  - by Diego Garcia

  I've installed Ubuntu 10.04 on a Satellite L35-SP1011 and there's no sound. Actually i have many video problems cause i had to disable effect because when it had effect activated, laptop got frozen many times. I saw this problem but in older ubuntu versions and tried some fixes without success. Any idea on how to solve my audio and video problems? I've tried these instructions https://help.ubuntu.com/community/RadeonDriver without success. My video card is a ATI Express 200M. lspci output 00:14.2 Audio device: ATI Technologies Inc IXP SB4x0 High Definition Audio Controller (rev 01) 00:14.3 ISA bridge: ATI Technologies Inc IXP SB400 PCI-ISA Bridge (rev 80) 00:14.4 PCI bridge: ATI Technologies Inc IXP SB400 PCI-PCI Bridge (rev 80) 01:05.0 VGA compatible controller: ATI Technologies Inc RC410 [Radeon Xpress 200M] complete lspci output at http://pastebin.com/AVk1WWQt Update #1 - It's the same on Ubuntu 10.10 and Kubuntu 10.10... Slow graphics, and no sound. Update #2 - Sound SOLVED I edited /etc/modprobe/alsa-base.conf in Ubuntu 10.10 and added options snd-hda-intel model=asus Now i'm working on video, I added xorg-edgers ppa, updated and upgraded without big difference... it's working better but without transparency.

• NetBeans Sources as a Platform

  - by Geertjan

  By default, when you create a new NetBeans module, the 'development IDE' is the platform to which you'll be deploying your module. It's a good idea to create your own platform and check that into your own repo, so that everyone working on your project will be able to work with a standardized platform, rather than whatever happens to be beneath the development IDE your using. Something else you can do is use the NetBeans sources as your platform, once you've checked them out. That's something I did the other day when trying to see whether adding 'setActivatedNodes' to NbSheet was sufficient for getting UndoRedo enabled in the Properties Window. So that's a good use case, i.e., you'd like to change the NetBeans Platform somehow, or you're fixing a bug, in other words, in some way you need to change the NetBeans Platform sources and then would like to try out the result of your changes as a client of your changes. In that scenario, here's how to set up and use a NetBeans Platform from the NetBeans sources. Run 'ant build platform' on the root of the NetBeans sources. You'll end up with nbbuild/netbeans containing a subfolder 'platform' and a subfolder 'harness'. There's your NetBeans Platform. Go to Tools | NetBeans Platform and browse to nbbuild/netbeans', registering it as your NetBeans Platform. Create a new NetBeans module, using the new NetBeans Platform as the platform. Now the cool thing is you can open any of the NetBeans modules from the NetBeans Platform modules in the NetBeans sources. When you change the source code of one of these modules and then build that module, the changed JAR will automatically be added to the right place in the nbbuild/netbeans folder. And when you do a 'clean' on a NetBeans Platform module, the related JAR will be removed from nbbuild/netbeans. In other words, in this way, by changing the NetBeans sources, you're directly changing the platform that your custom module will be running on when you deploy it. That's pretty cool and gives you a more connected relationship to your platform, since you're able to change it in the same way as the custom modules you create.

• Thoughts on web development architecture through integrating C++ in the future to a web application

  - by Holland

  I'm looking to build a website (it's actually going to be a commercial startup) I saw this question and it really shed some light on a few things that I was hoping to understand (kudos to the op). After seeing that, it would make sense that, unless the website were required to actually have millions of hits per day, it wouldn't be a viable solution to write a C++ backend on the server side. But this got me thinking. what if it in the (unlikely) events of the future, it does go that route? The problem is that, while I'm thinking of starting this all using .Net (in the beginning) just to get something quick and easy up without a lot of hassle (in terms of learning), and then moving towards something more Open Source (such as Python/Django or RoR) later to save money and to support OSS, I'm wondering IFF the website actually becomes big, will it be a good idea to integrate a C++ backend, and use Python ontop of C++ for a strong foundation, and then mitigate HTML/CSS/AJAX/etc ontop of the backend's foundation? I guess, what I'd like to know is that, given the circumstance, if this were to happen, would it be a proper approach in terms of architecture? I'd definitely be supporting MVC as that seems to be a great way to implement a website. All in all, would one consider this rational, or are there other alternatives? I like .Net, and I'd like to use it in the beginning, because I have much more experience with that than, say, Python or PHP, and I prefer it in general, but I really do want to support OSS in the future. I suppose the sentence I'm looking for is, "is this pragmatic?"

