• is it possible to get a programming job in the bay area?

  - by user475119

  Is it my perception or is it reality that it is harder to get software development work in Silicon Valley, than in other population centers? My theory is that some of the best and brightest (and youngest) are all here. All working for the top tech companies. And, little ol' me, over 40, math degree (not at Standford or Berkeley), ok at algorithms, and with many skills with many programming tools and concepts, but not published, and not top my class has a bit of a tough time competing. (I'm a Python programmer, by the way.) Thanks

• Coherence on Exalogic: 6x Speeds on Half the Hardware is Possible

  - by jeckels

  Recently, Oracle Coherence released its 12c version, focused on scalability and real-time data delivery. As part of the launch, we showcased Coherence's tight coupling with Exalogic Elastic Cloud. By leveraging the Inifiniband Fabric in Exalogic, Coherence can now operate at up to 6x the speed on as little as half the hardware on an Exalogic box. This breakthrough is helping customers save money on their hardware costs while improving performance of their data grid. Here's a free resource available for you to explore this technology relationship further.For even more information on Coherence, attend our upcoming free virtual developer day on November 5th to see how developers can leverage Coherence in their everyday tasks.

• Ubuntu won't load properly all of a sudden

  - by Peter Raeves

  This has been the second time this has happened, but when I booted this morning my hardware wasn't detected anymore. I see both screens pop up as normal, choose Ubuntu 14.04 in the grub list and from that point onwards none of the following hardware seems to be used: VGA, DVI-D, USB, Audio jacks. This has happened before, but at that time, I still had one screen left, so I could navigate through the (non-USB) keyboard and how weird this may sound, but from the moment I opened Windows in vmware, all of my hardware started working again. This was a few weeks ago, but the same seems to have happened again. This time I can't use that little hack though, since now Ubuntu stops using both screens. My hardware is all detected, Ubuntu just doesn't want to use it somehow. Did anybody else encounter this and how did they solve this?

• How to open the terminal? (Mis-configured the profile)

  - by JiminP

  I am quite new to Ubuntu. (I started to use Ubuntu about a year ago, but I don't know how to use things like terminal well. All I used by console was easy things like ls or cd, to use gcc.) Today, I found 'profile' property of the terminal, and I created a new profile. Then, I changed some properties like font color and opacity. Soon, I found something like 'command', and for test, I set that to ls. I closed and re-opened the terminal. However, the terminal terminates right after it appeared. I soon remembered that there was option like 'close right after the command is executed'. Therefore, I can't use Gnome Terminal D: ... I found Konsole at Ubuntu software center, but that's just not my style (especially cursor, its position is little weird...). Question : How to change the profile of Gnome Terminal, without opening it?

• Programming C++ using Qt4

  - by DaGhostman Dimitrov

  Hey guys I am really new to the C++ programing I have a little knowledge in C and a bit more in C++, but I do not know them enough to call myself a programmer. I am working as a PHP Web Developer I like being a crafts man and creating things so that is the reason to combine the programming with web development. I think that I could really benefit from both of them and so... My question is: Is it a good Idea to learn C++ with Qt or not? Can you give me pros and cons of both? Note: I do not want to become a programmer and give up the web development I want to combine them both.

• XNA Monogame GameState Management not deserilaizing

  - by Pectus Excavatum

  I am having some trouble serializing/deserializing in a little game I am doing to teach myself monogame. Basically, I am using the gamestatemnanagement resources common to monogame (screen manager etc). Then I am serializing my screen manager component and all associated screens in the OnDeactivated method: protected override void OnDeactivated(Object sender, EventArgs args) { foreach (GameplayScreen screen in mScreenManager.GetScreens()) { DataManager.SaveData(screen.Level.LevelData); } mScreenManager.SerializeState(); } The Save data bit is to do with something else. Then I then override OnActivated to de serialize protected override void OnActivated(Object sender, EventArgs args) { //System.Diagnostics.Debug.WriteLine("here activating"); mScreenManager.DeserializeState(); } However, when this runs it just loads a blank screen - it goes into the game initialize and the game draw method, but doesnt go down into the screens initialize or draw methods. I have no idea why this might be - any help would be greatly appreciated. I am not the only one who has encountered this - I found this post also - https://monogame.codeplex.com/discussions/391117

• Function names - "standardized" prefixes

  - by dnsmkl

  Imagine you have such routines /*just do X. Fail if any precondition is not met*/ doX() /*take care of preconditions and then do X*/ takeCareOfPreconditionsCheckIfNeededAtAllAndThenDoX() A little bit more concrete example: /*create directory. Most probably fail with error if any precondition is not met (folder already exists, parent does not exists)*/ createDirectory(path_name) /*take care of preconditions (creates full path till folder if needed, checks if not exists yet) and then creates the directory*/ CheckIfNotExistsYet_CreateDirectory_andFullPathIfNeeded(path_name) How do you name such routines, so it would be clear what does what? I have come to some my own "convetion" like: naiveCreateDirectory, ForceDirectoryExists, ... But I imagine this is very standard situation. Maybe there already exists some norms/convetions for this?

