  • How can I check myself when I'm the only one working on a project?

    - by Ricardo Altamirano
    I'm in between jobs in my field (unrelated to software development), and I recently picked up a temporary side contract writing a few applications for a firm. I'm the only person working on these specific applications. Are there ways I should be checking myself to make sure my applications are sound? I test my code, try to think of edge cases, generate sample data, use source control, etc. but since I'm the only person working on these applications, I'm worried I'll miss bugs that would easily be found in a team environment. Once I finish the application, either when I'm happy with it or when my deadline expires, the firm plans to use it in production. Any advice? Not to use a cliche, but as of now, I simply work "to the best of my ability" and hope that it's enough. Incidentally, I'm under both strict NDA's and laws about classified material, so I don't discuss the applications with friends who have actually worked in software development. (In case it's not obvious, I am not a software developer by trade, and even my experience with other aspects of information technology/computer science are limited and restrained to dabbling for the most part).

  • New Development Snapshot

    I got a little side tracked by the investigation of the Google Collections test suite performance issue, reported by Albert Strasheim in the comments to the previous snapshot. This caused me to do some work on exception handling (unfortunately without any performance benefit to the Google Collections test suite) which, in turn, triggered something I've been wanting to do for while, namely to introduce a stub version of IKVM.OpenJDK.Core.dll which can...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Counting product releases if you work on the backend/online services?

    - by stackoverflowuser2010
    I am trying to update my resume, and I would like to count the number of "product releases" that I was directly involved in with a company. It would seem to serve as a performance metric. The problem is that I was working on the backend of a very large distributed system, like along the lines of Hadoop or other huge database. We had regular 6-month major releases and other minor releases. My manager kept saying that "shipped" these releases, but "shipping" a product to me sounds like releasing single pieces of software, like Microsoft would ship Office 11 or something. Any ideas on "product releases" for backend service engineers, or any other type of performance metric?

  • i18n and L10n (1)

    - by Aaron Li
    Internationalization (i18n) is a way of designing and developing a software product to function in multiple locales. This process involves identifying the locales that must be supported, designing features which support those locales, and writing code that functions equally well in any of the supported locales. Localization (L10n) is a process of modifying or adapting a software product to fit the requirements of a particular locale. This process includes (but may not be limited to) translating the user interface, documentation and packaging, changing dialog box geometries, customizing features (if necessary), and testing the translated product to ensure that it still works (at least as well as the original). i18n is a pre-requisite for L10n. Resource is 1. any part of a program which can appear to the user or be changed or configured by the user. 2. any piece of the program's data, as opposed to its code. Core product is the language independent portion of a software product (as distinct from any particular localized version of that product - including the English language version). Sometimes, however, this term is used to refer to the English product as opposed to other localizations.   Useful links http://www.mozilla.org/docs/refList/i18n/ http://www.w3.org/International/ http://hub.opensolaris.org/bin/view/Community+Group+int_localization/

  • Setting Up and Running Summary Advisor on an Exalytics Machine (Oracle-by-Example)

    - by Saresh
    If you are running Oracle BI on an Exalytics machine, you can use Summary Advisor to identify the aggregates that will increase query performance. Summary Advisor intelligently recommends an optimal list of aggregate tables based on query patterns that will achieve maximum query performance gain while meeting specific resource constraints. Summary Advisor then generates an aggregate creation script that can be run to create the recommended aggregate tables. Aggregate tables reduce query times by storing precomputed results for queries that include rolled-up data. This tutorial covers steps to set up, configure, and run Summary Advisor on an Exalytics machine using TimesTen database as a target for storing aggregates. You can find the Oracle By Example (OBE) in the Oracle Learning Library (OLL). The content in OLL is available to all customers, partners, and employees.

  • Create an RSS feed for any webpage, monitor changes and send results by email?

    - by David
    Do you know a Windows 7 software (not an online service) than can create an RSS feed for any webpage ? Here is what I am looking for : I manually select what is a title, what is a link and if needed what is the content that I would like to keep (article content + their related images if they exist). The software create a RSS feed from that. Then it monitors the feed every x hours (or x days at a specified time). If updates are found then send the results to my email address. (It is a little like a combination of the Firefox addon: Autopager (WYSIWYG selection which use xpath) and WebSite-Watcher (RSS software monitoring).

  • Make exact copy of USB stick [closed]

    - by Andrius Palivonas
    There's this school software on a USB drive. It only runs, when the stick they gave is plugged in. Cloning the drive with dd command didn't work. I'm guessing it checks the hardware ID of the flash drive. Is there any way to change drives information? I guess not, but is it possible to create a virtual flash drive with exactly same hardware id and all other read-only information that the software is most probably checking. EDIT: The paper math books we have dont' have answers. So when I'm doing homework I have no idea if did it right. The electronic version does have the answers. The publisher didn't put them into paper version because of simple reason - money. They would have to republish the book if some answers are found to be wrong. So I feel no shame trying to pirate that software, because publishers are ruining our math education.