• The Strange History of the Honeywell Kitchen Computer

  - by Jason Fitzpatrick

  In 1969 the Honeywell corporation released a $10,000 kitchen computer that weighed 100 pounds, was as big as a table, and required advanced programming skills to use. Shockingly, they failed to sell a single one. Read on to be dumbfounded by how ahead of (and out of touch with) its time the Honeywell Kitchen Computer was. Wired delves into the history of the device, including how difficult it was to use: Now try to imagine all that in late 1960s kitchen. A full H316 system wouldn’t have fit in most kitchens, says design historian Paul Atkinson of Britain’s Sheffield Halam University. Plus, it would have looked entirely out of place. The thought that an average person, like a housewife, could have used it to streamline chores like cooking or bookkeeping was ridiculous, even if she aced the two-week programming course included in the $10,600 price tag. If the lady of the house wanted to build her family’s dinner around broccoli, she’d have to code in the green veggie as 0001101000. The kitchen computer would then suggest foods to pair with broccoli from its database by “speaking” its recommendations as a series of flashing lights. Think of a primitive version of KITT, without the sexy voice. Hit up the link below for the full article.

• How to configure SoapUI with client certificate authentication

  - by gvdmaaden

  SoapUI is one of the best free tools around to test web services. Some time ago I was trying to send a soap message towards a SSL web service that was set up for client certificate authentication. I pretty soon got stuck at the “javax.net.ssl.SSLException: HelloRequest followed by an unexpected handshake message” error, but after reading several posts on the internet I solved that issue. It’s not really that complicated after all, but since I could not find a decent place on the internet that explains this scenario in a proper way, here’s a list of steps that you need to do to make it work. Note: this following steps are based on a Windows environment   Step one: Export your certificate (the one that you want to use as the client certificate) using the export wizard with the private key and with all certificates in the certification path: Give it a password (anything you want): And export it as a PFX file to a location somewhere on disk: Step two: Install the newest version of SOAP UI (currently it is 3.6.1) Open the file C:\Program Files\eviware\soapUI-3.6.1\bin\ soapUI-3.6.1.vmoptions and add this line at the bottom: -Dsun.security.ssl.allowUnsafeRenegotiation=true This is needed because of a JAVA security feature in their newest frameworks (For further reading about this issue, read this: http://www.soapui.org/forum/viewtopic.php?t=4089 and this: http://java.sun.com/javase/javaseforbusiness/docs/TLSReadme.html).   Open SOAPUI and go to preferences>SSL Settings and configure your certificate in the keystore (use the same password as in step one): That should be it. Just create a new project and import the WSDL from the client authenticated SSL webservice: And now you should be able to send soap messages with client certificate authentication. The above steps worked for me, but please drop a note if it does not work for you.

