, this says B, and I say A+B=C" - they're attempting an encyclopaedia, after all. As I mentioned earlier, most sources seem to say that InnoDB is ACID compliant, therefore, as far as Wikipedia is concerned, the proposition might not be entirely true but it is the only one that is properly "verifiable" (by their definition).
tl;dr it's not enough to provide the pieces, you need someone else to have completed the jigsaw.

Yes. It's far better than CVS and SVN, and branch creation is trivially simple, but non-trivial merges (e.g. between two lines that don't directly descend from each other, but have a common ancestor) don't always happen cleanly.
And when there are merge conflicts, it does a 2-way diff (yours and the other branch), instead of a 3-way diff (adding in the common-ancestor revision) which sometimes makes it hard to figure out what changed without extra work.
Finally, git has little concept of revision history for individual files, preferring to work instead on the entire repo. So I can't easily get a list of the last 5 changes to a single file, or diff the current version against the previous version. I have written scripts to do this, but I don't think I should have to.

32 levels is MSSQL and no it is not *necessarily* a WTF to have them.
(mysql is the other problem)
I do agree that I haven't yet found a good reason to model anything using trigger chains expanding further than 32, but it makes sense that there would be extremely complex systems for which the best logical model would make extensive use of triggers.

This feature doesn't require a distributed system.
Perforce (sorry again for sounding like an ad) lets multiple users check out the same file at once. When submitting (i.e. "committing" in git terminology), the first one in has no issues. The others, when submitting are told that the file changed. They then issue a "resolve" command to merge the changes (using a 3-way diff to deal with conflicts) and re-submit once everything is merged satisfactorily.
So your sequence ends up as:
Sync A. Sync B.
A edits. B edits.
Submit A.
Submit B - generating error
Sync B - informing B about changes that need to be resolved
Resolve B - merging the diffs
Submit B - which now succeeds
All this using a centralized server.
Git does the same thing, except that you get the errors and have to perform the merges at "push" time instead of at "commit" time.
The ability to have multiple people editing files at once is critical for any project of non-trivial scope, but the feature can be implemented using centralized servers as well as with distributed systems.

Looks like you read the page.
It's all a matter of subject knowledge:
- If you understand math, you will accept that anyone writes 1+1=2
- If you understand ACID and MySQL info pages, you will accept that MySQL InnoDB is not acid compliant
There is no jigsaw, the information is right there without any modification IF you know the subject.
Actually, it was closer to "you don't have to use version control for your class projects, but it's a good idea. Here's how to set up RCS..."
The same prof also recommended learning either vi or emacs. That was a great course.

O worked in one shop where the code was label prog.old, prog.new, prog.bad. The really hard part was finding the correlation between source and binaries. I instituted simple version control ( whatever came native in Unix, don't remember what is was ) and life became sane.
No, it doesn't do the same thing. B gets fully committed using git (or other modern DVCSes). This is a nontrivial difference, since there's no risk of losing B's changes during the merge. This is also one of the problems with svn.
I agree that there's no reason why not, but I'm not aware of one that does it like the modern DVCSes do, including Perforce, at least based on your description.
Great article... please post some more on various software engineering topics :)
However i got some serious questions.
1. Can anyone give me a good example where "Branching by Rule" would feel like the right thing to do? I can only come up with "Branching by Exception" examples.
2. The author seems to dislike distributed source control a little but i had one scenario in the past where i wished i had it and i would like to hear your thoughts.
Let's assume i'm on the train (no internet connection) and i want to work on two tickets. I got all the code and environment set up on my laptop so i'm good to go.
With a distributed source control system i would finish the first ticket and commit it locally with some appropriate meta information to close the ticket too.
With a traditional source control system i can either fix both tickets together and commit them together or i could create two branches in advance one for each ticket just to avoid mixing those two together which seems like alot of overhead if they are just small bugfixes.
What are your thoughts on that? How would you approach this situation?

