  • C++: what regex library should I use?

    - by Stéphane
    I'm working on a commercial (not open source) C++ project that runs on a linux-based system. I need to do some regex within the C++ code. (I know: I now have 2 problems.) QUESTION: What libraries do people who regularly do regex from C/C++ recommend I look into? A quick search has brought the following to my attention: 1) Boost.Regex (I need to go read the Boost Software License, but this question is not about software licenses) 2) C (not C++) POSIX regex (#include <regex.h>, regcomp, regexec, etc.) 3) http://freshmeat.net/projects/cpp_regex/ (I know nothing about this one; seems to be GPL, therefore not usable on this project) Thanks.

  • Creating an installer with WPF forms, packaged files and custom setup actions in C#

    - by RodH257
    I'm trying to create a way of deploying a set of tools (which are add-ins to 3rd party software) to my users. I would like to do the following: User Enters Serial Dlls in their directory structure is extracted to program files a file is copied to a location in ProgramData (this registers my add-ins to the 3rd party application) Online activation for software is performed Can anyone point me into the right direction for this? I had a look at deployment projects in Visual Studio but I'm not sure if they are what I'm after. Main problem is they are ugly, I would like to have a nice WPF installer, and have a more custom experience. But I guess that can be traded off if its going to make things easier. I was thinking, I could just make my own C# project that extracts the files, but I have no idea how to package them up and extract them all as part of one download (like the MSI files that the deployment projects create). Can anyone point me in the right direction?

  • What next in the career map for a Lead QA Engineer

    - by chandran
    I am a Lead QA Engineer in a Software company and at a stage in my career wherein i need to plan my next move. Option 1: The very obvious move would be to stay as a QA Lead and eventually become a QA Manager. But i don't see very good prospects/future after that. Or am i wrong? Option 2: I love programming/coding, though i haven't spent a whole lot of time on that. So a direct move to becoming a Software Developer is not possible. Will moving to Test Automation eventually lead me to development. Even so, am i looking at step-down in pay and career-level. Option 3: Moving to Product Management. Is this even possible and if so what would be the best approach. Appreciate all your responses in advance. Thanks.

  • Slow draw on some apps and dynamic clocks not working properly with ATI/AMD proprietary drivers

