  • Is a big name computer science degree worth the cost?

    - by Serplat
    I'm currently in High School and trying to look into what I want to do after I graduate. I know that I will be going to college, and that I want a degree in Computer Science, however, I'm not entirely sure where I want to go (I haven't started the application process yet). I already have built up a decent amount of experience in programming (over the summers I have been hired to program at a local university), and I'm pretty capable of teaching myself most of the material I've come across through either books or web documentation. I'm interested in whether it is worth it to get a degree from a major, big-name computer science university for $50,000 each year, as opposed to going to a local state school for only $20,000. For my Bachelor's degree alone, this would be $120,000 more than the state school. I've also heard that where you get your Bachelor's doesn't matter much if you plan to get a Master's degree. Many people recommend going somewhere like a state school for your Bachelor's, and then try to get into a more major school for your Master's. Has anybody found any truth in this? Basically, is going to a big name computer science school for a Bachelor's degree really worth the added expense?

  • How do I configure NTLM authentication in Firefox on Linux?

    - by tolomea
    Our IT department have NTLM deployed through the intranet servers. I've set network.automatic-ntlm-auth.trusted-uris value in Firefox on some of the Windows machines and that works fine. However setting it in Firefox on the Linux machines is not working. This doesn't surprise me at all, I've no notion of where Firefox on Linux is supposed to get the authentication details from. So how is this process supposed to work? what bits of config / infrastructure am I missing?

  • Suphp connection reset by peer in error logs

    - by trante
    In my Linux server's logs I have this record nearly every 5 minutes. I couldn't find the reason for two weeks and I would be very happy if you can recommend me a way to diagnose the problem. It is inside error_log file. I use php 5.3.8 and litespeed. 2012-09-03 16:01:28.399 [INFO] [95.7.223.91:63814-0#APVH_example.com] connection to [/tmp/lshttpd/ APVH_example.com_Suphp.sock. 781] on request #151, confirmed, 0, associated process: 845244, running: 0, error: Connection reset by peer!

  • Do I really need Microsoft Updates?

    - by Tony Wong
    When I install a fresh copy of Windows XP Home (I bought it from the store.. not a copy), my PC rocks like lightening speed. But when I start installing all the updates, patches & less .NET 4.0 client (as the .NET 4.0 Client seems to bring machine to slow crawl). The PC starts to slow down.. like there are more resources to watch or something is happening in the background. So could I not get away with an awesome virus protector and an awesome firewall set-up and avoid all the patches? The machine I have is a quad 4, 4 GB RAM and 2.3 GHz process. Tons of room and the machine can run several applications at one time.. but when the updates happen.. it's s-l-o-w!

  • Mac OS X: pushing all traffic through a VMWare VM

    - by bj99
    I want to set up an Astaro (Sophos) UTM in a Virtual Machine. The Setup should be at the end the following: Cable Modem (one IP adress) | [Ethernet] Sophos UTM (running as VM [VMWare Fusion 5] on the MacMini) | [WIFI] Airport Express v2 (for sharing Local Network to wireless and wired clients) 1)| [WIFI] 2)| [Ethernet over Thunderbolt Ethernet Adapter]* Clients MacMini (Local File Server) *To have the Mini also protected behind the UTM So the setup process for the UTM works fine, but then the problems start: I just have one external IP (from my cable modem provider)== So if I put the VM in briged mode my Internet connection drops, because the MacMini also has its IP adress. If I put the VM to NAT mode the Mini itself is not protected by the UTM So: is there a way to hide the en0 interface(Ethernet) and the en1 interface (Wifi) from the MacMini, so that they not even appear in System Preferences Network section but are available to the VM? That way the Mini must connect to the en2 interface (Thunderbolt adapter) to make any Internet/LAN connection and I just use the given single IP from the Cable Modem. Thaks for any suggestions...

  • .NET Dependency Management Systems

    - by StriplingWarrior
    I have some .NET projects that are starting to get large enough to merit looking into Dependency Management solutions, so we don't have to copy binaries from one project to another. Here's what I've found so far: NPanday is based on a port of Maven. I can't tell how recently it was worked on, but the last release was in May 2011. NuGet seems to be under active development, and it appears to have support directly from Microsoft. Some people complained that it "only addresses dependency resolution," but I don't know what else it should address, or whether it has added more features since that point. It does appear to have recently added the ability to import binaries as part of the build process so we don't have to commit them to our repositories. Refix appears to still be in Beta, after having received no attention since Sept 2011. Would somebody with recent experience using any of these dependency management tools (or any others that work well) share your experience? Is NuGet mature enough to use it for dependency management? If not, what does it lack?

