  • How can a large, Fortran-based number crunching codebase be modernized?

    - by Dave Mateer
    A friend in academia asked me for advice (I'm a C# business application developer). He has a legacy codebase which he wrote in Fortran in the medical imaging field. It does a huge amount of number crunching using vectors. He uses a cluster (30ish cores) and has now gone towards a single workstation with 500ish GPUS in it. However where to go next with the codebase so: Other people can maintain it over next 10 year cycle Get faster at tweaking the software Can run on different infrastructures without recompiles After some research from me (this is a super interesting area) some options are: Use Python and CUDA from Nvidia Rewrite in a functional language. For example, F# or Haskell Go cloud based and use something like Hadoop and Java Learn C What has been your experience with this? What should my friend be looking at to modernize his codebase? UPDATE: Thanks @Mark and everyone who has answered. The reasons my friend is asking this question is that it's a perfect time in the projects lifecycle to do a review. Bringing research assistants up to speed in Fortran takes time (I like C#, and especially the tooling and can't imagine going back to older languages!!) I liked the suggestion of keeping the pure number crunching in Fortran, but wrapping it in something newer. Perhaps Python as that seems to be getting a stronghold in academia as a general-purpose programming language that is fairly easy to pick up. See Medical Imaging and a guy who has written a Fortran wrapper for CUDA, Can I legally publish my Fortran 90 wrappers to Nvidias' CUFFT library (from the CUDA SDK)?.