• Is it only possible to display 64k vertices on the monitor with 16bit?

  - by Aufziehvogel

  I did the first 3D tutorial over at riemers.net and stumbled upon that my graphic card only supports Shader 2.0 (Reach profile in XNA) which means I can only use Int16 to store the indices (triangle to vertex). This means that I can only store 2^16 = 65536 vertices. Also I read on the internet that you should prefer 16-bit over 32-bit because not all hardware (like mine) does support 32-bit. Yet, I am wondering: Do really all game scenes get along with only so little vertices? I though already faces of people used a lot of polygons (which are made up of vertices?). It’s not relevant for me yet, but I am interested: Do game scenes use only 65536 vertices? Do you use some trade-off to display more (e.g. 64k in GPU buffer rest on RAM) Is there some method to get more into the GPU buffer? I already read on some other posts that there seems to be a limit of 64k per mesh too, so maybe you can compact stuff to meshes?

• Writing drivers for a printer?

  - by user828584

  My goal is to be able to fax 20 page pdf documents for free. I've looked online, and there are some free fax services, but all of them have their limits. I do have an old fax machine, but the documents that need to be faxed are on the computer, and to print them would be far from free. Unfortunately, the only way to send a fax with the machine is by scanning it. What's strange is that it can scan to the computer and print from it, but it won't fax from it... :(. Is it possible to write something (preferably C#, but it's going to take some learning anyway) that will allow me to send a fax from the computer? I have very little software experience, and none in anything like this, so I have no idea where to start. If it is possible, where can I find all the information needed to write the program?

• Java on Ubuntu server 12.04?

  - by Sean Dunwoody

  I'm a little confused at the moment. My back story in short, is that I'm trying to set up a Minecraft server on an Ubuntu server I've recently set up, obviously to do this I needed Java, but after googling for a short while I wasn't entirely sure whether it is possible (or legal?) to do so in Ubuntu 12.04 due to licensing type issues - so I installed open JDK instead which appears not to work properly with the Minecraft server software (I half expected this) I'm now considering uninstalling open JDK and instead trying to get proper Java on there instead, my question is, is this possible? Is it Legal? And if so how do I go about doing it? Because I'm finding it very difficult to find any instructions on how to do so for 12.04 . . .

• Huge company wants my domain name

  - by Charles Marsh

  Not sure if this is the right place to ask but I'll give it a go. I simply require a little advice; A very large hosted e-commerce platform emailed me a while back and basically asked me to transfer my domain name to them. They made no offer but simply said 'why not change your domain to xx - xx instaead of xxxx' Not they own all the equivalent names in .com, .org all of them apart from my .co.uk I am a registered partner of theirs and my website is a portfolio of all my themes but I also get a lot of enquires through it. I had heard rumors this company is opening an office in the UK! I'm right in thinking I shouldn't just roll over right? I've put some much effort in to SEO and building my reputation... I can't just give it up surly?

• Dependant care account, is it working for you?

  - by heshamelsaghir

  Well, NO.  my little three years old boys are very sick so I need to get them out of the day care.  they keep getting ear infection so bad even the ear tube is not working.  so, now do I give my $5000.00 to the government as a donation or keep my kids in the day care and loose the hearing?  what is going on? I was told I can change this Dependant care account ONLY in the case of a life change!  well, is not this a life change?  when a member of the family is very sick and has to go through an operation "Ear Tube", the operation does not work and keeps getting sick.  Would not this be a life change?

• Is there a well grounded theory on backward and forward compatibility of formats, languages, grammars and vocabularies?