You are correct about git having little concept of individual files. The upside is that it makes it easy to follow code that is moved around between files. This does not however make it hard to follow individual files. Are you are running an ancient version of git? It has been easy to track file changes for years.

As a rule of thumb, you should Branch By Rule when most of the releases are considered exceptional under Branch by Exception. There are a lot of scenarios for this, but here's one: 50 developers split into 6 teams that maintain a large, application that's released on a monthly basis. Each team would work on a feature that's planned for a release 2-, 3-, 4-, 5-, or 6-months out.
I'm more frustrated by the buzz and excitement about it. The "delayed merging" and "easy shelving" has existed in propietary systems (Perforce, Accurev, etc), and could have easily been added to Subversion clients.
Heck, Subversion could have even added the one benefit of distributed systems (offline history viewing), but instead, we just started from scratch again with Git/Mercurial/etc.
It's like sea mammals: one step forward (underwater, woo hoo!), several steps back (no gills).

Git is considered to be good at merging, so I'm not sure what specific issues you've been having. I think there's a bit of terminology confusion here: a three-way diff means that the merging code compares both versions to an ancestor version (all source control systems work this way), but it doesn't necessarily mean that those ancestor lines are displayed with a merge conflict.
Git can be configured to display the ancestor lines (git config --global merge.conflictstyle diff3) but it's unfortunate that this isn't the default.
For viewing the last 5 changes to a specific file, try git log -n 5 -p filename.txt

I agree that developers dont know SQL, and that mysql isam is not ACID.
But access is not bad, its only a tiny database.
Except that outlook uses access (its a variant of blue jet that access use), and it work good (when you dont have more than 2GB database of craper emails, then you need exchange).
Also, the windows instaler uses access to install the entire windows, office, and visual studio, and whatever uses msi installer, uses the red jet, its a variant of blue jet.
Access (JET) is full ACID compliant, except when you have more than +-512 locks (limited by filesystem), it will broke. It suports SQL also.
Crap is what people has done with it. partly because classic asp and "webdevelopers" that think they can use a database, these people ruins everthing to shit.
People like to blame thinks that they dont know.
I use JET to store temporary transactions when my (of my client) central sql server goes off-line because of lan/net problems (cheapo equipment, and eletromagnetic interference). For this purpose its is very god at it.
I agree also that JET is useless for most softwares, because its so simple and limited. But you cannot consider a knife to be a worse thing if you need to cut a tree.

Silly (and possibly deliberate for the sake of being obstreperous) misunderstanding. Javadocs are actually part of the code and are generated automatically and dynamically. As such, this documentation is, by default, part of the source code itself and this aspect of the documentation is subsumed into the source code version control system.
By "documentation" in the context of "what ought to be stored in the document version control system", we are talking about standalone documents, which are written either by or for the customer, which define what the application is supposed to do in the first place. It consists of things like invitation to tender, project initiation documents, purchase agreements, project plans, records of meeting minutes, technical architecture documents, business requirements, technical requirements, migration strategies, UAT strategies, and so on.
I would be prepared to agree that writing it in Word (and Excel) is "wrong. Way wrong" except that in order to be able to do business with our potential customers at all we need to be able to generate and receive documentation in such a format as the customer is prepared to work with. In every single project in which I have been involved, at least some documentation is written using Word and Excel.
Nasty as this is, it is a business truth which is ultimately futile to try and circumvent.

Fixing old systems is not the Open Source Way. Start by assuming everything made before now is utterly compromised and kludged by well meaning but clueless engineers trying to fix fundamental problems that simply can't go away without rearchitecting.
Sometimes it is even true.
Gills are awesome if you're not endothermic. Otherwise, they're a bit like running your blood supply through a pair of bloody great heatsinks.
Tuna and sharks and probably other species have some sort of awful hack in the form of clever heat exchangers that let them have a body temperature a couple of degrees above ambient (which enables them to be a bit more energetic than other species) but it isn't going to be any more than a half-arsed attempt at fixing a fundamental problem with the architecture ;-)
Sea mammals on the other hand get to be quite adaptable to a range of temperatures and environments, they can be very effective predators and they get to have penetrative sex. That's a bit of a killer app, as I'm sure you'll agree.