• PHP remote development workflow: git, symfony and hudson

  - by user2022

  I'm looking to develop a website and all the work will be done remotely (no local dev server). The reason for this is that my shared hosting company a2hosting has a specific configuration (symfony,mysql,git) that I don't want to spend time duplicating when I can just ssh and develop remotely or through netbeans remote editing features. My question is how can I use git to separate my site into three areas: live, staging and dev. Here's my initial thought: public_html (live site and git repo) testing: a mirror of the site used for visual tests (full git repo) dev/ticket# : git branches of public_html used for features and bug fixes (full git repo) Version Control with git: Initial setup: cd public_html git init git add * git commit -m ‘initial commit of the site’ cd .. git clone public_html testing mkdir dev Development: cd /dev git clone ../testing ticket# all work is done in ./dev/ticket#, then visit www.domain.com/dev/ticket# to visually test make granular commits as necessary until dev is done git push origin master:ticket# if the above fails: merge latest testing state into current dev work: git merge origin/master then try the push again mark ticket# as ready for integration integration and deployment process: cd ../../testing git merge ticket# -m "integration test for ticket# --no-ff (check for conflicts ) run hudson tests visit www.domain.com/testing for visual test if all tests pass: if this ticket marks the end of a big dev sprint: make a snapshot with git tag git push --tags origin else git push origin cd ../public_html git checkout -f (live site should have the latest dev from ticket#) else: revert the merge: git checkout master~1; git commit -m "reverting ticket#" update ticket# that testing failed with the failure details Snapshots: Each major deployment sprint should have a standard name and should be tracked. Method: git tag Naming convention: TBD Reverting site to previous state If something goes wrong, then revert to previous snapshot and debug the issue in dev with a new ticket#. Once the bug is fixed, follow the deployment process again. My questions: Does this workflow make sense, if not, any recommendations Is my approach for reverting correct or is there a better way to say 'revert to before x commit'

• DevDays ‘00 The Netherlands day #2

  - by erwin21

  Day 2 of DevDays 2010 and again 5 interesting sessions at the World Forum in The Hague. The first session of the today in the big world forum theater was from Scott Hanselman, he gives a lap around .NET 4.0. In his way of presenting he talked about all kind of new features of .NET 4.0 like MEF, threading, parallel processing, changes and additions to the CLR and DLR, WPF and all new language features of .NET 4.0. After a small break it was ready for session 2 from Scott Allen about Tips, Tricks and Optimizations of LINQ. He talked about lazy and deferred executions, the difference between IQueryable and IEnumerable and the two flavors of LINQ syntax. The lunch was again very good prepared and delicious, but after that it was time for session 3 Web Vulnerabilities and Exploits from Alex Thissen. This was no normal session but more like a workshop, we decided what kind of subjects we discussed, the subjects where OWASP, XSS and other injections, validation, encoding. He gave some handy tips and tricks how to prevent such attacks. Session 4 was about the new features of C# 4.0 from Alex van Beek. He talked about Optional- en Named Parameters, Generic Co- en Contra Variance, Dynamic keyword and COM Interop features. He showed how to use them but also when not to use them. The last session of today and also the last session of DevDays 2010 was about WCF Best Practices from Gerben van Loon. He talked about 7 best practices that you must know when you are going to use WCF. With some quick demos he showed the problem and the solution for some common issues. It where two interesting days and next year i sure will be attending again.

• I spoke at SQL Saturday #77 and all I got was this really awesome speaker's shirt!

  - by Most Valuable Yak (Rob Volk)

  Yeah, it was 2 weeks ago, but I'm finally blogging about something! I presented Revenge: The SQL! at SQL Saturday #77 in Pensacola on June 4.  The session abstract is here, and you can download the slides from that page too.  You can see how I look in the speaker's shirt here. Overall it went pretty well.  I discovered a new bit of evil just that morning and in a carefully considered, agonizing decision-making process that was full documented, tested, and approved…nah, I just went ahead and added it at the last minute.  Which worked out even better than (not) planned, since it screwed me up a bit and made my point perfectly.  I had a few fans in the audience, and one of them recorded it for blackmail material posterity. I'd like to thank Karla Landrum (blog | twitter) and all the volunteers for putting together such a great event, and for being kind enough to let me present. (Note to Karla: I'll get the next $100 to you as soon as I can.  Might need a few extra days on the next $100.) Thanks to Audrey (blog | twitter), Peg, and Dorothy for attending and keeping the heckling down.  Thanks also to Aaron (blog | twitter) for providing room and board and also not heckling.  Thanks to Julie (blog | twitter) for coming up with the title for the presentation.  (boo to Julie for getting sick and bailing out on us)  And thanks to all of them for listening to a preview and offering their suggestions and advice! Cross your fingers that I get accepted at SQL Saturday 81 in Birmingham, SQL Saturday 85 in Orlando, or SQL Saturday 89 in Atlanta, or just attend them anyway!