  • Our winners- and some BBQ for everyone

    - by Steve Tunstall
    Congrats to our two winners for the first two comments on my last entry. Steve from Australia and John Lemon. Steve won since he was the first person over the International Date Line to see the post I made so late after a workday on Friday. So not only does he get to live in a country with the 2nd most beautiful women in the world, but now he gets some cool Oracle Swag, too. (Yes, I live on the beach in southern California, so you can guess where 1st place is for that other contest…Now if Steve happens to live in Manly, we may actually have a tie going…) OK, ok, for everyone else, you can be winners, too. How you ask? I will make you the envy of every guy and gal in your neighborhood or campsite. What follows is the way to smoke the best ribs you or anyone you know have ever tasted. Follow my instructions and give it a try. People at your party/cookout/campsite will tell you that they’re the best ribs they’ve ever had, and I will let you take all the credit. Yes, I fully realize this post is going to be longer than any post I’ve done yet. But let’s get serious here. Smoking meat is much more important, agreed? J In all honesty, this is a repeat of another blog I did, so I’m just copying and pasting. Step 1. Get some ribs. I actually really like Costco’s pack. They have both St. Louis and Baby Back. (They are the same ribs, but cut in half down the sides. St. Louis style is the ‘front’ of the ribs closest to the stomach, and ‘Baby back’ is the part of the ribs where is connects to the backbone). I like them both, so here you see I got one pack of each. About 4 racks to a pack. So these two packs for $25 each will feed about 16-20 of my guests. So around 3 bucks a person is a pretty good deal for the best ribs you’ll ever have. Step 2. Prep the ribs the night before you’re going to smoke. You need to trim them to fit your smoker racks, and also take off the membrane and add your rub. Then cover and set in fridge overnight. Here’s how to take off the membrane, which will not break down with heat and smoke like the rest of the meat, so must be removed. Use a butter knife to work in a ways between the membrane and the white bone. Just enough to make room for your finger. Try really hard not to poke through the membrane, you want to keep it whole. See how my gloved fingers can now start to lift up and pull off the membrane? This is what you are trying to do. It’s awesome when the whole thing can come off at once. This one is going great, maybe the best one I’ve ever done. Sometime, it falls apart and doesn't come off in one nice piece. I hate when that happens. Now, add your rub and pat it down once into the meat with your other hand. My rub is not secret. I got it from my mentor, a BBQ competitive chef who is currently ranked #1 in California and #3 in the nation on the BBQ circuit. He does full-day classes in southern California if anyone is interested in taking his class. Go to www.slapyodaddybbq.com to check him out. I tweaked his run recipe a tad and made my own. It’s one part Lawry’s, one part sugar, one part Montreal Steak Seasoning, one part garlic powder, one-half part red chili powder, one-half part paprika, and then 1/20th part cayenne. You can adjust that last ingredient, or leave it out. Real cheap stuff you can get at Costco. This lets you make enough rub to last about a year or two. Don’t make it all at once, make a shaker’s worth and use it up before you make more. Place it all in a bowl, mix well, and then add to a shaker like you see here. You can get a shaker with medium sized holes on it at any restaurant supply store or Smart & Final. The kind you see at pizza places for their red pepper flakes works best. Now cover and place in fridge overnight. Step 3. The next day. Ok, I’m ready to go. Get your stuff together. You will need your smoker, some good foil, a can of peach nectar, a bottle of Agave syrup, and a package of brown sugar. You will need this stuff later. I also use a clean spray bottle, and apple juice. Step 4. Make your fire, or turn on your electric smoker. In this example I’m using my portable charcoal smoker. I got this for only $40. I then modified it to be useful. Once modified, these guys actually work very well. Trust me, your food DOES NOT KNOW how expensive your smoker is. Someone who tells you that you need to spend a bunch of money on a smoker is an idiot. I also have an electric smoker that stays in my backyard. It’s cleaner and larger so I can smoke more food. But this little $40 one works great for going camping. Here is what my fire-bowl looks like. I leave a space in the middle open, and place cold charcoal and wood chucks in a circle going outwards. This makes it so when I dump the hot coals down the middle, they will slowly burn outwards, hitting different wood chucks at different times, allowing me to go 4-5 hours without having to even touch my fire. For ribs, I use apple and pecan wood. Pecan works for anything. Apple or any fruit wood is excellent for pork. So now I make my hot charcoal with a chimney only about half-full. I found a great use for that side-burner on my grill that I never use. It makes a fantastic chimney starter. You never use fluids of any kind, nor ever use that stupid charcoal that has lighter fluid built into it. Never, ever, ever. Step 5. Smoke. Add your ribs in the racks and stack them up in your smoker. I have a digital thermometer on a probe that I use to keep track of the temp in the smoker. I just lay the probe on the top rack and shut the lid. This cheap guy is a little harder to maintain the right temperature of around 225 F, so I do have to keep my eye on it more than my electric one or a more expensive charcoal one with the cool gadgets that regulate your temp for you. Every hour, spray apple juice all over your ribs using that spray bottle. After about 3 hours, you should have a very good crust (called the Bark) on your ribs. Once you have the Bark where you want it, carefully remove your ribs and place them in a tray. We are now ready for a very important part to make the flavor. Get a large piece of foil and place one rib section on it. Splash some of the peach nectar on it, and then a drizzle of the Agave syrup. Then, use your gloved hand to pack on some brown sugar. Do this on BOTH sides, and then completely wrap it up TIGHT in the foil. Do this for each rib section, and then place all the wrapped sections back into the smoker for another 4 to 6 hours. This is where the meat will get tender and flavorful. The first three hours is only to make the smoke bark. You don’t need smoke anymore, since the ribs are wrapped, you only need to keep the heat around 225 for the next 4-6 hours. Obviously you don’t spray anymore. Just time and slow heat. Be patient. It’s actually really hard to overdo it. You can let them go longer, and all that will happen is they will get even MORE tender!!! If you take them out too soon, they will be tough. How do you know? Take out one package (use long tongs) and open it up. If you grab a bone with your tongs and it just falls apart and breaks away from the rest of the meat, you are done!!! Enjoy!!! Step 6. Eat. It pulls apart like this when it’s done. By the way, smoking tri-tip is way easier. Just rub it with the same rub, and put in your smoker for about 2.5 hours at 250 F. That’s it. Low-maintenance. It comes out like this, with a fantastic smoke ring and amazing flavor. Thanks, and I will put up another good tip, about the ZFSSA, around the end of November. Steve