Looking back on it, I think the reason I stuck with it so long was that I was actually enjoying the challenge, and it appeared at the time to be an opportunity to add some proper quality. Unfortunately that sort of relentlessness eventually takes its toll and you change your attitude towards it.
Wouldn't it be great to have a place where the Git/Maven/Hibernate/you name it fanboys would not pollute everything with their belief confessions?
Lack of meaning in your work? Finally something you feel you are ahead with?
That alone make me dislike Git (not too mention its terrible user interface, the lack of handling empty folders, partial checkouts, and pushes,... )
I've worked on both proprietary and open-source projects, and I've had to submit patches to someone else and hope they're ultimately included in the shipping product (and fix them and resubmit if they're rejected) in both cases. It's called code review, and proprietary developers do it too.
The main difference between open-source and proprietary development that I've seen is that proprietary products have multiple standards for quality and use different standards on different branches in the same SCM repo. If a customer is paying for an ugly hack, they may get such a hack in their branch, while the same patch might be rejected by the main product team--but that's just like any patch for an open-source project that gets shipped in a product somewhere, but isn't merged upstream.
It's possible to set up a DVCS as a drop-in replacement for a non-distributed SCM, but doing so wastes the opportunity to do process flow improvements that DVCS can enable. Since a DVCS 4th-dimension object can physically live anywhere, there's no reason why integration, build, QA, production, custom development services, and major product revision branches can't have their own repos with stars of users around them--and plenty of reasons why they shouldn't all necessarily share one giant churning burning repo, no matter what SCM you're using.
No one should start a new project on SVN today. Subversion doesn't just need a central server with excellent network connectivity--it needs a central server 150 to 200 times the size of the equivalent git server for program source code, and that server needs a low-latency network link to its users as well as a high-bandwidth one. If you have a large product, that kind of waste puts stress on every system near it, from storage to backups to IT hardware budgets to network operations staff.
Isn't it advisable to avoid shiny-new-toy syndrome when it comes to source and revision control?
Re: Source Control Done Right
2011-09-08 12:03 • by David C. (unregistered)
It really is the same thing. When you push your changes to the parent repo, you need to merge your changes with the other changes, and resolve conflicts.
The distributed systems preserve individual local changes because each person works with a local copy. Effectively, every client is a separate "shelf" branch.
A centralized system can do the exact same thing if every developer creates his own private branch. He can periodically merge the parent into his branch, similar to a "git pull", commit his changes to his branch without conflict, and then merge his changes back to the parent, resolving conflicts, similar to a "git push".
Same functionality, different command sequence. This applies equally well to any VCS that allows developers to easily create/merge branches at will, whether they are distributed or centralized.
Re: Why the tools matter.
2011-09-08 12:24 • by David C. (unregistered)
Thanks. I didn't know you could make it show the ancestor lines with conflicts. IMO, that makes it much much easier to resolve said conflicts. I assumed, because it wasn't showing the ancestor, that it didn't use it in the merge process either. I'll add this configuration option to my current git clients (My current work involves git, which has been quite a learning curve, compared to Perforce, which my previous project used. But not nearly as scary as ClearCase, which is also used here.)
WRT viewing changes, what I'd like to do is what I frequently did with Perforce. Over there, I could type "p4 diff foo#4" and it would show me the diffs between the current version and the fourth commit on the current branch.
"git log -n 5" shows me the most recent five commits, but not the diffs.
I wrote a perl script to give me the functionality I like. My "gitediff" script allows me to type "gitediff foo.c#-5" which will copy the fifth-most-recent commit to a temporary file, launch emacs with that and the current file, and start an "ediff" to let me compare them.
The script for this was not hard to write, but it wasn't trivial either. It does a "git log" to get the commits for a file, and numbers them. Then it counts the number of edits provided as an argument to get the commit ID string for that revision, then does a "git show" to extract the file before handing it off to emacs.
It's about a 230 line script for producing all kinds of diffs using git:
gitediff foo - compare foo against the latest committed version (HEAD)
gitediff foo#<ver> - compare foo against a specified version
gitediff foo#<ver1>#<ver2> - compare two revisions of foo
where <ver> may be either an integer - representing a sequential commit on the current branch, or a negative integer - representing the most recent "nth" version, or a git commit string.
I had to write the logic for this because the built-in syntax is repo-based instead of file-based. For example, HEAD~5 shows the file as it was in the fifth-most-recent commit, even if the file in question didn't change since then. In contrast #-5 (in my script's syntax) represents the fifth-most-recent change to the specified file, even if that change took place hundreds of commits ago.
If people are interested, I can post this script for others to enjoy. Or maybe people can point out an easier approach to the problem.