• Ruby Shoes for non-trivial apps

  - by marcof

  I've been taking a look at Ruby Shoes for GUI development with Ruby. So far, it's been a pretty good experience for making simple apps. However, I am quite worried about being able to write large scale applications with it. For example, how would I go about using MVP pattern with this framework ? For now, I have not been able to not make presentation concerns leak into the view because of the lack of some kind of "data binding". I have code that looks like this : Shoes.app do @view = SampleView.new @presenter = SamplePresenter.new @view @label = para @view.sample_property button "Update sample_property" do @presenter.update_sample_property end end Here, the call to @presenter.update_sample_property updates @view.sample_property but the label is not updated accordingly. For this to work, I would have to make @presenter.update_sample_property to return a string, and then call @label.text = return_value, but I think that would violate the MVP principle of not having presentation logic in the view. I'm used to work in .Net with the MVP pattern so I don't know if the pattern applies correctly to Shoes like I tried to do. Are there any ressources out there for making non-trivial apps with Shoes ? Especially using the MVP pattern or something similar ? EDIT : I took a look at the shoebox to see what other people have achieved with the framework. Though I did not look through it extensively, at first sight it seems like they are all simple projects with no real purposes.

• Generating Normal map from a Image with a given Albedo map

  - by snape

  I am working on a research problem part of which involves generating normal map from a given image of a rusted object. I searched the internet for techniques to achieve the above and apparently crazybump is mentioned a lot. I tried it but it didn't produce the desirable effects. Also I am looking for a method which draws inspiration from an existing research paper not some closed source software. I turned my attention to the technique described in the this paper. Results from this technique are satisfactory for normal objects because of bias in the training data but it doesn't work very well in the case of rusted objects. After this I focussed my attention on generating Albedo map (the above problem would become more solvable if Albedo map is obtained). Fortunately I am able to generate pretty good albedo maps for images of rusted objects. I used this paper's approach to generate Albedo maps. Now I want to know a good technique to get Normal map given an image and it's corresponding Albedo map. To give you an idea of what kind of images I am working with I am attaching a sample. Links to research material would be really appreciated. Thanks!

• Cross-platform desktop programming: C++ vs. Python

  - by John Wells

  Alright, to start off, I have experience as an amateur Obj-C/Cocoa and Ruby w/Rails programmer. These are great, but they aren't really helpful for writing cross-platform applications (hopefully GNUStep will one day be complete enough for the first to be multi platform, but that day is not today). C++, from what I can gather, is extremely powerful but also a huge, ugly behemoth that can take half a decade or more to master. I've also read that you can very easily not only shoot yourself in the foot, but blow your entire leg off with it since memory management is all manual. Obviously, this is all quite intimidating. Is it correct? Python seems to provide most of the power of C++ and is much easier to pick up at the cost of speed. How big is this sacrifice? Is it meaningful or can it be ignored? Which will have me writing fast, stable, highly reliable applications in a reasonable amount of time? Also, is it better to use Qt for your UI or instead maintain separate, native front ends for each platform? EDIT: For extra clarity, there are two types applications I want to write: one is an extremely friendly and convenient database frontend and the other, which no doubt will come much later on, is a 3D world editor.