  • DIY Homemade Hybrid Rocket Engine [Video]

    - by Jason Fitzpatrick
    Remember the guy with the cool DIY astronaut ice cream build? He’s back with a mini hybrid rocket engine that runs off oxygen and acrylic. I built a small rocket engine for demonstration purposes. The engine is built from a 2″ diameter acrylic rod through which I drilled a 0.5″ hole. The oxygen at 80 psi or less is passed through the hole and then is forced through a convergent-divergent nozzle at the tail end. The nozzle’s throat is about 0.25″ and expands to 0.625″. I lit the engine by inserting a burning cotton swab (with wooden stick) while a small amount of oxygen was flowing. The acrylic catches fire very easily in a pure oxygen environment. The engine can be throttled and shut off completely, which is a major benefit to hybrid engine designs. Solid-fuel rockets cannot be throttled or shut off, which makes them difficult to control.

  • What is an elegant way to install non-repository software in 12.04?

    - by Tomas
    Perhaps I missed something when Canonical removed the "Create launcher" option from the right click menu, because I've really been missing that little guy. For me, it was the preferred way to install software that comes not in a .deb, but in a tar.gz, for example. (Note: in that tar.gz I have a folder with the compiled files, I'm NOT compiling from source) I just downloaded the new Eclipse IDE and extracted the tar.gz to my /usr folder. Now, I'd like to add it to my desktop and dash so it can be started easily. Intuitively I would right click the desktop and create a launcher. After this I'd copy the .desktop to /usr/share/applications. However, creating a launcher is not possible. My question: How would you install an already compiled tar.gz that you have downloaded from the internet? Below are a few things I've seen, but these are all more time-consuming than the right click option. If you have any better ideas, please let me know. Thanks! Manual copy & create a .desktop file: manually Simply extract the archive to /usr. Create a new text file, adding something along the lines of the code block below: [Desktop Entry] Version=1.0 Type=Application Terminal=false Exec="/usr/local/eclipse42/eclipse" Name="Eclipse 4.2" Icon=/home/tomas/icons/eclipse.svg Rename this file to eclipse42.desktop and make it executable. Then copy this to /usr/share/applications. Manually copy & create a .desktop file: GUI fossfreedom has elaborated on this in How can I create launchers on my desktop? Basically it involves the command: gnome-desktop-item-edit --create-new ~/Desktop After creating the launcher, copy it to /usr/share/applications.

  • A few unpleasant facts about Visual Studio 2012.

    - by Ilya Verbitskiy
    I have been playing with Visual Studio 2012 for the last couple of days. New IDE is pretty good, but, unfortunately, I found a few unpleasant facts. First of all, new release is coming without Visual Studio setup projects. I am disappointed, because I am using it for my pet project – Easy Shutdown. The tool is a small widget-like application which allows you to reboot, log out or shut down you PC. I have not done any decision yet, but I would probably migrate to WiX. The second surprise is Microsoft will not add Visual Studio macros to the next release. Since I am lazy guy, I like small hacks using macros. For example I have macros to refresh all projects or attach to IIS.  The only way how to solve the problem is to convert your macros to Visual Studio plugin. I have not tried it yet, but I will definitely do in the nearest future. The third fact, I do not like, is Visual Studio default themes. May be somebody like it, but they are hard to adopt after Visual Studio 2010. Fortunately there is a solution. Matthew Johnson released Visual Studio 2012 Color Theme Editor. It comes with a few predefined themes. I really like the Blue one.

  • My boss is feuding with his boss. My workload is expanding What should I do?