  • Create and copy a Windows Mobile 5.0 operating system image

    - by user20119
    We have several dozen Windows Mobile 5.0 devices (Symbol MC7095 handhelds equipped with embedded Verizon WLAN, if that matters) that all need the same software and configuration. We connect all of these devices via a USB cradle to add software to them via Microsoft ActiveSync, and then do several configuration changes directly on the handhelds themselves, in the OS. That process takes 30 minutes or more, per device. Is there any way to set up one device and take a 'disk image' of the entire OS/software, such that things could then be copied (quickly/easily) to the other devices? Is such a thing possible, with Windows Mobile devices?

  • Looking for 'WinHlp32.exe compatible' replacement for free redistribution under vista and windows 7

    - by richardboon
    Our software installs a package of legacy software for the client, some of it has old hlp file from 3rd party vendor requiring winhlp32.exe (note: we have no legal right to modify the hlp). Those client may only have cd/dvd and might not have internet access, etc. So I need a free 'WinHlp32.exe compatible' replacement for our redistribution under vista and windows 7. Background of problem: -Microsoft stopped including the 32-bit Help file viewer in Windows releases beginning with Windows Vista and Windows Server 2008. -Starting with the release of Windows Vista and Windows Server 2008, third-party software developers are no longer authorized to redistribute WinHlp32.exe with their programs. http://support.microsoft.com/kb/917607

  • What are the current options to encrypted a partition on mac os x ?

    - by symbion
    I recently got my laptop stolen with some sensitive informations on it (personal source code, bank details in a secure file, passwords, etc) and I learnt the lesson: encrypt your sensitive data. Now, I am wondering what are the options to encrypt a partition (not an encrypt disk image) ? Aim: The aim is to prevent anyone (except me) to access those data. Requirement 0: The software must be able to encrypt non system partition. Requirement 1: Plausible deniability is required but preventing cold boot attack is however not an absolute requirement (I am not famous enough or have sensitive enough info to have this kind of requirement). Requirement 2 : Software taking advantage of AES hardware encryption are very welcome as I intent to get a Macbook Pro with i7 CPU (with AES-NI enabled instructions). I will have avirtual machine running in the encrypted partition. Requirement 3 : Free or reasonably cheap. Requirement 4 : Software must run on Mac OS X Snow Leopard or Lion. So far, TrueCrypt is the only option I have found. Regards,

  • Windows 7 - Static DHCP server address with dynamic IP Address

    - by mkstreet
    Is this possible? On my LAN, I would like to setup the network properties such that the DHCP server's address is static. However, I want that server to hand out the IP Addresses and DNS addresses dynamically. The reason is that some devices on the LAN will try to behave like a DHCP server. For example, we use software to push images to computers on the LAN (our computer software configurations are centrally managed). When that imaging distribution software happens to be running, the machines being imaged will get confused as to which device is the DHCP -- the real one or the machine that is sending them the image. So, to remove the confusion, I would like to setup my Windows 7 images such that the DHCP server address is statically assigned. And then that server would assign the IP Addresses and the DNS addresses dynamically.

  • Kill program after it outputs a given line, from a shell script

    - by Paul
    Background: I am writing a test script for a piece of computational biology software. The software I am testing can take days or even weeks to run, so it has a recover functionality built in, in the case of system crashes or power failures. I am trying to figure out how to test the recovery system. Specifically, I can't figure out a way to "crash" the program in a controlled manner. I was thinking of somehow timing a SIGKILL instruction to run after some amount of time. This is probably not ideal, as the test case isn't guaranteed to run the same speed every time (it runs in a shared environment), so comparing the logs to desired output would be difficult. This software DOES print a line for each section of analysis it completes. Question: I was wondering if there was a good/elegant way (in a shell script) to capture output from a program and then kill the program when a given line/# of lines is output by the program?

  • Ubuntu Linux -- create custom burnable/bootable DVD image?

    - by ashgromnies
    I recently developed some kiosk software that runs on Ubuntu Linux, and my client needs me to set up ten more computers with the complete software package(and that number will only grow in the future). So I'm looking for a way to make this less of a pain in the neck and prevent me from shooting myself in the foot -- I had to disable some things on the installations of the operating systems like screensavers, automatic updates, etc. that would pop up and disrupt the kiosk operation. I don't feel comfortable doing that by hand across 10 computers, it seems stupid. Does anybody have recommendations for software that would let me burn an installable DVD with a complete image of the hard drive from one of the devices? I've looked at Clonezilla, G4L, and PartImage and I'm still not quite sure if any of them offer what I need. I know PartImage for sure won't work, because it doesn't support Ext4.