• Get to Know a Candidate (15 of 25): Jerry White&ndash;Socialist Equality Party

  - by Brian Lanham

  DISCLAIMER: This is not a post about “Romney” or “Obama”. This is not a post for whom I am voting. Information sourced for Wikipedia. White (born Jerome White) is an American politician and journalist, reporting for the World Socialist Web Site.  White's Presidential campaign keeps four core components: * International unity in the working class * Social equality * Opposition to imperialist militarism and assault on democratic rights * Opposition to the political subordination of the working class to the Democrats and Republicans The White-Scherrer ticket is currently undergoing a review by the Wisconsin election committee concerning the ballot listing of the party for the 2012 Presidential elections. White has visited Canada, Germany, and Sri Lanka to campaign for socialism and an international working class movement. The Socialist Equality Party (SEP) is a Trotskyist political party in the United States, one of several Socialist Equality Parties around the world affiliated to the International Committee of the Fourth International (ICFI). The ICFI publishes daily news articles, perspectives and commentaries on the World Socialist Web Site. The party held public conferences in 2009 and 2010. It led an inquiry into utility shutoffs in Detroit, Michigan earlier in 2010, after which it launched a Committee Against Utility Shutoffs. Recently it sent reporters to West Virginia to report on the Upper Big Branch Mine disaster and the way that Massey Energy has treated its workers. It also sent reporters to the Gulf Coast to report on the Deepwater Horizon oil spill. In addition, it has participated in elections with the aim of opposing the American occupation of Iraq and building a mass socialist party with an international perspective. Despite having been active for over a decade, the Socialist Equality Party held its founding congress in 2008, where it adopted a statement of principles and a historical document.

• 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?

• AutoHotkey cannot interact with Windows 8 Windows&hellip;or can it!

  - by deadlydog

  If you’ve installed Windows 8 and are trying to use AutoHotkey (AHK) to interact with some of the Winodws 8 Windows (such as the Control Panel for example), or with apps that need to be Ran As Administrator, then you’ve likely become very frustrated as I did to discover that AHK can not send any commands (keyboard or mouse input) to these windows.  This was a huge concern as I often need to run Visual Studio as an administrator and wanted my hotkeys and hotstrings to work in Visual Studio.  After a day of fighting I finally realized the answer (and it’s pretty obvious once you think about it).  If you want AHK to be able to interact with Windows 8 Windows or apps running as administrator, then you also need to have your AHK script Run As Administrator. If you are like me then you probably have your AHK scripts set to run automatically at login, which means you don’t have the opportunity to right-click on the script and manually tell it to Run As Administrator.  Luckily the work around is simple.  First, if you want to have your AHK script (or any program for that matter) run when you log in, create a shortcut to the application and place the shortcut in: C:\Users\[User Name]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup Note that you will need to replace “[User Name]” with your username, and that “AppData” is a hidden folder so you’ll need to turn on viewing hidden folders to see it.  So by placing that shortcut there Windows will automatically run your script when you log on.  Now, to get it to run as an administrator by default, right-click on the shortcut and go to Properties.  Under the Shortcut tab, click on the “Advanced…” button and check off “Run as administrator”.  That’s it.  Now when you log onto Windows your script will automatically start up, running as an administrator; allowing it to interact with any application and window like you had expected it to in the first place.   Happy coding!

• Smart defaults [SSDT]

  - by jamiet

  I’ve just discovered a new, somewhat hidden, feature in SSDT that I didn’t know about and figured it would be worth highlighting here because I’ll bet not many others know it either; the feature is called Smart Defaults. It gets around the problem of adding a NOT NULLable column to an existing table that has got data in it – previous to SSDT you would need to define a DEFAULT constraint however it does feel rather cumbersome to create an object purely for the purpose of pushing through a deployment – that’s the situation that Smart Defaults is meant to alleviate. The Smart Defaults option exists in the advanced section of a Publish Profile file: The description of the setting is “Automatically provides a default value when updating a table that contains data with a column that does not allow null values”, in other words checking that option will cause SSDT to insert an arbitrary default value into your newly created NON NULLable column. In case you’re wondering how it does it, here’s how: SSDT creates a DEFAULT CONSTRAINT at the same time as the column is created and then immediately removes that constraint: ALTER TABLE [dbo].[T1]    ADD [C1] INT NOT NULL,         CONSTRAINT [SD_T1_1df7a5f76cf44bb593506d05ff9a1e2b] DEFAULT 0 FOR [C1];ALTER TABLE [dbo].[T1] DROP CONSTRAINT [SD_T1_1df7a5f76cf44bb593506d05ff9a1e2b]; You can then update the value as appropriate in a Post-Deployment script. Pretty cool! On the downside, you can only specify this option for the whole project, not for an individual table or even an individual column – I’m not sure that I’d want to turn this on for an entire project as it could hide problems that a failed deployment would highlight, in other words smart defaults could be seen to be “papering over the cracks”. If you think that should be improved go and vote (and leave a comment) at [SSDT] Allow us to specify Smart defaults per table or even per column. @Jamiet

