• Useful training courses that aren't specific to a single technology

  - by Dave Turvey

  I have possibly the best problem in the world. I have about £1600 left in a training budget and I need to find something to spend it on. I can spend it on anything that could be considered training. Books, courses, conferences, etc. I would like to find a course that would benifit a software developer but is not about learning a specific programming technology. I don't really want to spend it on a technical training course. These topics are usually best learned with a good book and some trial and error. I have also already been on a general business/management training course and a PRINCE2 project management course. I am currently working on a project on my own so am responsible for communicating with the client, requirements gathering, project management, etc., as well as the coding. What training have you found useful outside the usual technical stuff? Has anyone done any business analysis courses? What were they like? Are there any courses on some of the practicalities of working with software, e.g. automated test and deployment strategies, handling technical support? I would prefer a course in the UK but I can travel if necessary.

• What version of SCO Open Server are guys using out there and on what hardware?

  - by Gath

  I have some old applications which are running on SCO Open Server 5.0.5, and i would love to move them to SCO Open Server 5.0.7 and on modern hardware(servers), currently am running SCO on old IBM PL 300 personal computer, on 92MB Memory, one processor, and it has been serving the clients pretty well. Now i have New Modern IBM xseries Servers and i would love to migrate the same applications to those new servers. Problem is, SCO 5.0.5 is unable to detect some of the hardware components in the new servers. I read somewhere that SCO 5.0.7 is able to detect the newer hardware even the USB ports etc. Is there anyone running SCO Openserver out there, and on what hardware architecture are they running on?

  Hi all, i got an EXC_BAD_ACCESS when i perform the last line of the function (webData). -(void)requestSoap{ NSString *requestUrl = @"http://www.website.com/webservice.php"; NSString *soapMessage = @"the soap message"; //website and soapmessage are valid in original code.

• Eclipse Plug-In Installation Issues

  - by Mudu

  Hi all I'm beginning to work with Eclipse for some Java development. I'm quite new to Eclipse, as I am a Visual Studio developer normally. I tried to install the CheckStyle Eclipse Plug-In and Subversive, using the Eclipse "Install new Software" feature. No errors, everything seems to have worked well. Clicking on "What software is already installed?" in the Install-dialogue shows me a list of installed plug-ins. Both Subversive and CheckStyle for Eclipse are listed. My only problem is that neither of them "work", that means I cannot see any new UI elements. According to the manual I have, I should see a new node "CheckStyle" in a project's properties. I haven't. I don't know exactly what Subversive looks like, but I'm sure there's a way to conveniently perform check-out operations etc. Manually copying the downloaded plug-in to the dropins-folder and restarting Eclipse subsequently does not help either. Is there a way to reliably find out whether there occurred any errors - I have no error message at all, what drives me crazy and makes the problem pretty difficult to describe/Google... Any help would be very cool! Cheers Matthias

• Out of memory Problem

  - by Sunil

  I'm running a C++ program in Ubuntu 10.04 (32-bit system architecture). If I calculate the amount of memory that my program uses, it comes up to 800MB. I have a 4GB RAM in place. But still before the program even finishes it throws an out of memory exception. Why is that happening ? Is it because of the structure of the memory or implementation problems or what could possibly trigger this issue ? I've had seen this problem quite a number of times before but never understood the reason behind it. Have any of you handled this case before ?

• TCP/IP- what is it exactly?

  - by OckhamsRazor

  I know that this question sounds stupid, but over all these years, I still have difficulty explaining TCP/IP to people. I don't completely get it myself, and even after reading up on it, the distinction is not very clear. What I get so far is that IP deals with networks while TCP involves delivery of messages over that network. I'm not totally convinced though. Also, they reside on different layers of the Internet architecture. Could anyone disambiguate this distinction using a simple analogy or examples? Also, I read this somewhere The difference is that TCP is responsible for the data delivery of a packet and IP is responsible for the logical addressing. In other words, IP obtains the address and TCP guarantees delivery of data to that address. Is this correct? Thanks for helping me out. One last thing- Where does the ethernet come in all of this?

• How to change MySQL data directory?