    - by steve
    These two have always had a somewhat shaky relationship when they were on the same level. The other guy was recently promoted to director and now my boss reports to him. On the surface, they appear to get along when they get together, but my boss despises the man and badmouths him every chance that he gets (to peers, subordinates, etc). He believe that the director is setting him up to fail. The Director and upper management is holding my boss responsible for the not-so-great performance by the team as of late. He's been playing games to make my boss look bad. Due to lay offs, we don't have the manpower to deliever the results that we did before...but expectations have not lowered...and my boss is taking the heat for it. Now he's on the warpath and starting to micromanage. He's giving everyone more work. He's forcing us midlevel guys to take responsibility for the level one techs' performance. I'm spending less and less time coding....and more time babysitting vendors, techs, etc. I'm not so sure that's a bad thing because I'm sorta burnt out on coding, but I don't really care for the idea of having to be responsible for others poor performance....isn't that the manager's job? Anyway, do you guys have any suggestions on dealing with the situation?

  • Why do programmers write applications and then make them free?

    - by Ken
    As an entrepreneur/programmer who makes a good living from writing and selling software, I'm dumbfounded as to why developers write applications and then put them up on the Internet for free. You've found yourself in one of the most lucrative fields in the world. A business with 99% profit margin, where you have no physical product but can name your price; a business where you can ship a buggy product and the customer will still buy it. Occasionally some of our software will get a free competitor, and I think, this guy is crazy. He could be making a good living off of this but instead chose to make it free. Do you not like giant piles of money? Are you not confident that people would pay for it? Are you afraid of having to support it? It's bad for the business of programming because now customers expect to be able to find a free solution to every problem. (I see tweets like "is there any good FREE software for XYZ? or do I need to pay $20 for that".) It's also bad for customers because the free solutions eventually break (because of a new OS or what have you) and since it's free, the developer has no reason to fix it. Customers end up with free but stale software that no longer works and never gets updated. Customer cries. Developer still working day job cries in their cubical. What gives? PS: I'm not looking to start an open-source/software should be free kind of debate. I'm talking about when developers make a closed source application and make it free.

  • Edd strikes again &ndash; IronRuby for Rubyists on InfoQ

    - by Eric Nelson
    Colleague, friend and generally top guy on IronRuby Edd Morgan has just been published over on InfoQ. To wet the appetite… a snippet or three. IronRuby for Rubyists IronRuby is Microsoft's implementation of the Ruby language we all know and love with the added bonus of interoperability with the .NET framework — the Iron in the name is actually an acronym for 'Implementation running on .NET'. It's supported by the .NET Common Language Runtime as well as, albeit unofficially, the Mono project. You'd be forgiven for harbouring some question in your mind about running a dynamic language such as Ruby atop the CLR - that's where the DLR (Dynamic Language Runtime) comes in. The DLR is Microsoft's way of providing dynamic language capability on top of the CLR. Both IronRuby and the DLR are, as part of Microsoft's commitment to open source software, available as part of the Microsoft Public License on GitHub and CodePlex respectively… And Metaprogramming with IronRuby The art and science of metaprogramming — especially in Ruby, where it's an absolute joy — is something that could very easily span an entire article. As you would hope, IronRuby code is fully able to manipulate itself allowing you to bend your classes to your whim just as you would expect with a good dynamic language… And Riding the irails? So let's get to the point. I think it's a solid bet to make that a large proportion of Ruby programmers are familiar with the Rails framework - perhaps it's even safe to assume that most were first led to the Ruby language by the siren song of the Rails framework itself. Long story short, IronRuby is compatible enough to run your Rails app… Now… get yourself over to the full article and also check out some of Edds other work below.