  • Allow READ access to local folders in 2003SBS AD

    - by Dan M.
    Have a SBS2003 client with a mess of a domain that is in process of being cleaned. But, for the life of me I cannot find a setting that will allow write access to the local hard disk for domain users with redirected profiles(to the server). This is needed only for one program that will not follow a symbolic link to the network path, instead it seems to be hard coded to the %appdata% folder but only on the c: drive.... So question is how can I allow "Domain users" write access to the local %appdata% directory? I have tried setting it manually on a machine but it kept resetting to RO no matter how many times I tried. Everytime I would uncheck the RO property it would reset sometime right after i hit OK. Thanks in advance! Dan

  • Using EC2 instance as main development platform

    - by David
    My problem I am working as a consultant for various companies. Each company provides me with a laptop where with their software on and I also have my own where I have my development environment. I tend to buy a new laptop every second year and find myself spending lots of time configuring and installing software. I also sometimes spend a lot of time waiting for my laptop to process things. To solve all these issues, I am now considering using EC2 (running windows instances) as my main development platform and just access this from any PC I happen to be at. I calculated that running the High-CPU On-Demand Instances (medium) for 8 hours a day for a year costs me 580$, which is acceptable. I imagine that when I approach the workplace each day, I will make a single click my phone to fire up the instance, so it is ready when I get to work. I should have different icons on my phone to fire up the various instance types. The same software should of course automatically be loaded on the various hardware (sometimes I would even need their instance with 68.4 GB of memory). Another advantage is that if I am having a specific problem with my instance, I could fire up another instance and have someone look into the problem and update the image. My question: Does anyone have experience with such a setup on EC2? What kind of problems do you forsee?

  • Why does Windows share permissions change file permissions?

    - by Andrew Rump
    When you create a (file system) share (on windows 2008R2) with access for specific users does it changes the access rights to the files to match the access rights to the share? We just killed our intranet web site when sharing the INetPub folder (to a few specified users). It removed the file access rights for authenticated users, i.e., the user could not log in using single signon (using IE & AD)! Could someone please tell me why it behaves like this? We now have to reapply the access right every time we change the users in the share killing the site in the process every time!

  • fdisk -l only displays boot partition

    - by Franklin
    I have a SAN, and it's able to read and write to the 50TB RAID just fine, but when I run fdisk -l it only lists the boot partition of the SAN server, and doesn't display anything about the other partitions on the RAID. I've also tried using parted -l with the same result. Now when I type mount it shows that the partitions are mounted just fine. I've never seen this happen. The box is running Openfiler 2.3 (I know it's old, we're in the process of upgrading all our old equipment). We have another SAN that's configured almost identically, and it's able to display the partition info with either of the two commands I mentioned above.

  • Experienced programmer, beginner at web design, tools for effective maintainable web design? [closed]

    - by Clinton
    I do quite a bit of programming in my work, which I'm comfortable with, but recently I've being trying to do some web-design for non-work related reasons. I've got a Drupal site up and running, and added some content. But they all look fairly basic. Header with some content. It doesn't look particularly polished. Anyway, as an example, what I wanted to do was make some "bubbles", each with some text in them. From a programmers point of view, say: bubble(question_text, answer_text) might expand to a box with some border, with "Question: " + question_text then "Answer: " + answer_text. Of course I'd have lots of these bubbles, but I'd like to change their look and feel in one place, so simple HTML would be a maintainable nightmare. I also want to lay them out on the screen in some fashion. I was thinking a mixture of javascript and CSS, or possibly use PHP which Drupal uses. On the other hand, I fear I might be taking a 1990s approach to this, and that there's actually tools available now that make this process a lot easier. I'm just wondering what the best approach to this sort of task is? Should I be using offline web design software and copying the code to Drupal, and if so, any recommendations? I'm sorry if my question is a bit vague, because I'm not really sure what question I should be asking. I'd appreciate if you answer and comment, and I'll try my best to be more specific as I understand more.

  • Is it possible to make Ctrl+C as responsive as Ctrl+Break in the Windows 7 console?

    - by Peter Graham
    Is it possible to make Ctrl+C act like Ctrl+Break in the Windows 7 cmd.exe console? By default Ctrl+C seems to only send a signal the next time the input buffer is read, where Ctrl+Break sends a signal immediately. This makes Ctrl+C useless for ending processes because when I want to end a process I want to end it immediately. I'm using Ctrl+Break for now but it's far harder to type. It looks like in DOS you can add BREAK=ON to CONFIG.SYS to achieve this, but not in Windows 7?