  - by Jonathan Frank

  I want to place my databases in another directory, so I can store them in an ESB (elastic block storage, just a fancy name for a virtualized harddisk) together with my web-apps and other persistent data. I have tried to walk through a tutorial at http://crashmag.net/change-the-default-mysql-data-directory-with-selinux-enabled. Everything seems fine until I type this command: # semanage fcontext -a -t mysqld_db_t "/srv/mysql(/.*)?" Then the command fails and tells me that mysqld_db_t is an invalid SELinux context even if the default MySQL data directory is labelled with this context. I am running Fedora 15 on Virtualbox (behaves like an ordinary x86-compatible box) and Amazon EC2 (based on Xen) so the tutorial should be compatible. It is also worth to mention that turning off SELinux globally or just for the MySQL process is not an option, because such a solution will decrease the security of the system if a hacker gains access to the system via the MySQL server. I have never seen this problem before I changed to the Redhat/Fedora architecture, so it could be a distribution specific issue. Any help is highly appreciated

• Increase application performance on Amazon AWS

  - by Honus Wagner

  I've got a client with an MVC v1 (.NET) application running on a micro instance. On this instance, I've got .NET, IIS 7.5, and MS SQL Server 2008 running to handle the application. The client has reported that it is taking nearly 10 seconds to process each request. Even loading the initial login page takes about that long, then logging in takes that long, etc etc. The currently running instance specs are as follows: 615 MB RAM Intel Xenon CPU E5430 @ 2.66GHz 2.78 GHz 64-Bit Is the memory availability the issue? or is it the processing power? I forsee two options: Change to a larget instance Set up a 2-tier architecture with two micro instances Which of these will give the application better performance? Thanks in advance.

• .NET Reference "Copy Local" True / Fasle Being Set Based on Contents of General Assembly

  - by D-Sect

  Hello All. First question for me here. We had a very interesting problem with a Win Forms project. It's been resolved. We know what happened, but we want to understand why it happened. This may help other people out in the future who have a similar problem. The WinForms project failed on 2 of our client's PCs. The error was an obscure kernel.dll error. The project ran fine on 3 other PCs. We found that a .DLL (log4net.dll - a very popular open-source logging library) was missing from our release folder. It was previously in our release folder. Why was it missing in this latest release? It was missing because I must have installed a program on my Dev box that used log4net.dll and it was added to the general assembly. When I checked the SLN's references for log4net.dll, they were changed to "copy local=FALSE". They must have changed automagicially because log4net.dll was present in my GAC. Here's where my question starts: Why did my reference for log4net.dll get changed from COPY LOCAL = TRUE to COPY LOCAL = FALSE? I suspect it's because it was added to my GAC by another program. How can we prevent this from happening again? As it stands now, if I install a piece of software that uses a common library and it adds it to my GAC, then my SLNs that REF that DLL will change from Copy Local TRUE to FALSE. Thank you so much. I hope this helps people out who have a piece of software that runs in some places, but not in others, when it used to run fine in ALL places.

• UEC - Can the Cluster Controller and Storage Controller be seperate systems?

  - by Jeremy Hajek

  My department is implementing an Ubuntu Enterprise Cloud. I have done the testing and am quite comfortable with the 4 pieces, CC/SC, CLC, WS, NC. Looking at various documents below it appears the the Storage Controller and Cluster Controller (eucalyptus-sc and eucalyptus-cc) are always installed on the same system. My question is this: can I install the storage controller and the cluster controller on separate systems? http://open.eucalyptus.com/wiki/EucalyptusAdvanced_v2.0 the picture indicates that cc and sc are two different machines http://www.canonical.com/sites/default/files/active/Whitepaper-UbuntuEnterpriseCloudArchitecture-v1.pdf P.10 1st paragraph uses the word "machine(s)" http://software.intel.com/file/31966 P. 8 indicates the same separate architecture BUT... https://help.ubuntu.com/community/UEC/PackageInstallSeparate indicates below that the SC and CC are to be on the same system.

• Multiple sendto() using UDP socket

  - by ereOn

  Hi, I have a network software which uses UDP to communicate with other instances of the same program. For different reasons, I must use UDP here. I recently had problems sending huge ammounts of data over UDP and had to implement a fragmentation system to split my messages into small data chunks. So far, it worked well but I now encounter an issue when I have to send a lot of data chunks. I have the following algorithm: Split message into small data chunks (around 1500 bytes) Iterate over the data chunks list and for each, send it using sendto() However, when I send a lot of data chunks, the receiver only gets the first 6 messages. Sometimes it misses the sixth and receives the seventh. It depends. Anyway, sendto() always indicates success. This always happen when I test my software over a loopback interface (127.0.0.1) but never over my LAN network. If I add something like std::cout << "test" << std::endl; between the sendto() then every frame is received. I am aware that UDP allows packet loss and that my frames might be loss for a lot of reasons and I suppose it has to do with the rate I am sending the data chunks at. What would be the right approach here ? Implementing some acknowledgement mechanism (just like TCP) seems overkill. Adding some arbitrary waiting time between the sendto() is ugly and will probably decrease performance. Increasing (if possible) the receiver UDP internal buffer ? I don't even know if this is possible. Something else ? I really need your advices here. Thank very much.