You need the -p flag to make "git log" show diffs. It'll show one separate diff for each commit. I don't think there's a one-liner to view the combined diff across those versions though, short of specifying the file name twice and using shell trickery:
git diff $(git log -n 5 --pretty=format:%H filename.txt | tail -n 1) HEAD filename.txt
Which I suppose is part of what your script does. So you're right, git doesn't provide the best tools for that sort of thing.
I think you meant here that it does not by default display the ancestor version in merge conflict markers, because Git always use 3-way merge when merging branches. You can make Git to include ancestor version either by configuring it by setting `merge.conflictstyle` config variable to "diff3", or run `git checkout --conflict=diff3 file`.
You can: `git log file`, `git diff HEAD^! -- file` (see git-log manpage for details on history simplification wrt former).
Are you being deliberately dense? It truly isn't the same thing.
You do not have to do that merge. It's possible to have multiple anonymous branches (at least with mercurial, and I'd assume for most others, too).
Yes, it is possible to get the same end result with a lot more work by the users, and assuming that they always follow this pattern. But that's the problem. No one really does (it's just not the way humans function). It's a case of a tool making a common problem easier to solve. So far, I'm not aware of a centralized VCS that does it.
TRWTF is "WTF is this article doing on the TDWTF?"

After showing how it's done wrong all the time i appreciate they show how to do it right once in a while.
You can find good example of feature branch (lots of branches) approach in last part of Eric Sink Version Control by Example (available on-line). Git development itself makes use of feature branches.
In short: using feature branches allows you to select which features to include in next release, and which are to be postponed.
"Delayed merging" and "easy shelving" is only a subset of workflows that DVCS allow.
Also Subversion made some design decisions which cannot work in distributed system, like global revision numbering (requires central numbering authority), and some bad design decisions, like "branch / tag is copy" (following Perforce AFAIK)... which makes branch deletion and merging complicated, and tags next to useless.
Starting from scratch (like in case of Git) was the only sensible choice.
Partial checkouts are available in modern Git (though not partial clone).
I don't know what you meant by ", and pushes,..." there.

It is not the same thing, as you are not forced to push after each one commit.
Or how will centralized system solve this:
I am far away from workplace (maybe on my vacation in other country) with my NB set up, but without (reliable/usable/any) internet connection. There is a big problem with deadline soon after my leave ends, so there is no time to solve it AFTER return to work, but there is a time to connect to company net before that deadline.
The problem consist of couple small unrelated subproblems.
With git I would simply make a branch for every such subproblem, work in the branch, make a lot of commits, evetually even merge all those branches together in the end. Then after return to work, I would just merge master from server, resolve conflicts (if any) and push back - maybe only seconds of work.
With centralized VCS I would probabelly be stuck on the same start with making all those branches, not talking about unability to commit in those branches. (and to eventually undone some bad decisions as VCS allow, when it works).
Just because of missing connection I am effectivelly losing better half of the functionality of VCS on centralized systems.