  • .NET development on Macs

    - by Jeff
    I posted the “exciting” conclusion of my laptop trade-ins and issues on my personal blog. The links, in chronological order, are posted below. While those posts have all of the details about performance and software used, I wanted to comment on why I like using Macs in the first place. It started in 2006 when Apple released the first Intel-based Mac. As someone with a professional video past, I had been using Macs on and off since college (1995 graduate), so I was never terribly religious about any particular platform. I’m still not, but until recently, it was staggering how crappy PC’s were. They were all plastic, disposable, commodity crap. I could never justify buying a PowerBook because I was a Microsoft stack guy. When Apple went Intel, they removed that barrier. They also didn’t screw around with selling to the low end (though the plastic MacBooks bordered on that), so even the base machines were pretty well equipped. Every Mac I’ve had, I’ve used for three years. Other than that first one, I’ve also sold each one, for quite a bit of money. Things have changed quite a bit, mostly within the last year. I’m actually relieved, because Apple needs competition at the high end. Other manufacturers are finally understanding the importance of industrial design. For me, I’ll stick with Macs for now, because I’m invested in OS X apps like Aperture and the Mac versions of Adobe products. As a Microsoft developer, it doesn’t even matter though… with Parallels, I Cmd-Tab and I’m in Windows. So after three and a half years with a wonderful 17” MBP and upgraded SSD, it was time to get something lighter and smaller (traveling light is critical with a toddler), and I eventually ended up with a 13” MacBook Air, with the i7 and 8 gig upgrades, and I love it. At home I “dock” it to a Thunderbolt Display.

  • How do I install Red5 using apt-get? Getting sub-process error

    - by Dalen
    This is copy from question of some guy on other forum that never got satisfiably answered. I encountered the same error few days ago on Ubuntu 13.04 Desktop. It seems like Red5 is installed but it cannot be run for some reason. Can anyone explain what is going on here? Why should dpkg fail?

  • How not to suffer from ideologists when you're a pragmatic person?

    - by Lukas Eder
    My story: I'm a pragmatic person. Sometimes, the most simple solution to a problem to get the job done is the one that fits best for me, if its not an utter blasphemy and reproach to any design principles. Check out my answer to this question on stackoverflow. Simple. Works. Was accepted. Could be improved. Is clearly not perfect. And along comes this guy. He downvotes me, comments on the question how his answer is better, more accurate etc and calls me "plain wrong". Reminds me of this comic strip. :-) While on stackoverflow I can laugh at these things because those people are far away, in the real world I'm suffering from ideologies every now and then. Heck, I'm not creating a miracle piece of software, I need to keep that huge legacy thing running, and it's an adventure to me every day. I don't have the time or passion to beautify my code (or other people's code) to that extent. My question(s): How do you deal with ideologies / ideologists, when you're a pragmatic person? How do you deal with pragmatism / pragmatists, when you're an ideologic person? I'm interested in both point of views. Tell me your experience. But please, be fair, somewhat objective, and understand that you may NOT be entirely correct and your opinion is NOT the only true one... :-)

  • How to explain a layperson why a developer should not be interrupted while neck-deep in coding?

    - by András Szepesházi
    If you just consider the second part of my question, "Why a developer should not be interrupted while neck-deep in coding", that has been discussed a number of times by smart people. Heck, even the co-founder of SO, Joel Spolsky, wrote a blog post about "getting in the zone" and "being knocked out of the zone" and why it takes an average of 15 minutes to achieve productivity when participating in complex, software development related tasks. So I think the why has been established. What I'm interested in is how to explain all that to somebody who doesn't know beans about Beans (khmm I mean software development). How to tell the wife, or the funny guy from accounting at the workplace, or the long time friend who pings you on Skype every 30 minutes with a "Wazzzzzzup?!", that all the interruptions have a much deeper impact on your work than the obvious 30 seconds they took from your time. Obviously you can't explain it by sentences like "I have to juggle a lot of variable names in my short term memory" unless you want to be the target of blank stares or friendly abuse. I'd like to be able to explain all that to non-developers in a way that will make them clearly understand - without being offensive, elitist or too technical.

  • Is what someone publishes on the Internet fair game when considering them for employment as a programmer?