  • PS2 Eyetoy Recording Quality

    - by Fire
    I have Ubuntu 12.04 LTS and a PS2 eyetoy "Namtai". Don't worry - this is not the sterotypical " how do I get my eyetoy working" question. My eyetoy works fine on Cheese, gucview and various other media software like VLC. However, It seems like I am capped by 25fps. If I recall, the eyetoy is much better than this (~60fps) but cannot find any way to fix this. The best program that I have have found is VLC because its advanced options allow you to change many settings but the framerate setting appears to have no effect. What software or settings can I use to take full advantage of my eyetoy? To give you the full information I wish to attach multiple eyetoys to the system and record from all of them. (Security software like motion and zoneminder, I couldn't get installed correctly on my system- so I haven't tried those yet). edit - I tried the same camera on a Windows system and the frame rate is much better in VLC compared to the Ubuntu system. Mind you with default settings in Windows VLC, the resolution isn't great. However, in Skype for example the resolution is amazing and the framerate is good. It seems there must be some settings I am missing somewhere because it doesn't appear to be a hardware problem...

  • Solaris 11 installed, no updates?

    - by Paul De Niro
    I was messing around with solaris and decided to give Solaris 11 a try so I downloaded it from the Oracle website. After installing the OS, I went into the package manager and did an update. It told me that there were to available updates! I find this hard to believe considering that it's running a vulnerable version of firefox and java, its own in-house software product! Many of the other software products that came with the default install are also out of date and vulnerable. Is this normal for an Oracle install, or did I do something wrong with the upgrade process? I typed "pkg update" at the prompt, and I noticed that it did call out to pkg.oracle.com looking for updates. I find it bizarre that there are no updates available for an OS that was released a couple months ago with vulnerable software...

  • Is it possible to keep only one Database for both web and desktop applications?

    - by B4NZ41
    I'm experiencing a trouble with my business model, let me explain better. I'm developing a software for 1 year and few months, it's for the food industry, more exactly a software to: Delivery, Take Way, Table Reservation, POS, Accounts Payable and Receivable, Prints(receipt), Kitchen Monitors Orders, Customers Orders Control and Fiscal Area. Well, I had separated the software mainly in two areas, one is web area and the other is desktop area (Used by Admins only) and local installed. 1 - Web Area (Basically do the follow:) Show Catalog with the products Customers Make Orders Customers Pay for the Orders etc ... as mentioned above 2 - Desktop Area Manage Orders Manage Customers Manage Suppliers Manage Accounts Payable and Receivable etc ... as mentioned above The web area is hosted in an online web server (scripts and database are online). The Desktop area is hosted locally in a Linux machine with a local database and local scripts files. My question is: Is it possible to keep only one Database for both applications? If YES, please what is the best approach? Follow my technical specification environment Database: Actually I have two databases working and I would love to keep only one. Operating System: Linux (Kernel 2.6.X and above) or Windows (XP and above) For the Web Area Apache, PHP, Python, Java Script, Shell Script and MySQL. For the Desktop Area: PHP-GTK2, Apache, PHP, MySQL and Shell Script.

  • how to switch played music when someone enters

    - by ymajoros
    My wife has a small shop, and she plays free licensed music. She can't legally play her own music when people outside of the family circle are present in the shop. How can I automatically switch music when someone enters? I was thinking of some bluetooth door detector and some custom software, but can't seem to find either. I'm a software architect/dev and can write it if necessary, but I'd prefer to use some existing solution. Any ideas on good hardware and software for this?

  • Can I eventually consider myself a professional developer if I don't have a CS degree? [on hold]

    - by heltonbiker
    Question first, context later: If I am a dedicated, self-taught programmer, always seeking top-quality books AND READING THEM, while successfully applying all that new knowledge into my current work, could I call myself (and offer my work as) a PROFESSIONAL developer? How limiting (or how common) that is nowadays? I am afraid that, no matter how hard I study and practice, it could be too difficult to compete with "actual", college graduated developers, and potential employers might have doubts investing in an "undergraduated" person. Now, context: My former profession is from healthcare sector, then I studied mechanical engineering (quit in the middle), then I studied product design (master degree), and I ended up working (very happily) at an engineering company that manufactures medical devices. For more than two years now my main activity in this company is software development. The devices contain software, and we gave up hiring software development (domain knowledge needed, too much communication cost). My current company sees a lot of value in what I do, but I cannot afford the risk of depending on this single company for the rest of my life, you get it. But a lot of job offers require some minimal formal education, usually a CS degree. Fact is that I am sure this is my target profession, I don't plan to go to another area, it is a pleasure to dive into books that normal people would consider unreadable, but I'm 36 years old and can't see going back to college as a viable alternative.