You don't have to merge after each commit with a centralized system either. It's only required if everybody is working from the same branch.
Your distribution is simply creating extra branches behind the scenes. There are no semantic differences.
You talk about your git solution being to create a bunch of branches for your tasks. Centralized systems all allow this. I do it all the time. And when you're done with a branch, you merge it back to the parent, which will make you resolve conflicts.
As for "not forced to push after each commit", why does that change antying? The server maintains all the branches (including the ones you create while working). It won't conflict with anything else unless others start working with your branches. The only potential advantage here is not needing the network bandwidth at commit time.
You seem to be hung up on the fact that some centralized systems make it difficult to operate with hundreds or thousands of branches in flight at once. I know that some of the most popular free ones (like CVS) fall over and die under those circumstances, but that's a problem with specific products, not with the concept of a central server.
Distribution lets people commit changes while disconnected from the network, and this is useful for many applications, but it doesn't create any other capabilities.
Re: Source Control Done Right
2011-09-12 19:32 • by gilhad (unregistered)
No, it does not. It creates the branches on client, not on server, so I can do it offline. In VCS i cannot do that.
And I can create how many branches I want and do not polute the shared system with them.
But only if you have good connection
Only if I am online.
While in DVCS it simply does not conflict, regardless on what others do or do not.
Which allows me to commit as often as I need, whithout caring about resolving some conflict. And modify as much files as I need without making problems to all others.
Also the problem with concept is the connectivity, the space wasted on server and the difficulty of arranging safe cooperation of many developers working at the same project at one time
It also allows people to share the changes in more ways, that are possible (or acceptable) in centralized VCS.
Some things can be "emulated" in centralized VCS with a lot of unnecessary work, but usually the centralised VCS are ment to solve different and restricted problem.
Re: Source Control Done Right
2011-09-12 19:49 • by gilhad (unregistered)
Lets say (as happened to me) that there are three programmers working on one system. Then they deside to part, so two will continue on the system and the third will fork the system as different project. They diveded the company they formed and went away.
In DVCS the third simply removed one line of his configuration and was free.
In VCS the third should setup new server (including the need for HW to run it), copy over the full project with all history and then change the configuration to the new server.
But lets continue: then the second parted with the first and had to undergo the same task.
But later the second and third formed another pact and wanted to continue developing together, while keeping their respective history.
In DVCS it just needed one address to configuration and that was all for the setup. I do not know, how to manage that simply in centralized VCS.

There is a built-in diff-tool in MS Word (since it can/could do versioning on its own), so if your versioning system supports calling third-party diff-tools, it shouldn't be any problem having the document in source control.

This is quite possibly the most ridiculous argument in favor of DVCS I've heard to date. DVCS saves a few hours off of the untold hours needed to dissolve a business?
If this is your workflow, then you're not developing software. You're hacking.
There's nothing wrong with hacking, but it's a different world than commercial software development.

If I remember correctly, then parting the company took less effort, than to setup SVN archive. A less working time too.
But the point was not leaving company, the point was easy forking and merging projects. Could happen even without company to start with :)

PORTSMOUTH -- Check out facebook and you'll see a number of school districts who gave a shout-out to their 2013 grads.
The districts posted congratulatory messages and pictures, hoping to make a big impact when students see their friends' achievements.
"For students to be graduating from high school in the city of Portsmouth, it is really a big deal," one Portsmouth taxpayer said.
But several people told 13News Now they had a problem with the way Portsmouth Public Schools honored its top graduates.
The cash-strapped school district that was forced to cut its budget by $6 million this year took out a full-page ad in the Virginian Pilot costing $3,000- and You Paid For It.
"Okay, I do not agree with that," another taxpayer said. Why? "Cause it's taxpayer money," the man added.
Superintendent David Stuckwisch repeatedly turned down a request for an on-camera interview.
In an email, Stuckwisch said the purpose of the advertisement was to point to the success that occurs in their schools. "These advertisements are not dissimilar to other graduation-type ads that run in the Pilot each spring," Stuckwisch wrote.
In our investigation we found that Newport News Schools spent more than $1,200 to tout their students' successes and Hampton schools spent $1,300.
But Portsmouth was the only public school district in Hampton Roads that spent $3,000 to honor a handful of students.
"They should find a way to honor the students where it does not cost the school system so much money," was the view of another taxpayer. Some taxpayers suggested using social media, which is free and arguably where young people are more likely to see it.
"Kids always talk about graduating on social media," said a Portsmouth taxpayer.
When asked why Portsmouth schools didn't use social media to honor its grads, school officials didn't have an answer.
Of the more than 1.1 billion people connecting on facebook today, Portsmouth Public Schools does not have a facebook page.