• Should I use an ssl terminator or just haproxy?

  - by Justin Meltzer

  I'm trying to figure out how to set up my architecture for a socket.io app that will require both https and wss connections. I've found many tutorials on the web suggesting that you use something like stud or stunnel in front of haproxy, which then routes your unencrypted traffic to your app. If I were to go this route, is it suggested that haproxy and the ssl terminator be on separate instances, or is it fine if they are on the same EC2 server instance? If I do not want to use a separate ssl terminator, could I use haproxy to terminate the ssl? Or instead would it be possible to proxy these https and wss connections to my application and have the node app terminate the ssl itself?

• How important is PhD research topic to getting a job?

  - by thornate

  EDIT: This has been closed and I realise that I may not have been specific enough with the original title. I ask two questions here: The general one (Does a PhD help get a job?) which has been asked elsewhere, and the specific one (Is it possible to get work outside of the specific research field?). Assume I've already decided going to do the phd. I'm just stressing about the research topic. Well, I'm one year out of university (Mechatronics engineering and Software Eng double bachelors), worked for a few months then got retrenched (yay economy!). It's looking less and less likely that I'll get a job worth having with the job market as it is, so I'm thinking about going back to uni to do a PhD. I figure that by the time I'm done, the job market will have improved and hopefully I'll have something on my resume that is more attractive than spending three years doing customer support for accounting software. So, my question is to people who've done PhD's. Would you say that they were worth the effort? How important is the research topic to future job-seeking success? The idea I have is a computer-sciencey/neural-networks/data-mining thing which I think is very interesting, but not a field I want to be in forever. My potential supervisor claims that employers don't care so much about the topic of the research but rather the peripheral skills that are developed through a PhD; time managment, self-restraint, planning and whatnot. How does this mesh with people's real world experience? I'd appreciate any advice before signing my life on the line for the next three years. See also: Should developers go to grad school? Best reason not to hire a PhD? How to find an entry-level job after you already have a graduate degree?

• Losing Session between Classic ASP and ASP.NET

  - by Aaron

  The company that I work for is making a transition between classic ASP programs and ASP.NET programs for our intranet software. Eventually, everything will be written in ASP.NET, but because of time constraints, there are still a number of programs that use classic ASP. To compensate we've written features that allow for redirects and autologins between classic ASP programs and ASP.NET programs. I've been starting to see a problem, though, with holding the session state for our ASP.NET software. If a user uses an ASP.NET program, then does work in a classic ASP program, then goes back to that ASP.NET program, often times, the user's authentication for the ASP.NET program is still in place, yet the user's session is lost, resulting in an error whenever a function is performed within the program. I'm trying to capture the loss of the session state in global.asax's Session_End event, which would redirect the user to the login page, but that hasn't worked. Has anyone else faced a similar issue with users moving back and forth between classic ASP and ASP.NET and losing sessions? Is that even my real issue here? It's the only thing that I can see as being a problem. Thanks for any help.

• Is the Cloud ready for an Enterprise Java web application? Seeking a JEE hosting advice.