    - by Jon Hopkins
    (Originally posted on Stack Overflow but closed there and more relevant for here) So we first interviewed a guy for a technical role and he was pretty good. Before the second interview we googled him and found his MySpace page which could, to put it mildly, be regarded as inappropriate. Just to be clear there was no doubt that it was his page (name, photos, matching biographical information and so on). The content was entirely personal and in no way related to his professional abilities or attitude. Is it fair to consider this when thinking about whether to offer them a job? In most situations my response would be what goes on in someone's private life is their own doing. However for anyone technical who professes (implicitly or explicitly) to understand the Internet and the possibilities it offers, is posting things in a way which can so obviously be discovered a significant error of judgement? EDIT: Clarification - essentially it was a fairly graphic commentary on porn (but of, shall we say, a non-academic nature). I'm actually more interested in the general concept than the specific incident as it's something we're likely to see more in the future as people put more and more of themselves on-line. My concerns are not primarily about him and how he feels about such things (he's white, straight, male and about the last possible victim of discrimination on the planet in that sense), more how it reflects on the company that a very simple search (basically his name) returns these things and that clients may also do it. We work in a relatively conservative industry.

  • Self Service Reporting With PowerPivot

    - by blakmk
    There are so many cool new features in Sql 2008 release 2 it was difficult for me to pick a topic for T-SQL Tuesday . But the one that I am now a secret fan of, I once resented for its creation. Let me explain, for years I have encountered reporting systems cobbled together in tools like Access and Excel built by "database hobbyists" who had no formal training in database design or best practices. They would take their monstrosities as far as they could go before ultimatley it stopped working or the person that wrote it left the company. At that point it would become the resident DBA's problem to support it as a Live application. So when I first heard of Power Pivot, a sense of Deja Vu overtook me and I felt like the guy in the Ausin Powers movie , knowing the inevitable is coming but somehow unsure how to get out of the way. But when I eventually saw it in action, I quickly realised that it is a very powerful tool. It has a much smaller "time to market" than traditional BI architectures. Combined with the new features of Excel, some pretty impressive dashboards can be produced.Of course PowerPivot is not a magic bullet and along with potential scalability issues there are the usual issues such as master data management and data quality that cannot be overcome easily with power pivot. As a tool though, it has potential. Traditional BI is expensive, both in terms of time and the amount of resources it takes to deliver the system. The time lag between an analyst or a commercial accountant requesting reports and the report being delivered can make a huge commercial difference. I have observed companies where empowered end users become extremely productive when allowed to plough in to various disperate datasets. It may not be the correct way or the most sustainable but its cheap and quick. In these times when budgets are being slashed and we are forced to deliver more with less, why not empower the end user in a tool that is designed for exactly this task.... @blakmk

  • Duplication of code (backend and javascript - knockout)

    - by Michal B.
    We have a new developer in our team. He seems a smart guy (he just came in so I cannot really judge). He started with implementing some small enhancements in the project (MVC3 web application using javascript - jquery and knockout). Let's say we have two values: A - quite complex calculation C - constant B = A + C On the screen there is value B and user can change it (normal texbox). When B changes, A changes as well because C is constant. So there is linear dependency between A and B. Now, all the calculations are done in the backend, but we need to recalculate A as user changes B (in js, I would use knockout). I thought about storing old A and B and when B changes by 10 then we know that new A will be old A + 10. He says this is dirty, because it's duplication of code (we make use of the fact that they are dependent and according to him that should be only in one place in our app). I understand it's not ideal, but making AJAX request after every key press seems a bit too much. It's a really small thing and I would not post if we haven't had long discussion about it. How do you deal with such problems? Also I can imagine that using knockout implies lots of calculations on the client side, which very often leads to duplication of the same calculations from the backend. Does anyone have links to some articles/thoughts on this topic?

