  • Bash: Reset and Clear Commands

    - by sixtyfootersdude
    I have been using the command: reset to clear my terminal. Although I am pretty sure this is not what I should be doing. Reset, as the name suggests resets your entire terminal (changes lots of stuff). Here is what I want: I basically want to use the command clear. However if you clear and then scowl up you still get tones of stuff from before. In general this is not a problem however I am looking at gross logs that are long and I want to make sure that I am just viewing the most recent one. I know that I could use more or something like that but I prefer this approach.

  • XSLT is not the solution you're looking for

    - by Jeff
    I was very relieved to see that Umbraco is ditching XSLT as a rendering mechanism in the forthcoming v5. Thank God for that. After working in this business for a very long time, I can't think of any other technology that has been inappropriately used, time after time, and without any compelling reason.The place I remember seeing it the most was during my time at Insurance.com. We used it, mostly, for two reasons. The first and justifiable reason was that it tweaked data for messaging to the various insurance carriers. While they all shared a "standard" for insurance quoting, they all had their little nuances we had to accommodate, so XSLT made sense. The other thing we used it for was rendering in the interview app. In other words, when we showed you some fancy UI, we'd often ditch the control rendering and straight HTML and use XSLT. I hated it.There just hasn't been a technology hammer that made every problem look like a nail (or however that metaphor goes) the way XSLT has. Imagine my horror the first week at Microsoft, when my team assumed control of the MSDN/TechNet forums, and we saw a mess of XSLT for some parts of it. I don't have to tell you that we ripped that stuff out pretty quickly. I can't even tell you how many performance problems went away as we started to rip it out.XSLT is not your friend. It has a place in the world, but that place is tweaking XML, not rendering UI.

  • Is Joel Test really a good gauging tool?

    - by henry
    I just learned about Joel Test. I have been computer programmer for 22 years, but somehow never heard about it before. I consider my best job so far to be this small investment managing company with 30 employees and only 3 people in IT department. I am no longer with them but I had being working there for 5 years – my longest streak with any given company. To my surprise they scored extremely poor on Joel Test. The only two questions I would answer “yes” are #4: Do you have a bug database? And #9: Do you use the best tools money can buy? Everything else is either “sometimes” or straight “no”. Here is what I liked about the company however: a) Good pay, they bragged about it to my face and I bragged about it to their face, so it was almost like a family environment. b) I always knew big picture. When writing a code to solve particular problem there were no ambiguity about the business nature of that problem. Even though we did not always had written specs we could ask business users a question anytime, often yelling it across the floor. I could even talk to executives any time I felt like doing it: no appointment necessary. c) Immediate feedback. Once we implement a solution and make business users happy they immediately let us know that, we (programmers) become heroes of the moment. d) No red tape. I could always buy any tools I deem necessary, and design solutions the way my professional judgment dictates. e) Flexibility. If I had mid-day dental appointment that is near my house rather than near the office, I would send email to the company: "FYI: I work from home today". As long as one of 3 IT guys was on the floor (to help traders in case their monitors go dark) they did not care where 2 others are. So the question thus becomes how valuable Joel Test is? Why bother with it?

  • Asus Eee PC 1000HE wireless woes

    - by Vladimir Noobokov
    Ever since I have upgraded my Asus Eee PC 1000HE from Lucid 10.04 to Precise 12.04 I have been having issues with my wireless connections. At first I had wireless dropouts: I would be able to start using wireless, but then after a few minutes the wireless would stop working even though I was still connected to the network. Lately things turned worse: while I connect to my wireless network, it just never works. I tried all sorts of solutions on offer here and in other forums but none worked. At best I got the wireless to work up until I rebooted, at which point I would get the same symptoms again: the wireless network is there, but it's not really working. By now I tried so many different "solutions" I don't know where to start describing them; I have also reinstalled 12.04 several times, enough to make me lose faith in Ubuntu. Help here looks like my last resort. For the record, my Asus Eee PC 1000HE is equipped with an Atheros wireless card. I have reinstalled 12.04, ran all the suggested updates, and receive the following response when I type iwconfig in the terminal: lo no wireless extensions. wlan0 IEEE 802.11bgn ESSID:"Arsenal" Mode:Managed Frequency:2.452 GHz Access Point: 00:04:ED:48:67:89 Bit Rate=1 Mb/s Tx-Power=16 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=70/70 Signal level=-29 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:27 Invalid misc:57 Missed beacon:0 eth0 no wireless extensions.