  - by Jakub Holý

  Greetings to all the smart people around here! I'd like to ask whether it is feasible or a good idea at all to deploy a Java enterprise web application to a Cloud such as Amazon EC2. More exactly, I'm looking for infrastructure options for an application that shall handle few hundred users with long but neither CPU nor memory intensive sessions. I'm considering dedicated servers, virtual private servers (VPSs) and EC2. I've noticed that there is a project called JBoss Cloud so people are working on enabling such a deployment, on the other hand it doesn't seem to be mature yet and I'm not sure that the cloud is ready for this kind of applications, which differs from the typical cloud-based applications like Twitter. Would you recommend to deploy it to the cloud? What are the pros and cons? The application is a Java EE 5 web application whose main function is to enable users to compose their own customized Product by combining the available Parts. It uses stateless and stateful session beans and JPA for persistence of entities to a RDBMS and fetches information about Parts from the company's inventory system via a web service. Aside of external users it's used also by few internal ones, who are authenticated against the company's LDAP. The application should handle around 300-400 concurrent users building their product and should be reasonably scalable and available though these qualities are only of a medium importance at this stage. I've proposed an architecture consisting of a firewall (FW) and load balancer supporting sticky sessions and https (in the Cloud this would be replaced with EC2's Elastic Load Balancing service and FW on the app. servers, in a physical architecture the load-balancer would be a HW), then two physical clustered application servers combined with web servers (so that if one fails, a user doesn't loose his/her long built product) and finally a database server. The DB server would need a slave backup instance that can replace the master instance if it fails. This should provide reasonable availability and fault tolerance and provide good scalability as long as a single RDBMS can keep with the load, which should be OK for quite a while because most of the operations are done in the memory using a stateful bean and only occasionally stored or retrieved from the DB and the amount of data is low too. A problematic part could be the dependency on the remote inventory system webservice but with good caching of its outputs in the application it should be OK too. Unfortunately I've only vague idea of the system resources (memory size, number and speed of CPUs/cores) that such an "average Java EE application" for few hundred users needs. My rough and mostly unfounded estimate based on actual Amazon offerings is that 1.7GB and a single, 2-core "modern CPU" with speed around 2.5GHz (the High-CPU Medium Instance) should be sufficient for any of the two application servers (since we can handle higher load by provisioning more of them). Alternatively I would consider using the Large instance (64b, 7.5GB RAM, 2 cores at 1GHz) So my question is whether such a deployment to the cloud is technically and financially feasible or whether dedicated/VPS servers would be a better option and whether there are some real-world experiences with something similar. Thank you very much! /Jakub Holy PS: I've found the JBoss EAP in a Cloud Case Study that shows that it is possible to deploy a real-world Java EE application to the EC2 cloud but unfortunately there're no details regarding topology, instance types, or anything :-(

  i have a win 7 host machine and i'm running my vmware which is a win server machine. So i'm doing windows development work on my vmware. the source codes are in my win 7 machine which i access using a shared folder method. My only problem now is when my vmware connects to VPN to the deploy the codes, the folder gets disconnected. as i don't really understand the networking or the vmware architecture, what can i do so that i can share the folder from my win 7 host machine to my vmware without getting disconnected when i connect to VPN using my guest (win server) machine? please advise. stuck on vmware thanks

• VPN Network intermittantly fails to provide internet: What could be possible causes

  - by Jake M

  We have a small office with our own VPN setup. We occasionally experience failures in our internet connection where we cannot access the internet. Most of the time the internet connection will resume by itself(without me doing anything) after a period of time(10 mins). Would you be able to suggest possible causes of the connection failure so I can then go and run some tests? Our network architecture is like so: A 'Billion' brand router that is connected to the internet via phone cable and then connected to our Cisco Switch A Cisco Switch/Bus which is connected to all our office nodes, our external harddrive and also to our router as stated above. All connections are via ethernet cable A series of work computers(nodes) connected via ethernet cable to the Cisco switch. Our ISP is TPG Australia We have a Virtual Private Network All the ethernet cables are about 3 years old Do you think that the causes of our intermittant connection problems could be due to the following: Data collisions in the ethernet cables Old/Faulty ethernet cables Our ISP has bad service Can you think of any other causes of the problem?

• iPhone offline reading

  - by Andy

  Hi, first of all - I am quite new to iPhone App development (3 months). I am working for a software company that offers a content management system. Our customers are for the main part publishing houses for magazines. They use our software to write articles to their homepages. Now we want to offer iPhone Applications to go with our cms. What I have accomplished so far is an RSS reader that shows newly published articles in a list view. The user selects one article and is redirected to a specially formatted detail view of this article. The next step is to add offline reading capabilities. I have searched the internet up and down but couldn't find anything like a best practice for that. I get it that there are two possibilities in general: Store the contents of the uiwebview locally on the iPhone/iPad (including css, images, js and so on). There would be the need to rework the basic html to use the downloaded css, images and js. Also I would have to somehow edit hyperlinks to following pages in multipage articles - Sounds like a lot of work ;) Create a PDF on the server side and download that to the mobile device. Rework the RSS Source to point to the locally saved pdf instead of the website on the server. My question is - what is the better way to go? Are there any downsides for either of the possibilities? Are there other (simple ;)) ways to implement offline reading features? Are there possibly any howto's that I could've missed? Thanks y'all!

• How are you taking advantage of Multicore?