  - by Breton

  I have a friend who has the specific problem of building a case against the use of a custom HTML <wrapper> tag in some site's markup. Now, intuitively we can answer that use of such a tag is risky, as future HTML specs may define a wrapper tag with semantics that conflict with its use on the site. We can also appeal to a particular section of the HTML5 spec which also recommends against the use of custom tags for this reason. And while I agree with the conclusion, I find these arguments a little on the weak side, on their own. Is there some well grounded and proven theory in computer science from which we can derive this conclusion? Have programming language theorists created proofs about the properties of vocabulary versioning, or some such thing?

• Attributes and Behaviours in game object design

  - by Brukwa

  Recently I have read interesting slides about game object design written by Marcin Chady Theory and Practice of the Game Object Component Architecture. I have prototyped quick sample that utilize all Attributes\Behaviour idea with some sample data. Now I have faced a little problem when I added a RenderingSystem to my prototype application. I have created an object with RenderBehaviour which listens for messages (OnMessage function) like MovedObject in order to mark them as invalid and in OnUpdate pass I am inserting a new renderable object to rederer queue. I have noticed that rendering updates should be the last thing made in single frame and this causes RenderBehaviour to depend on any other Behaviour that changes object position (i.ex. PhysicsSystem and PhysicsBehaviour). I am not even sure if I am doing this the way it should be. Do you have any clues that might put me on the right track?

• Bumblebee optirun appears to depend on Intel

  - by user206398

  I have a Lenovo T420 with Intel and Nvidia graphics. On upgrade to Ubuntu Saucy, I had to purge and reinstall bumblebee-nvidia to get beyond optirun failing to find a GPU driver. Now, "optirun glxgears" and "optirun sol" succeed, but optirun fails on 2 Virtual Life viewers that it supported in the past, Cool VL (CoolVLViewer-1.26.8.34-Linux-x86) and Imprudence (Imprudence 1.4.0 beta2). In both cases, the error output is huge, but it starts with libGL error: failed to load driver: i965 and libGL error: failed to load driver: swrast From the little I can discover, i965 is an Intel graphics driver, which should not be invoked at all. I haven't found any information about swrast. I suspect that some of the X configuration associated with Bumblebee has some Intel dependence that is invoked on certain library calls, but not others. I haven't discovered any definite information on this line. The Cool VL Viewer runs without optirun, but complains about the insufficiency of the Intel graphics.

• returning null vs returning zero, which would be better?

  - by Dark Star1

  I inherited a project that I am managing and having to maintain pending the redevelopment of the code base. At the moment I am being tasked with adding little feature all over the place and have gotten into the habit of returning null instead of zero in parts of the code where I am working on. The problem is we have a client that is using this code and parts of code that require data from my implemented features recieve a null and dump the stack trace in UI. I would like to avoid this entirely from my input but without the nullPointer exceptions there's the potential that errors would be introduced into the client's data which may go un-noticed. Usually I would have come up with my own error notification system but I have never inherited a project before. so I am unsure whether to continue down this path. I still believe that the stack dump is preferable to un-noticed data corruption/inaccuracies.

• Mic not working on Lenovo G470

  - by Caveman

  I used a Lenovo G470 laptop (Core i5 2410M processor, AMD Radeon 6370M and 2GB DDR3 RAM) and I installed Ubuntu 12.04. I can't get the microphone to work. I encountered this type of issue before in my old Acer Aspire One with Ubuntu 10.04/10.10, and installing PulseAudio Volume Control and tweaking a little solves the problem. I tried the same solution to no avail in 12.04. I tried entering the alsa in terminal and my mic is not detected there. Does anybody encountered a similar problem? Any help will be greatly appreciated.

• Is an in-app purchase required to unlock game in order to bypass pirating acceptable?

  - by digitaljoel

  I'm considering writing a mobile game and looking at distribution. The game will have a server requirement, which means I will have to pay for bandwidth, hosting, processor time, etc. Because of that I'll need to make at least a little money off this thing. According to the press piracy is rampant in the android community. To get around this, I'm thinking of implementing a simple model where the game is free, perhaps allowing play for X number of turns or something, and then requiring an in-app purchase to continue to play. I would clearly explain this in the app description, and the in-app purchase would be managed per account so it would be linked to your google play account so you wouldn't have to re-purchase every time you get a new device. Would gamers accept this model or see it as unreasonable?