  • CERN Announces the Discovery of a Higgs-Boson-like Particle

    - by Jason Fitzpatrick
    CERN scientists dropped a press release today indicating they’ve found a particle consistent with the long sought after Higgs Boson particle–the “God” particle, that could help radically refine our understanding of Standard Model of Particle Physics. For years scientists at CERN have been harnessing the power of the Large Hadron Collider to answer fundamental questions about the nature of particles and the universe around us. In the above video John Ellis, a theoretical physicist, answers the question “What is the Higgs Boson?” The video pairs nicely with the CERN press release: “We observe in our data clear signs of a new particle, at the level of 5 sigma, in the mass region around 126 GeV. The outstanding performance of the LHC and ATLAS and the huge efforts of many people have brought us to this exciting stage,” said ATLAS experiment spokesperson Fabiola Gianotti, “but a little more time is needed to prepare these results for publication.” “The results are preliminary but the 5 sigma signal at around 125 GeV we’re seeing is dramatic. This is indeed a new particle. We know it must be a boson and it’s the heaviest boson ever found,” said CMS experiment spokesperson Joe Incandela. “The implications are very significant and it is precisely for this reason that we must be extremely diligent in all of our studies and cross-checks.” “It’s hard not to get excited by these results,” said CERN Research Director Sergio Bertolucci. “ We stated last year that in 2012 we would either find a new Higgs-like particle or exclude the existence of the Standard Model Higgs. With all the necessary caution, it looks to me that we are at a branching point: the observation of this new particle indicates the path for the future towards a more detailed understanding of what we’re seeing in the data.” How to Use an Xbox 360 Controller On Your Windows PC Download the Official How-To Geek Trivia App for Windows 8 How to Banish Duplicate Photos with VisiPic

  • Mini-ITX board for AM3 Athlon X4 600e processor.

    - by Kamil Zadora
    Hello, I am planning to build a PC to control a robotic platform that I am building (about 50% complete). I need more power than ATOM platform could bring, as the robot will need to do on the fly image processing to work as intended. I was considering using Athlon X4 600e as it is rated 45W Maximum output. Probably underclocked it would go lower than 30-35W. I do not I'am at very long battery life, but the 17Ah, 12V battery should keep it running for few hours. My problem is: motherboard. I am space limited so I am looking for a nice mini-itx AM3 motherboard to match the processor. It is hard to find many tests about power usage of the motherboards itself (for example, when using the same processor on different motherboards, test are usualy done in the opposite matter). Could you provide any motherboard examples or suggest what chipset to look for? Thank you in advance.

  • Movember 2012

    - by Tim Koekkoek
    If you were lucky enough to visit one of the Oracle Dublin offices during the month November you may have noticed a bunch of mustached merchants. If you thought the mustache was the newest hair fashion in Ireland you were wrong. These guys were the Mo Bro’s and proud members of MOracle, our Movember 2012 team. The aim of Movember is to raise vital funds and awareness for men’s health, especially prostate cancer. To raise these funds, men don't shave their upper lips for a whole month and get sponsored for it by friends, family and colleagues. To highlight the importance of supporting this cause, take a look at these statistics: •             1 out of 8 men will be diagnosed with prostate cancer during their life. •             This year more than 2,000 new cases of disease will be diagnosed. •             1 out of 3 men will be diagnosed with cancer during their life. It was a long and heavy month for all the Mo Bro’s, but in the end the effort has paid off. Under the leadership of team captain Jimmy this team managed to raise over €4,400  and was ranked #34 out of 1142 Irish Movember teams. The team couldn't have done it without the constant support of our colleagues and sponsors. Many thanks to all of you! We are very happy to have raised money and awareness for men’s health. On top of that we are also happy to have raised awareness for the most underrated and abandoned piece of man’s hair… the mustache. This is just the beginning; soon many men will proudly wear this fashionable look again!