Modeling Water Intake Screens
Phil Kinnane | June 4, 2012
One of the interesting stories from this year's COMSOL News is the article concerning Johnson Screens®. They manufacture steel screens to block debris in water for pipes and valves. Their challenge is to design water intake screens with openings large enough for an unimpeded flow of water, but small enough to block enough debris depending on a specific application. This means that each screen must be custom-designed taking into account the characteristics of the debris and the depth at which the screen will be placed, as well as considering passing wildlife.
Using COMSOL Multiphysics, Johnson Screens took into account the fluid dynamics and structural mechanics of a particular screen. COMSOL Multiphysics is also used to model the impact of cyclical surges of water on the screens, called wave loading, as well as to model the cleaning of the water intake screens which is done by short bursts of air.

The Sound of a Fermi Gamma-ray Burst
We can't see gamma rays, but thanks to this reinterpretation of data from the Fermi Large Area Telescope, we can hear them. Gamma-ray bursts are incredibly powerful explosions, perhaps the most powerful in the universe.
This one originated from a deep-space explosion in 2008. Photons were divided into different instruments and frequencies and then slowed down big time so they could be separated to individual notes.
It's not exactly Beethoven, but it's a very special way to represent invisible data.

A former principal of Buckhannon-Upshur High School who jumped in a "dog pile" of students was rightfully suspended for her actions, West Virginia Supreme Court justices recently affirmed.
In their Jan. 12 memorandum decision, justices — except Justice Margaret L. Workman, who was disqualified —upheld a Kanawha County Circuit Court's order, which held that principal Brenda Wells violated West Virginia Board of Education policies.
The court also reversed the administrative law judge's reduction in Wells' suspension.
The incident stems from 2009 on the last day of class for seniors. Court documents state that a food fight broke out in the cafeteria.
When Wells heard the commotion, she came out of her office but when she got there, the food fight was over and students were congregating on the other side of the room.
Court documents state Wells went over to the group of students to make sure it wasn't a fight.
Court documents state a group of five to six male students were "piling on top of each other" and Wells jumped on a side of the pile for "no more than a couple of seconds."
"The students laughed at the action of grievant, (Wells), the male students broke up the pile and began separating," court documents state. "Students joked with grievant about her not being able to get her feet off the floor when she leaned on the pile."
Students took video of the dog pile by cell phone camera.
Wells said the reason she did this was to "diffuse the situation." However, the Upshur County Board of Education disagreed, saying her actions violated "safety, role model and the responsible citizen provisions of the employee code of conduct."
The Upshur County superintendent suspended Wells for five days without pay.
The issue was taken up by an administrative law judge, who found the board demonstrated that Wells' behavior deserved discipline but reduced the original five day unpaid suspension to one day.
Both parties took the issue before Kanawha County Circuit court. Wells argued the administrative law judge erred by saying the action warranted discipline, court documents state.
The board argued the reduction "exceeded the hearing examiner's statutory authority, was clearly wrong in view of the evidence, was arbitrary and capricious and characterized by a clearly unwarranted exercise of discretion."
However, Kanawha County Circuit Judge Paul Zakaib Jr. affirmed the decision by the West Virginia Public Employees Grievance Board, saying Wells was rightfully suspended for insubordination.
The court also, however, reversed the reduction in her suspension and reinstated her five-day unpaid suspension.