• SQLAuthority News – Scaling Up Your Data Warehouse with SQL Server 2008 R2

  - by pinaldave

  Data Warehouses are suppose to be containing huge amount of the data from the beginning. However, there are cases when too big is not enough. Every Data Warehouse Admin will agree that they have faced situation where they will need to scale up their data warehouse. Microsoft has released white paper discussing the same. Here is the abstract from the Microsoft Official site: SQL Server 2008 introduced many new functional and performance improvements for data warehousing, and SQL Server 2008 R2 includes all these and more. This paper discusses how to use SQL Server 2008 R2 to get great performance as your data warehouse scales up. We present lessons learned during extensive internal data warehouse testing on a 64-core HP Integrity Superdome during the development of the SQL Server 2008 release, and via production experience with large-scale SQL Server customers. Our testing indicates that many customers can expect their performance to nearly double on the same hardware they are currently using, merely by upgrading to SQL Server 2008 R2 from SQL Server 2005 or earlier, and compressing their fact tables. We cover techniques to improve manageability and performance at high-scale, encompassing data loading (extract, transform, load), query processing, partitioning, index maintenance, indexed view (aggregate) management, and backup and restore. Scaling Up Your Data Warehouse with SQL Server 2008 R2 Reference: Pinal Dave (http://blog.SQLAuthority.com)   Filed under: PostADay, SQL, SQL Authority, SQL Documentation, SQL Download, SQL Query, SQL Server, SQL Tips and Tricks, T SQL, Technology

• 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.

• Game software design

  - by L. De Leo

  I have been working on a simple implementation of a card game in object oriented Python/HTML/Javascript and building on the top of Django. At this point the game is in its final stage of development but, while spotting a big issue about how I was keeping the application state (basically using a global variable), I reached the point that I'm stuck. The thing is that ignoring the design flaw, in a single-threaded environment such as under the Django development server, the game works perfectly. While I tried to design classes cleanly and keep methods short I now have in front of me an issue that has been keeping me busy for the last 2 days and that countless print statements and visual debugging hasn't helped me spot. The reason I think has to do with some side-effects of functions and to solve it I've been wondering if maybe refactoring the code entirely with static classes that keep no state and just passing the state around might be a good option to keep side-effects under control. Or maybe trying to program it in a functional programming style (although I'm not sure Python allows for a purely functional style). I feel that now there's already too many layers that the software (which I plan to make incredibly more complex by adding non trivial features) has already become unmanageable. How would you suggest I re-take control of my code-base that (despite being still only at < 1000 LOC) seems to have taken a life of its own?

• Do you think natively compiled languages have reached their EOL?

  - by Yuval A

  If we look at the major programming languages in use today it is pretty noticeable that the vast majority of them are, in fact, interpreted. Looking at the largest piece of the pie we have Java and C# which are both enterprise-ready, heavy-duty, serious programming languages which are basically compiled to byte-code only to be interpreted by their respective VMs (the JVM and the CLR). If we look at scripting languages, we have Perl, Python, Ruby and Lua which are all interpreted (either from code or from bytecode - and yes, it should be noted that they are absolutely not the same). Looking at compiled languages we have C which is nowadays used in embedded and low-level, real-time environments, and C++ which is still alive and kicking, when you want to get down to serious programming as close to the hardware as you can, but still have some nice abstractions to help you with day to day tasks. Basically, there is no real runner-up compiled language in the distance. Do you feel that languages which are natively compiled to executable, binary code are a thing of the past, taken over by interpreted languages which are much more portable and compatible? Does C++ mark an end of an era? Why don't we see any new compiled languages anymore? I think I should clarify: I do not want this to turn into a "which language is better" discussion, because that is not the issue at hand. The languages I gave as example are only examples. Please focus on the question I raised, and if you disagree with my statement that compiled languages are less frequent these days, that is totally fine, I am more than happy to be proved mistaken.