  • Too many heap subpools might break the upgrade

    - by Mike Dietrich
    Recently one of our new upcoming Oracle Database 11.2 reference customers did upgrade their production database - a huge EBS system - from Oracle 9.2.0.8 to Oracle Database 11.2.0.2. They've tested very well, we've optimized the upgrade process, the recompilation timings etc.  But once the live upgrade was done it did fail in the JAVA component piece with this error: begin if initjvmaux.startstep('CREATE_JAVA_SYSTEM') then * ORA-29553: classw in use: SYS.javax/mail/folder ORA-06512: at "SYS.INITJVMAUX", line 23 ORA-06512: at line 5 Support diagnosis was pretty quick - and refered to:Bug 10165223 - ORA-29553: class in use: sys.javax/mail/folder during database upgrade But how could this happen? Actually I don't know as we have used the same init.ora setup on test and production. The only difference: the prod system has more CPUs and RAM. Anyway, the bug names as workarounds to either decrease the SGA to less than 1GB or decrease the number of heap subpools to 1. Finally this query did help to diagnose the number of heap subpools: select count(distinct kghluidx) num_subpools from x$kghlu where kghlushrpool = 1; The result was 2 - so we did run the upgrade now with this parameter set: _kghdsidx_count=1 And finally it did work well. One sad thing:After the upgrade did fail Support did recommend to restore the whole database - which took an additional 3-4 hours. As the ORACLE SERVER component has been already upgraded successfully at the stage where the error did happen it would have been fine to go on with the manual upgrade and start catupgrd.sql script. It would have been detected that the ORACLE SERVER is upgraded already and just picked up the non-upgraded components. The good news:Finally I had one extra slide to add to our workshop presentation

  • What determines which Javascript functions are blocking vs non-blocking?

    - by Sean
    I have been doing web-based Javascript (vanilla JS, jQuery, Backbone, etc.) for a few years now, and recently I've been doing some work with Node.js. It took me a while to get the hang of "non-blocking" programming, but I've now gotten used to using callbacks for IO operations and whatnot. I understand that Javascript is single-threaded by nature. I understand the concept of the Node "event queue". What I DON'T understand is what determines whether an individual javascript operation is "blocking" vs. "non-blocking". How do I know which operations I can depend on to produce an output synchronously for me to use in later code, and which ones I'll need to pass callbacks to so I can process the output after the initial operation has completed? Is there a list of Javascript functions somewhere that are asynchronous/non-blocking, and a list of ones that are synchronous/blocking? What is preventing my Javascript app from being one giant race condition? I know that operations that take a long time, like IO operations in Node and AJAX operations on the web, require them to be asynchronous and therefore use callbacks - but who is determining what qualifies as "a long time"? Is there some sort of trigger within these operations that removes them from the normal "event queue"? If not, what makes them different from simple operations like assigning values to variables or looping through arrays, which it seems we can depend on to finish in a synchronous manner? Perhaps I'm not even thinking of this correctly - hoping someone can set me straight. Thanks!