    - by Rakeka
    I've recently purchased a new computer (around July 2010) and I've been having some problems with proprietary video drivers on Linux. The hardware is: Video: ATI/AMD Radeon HD 5870 (XFX HD-587X-ZNFC); Motherboard: Asus P7P55D-E Deluxe; Processor: Intel i5 750; Memory: Kingston Hyperx KHX1600C8D3K2/4GX (2x - 8GB Total); Power Supply: XFX P1-750B-CAG9; There are no overclocks, not even the memories (they are at 1333mhz due processor memory controller limitation). The operational system is a homebrew Linux distribution with the following software: Architecture: x86_64 (multilib) Kernel: 2.6.35.10 Xorg: 7.5 Window Manager: wmii-3.9.2 Video Driver: ATI/AMD Catalyst 10.12 There are no desktop effects programs like compiz fusion or beryl. The problems: With ATI/AMD proprietary driver, some applications are with slow draw/redraw, and, the same applications make the driver to increase the card clocks to maximum (0% gpu activity, only the clocks are increased). I dunno exactly how to describe the slow draw but I'll list some applications and symptoms. xterm Flickers a lot when drawing continuous output; When I'm in a workspace with fullscreen xterm, The gpu load stays at 12% in idle, and, with smaller xterm, smaller GPU load. "aticonfig --odgc" output: Default Adapter - ATI Radeon HD 5800 Series Core (MHz) Memory (MHz) Current Clocks : 157 300 Current Peak : 850 1200 Configurable Peak Range : [600-900] [900-1300] GPU load : 12% "aticonfig --pplib-cmd 'get activity'" output: Current Activity is Core Clock: 157MHZ Memory Clock: 300MHZ VDDC: 950 Activity: 12 percent Performance Level: 0 Bus Speed: 5000 Bus Lanes: 16 Maximum Bus Lanes: 16 More examples: mplayer time info flickers on terminal; "find /" flickers a lot (It takes some time to stop with control-c. But, If I change the workspace or put some window upon it, just after the control-c, it stops instantly); "cat somefile" if the file is big (Xorg.0.log for example) it takes some time to display; vim and less (ex: find / | less) don't have much problems, just a little flicker when scrolling; mplayer (no gui) Slow reproduction and seek with -vo x11; Tearing with -vo xv; Time info flickers on terminal (xterm consequence); gvim A little slow draw when scrolling with page up/page down; Firefox Slow draw/redraw on some pages like www.boadica.com.br and sometimes on www.youtube.com with flash enable (never noticed on many pages); Corruptions when informative yellow boxes are showing and scroll the page (an gray box appears at the same place of the informative box); "Wallpaper" After minimizing a fullscreen window or changing to an empty workspace it takes some time to redraw wallpaper. "Video Card" The core and memory clocks are increased with the events described above and on other situations like change workspace (even without wallpaper), minimize, maximize or move a window; Idle clocks: Core: 157mhz, Memory: 300mhz Full clocks: Core: 850mhz, Memory: 1200mhz xpdf Painful slow scrolling; display (from ImageMagick) Slow menus and sometimes slow image redraw; Programs that I use and are apparently without problems: gimp; pidgin; mplayer (-vo gl, gl2); blender; unigine heaven (better fps than on Windows); doom3; tibia; penumbra overture; amnesia the dark descent (wine); diablo 2 (wine); No problems on Windows (Windows 7 Ultimate 64bit). And special note to this: Full desktop effects from Debian and Ubuntu gnome appearance cpanel don't cause ANY problems, even the core and memory clocks don't increase when change workspace, minimize, maximize or move a window. What I've tested: Unsuccessful tests: Tested all drivers versions since 10.6 (released approximately when I've installed the first slackware in this PC); Tested other video card - ATI/AMD Radeon HD 5570 (XFX HD-557X-ZHF2); Tested some options on xorg.conf and that I've found googling (some of these options are commented on my xorg.conf. I'll send the links at the end of post); Tested some patches like 107_fedora_dont_fill_bg_none.patch and xserver-xorg-backclear.patch from Arch Linux Catalyst page (https://wiki.archlinux.org/index.php/ATI_Catalyst); Tested other distros and software versions: Tested XORG-7.6 on my own distribution; Tested Debian Squeeze (testing - from 2010-12-20); Tested Ubuntu Marverick (10.10); Tested Slackware 13.1; Distros info: Architecture: i386 Debian and Ubuntu with all default software (kernel, gnome, xorg, drivers); Slackware with Catalyst from AMD page and default window managers like: fvwm, xfce, and my own build of wmii; Successful tests: Tested other video card (only on my homebrew distro) - NVIDIA Geforce 7300GS with driver 260.19.29; That didn't shown the slow draw problems, but that card is a bit obsolete, so, dunno if that lacks features like the dynamic clocks. I don't dispose of other video cards like nvidia g/gt/gts/gtx 200~400~500 or Radeon HD 3000/4000/6000 to make more tests. Tested other hardware: Video: ATI/AMD Radeon HD 5570 (XFX HD-557X-ZHF2); Motherboard: Intel DG31PR; Processor: Core 2 Duo E6750; Software for that hardware: Fresh install of same distros (except for the mine) with same program versions; That video card (HD 5570) were full time at the maximum clocks (something like 500/750, don't remember) in all the operational systems (Windows XP and Windows 7 too), but it didn't shown the same problems that I have here. I've googled a lot about common problems with ATI/AMD proprietary drivers for Linux and didn't find similar problems, except by the Firefox corruptions, that the solutions were to disable ATI Direct2DAccel and use XAA. With XAA the problems persists and the other applications like pidgin and rest of Firefox showed the same problems of slow draw/redraw. Open source Drivers: With open source drivers (xf86-video-ati-6.13.2) I hadn't the same slow draw problems, but, had other problems, that, for now, make it no viable solution. I'll not discuss it here because this is another line of problems and will confuse everything. If it happens to be the only solution, I'll make another thread to discuss it. Logs and Configs: kernel .config dmesg xorg package list xorg.conf Xorg.0.log

  • Why are the colors worse on Ubuntu 12.04 than on Windows 7 on my Sony Vaio E-Series?