Topic Overview
Marijuana is a commonly abused drug. It is often called pot, grass, weed, reefer, Mary Jane, or buds. Marijuana cigarettes are commonly referred to as joints or spliffs, and the butt of a marijuana cigarette is called a roach. Marijuana can be eaten, brewed in tea, or smoked. In the United States, it is most often smoked in rolled joints, in pipes, or in hollowed-out cigars (blunts).
Immediate effects of marijuana depend on the strength and potency of its main active chemical, delta-9-tetrahydrocannabinol (THC).
Some people feel relaxed or high after smoking marijuana. Other people feel no change. The effects can be felt in seconds after inhaling and within 30 to 60 minutes after eating it. Effects last about 2 to 3 hours.
A person who has just had marijuana usually has dilated pupils and may have red, bloodshot eyes. He or she may behave differently, such as seeming to be dizzy and to have trouble walking or being silly and giggly for no reason. After smoking marijuana, some people may feel hungry (commonly referred to as having "the munchies") or sleepy. Sometimes people have negative effects from marijuana, such as sudden feelings of anxiety or paranoid thoughts.
Many people do not believe that using marijuana is a problem. But marijuana is not a "safe" drug. It causes physical and psychological problems. Marijuana use is harmful because:1
Frequent, heavy use of marijuana can lead to needing increasing amounts of it to get the same feelings (tolerance) and possibly to dependence (addiction). If daily use is stopped, flu-like withdrawal symptoms and craving for the drug can develop within 24 to 48 hours and last about 2 weeks.
Long-term, regular use of marijuana may contribute to developing some kinds of cancer, breathing problems similar to smoking (cough and wheezing), and a weakened immune system. Long-term heavy use can lead to reduced motivation and to difficulty maintaining attention to what's going on around you.
Marijuana is strongly absorbed by fatty tissues in various organs of the body. The chemical THC usually can be detected in urine several days after marijuana has been smoked. If marijuana is used heavily, traces of THC may be detected in urine for weeks after use has stopped.
Signs of use
Changes in a person's behavior that may indicate marijuana use include:
When a teen is using marijuana, the parent may find evidence of the drug and drug paraphernalia, including pipes and rolling papers, in the teen's bedroom. There may be a noticeable sweet odor on the teen's clothing. The teen may burn incense or use room deodorizers to get rid of the marijuana smell. The teen may also use eyedrops to get rid of bloodshot eyes.

The House is supposed to vote on the fiscal cliff deal that passed the Senate, however I'm not sure exactly when they will vote. In case they vote today I thought I'd start another open thread and leave you with the words of the Great One:
Some have been saying for weeks that Obama wants to go over the so-called fiscal cliff. But why would he when Republicans will vote to increase taxes $41 for every $1 in phony spending cuts? Obama gets his taxes, spending, and bloated federal government delivered to him by a bi-partisan gaggle of Democrat leftists and Republican cowards.
And yesterday Obama promised more of the same in 2013. He's all giddy now as he orchestrates the destruction of what's left of limited constitutional government and free market capitalism. And, of course, he's doing it all out of his selfless devotion to the middle class. He and he alone stands for we, the people. After all, he nearly received 51% of the vote, which to Obama means we apparently have no unalienable rights.
Marx and Alinsky would be proud of their pupil. The Founders would be in utter disbelief. We should be furious.