  • Dealing with an Idiot [closed]

    - by inspectorG4dget
    I'm a 4th year University Computer Science student, and I have this problem, that I don't seem to be able to find a straight answer to: As a 4th year computer science student, I spend more time in the computer lab on campus, than even my own home. This means that getting along with everyone else here is very important to me. In most cases, this is not an issue because my interactions with almost all the people here fall into one of the following categories: Let me help you, junior Hi fellow student in a course I'm taking, I'm having trouble with this assignment question. Can you give me a hint as to how you solved it? Hi fellow student in a course I'm taking, This is how I solved the problem that you're stuck on. Hope it helps Hi fellow student, I noticed that you're working on a project, using a library that I'm interested in. Can we setup a time so I can learn about this library from you? This model of interaction works very well for me. However, there is one fellow student, who manages to make my life hell beyond all of this (his name is not important, let's just call him "Sam"). He seems to be always (pardon my crass description) high and completely unwilling to contribute to a constructive, academic conversation. He's a pretty smart guy, but just comes across as (I hate to say something like this about a fellow student, but) an imbecile. He also has ignorant opinions on important topics, some of which pertain to my specialization (AI, NLP, etc), and when I try to explain to him why he's wrong, all he does is insult me and put me in a foul mood. I have tried ignoring him (sitting somewhere else in the lab, headphones, etc), but he seems to like doing this because he approaches me and no amount of "leave me alone" seems to do the trick. Can anyone please suggest to me how to deal with this man in a civil way? Thank you

  • Working with fubar/refuctored code

    - by Keyo
    I'm working with some code which was written by a contractor who left a year ago leaving a number of projects with buggy, disgustingly bad code. This is what I call cowboy PHP, say no more. Ideally I'd like to leave the project as is and never touch it again. Things break, requirements change and it needs to be maintained. Part A needs to be changed. There is a bug I cannot reproduce. Part A is connect to parts B D and E. This kind of work gives me a headache and makes me die a little inside. It kills my motivation and productivity. To be honest I'd say it's affecting my mental health. Perhaps being at the start of my career I'm being naive to think production code should be reasonably clean. I would like to hear from anyone else who has been in this situation before. What did you do to get out of it? I'm thinking long term I might have to find another job. Edit I've moved on from this company now, to a place where idiots are not employed. The code isn't perfect but it's at least manageable and peer reviewed. There are a lot of people in the comments below telling me that software is messy like this. Sure I don't agree with the way some programmers do things but this code was seriously mangled. The guy who wrote it tried to reinvent every wheel he could, and badly. He stopped getting work from us because of his bad code that nobody on the team could stand. If it were easy to refactor I would have. Eventually after many 'just do this small 10minute change' situations had ballooned into hours of lost time (regardless of who on the team was doing the work) my boss finally caved in it was rewritten.

  • Can non-IT people handle a wiki?

    - by Andrew Heath
    (I'm hoping that some of you will have encountered this issue before and can offer some insights...) My company is looking to improve their market research data management. Current data management style: "Hey Jimbo, where's that picture of our WhatZit 2.0? "yeah I remember that email about that company from that guy, gimme a few minutes to search my Outlook" "who has the newest copy of the Important Competitor's product catalogue? Mine is from '09." ... "Colleen does, and she's on maternity leave. You'll have to call her to get her workstation password..." Desired data management style: data organized neatly by topic (legal, economic, industrial, competitor) for each topic, multiple media types stored together (company product images, press releases, contact info) but still neatly sorted by type data editing histories communal access (no data silos) I was thinking about setting up a department wiki for all users to access. It seems to satisfy the four criteria above, but I'm a little concerned about how user-friendly (read: decipherable to non-technical people) it is for the more advanced features like image galleries, article formatting, and the like. Has anyone here setup a wiki for non-IT people and had it not catch on fire//become a ghost town//look like Geocities? Bonus question: can you see any obvious drawbacks to my choice of MediaWiki (or any other wiki) for solving this problem? Thank you.