Increasingly, DRM is also being utilized by Oracle customers for reference data management, an emerging solution space that deserves some explanation. What is reference data? Reference data is a close cousin of master data. While master data may be more rapidly changing, requires consensus building across stakeholders and lends structure to business transactions, reference data is simpler, more slowly changing, but has semantic content that is used to categorize or group other information assets – including master data – and give them contextual value. The following table contains an illustrative list of examples of reference data by type. Reference data types may include types and codes, business taxonomies, complex relationships & cross-domain mappings or standards. Types & Codes Taxonomies Relationships / Mappings Standards Transaction Codes Industry Classification Categories and Codes, e.g., North America Industry Classification System (NAICS) Product / Segment; Product / Geo Calendars (e.g., Gregorian, Fiscal, Manufacturing, Retail, ISO8601) Lookup Tables (e.g., Gender, Marital Status, etc.) Product Categories City à State à Postal Codes Currency Codes (e.g., ISO) Status Codes Sales Territories (e.g., Geo, Industry Verticals, Named Accounts, Federal/State/Local/Defense) Customer / Market Segment; Business Unit / Channel Country Codes (e.g., ISO 3166, UN) Role Codes Market Segments Country Codes / Currency Codes / Financial Accounts Date/Time, Time Zones (e.g., ISO 8601) Domain Values Universal Standard Products and Services Classification (UNSPSC), eCl@ss International Classification of Diseases (ICD) e.g., ICD9 à IC10 mappings Tax Rates Why manage reference data? Reference data carries contextual value and meaning and therefore its use can drive business logic that helps execute a business process, create a desired application behavior or provide meaningful segmentation to analyze transaction data. Further, mapping reference data often requires human judgment. Sample Use Cases of Reference Data Management Healthcare: Diagnostic Codes The reference data challenges in the healthcare industry offer a case in point. Part of being HIPAA compliant requires medical practitioners to transition diagnosis codes from ICD-9 to ICD-10, a medical coding scheme used to classify diseases, signs and symptoms, causes, etc. The transition to ICD-10 has a significant impact on business processes, procedures, contracts, and IT systems. Since both code sets ICD-9 and ICD-10 offer diagnosis codes of very different levels of granularity, human judgment is required to map ICD-9 codes to ICD-10. The process requires collaboration and consensus building among stakeholders much in the same way as does master data management. Moreover, to build reports to understand utilization, frequency and quality of diagnoses, medical practitioners may need to “cross-walk” mappings -- either forward to ICD-10 or backwards to ICD-9 depending upon the reporting time horizon. Spend Management: Product, Service & Supplier Codes Similarly, as an enterprise looks to rationalize suppliers and leverage their spend, conforming supplier codes, as well as product and service codes requires supporting multiple classification schemes that may include industry standards (e.g., UNSPSC, eCl@ss) or enterprise taxonomies. Aberdeen Group estimates that 90% of companies rely on spreadsheets and manual reviews to aggregate, classify and analyze spend data, and that data management activities account for 12-15% of the sourcing cycle and consume 30-50% of a commodity manager’s time. Creating a common map across the extended enterprise to rationalize codes across procurement, accounts payable, general ledger, credit card, procurement card (P-card) as well as ACH and bank systems can cut sourcing costs, improve compliance, lower inventory stock, and free up talent to focus on value added tasks. Specialty Finance: Point of Sales Transaction Codes and Product Codes In the specialty finance industry, enterprises are confronted with usury laws – governed at the state and local level – that regulate financial product innovation as it relates to consumer loans, check cashing and pawn lending. To comply, it is important to demonstrate that transactions booked at the point of sale are posted against valid product codes that were on offer at the time of booking the sale. Since new products are being released at a steady stream, it is important to ensure timely and accurate mapping of point-of-sale transaction codes with the appropriate product and GL codes to comply with the changing regulations. Multi-National Companies: Industry Classification Schemes As companies grow and expand across geographies, a typical challenge they encounter with reference data represents reconciling various versions of industry classification schemes in use across nations. While the United States, Mexico and Canada conform to the North American Industry Classification System (NAICS) standard, European Union countries choose different variants of the NACE industry classification scheme. Multi-national companies must manage the individual national NACE schemes and reconcile the differences across countries. Enterprises must invest in a reference data change management application to address the challenge of distributing reference data changes to downstream applications and assess which applications were impacted by a given change.

  • How to fix /etc/ folder on Mac OS X

  • Where does the information shown by OS X Terminal 'Display all commands' feature come from?

    - by Sergio Acosta
    I just learned that if you hit and hold ESC while on the Mac Terminal, a prompt appears after a few seconds offering to show every command available on your system, including aliases, built-ins, and executables on your PATH. Soruce: http://www.mactricksandtips.com/2008/05/list-all-possible-terminal-commands.html However, the output is show through a more filter, and I cannot grep it or pipe it to another command. Does anyone know how this magic output is generated? Is it just generated on the fly by Terminal? Is there a bash command that can be called explicitly on the command line and get the same result? It is mostly curiosity, but I would love to be able to get the results as text I can post-process and not just browse on screen.

  • Languages on a resume: Is it better to put "C/C++" or "C, C++"?

    - by Kevin
    I'm graduating in a couple of weeks, and my resume (as expected) lists the languages that I've had experience with. Previously I've put "C/C++", however back then I didn't have that much experience with these two languages as I do now. Now that I've formally learned these two languages, it has become evident to me (and anyone who really knows these languages) that they are similar, and completely disimilar at the same time. Sure, most C code is compilable C++ code, but syntax and incorporation of library functions is pretty much where these similarities end. In most non-trivial problems, chances are that the desirable C++ solution will be different from the desirable C solution. My question: Will recruiters take note or care about whether you put "C/C++" as opposed to "C, C++"? Will they assume a lack of knowledge of the workings of either because of the inclusion of the first form, or perhaps see the inclusion of the second form as a potential "resume beefer" (listing them as 2 languages, instead of "one")? Furthermore, for jobs that you've applied to that were particularly interested in these two langauges, did the interview process include questions about the differences between C programming and C++ programming (so, about actual programming techniques, not only the extra paradigms in the latter)?