  • Hack Apart a Highlighter to Create UV-Reactive Flowers [Science]

    - by ETC
    College students have long been hacking apart highlighters to create glowing bottles of booze to line their dorm room walls. Far more interesting, however, is the application of the hack to flowers. Many of you may remember a science class experiment from years gone by where in you put food coloring in a beaker and then some freshly cut white flowers; returning to the experiment a day later yielded flowers colored to match the dye you added. This little experiment relies on the same technique, only instead of blue food coloring the flowers suck up UV-reactive highlighter dye.

  • Diagram that could explain a state machine's code?

    - by Incognito
    We have a lot of concepts in making diagrams like UML and flowcharting or just making up whatever boxes-and-arrows combination works at the time, but I'm looking at doing a visual diagram on something that's actually really complex. State machines like those that parse HTML or regular expressions tend to be very long and complicated bits of code. For example, this is the stateLoop for FireFox 9 beta. It's actually generated by another file, but this is the code that runs. How can I diagram something with the complexity of this in a way that explains flow of the code without taking it to a level where I draw every single line-of-code into it's own box on a flowchart? I don't want to draw "Invoke loop, then return" but I don't want to explain every last detail. What kind of graph is suitable to do this? Is there already something out there similar to this? Just an example of how to do this without going overboard in complexity or too-high-level is really what I want. If you don't feel like looking at the code, basically it's 70 different state flags that could occur, inside an infinite loop that exists to a label based on some conditions, each flag has it's own infinite loop that exists to a label somewhere, and each of those loops has checks for different types of chars, which then runs off into various other methods.

  • Upgrade Mysql to 5.5 with cPanel

    - by Merrill
    I have a cPanel installed on a CentOS server and it includes an old version of Mysql. Has anyone tried upgrading Mysql to 5.5 on a cPanel managed server? If so, I would really like some guidance. I read, on the cPanel forum, that it's not supported and one user complained, after manually upgrading his version of Mysql, cPanel automatically removed it, but that was a long time ago. Also, I'm a newbie to Linux, so please forgive any dumb questions. Help... Thanks.

  • How should I work out VAT (UK tax) in my eCommerce site?

    - by Leonard Challis
    We have an ecommerce system in place. The sales actually go through Sage, so we have an export script from our system that uses a third-party Sage Importer program. With a new version of this importer, values are checked more thoroughly. We are getting 1 pence discrepancies because of the way rounding works - our system has always held prices and worked to 4 decimal places. In the checkout the totals would be worked out first, then the rounding to 2 decimal places. The importer does rounding first, though. So, for instance: Our way: Product 1: £13.4561 Qty: 2 Total inc VAT = £32.29 (to 2dp) Importer way: Our way: Product 1: £13.4561 Qty: 2 Total inc VAT = £32.30 (to 2dp) Management are reluctant to lose the 4dp but the developers of the Sage importer have said that this is correct and makes sense -- you woudn't sell a product for £13.4561 in a shop, nor would you charge someone tax at 4 decimal places. I contacted the HMRC and the operator didn't really give me much to go on, telling me a technician would phone back, to which they haven't and I'm still waiting after almost a week and numerous follow-up calls. I did find a PDF on the HMRC's web site, but this did about us much to confuse me as it did to answer my questions. I see that they're happy for people to round up or down, as long it is consistent, but I can't tell whether it should be done on a line by line basis or on the end total of the order. We are now in the position where we need to decide whether it's worth us doing one of the following, or something completely different. Please advise with any experience or information I can read. Change all products on the site to use 2dp Keep 4dp but round each line in the order to 2dp before working out tax Keep it as it is and "fudge" the values at the export script (i.e. make that values correct by adding or subtracting 1p and changing the shipping cost to make the totals still work out) Any thoughts?

  • Which version of rails should I install with ruby 2.0.0 installed?

    Hi I am building a ROR development environment on a new computer with windows 7, now I have Ruby version 2.0.0 and Gems version 2.2.2 installed. Which version of Rails should I install? I saw this on rubyonrails.org/download : "We recommend Ruby 2.1.0 for use with Rails. We stopped supporting Ruby 1.8.x after Rails 3.2. Ruby 1.9.2+ will be supported until Rails 5." I will be working on a long-time project, I'm just trying to lessen the headaches I will have later. Right now, the latest Rails -v is 4.1.0 and they recommend Ruby 2.1.0 for use with Rails. I think the best option is to go with this set. Any other thoughts?

  • What should I quote for a project I hope to get a job at the end of?