    - by Simon Hoare
    The colours look "lacking" and ever slightly blueish and rather washed-out and lacking in dimension. Graphics are ok - this page for example looks fine - but if I view something like a news site with high quality photos, the experience is not optimal and is noticeably inferior to Windows 7. Oddly, when I install Ubuntu as a VM on VirtualBox in Windows, the colours look as I expect them to. It's only on my dual-boot version of Ubuntu that they look wrong (not Wubi, although a previous Wubi-based installation had the same problem). Now, I have the proprietary ATI driver and I can use amdcccle to get the colours closer to what they should be, but I can't seem to do anything about colour depth. The depth settings in Xorg are all 24. I tried changing all three mentions of 24 to 32 but was forced into safety mode. Fortunately, I remembered where I'd been tinkering and got the file set back to 24.

  • programmatically controlling power sockets in the UK

    - by cartoonfox
    It's very simple. I want to plug a lamp into the UK mains supply. I want to be able to power it on and off from software - say from serial port commands, or by running a command-line or something I can get to from ruby or Java. I see lots written about how to do this with X10 with American power systems - but has anybody actually tried doing this in the UK? If you got this working: 1) Exactly what hardware did you use? 2) How do you control it from software? Thanks!

  • Is php|architect any good?

    - by Andrew Heath
    Kind of a hard topic to search for, as architect turns up a lot about software architects instead. After 8 months of PHP self-study, I finally stumbled across the php|architect site. The length of time it took me to find it makes me suspicious of its quality. 3 related questions: do professional PHP coders read/care about php|architect? is it a good source for PHP beginners? assuming yes to either of the above, how far back in the archives to articles remain relevant? (ex: does stuff written about PHP4 still matter?)

  • Ipad, closed environment and threat to privacy

    - by Akshay Bhat
    I had an unusual question about ipad, Since ipad environment is closed and does not allows installation of diagnostic and security related programs. How can then we be sure that any of the software installed on ipad is not infringing upon our privacy by doing stuff such as homing back information, etc. We cant install a packet tracer or any other software to check for attacks on privacy. Also given Apples poor track record (the safari browser was broken in one day), I don't think trusting apple solely would be a good idea. This might not seem to be a big issue but for business users it would be a significant concern.

  • How do I figure out which SOC or SDK board to use?

    - by Ram Bhat
    Hey guys Basically I'm working on a model of an automated vacuum cleaner. I currently have made software simulation of the same. How do I figure out which SOC or SDK board to use for the hardware implementation? My code is mostly written in C. Will this be compatible with the sdk provided by board manufacturers? How do i know what clock speed,memory etc the hardware will need? I'm a software guy and have only basic knowledge about practical hardware implementations. Have some experience in programming the 8086 to carry out basic tasks.

  • Can not print after upgrading from 12.x to 14.04

    - by user318889
    After upgrading from V12.04 to V14.04 I am not able to print. I am using an HP LaserJet 400 M451dn. The printer troubleshooter told me that there is no solution to the problem.

  • What a week! Oracle OpenWorld & Maria Bartiromo (CNBC)

    - by Carlos Chang
    It's been a week since the end of Oracle OpenWorld and JavaOne and both events were a huge success! We had many announcements including Oracle ADF Mobile, Oracle ADF Essentials, Oracle Developer Cloud Service and tons more.  Above is a picture I snapped of Maria Bartiromo from CNBC, who was there to interview Larry Ellison and Mark Hurd.  The stage was right in the midst of the booths that showcased new products, at Moscone North.  She's such a pro. With all the noise and people milling around gawking and taking pictures (myself included) she was solid & composed.   Her level of focus and the production quality of the show is impressive. She later stopped by for a demo of OEPE's  new support for Oracle ADF as well as Oracle Developer Cloud Service. She seemed impressed too. ;-)

  • Best PHP framework for an experienced PHP developer?