    I have created customized live cd of lubuntu and it is customized using uck. After burning the CDROM and using the cdrom for installation of same CD the installation works fine on HP desktop but it fails on Dell desktop. Here is the error. Can someone help to sort out this error. We are sorry; the installer crashed. After you close this window, we will allow you to file a bug report using the integrated bug reporting tool.

  • Bizarre SSH Problem - It won't even start

    - by thallium85
    I recently got Ubuntu 12.04 Precise, got it up and running with some MediaWiki software, static IP on the box and router and was able to access the main page even from a cell phone. Everything seemed great... Then I wanted to finally get rid of the monitor and keyboard and login remotely via SSH. I installed openssh-server, let everything point to port 22 for a test run and installed putty on my Windows XP machine. I got a connection refused. Went back and started checking the Ubuntu install itself... (I'm under root from this point on) $ sudo -s $ service ssh status ssh stop/waiting $ service ssh start ssh start/running, process 2212 $ service ssh status ssh stop/waiting Apparently ssh has stopped or is waiting for something.... $ ssh localhost ssh: connect to host localhost port 22: Connection refused I can't even connect to myself... I checked ufw (firewall) to see if port 22 is doing alright... $ sudo ufw status Status: active To Action From 22 ALLOW Anywhere 22/tcp ALLOW Anywhere 22 ALLOW Anywhere (v6) 22/tcp ALLOW Anywhere (v6) sshd_config shows only Port 22 Is ssh not using the right IP address at all? I just don't get what I did wrong here. When this is up and running I will def change the port number, but for now, I don't want to mess with the default install too much until a test run with putty is successful. Edit: Here are my sshd_config file and my ssh_config file. The command /usr/sbin/sshd -p 22 -D -d -e returns: /etc/ssh/sshd_config line 159: Subsystem 'sftp' already defined. Edit: @phoibus moving the sshd_config file and reinstalling did the trick! service ssh status the above command shows that ssh is now running and I am now able to log in from my windows xp computer remotely via putty. Thanks so much! I can now use my monitor for other things!

  • Entity system in Lua, communication with C++ and level editor. Need advice.

    - by Notbad
    Hi!, I know this is a really difficult subject. I have been reading a lot this days about Entity systems, etc... And now I'm ready to ask some questions (if you don't mind answering them) because I'm really messed. First of all, I have a 2D basic editor written in Qt, and I'm in the process of adding entitiy edition. I want the editor to be able to receive RTTI information from entities to change properties, create some logic being able to link published events to published actions (Ex:A level activate event throws a door open action), etc... Because all of this I guess my entity system should be written in scripting, in my case Lua. In the other hand I want to use a component based design for my entities, and here starts my questions: 1) Should I define my componentes en C++? If I do this en C++ won't I loose all the RTTI information I want for my editor?. In the other hand, I use box2d for physics, if I define all my components in script won't it be a lot of work to expose third party libs to lua? 2) Where should I place the messa system for my game engine? Lua? C++?. I'm tempted to just have C++ object to behave as servers, offering services to lua business logic. Things like physics system, rendering system, input system, World class, etc... And for all the other things, lua. Creation/Composition of entities based on components, game logic, etc... Could anyone give any insight on how to accomplish this? And what aproach is better?. Thanks in advance, HexDump.

  • Getting iTunes to play third party AAC files

    - by Redmastif
    I have a library filled with some old MP3 files and I'm in the process of changing them all to AAC for the better sound quality. Obviously I can't just create AAC versions of the files I already have because they would sound worse (lossy compression to converted to more lossy compression), so I'm going to their source and downloading them in a lossless form and using a third party to make them into AAC. Apparently iTunes will not handle AAC files that aren't made with iTunes. Is there a way around this? I've looked at third party programs and would be willing to use them, but since they all require the iTunes/iPod/iEverything driver, I don't know if they would still prevent my files or not. Also before you jump on my back about pirating, these files are from old CDs that I lost years ago. I paid for them. Thanks.