    - by thesunneversets
    Long story short: I applied for a (CakePHP, MySQL, etc) development job in London, UK. I grew up in Britain but am currently based quite a few thousand miles away in Canada, so I wasn't really expecting success. But quite a few emails and phone interviews later it seems that they really like me. At least to a point. Because such a major relocation would be a horrible thing to go wrong, they've sensibly suggested a trial run of getting me to build a website at a distance. I have the spec for this and it's quite a substantial amount of work. My problem is that I now need to suggest both a fee and a timescale for the job, and I haven't got any significant experience of working as a contractor. Looking at the spec, which is 1500 words of many concisely stated features, some fairly trivial and some moderately involved, I can easily imagine there being 2 weeks of intensive work there. (If everything went really well it might be closer to one week, but even though I want to impress, I definitely don't want to fall into the inexperienced-contractor trap of massively underestimating the amount of time a project will run to.) As an extra complication, there is no expectation that I should give up my day job to get this trial project done, so the hours will have to be clawed from evenings and weekends. I don't want to overcommit to a quick delivery date, only to find myself swiftly burning out due to an unrealistic workload. So, any advice for me? My main question is, what is a realistic hourly figure to demand of a stable but not excessively wealthy London-based company in the current market, bearing in mind that I'd like them to hire me afterwards? But any more general recommendations based on my circumstances above would be much appreciated too. Many thanks!

  • Can Acer Aspire Revo (Atom 330) be used with two monitors simultaneously?

    I'm so attracted to Acer Revo for the price & the look. As long as I can work on two monitors simultaneously, I'll be happy. Not planning to do heavy video editing or gaming. Occasional movie streaming would be fine. Will mainly use it to do trading, lots of word processing, some photo editing, connecting with friends. Anyone has experience using Revo with 2 or more monitors? The spec says it has VGA and HDMI output but Acer sales person over the phone told me it can support one monitor only..??

    Hello, We are in the transition from Novell NetWare to Windows server 2008. In case of the printer server we print jobs thousands of pages long. NetWare printer manager has a handy function which allows to rewind a print job to a specified page. In case of a paper jam at the 750 page on a 800 page document this is really convenient. Does anybody know if there is a solution for this? The lists printed are in plain ascii lists with printer command characters embedded, and we are using dot matrix printers.

  • Mexico leading in Business Transformation Strategies:

    - by [email protected]
    By [email protected] on April 15, 2010 8:31 AM By John Burke Group Vice President Oracle Applications Business Unit I recently completed a business tour in Mexico, and was surprised by both the economic vibrancy of the country and the thought leadership expressed by many of the customers I met. An example of the economic vibrancy of the country: across the street from my hotel was the local Bentley dealership, Coach Store, Yves Saint Laurent and of course a Starbucks. I only made it to Starbucks. Both the Coach Store and YSL had a line of folks waiting to get in... As for thought leadership, there were several illustrations only on the first day. I had the opportunity to meet with a branch of the Mexican Federal Government. Their questions were not about clerical task automation, far from it! We discussed citizen on-line access to fees and services - for example looking up the duty on an international goods shipment, or tracking that my taxes have been received, or the status of my request for a certain service. Eligibility, policies and status. Having an integrated rules or policy automation system that would allow businesses and citizens to access accurate information and ensure the proper collection of fees and payment for 3rd party provided services. Then in the afternoon, I met with the owner of a roofing company (note: most roofs in Mexico are flat and made of cement). This CEO started discussing how he wanted to transform his business from a cement products company to a service company and market 5-10-15 year service contracts which would guarantee the structural integrity of the roof and of course that the roof would remain waterproof. Although his products were guaranteed, they required an annual inspection and most home owners never schedule that inspection until it is too late and water damage has occurred. These emergency calls reduce his margin and reduce customer satisfaction. This lead to a discussion of business models in general and why long term differentiation can only come from service, not just for the music or news industries, but also for roofing companies! I completely agreed with the transformational concepts described in both meetings and quickly understood why there is a Bentley dealership near my hotel.