• seo value of duplicating content externally

  - by Don

  I run a website that includes a blog which was hand-coded by myself and is hosted on the same domain. My partner in this endeavour thinks it would be a good idea to open up a blogger/wordpress blog and duplicate the on-site blog on this off-site blog. AFAIK the main reason for doing this is the SEO benefits of the inbound links that this off-site blog will create. I think this is a bad idea, because: Effectively what we're doing is creating a (very small scale) link farm We're more likely to be punished than rewarded (in SEO terms) for duplicating our content across domains This introduces a problem of synchronising our content across domains. For example, if a blog post is edited on the on-site blog, then ideally the off-site blog should be similarly updated. I know very little about SEO, so would be interested to hear what more informed readers have to say.

• Does putting types/functions inside namespace make compiler's parsing work easy?

  - by iammilind

  Retaining the names inside namespace will make compiler work less stressful!? For example: // test.cpp #include</*iostream,vector,string,map*/> class vec { /* ... */ }; Take 2 scenarios of main(): // scenario-1 using namespace std; // comment this line for scenario-2 int main () { vec obj; } For scenario-1 where using namespace std;, several type names from namespace std will come into global scope. Thus compiler will have to check against vec if any of the type is colliding with it. If it does then generate error. In scenario-2 where there is no using namespace, compiler just have to check vec with std, because that's the only symbol in global scope. I am interested to know that, shouldn't it make the compiler little faster ?

• Cannot resume from hibernate (s2disk)

  - by hwjp

  I seem to be able to hibernate OK using s2disk, but when I switch the laptop back on, it seems to hang half-way through the "resuming" menu. The splash screen looks healthy, it seems to be trying to resume from the correct disk, but it hangs about half-way through, with three little pips. One great help would be - where can I find the logs, and how do I get more verbose ones? There is some info in /var/log/pm-suspend.log, but that all seems fine, just lots of hibernate: success messages... How do I switch on more verbose logging in s2disk? And what about the resume process, where are the logs for that, and how can I make them more detailed? Background: the standard Ubuntu hibernate wouldn't work, so I've install uswusp and its associated tools - s2disk etc. That initially made things worse, but a fair amount of fiddling with its config, my swap size and so on seem to have got it at least seemingly successfully suspending...

• Azure Florida Association: Modern Architecture for Elastic Azure Applications

  - by Herve Roggero

  Join us on November 28th at 7PM, US Eastern Time, to hear Zachary Gramana talk about elastic scale on Windows Azure. REGISTER HERE: https://www3.gotomeeting.com/register/657038102 Description: Building horizontally scalable applications can be challenging. If you face the need to rapidly scale or adjust to high load variations, then you are left with little choice. Azure provides a fantastic platform for building elastic applications. Combined with recent advances in browser capabilities, some older architectural patterns have become relevant again. We will dust off one of them, the client-server architecture, and show how we can use its modern incarnation to bypass a class of problems normally encountered with distributed ASP.NET applications.

• Does tweeting 9 to 5 hurt job applicants?

  - by evadeflow

  If you were looking into a job applicant's background and discovered that he or she has 1200 followers on Twitter and averages 50 tweets per day (more than half of which are during business hours), would it affect your hiring decision? How and why? Personally, I'd be a little worried about the candidate's ability to focus on the job at hand if they're constantly checking in with their 'tweeps' thoughout the day. In non-tech jobs, a lot of companies simply block Twitter as an irrelevant distraction. But it can be a useful resource---to programmers in particular. I just wonder how much is too much. At what point does it become a red flag?

• After installing Windows XP I can't boot into Ubuntu 12.04 LTS

  - by Osama

  I know that this issue may have been happened to many people and answered many times. For some reason, I had to install Windows XP beside Ubuntu 12.04 LTS. Once I did that, I'm no longer able to log on to my Ubuntu. The booting list screen doesn't show up. I tried some ways to fix that, one was to try Boot Repair (of course after opening Ubuntu live from a USB), however, the program didn't open after the installation had finished !! So how can I fix that? I hope you guys stick a little with my problem until it is solved

• Should I understand SVN before I jump to GIT?

  - by John Isaacks

  I work in a department where no one has ever used source control before, including myself. I am trying to push the concept. I have spent a little while researching SVN. I some basics learned. I can Create/update/checkout/commit with command line and from Tortoise. I am starting to learn how to tag and branch but still confused a lot about conflicts between branches and trunk etc. I am still learning, but I do not have a physical person who can show me anything. Its all from books/tutorials and trial and error. From what I have read online it seems like git is the better thing to know, but its also more complicated. I don't want to overwhelm myself. Should I continue to master svn before moving to git or would I be wiser to just jump to git now? Are there pros and cons to both approaches?