Perchloric acid is an inorganic compound with the formula HClO4. Usually found as an aqueous solution, this colorless compound is a stronger acid than sulfuric and nitric acids. It is a powerful oxidizer when hot, but its aqueous solutions up to approximately 70% and room temperature are generally safe, only showing strong acid features and no oxidizing properties. Perchloric acid is useful for preparing perchlorate salts, especially ammonium perchlorate, an important rocket fuel. Overall, perchloric acid is dangerously corrosive and readily forms potentially explosive mixtures.
Perchloric acid is produced industrially by two routes. The traditional method exploits the high aqueous solubility of sodium perchlorate (209 g/100 mL of water at room temperature). Treatment of such solutions with hydrochloric acid gives perchloric acid, precipitating solid sodium chloride:
- NaClO4 + HCl → NaCl + HClO4
The concentrated acid can be purified by distillation. The alternative route, which is more direct and avoids salts, entails anodic oxidation of aqueous chlorine at a platinum electrode.[5][6]
Laboratory preparations[edit]
Treatment of barium perchlorate with sulfuric acid precipitates barium sulfate, leaving perchloric acid. It also can be made by mixing nitric acid with ammonium perchlorate. The reaction gives nitrous oxide and perchloric acid due to a concurrent reaction involving the ammonium ion.
Anhydrous perchloric acid is an oily liquid at room temperature. It forms at least five hydrates, several of which have been characterized crystallographically. These solids consist of the perchlorate anion linked via hydrogen bonds to H2O and H3O+ centers[7] Perchloric acid forms an azeotrope with water, consisting of about 72.5% perchloric acid. This form of the acid is stable indefinitely and is commercially available. Such solutions are hygroscopic. Thus, if left open to the air, concentrated perchloric acid dilutes itself by absorbing water from the air.
Dehydration of perchloric acid gives the anhydride dichlorine heptoxide, which is even more dangerous:[8]
- 2 HClO4 + P4O10 → Cl2O7 + "H2P4O11"
Perchloric acid is mainly produced as a precursor to ammonium perchlorate, which is used as rocket fuel. The growth in rocketry has led to increased production of perchloric acid. Several million kilograms are produced annually.[5] Perchloric acid is one of the most proven materials for etching of liquid crystal displays and critical electronics applications as well as ore extraction and has unique properties in analytical chemistry.[9] Additionally it is a useful component in etching of chrome[10]
Its use in analytical chemistry was championed in the U.S. by George Frederick Smith under the tutelage of H.H. Willard, for its unique properties. He used perchloric acid to produce magnesium perchlorate in his garage for the steel industry and later established a company, G. Frederick Smith Chemical Co, to produce additional perchlorate salts.
As an acid[edit]
Perchloric acid, a superacid, is one of the strongest Brønsted-Lowry acids. Its pKa is −10.[11] It provides strong acidity with minimal interference because perchlorate is weakly nucleophilic (explaining the high acidity of HClO4). Other acids of noncoordinating anions, such as fluoroboric acid and hexafluorophosphoric acid are susceptible to hydrolysis, whereas perchloric acid is not. Despite hazards associated with the explosiveness of its salts, the acid is often preferred in certain syntheses.[12] For similar reasons, it is a useful eluent in ion-exchange chromatography.
It is also used for electropolishing/etching of aluminum, molybdenum, and other metals.
Given its strong oxidizing properties, perchloric acid is subject to extensive regulations.[13] It is highly reactive with metals (e.g., aluminium) and organic matter (wood, plastics). On February 20, 1947, in Los Angeles California, 17 people were killed and 150 injured when a bath, consisting of over 1000 litres of 75% perchloric acid and 25% acetic anhydride by volume, exploded. The plant, 25 other buildings and 40 automobiles were obliterated and 250 nearby homes were damaged. The bath was being used to electro-polish aluminum furniture. In addition, organic compounds were added to the overheating bath when an iron rack was replaced with one coated with cellulose acetobutyrate (Tenit-2 plastic). A few minutes later the bath exploded.[14][15]
Work conducted with perchloric acid must be conducted in fume hoods with a wash-down capability to prevent accumulation of oxidisers in the ductwork.

We recently had the opportunity to sample some new menu items at BD's Mongolian Grill in Royal Oak. BD's is a fairly well known chain that specializes in build your own stir fry.
Since 1992, BD's has been offering is unique dining experience.
Like any restaurant trying to appeal to more people, the addition of menu items is a necessity. "Sometimes people don't want stir fry," says senior marketing manager Brad Russell, "we want to bring in the veto vote." The veto vote is the one person in the office who doesn't want stir fry.
Now, there are more options at Mongolian Grill. From burgers to lettuce wraps to Buffalo chicken nachos (by TheHungryDudes), BD's has diversified its menu considerably.