  • Hex Dump using LINQ (in 7 lines of code)

    - by Fabrice Marguerie
    Eric White has posted an interesting LINQ query on his blog that shows how to create a Hex Dump in something like 7 lines of code.Of course, this is not production grade code, but it's another good example that demonstrates the expressiveness of LINQ.Here is the code:byte[] ba = File.ReadAllBytes("test.xml");int bytesPerLine = 16;string hexDump = ba.Select((c, i) => new { Char = c, Chunk = i / bytesPerLine })    .GroupBy(c => c.Chunk)    .Select(g => g.Select(c => String.Format("{0:X2} ", c.Char))        .Aggregate((s, i) => s + i))    .Select((s, i) => String.Format("{0:d6}: {1}", i * bytesPerLine, s))    .Aggregate("", (s, i) => s + i + Environment.NewLine);Console.WriteLine(hexDump); Here is a sample output:000000: FF FE 3C 00 3F 00 78 00 6D 00 6C 00 20 00 76 00000016: 65 00 72 00 73 00 69 00 6F 00 6E 00 3D 00 22 00000032: 31 00 2E 00 30 00 22 00 20 00 65 00 6E 00 63 00000048: 6F 00 64 00 69 00 6E 00 67 00 3D 00 22 00 75 00000064: 3E 00Eric White reports that he typically notices that declarative code is only 20% as long as imperative code.

  • Installation of SQL Server 2008 r2 express - Service accounts

    - by Shimmy
    hello! I am in middle of installing SQL Server 2008 r2 express, where an existing instance has been installed long ago. I need to install a new instance. During the installation I reach a tab where I am supposed to enter accounts for "SQL Server Database Engine" and Browser. The browser is already selected, my question is about the 1st row. What account should I enter? I need to be able to perform SQL queries from SMSS and from my app, thru windows authentication.

  • OpenSource License Validation [closed]

    - by Macmade
    I'm basically looking for some kind of FLOSS/OpenSource license validation service. I have special needs for some projects I'd like to open-source. I know there's actually tons of different FLOSS/OpenSource licenses, each one suitable for some specific purpose, and that creating a «new» one is not something recommended, usually. Anyway, even if I'm not an expert in the legal domain, I've got some experience with FLOSS/OpenSource, at a legal level, and it seems there's just no license covering my needs. I actually wrote the license terms I'd like to use, and contacted the FSF, asking them to review that license, as it seems (at least that's written on their website) they can do such review work. No answer. I tried repetitively, but no luck. So I'm currently looking for an alternate legal expertise about that specific license. I don't mind paying such a service, as long as I can be sure the license can be recognised as a FLOSS/OpenSource license. About the license, it's basically a mix of a BSD (third-clause) with a BOOST software license. The difference is about redistribution. Source code redistribution shall retain the copyright novices. The same applies for binary redistribution (like BSD), unless it's distributed as a library (more like BOOST). I hope this question is OK for programmers.stackexchange. I'm usually more active on StackOverflow, but it just seems the right place for such a question. So thank you for your time and enlightened advices. : )

  • Bad style programming, am I pretending too much?

    - by Luca
    I realized to work in an office with a quite bad code base. The base library implemented in years and years is quite limited, and most of that code is, honestly, horrible. Projects developed in the office are very large. Fine. I could define me a "perfectionist" (but often I'm not), and I thought to refactor an application (really a portion), which need a new (complex) feature. But, today, I really realized that it's not possible to refactor that application modules with a reasonable time (say, 24/26 hours, respect the avaialable time for the task, which is 160 hours). I'm talking about (I am a bit ashamed to say) name collisions, large and frequent cut & paste code, horrible and misleading naming, makefiles without dependencies (!), application login is spread randomly across many different sources, dead code, variable aliasing, no assertion, no documentation, very long source files, bad/incomplete include file definition, (this is emblematic!) very frequent extern declaration of variables and functions, ... I'm sure to continue ... buffer overflows because sprintf, indentation (!), spacing, non existent const modifier usage. I would say that every source line was written quite randomly when needed, without keeping in mind some design (at least, the obvious one). (Am I in hell?) The problem arises when the application is developed by a colleague of mine. I felt very frustrated. So, I decided to expose the "situation" to my colleague; at the end, that was a bad idea. He is justified in saying that "the application was developed in haste, so it is natural that it is written vaguely; you are wasting time to think and implement an elegant implementation" .... I'm asking too much from my colleague to write readable code, which is managed and documented? I expect too much in not having to read thousands of lines of code to understand how a particular logic?