  • Problems with Maverick upgrade

    - by altenuta
    I upgraded to Maverick 10.10 from Lucid. I have an old Toshiba Satellite with a 1.1 MHz and 256MB RAM. Initially I couldn't get my wireless to work. That solved itself after installing various updates and programs. The problems that remain are: I have to authorize at least 2 times at start-up. This machine is Ubuntu only. No boot load screen. I have a ton of programs and system directories that are in my home folder. Is this normal? It is difficult to wake the computer from sleep. Usually I just shut it down and restart. Tonight I waited and got a message about corrupt memory. The computer takes forever to do just about everything. Slow to start programs or doing things on the web. I am a longtime Mac user (since 1986). I also manage a network of several windoze machines. I am definitely a GUI guy and do very little in the terminal so I really need to know where to begin to get things straightened out. Can I rescue this machine without wiping it and doing a fresh install? This is basically a hobby machine. Aside from all the programs and upgrades I've installed, I have almost no files or documents to worry about saving. Anyone have any ideas about the problems I'm having and the best way to proceed? Thanks, Al

  • How to explain a layperson why a developer should not be interrupted while neck-deep in coding?

    - by András Szepesházi
    If you just consider the second part of my question, "Why a developer should not be interrupted while neck-deep in coding", that has been discussed a number of times by smart people. Heck, even the co-founder of SO, Joel Spolsky, wrote a blog post about "getting in the zone" and "being knocked out of the zone" and why it takes an average of 15 minutes to achieve productivity when participating in complex, software development related tasks. So I think the why has been established. What I'm interested in is how to explain all that to somebody who doesn't know beans about Beans (khmm I mean software development). How to tell the wife, or the funny guy from accounting at the workplace, or the long time friend who pings you on Skype every 30 minutes with a "Wazzzzzzup?!", that all the interruptions have a much deeper impact on your work than the obvious 30 seconds they took from your time. Obviously you can't explain it by sentences like "I have to juggle a lot of variable names in my short term memory" unless you want to be the target of blank stares or friendly abuse. I'd like to be able to explain all that to non-developers in a way that will make them clearly understand - without being offensive, elitist or too technical. EDIT: Thanks to everyone for their great insights. I've accepted EpsilonVector's answer as his analogy was the closest one to my original needs. The "falling asleep" explanation is neither offensive nor technical, almost anyone can relate to it, and the consequences of getting disturbed while falling asleep or while being in the zone are very similar: you experience frustration and you "lose" 15-20 minutes of time.

  • Removed Java replaced with newest "Sun Java", disc won't boot, and won't let me re-install grub using boot repair disc

    - by Al Rowe
    Had a minor problem with my Stock market platform. Set-up screen would freeze program. Called their tech support, got their "Linux guy", who advised remove all Java and replace, not with synaptic version, but newest Sun Java. After removing, computer auto rebooted, and went to blue mem-test screen. Showed no errors, but couldn't get back in. Tried two versions of boot repair disc from iso (checked md5sum, showed good.), but fix aborted, giving apt-error detected. Opened a terminal and typed (or copy/paste): sudo chroot "/mnt/boot-sav/sda1" apt-get -f install. My system is Ubuntu 12.04. Had a few very minor issues from install, all fixed. Also added some of my favorite gnome tricks just to make life easier, but none that could have caused this. Added script to add shortcuts to desktop, open terminal in any menu from inside it, access root terminal, etc. System was firewalled and using avast antivirus (o.k., I'm paranoid. Used to do Windows sys-op and security.) But relative newbie to Linux.

  • Should I expect my team to have more than a basic proficiency with our source control system?

    - by Joshua Smith
    My company switched from Subversion to Git about three months ago. We had weeks of advance notice prior to the switch. Since I'd never used Git before (or any other DVCS), I read Pro Git and spent a little time spinning up my own repositories and playing around, so that when we switched I'd be able to keep working with minimal pain. Now I'm the 'Git guy' by default. With a couple of exceptions, most of my team still has no idea how Git works. For example, they still think of branches as complete copies of the source code, and even go so far as to clone the repo into multiple folders (one per branch). They generally look at Git as a scary black box. Given the fundamental nature of source control in our daily work (not to mention the ridiculous amount of power Git affords us), I'm of the opinion that any dev who doesn't achieve a certain level of proficiency with it is a liability. Should I expect my team to have at least some understanding of how Git works internally, and how to use it beyond the most basic pull/merge/push operations? Or am I just making something out of nothing?