  - by tgamblin

  As someone in the world of HPC who came from the world of enterprise web development, I'm always curious to see how developers back in the "real world" are taking advantage of parallel computing. This is much more relevant now that all chips are going multicore, and it'll be even more relevant when there are thousands of cores on a chip instead of just a few. My questions are: How does this affect your software roadmap? I'm particularly interested in real stories about how multicore is affecting different software domains, so specify what kind of development you do in your answer (e.g. server side, client-side apps, scientific computing, etc). What are you doing with your existing code to take advantage of multicore machines, and what challenges have you faced? Are you using OpenMP, Erlang, Haskell, CUDA, TBB, UPC or something else? What do you plan to do as concurrency levels continue to increase, and how will you deal with hundreds or thousands of cores? If your domain doesn't easily benefit from parallel computation, then explaining why is interesting, too. Finally, I've framed this as a multicore question, but feel free to talk about other types of parallel computing. If you're porting part of your app to use MapReduce, or if MPI on large clusters is the paradigm for you, then definitely mention that, too. Update: If you do answer #5, mention whether you think things will change if there get to be more cores (100, 1000, etc) than you can feed with available memory bandwidth (seeing as how bandwidth is getting smaller and smaller per core). Can you still use the remaining cores for your application?

• page wide bread crumb bar as at apple.com/store

  - by punkish

  I want to build a (don't know what to call it other than) bread crumb bar at the top of the page, kinda like at http://store.apple.com/us/browse/home/shop_mac/software, y'know, at the top of the page, the horizontal, light grey bar that looks like so [home icon] | Shop Mac | Mac Software Help | Account | Cart Actually, I've got that bar working, with a curved, square left edge, the intermediate chevrons, and the curved, square right edge. So, my bar looks like so [ Home > Foo > Bar > Baz ] I have little graphics fragments that make up the [ and the and the ] and the middle parts. The only problem is, I want the right edge to be at the right edge of my page. So, the above bar should look like so [ Home > Foo > Bar > Baz ] I want to have a variable number of entries in my bread crumb bar... so, I could have "Home, Foo, Bar, Baz" or I could have "Home, Foo" or "Home, Foo, Bar, Baz, Qux" and so on. In other words, I want the right edge of my bar to be dynamically long enough to extend to the edge of my web page. Suggestions?

• How does ARM Cortex A8 compare with a modern x86 processor

  - by thomasrutter

  I was wondering how does a modern ARM chip based on ARM Cortex A8 compare, in clock-for-clock performance and capability, to a modern x86 chip such as a Core 2 Duo or Core i5? I realise due to the different instruction sets it'll depend heavily on what you're doing. To put it another way, rendering a web page in webkit on a 1GHz ARM Cortex A8 based chip should be about equivalent to doing in on a Core i5 at __ MHz? Update October 2013: Since I asked this question years ago it's become a lot more common, when reading about mobile devices, to see architecture-agnostic benchmarks that you can compare across platforms - for example, in-browser benchmarks like Sunspider in Webkit will run on just about anything and you see these in reviews all the time now. And there's things like Geekbench now.

• Plesk 9.2 vs. DotNetPanel

  - by Pai Gaudêncio

  Howdy, Anyone with experience on using both control panels can tell me which one is better suited to run on a windows shared hosting account? I have the option of choosing one of them for my shared hosting account. The web hosting guys (MochaHost) say that DotNetPanel (DNP) is better than Plesk (more features, newer architecture, faster), but looking at the DNP interface I honestly can't say that I agree with them. The big advantage of DNP over Plesk for me is the fact that I can only run .Net 4.0 using DNP (Plesk doesn't support .Net 4.0 yet, as the tech support told me). Thanks

• Debugging MinGW program with gdb on Windows, not terminating at assert failure

  - by devil

  How do I set up gdb on window so that it does not allow a program with assertion failure to terminate? I intend to check the stack trace and variables in the program. For example, running this test.cpp program compiled with MinGW 'g++ -g test.cpp -o test' in gdb: #include <cassert> int main(int argc, char ** argv) { assert(1==2); return 0; } Gives: $ gdb test.exe GNU gdb 6.8 Copyright (C) 2008 Free Software Foundation, Inc.

Assertion failed: 1==2, file test.cpp, line 2 This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. Program exited with code 03. (gdb) I would like to be able to stop the program from terminating immediately, like how Visual Studio's debugger and gdb on Linux does it. I have done a search and found some stuff on trapping signals but I can't seem to find a good post on how to set up gdb to do this.