• Application Lifecycle Management Tools

  - by John K. Hines

  Leading a team comprised of three former teams means that we have three of everything.  Three places to gather requirements, three (actually eight or nine) places for customers to submit support requests, three places to plan and track work. We’ve been looking into tools that combine these features into a single product.  Not just Agile planning tools, but those that allow us to look in a single place for requirements, work items, and reports. One of the interesting choices is Software Planner by Automated QA (the makers of Test Complete).  It's a lovely tool with real end-to-end process support.  We’re probably not going to use it for one reason – cost.  I’m sure our company could get a discount, but it’s on a concurrent user license that isn’t cheap for a large number of users.  Some initial guesswork had us paying over $6,000 for 3 concurrent users just to get started with the Enterprise version.  Still, it’s intuitive, has great Agile capabilities, and has a reputation for excellent customer support. At the moment we’re digging deeper into Rational Team Concert by IBM.  Reading the docs on this product makes me want to submit my resume to Big Blue.  Not only does RTC integrate everything we need, but it’s free for up to 10 developers.  It has beautiful support for all phases of Scrum.  We’re going to bring the sales representative in for a demo. This marks one of the few times that we’re trying to resist the temptation to write our own tool.  And I think this is the first time that something so complex may actually be capably provided by an external source.   Hooray for less work!

• How to improve battery life on Samsung 13.3” Series 7 Ultra (NP730U3E-S01AU)?

  - by beam022

  Recently I've bought a Series 7 Ultra Samsung ultrabook and decided to change the OS from originally installed Windows 8 to Ubuntu 14.04LTS. However, it's difficult not to notice great decrease in battery life: on pre-installed Windows 8 battery would last for about 6 hours while on Ubuntu it's almost empty after 2 hours of same kind of work (wi-fi, web, vlc, spotify, intellij idea). I'm not here to say that Ubuntu's battery performance is worse than Windows, but to ask for suggestions how to improve the situation (2 hours of work is pretty poor battery life). Can you recommend some sources, applications or tips/tricks that would improve battery life on my ultrabook? I really like the Ubuntu experience, but this makes my machine much less reliable. I suspect that graphic video card might be one of the issues here. Let me give you tech specs of the ultrabook: Processor: Intel® Core™ i5 Processor 3337U (1.80GHz, 3MB L3 Cache) Chipset: Intel HM76 Graphic: AMD Radeon™ HD 8570M Graphics with 1GB gDDR3 Graphic Memory (PowerExpress) and Intel(R) HD Graphics 4000 Display: 13.3" SuperBright+ 350nit FHD LED Display (1920 x 1080), Anti-Reflective Memory: 10GB DDR3 System Memory at 1,600MHz Hard-drive: 128GB Solid-state Drive More informations here, on the official page. If it's helpful to provide additional info, I'm happy to do it, just let me know what you need. Thank you.

• Is my first employer expecting too much?

  - by priyank patel

  This is my first job as a programmer. I am working using the followig technologies: ASP.NET C# HTML CSS Javascript JQuery I work for a firm which develops software for small banking firms. Currently they have their software running in 100 firms. Their software is developed in Visual Fox Pro. I was hired to develop an online version of this software. I am the only developer. My boss is another developer, the only other developer in the firm. Therefore, my employer has a total of two developers. My boss does not have any experience with .NET development. I have been working on this project for 8 months. The progress is there, but has been very slow. I try my best to do what my boss asks. But the project just seems too ambitious for me. The company has not done have any planning for the project. They just ask me to develop what their older software provides. So I have to deal with front end, back end, review code, design architecture, and more. I have decided to give my best. I try a lot. But the project sometimes just seems to be overwhelming. Question: Is it normal for a beginner programmer to be in this place? Are my employers just expecting too much of a new programmer? As a programmer, am I lacking skills one needs to deal with this? I always feel the need to work in at least a small team, if not big one. I am just not able judge my condition. Also I am paid very low salary. I do work on Saturday as well. Please, help to clarify my judgment. Any suggestions are welcome.