    - by andybaird
    Okay, before I start this, I am well aware of how subjective this question is. For my case, I'd like to define the 'best' for me as: Rapid development "Pretty" URLs Data validation Good knowledge base available Not impossible to integrate other PHP software with This is a pretty generic definition, but all I'm looking for here is opinions. Edited: Here's a better way to ask this question: You have two weeks to create a full scale booking and scheduling system that accepts Google Checkout payments (via the API) and integrates with an open source message board software. Which framework do you choose and why?

  • Streaming audio - where to start?

    - by Adam Davis
    I need to develop an embedded audio streaming server. Requirements: Voice quality or better Intended for low power wifi transmission Broad support in existing software and devices (ie, windows media player, quicktime, vlc, iPhone, Android, etc). Royalty/patent free, or cheap to license Preferences: Low overhead TCP/IP based streaming protocol Voice grade codec (easy to implement in software, no DSP, 32bit CPU if needed) Would be nice if it supported HTML5 browsers, but is there any codec (such as raw) that is supported by the latest browsers that is lower overhead than MP3? Therefore: What are the relevant streaming protocols I should be looking at? What are the relevant codecs I should be looking at? What transport streams should I be looking at? What am I missing, or where else should I be looking for this type of need?

This post attempts to highlight some of the best practices along with dos & don’ts that our practice has accumulated over the years in the identity & access management space in general, and also in the context of R2, in particular. Best Practices The following section illustrates the leading practices in “How” to plan, implement and sustain a successful OIM deployment, based on our collective experience. Planning is critical, but often overlooked A common approach to planning an IAM program that we identify with our clients is the three step process involving a current state assessment, a future state roadmap and an executable strategy to get there. It is extremely beneficial for clients to assess their current IAM state, perform gap analysis, document the recommended controls to address the gaps, align future state roadmap to business initiatives and get buy in from all stakeholders involved to improve the chances of success. When designing an enterprise-wide solution, the scalability of the technology must accommodate the future growth of the enterprise and the projected identity transactions over several years. Aligning the implementation schedule of OIM to related information technology projects increases the chances of success. As a baseline, it is recommended to match hardware specifications to the sizing guide for R2 published by Oracle. Adherence to this will help ensure that the hardware used to support OIM will not become a bottleneck as the adoption of new services increases. If your Organization has numerous connected applications that rely on reconciliation to synchronize the access data into OIM, consider hosting dedicated instances to handle reconciliation. Finally, ensure the use of clustered environment for development and have at least three total environments to help facilitate a controlled migration to production. If your Organization is planning to implement role based access control, we recommend performing a role mining exercise and consolidate your enterprise roles to keep them manageable. In addition, many Organizations have multiple approval flows to control access to critical roles, applications and entitlements. If your Organization falls into this category, we highly recommend that you limit the number of approval workflows to a small set. Most Organizations have operations managed across data centers with backend database synchronization, if your Organization falls into this category, ensure that the overall latency between the datacenters when replicating the databases is less than ten milliseconds to ensure that there are no front office performance impacts. Ingredients for a successful implementation During the development phase of your project, there are a number of guidelines that can be followed to help increase the chances for success. Most implementations cannot be completed without the use of customizations. If your implementation requires this, it’s a good practice to perform code reviews to help ensure quality and reduce code bottlenecks related to performance. We have observed at our clients that the development process works best when team members adhere to coding leading practices. Plan for time to correct coding defects and ensure developers are empowered to report their own bugs for maximum transparency. Many organizations struggle with defining a consistent approach to managing logs. This is particularly important due to the amount of information that can be logged by OIM. We recommend Oracle Diagnostics Logging (ODL) as an alternative to be used for logging. ODL allows log files to be formatted in XML for easy parsing and does not require a server restart when the log levels are changed during troubleshooting. Testing is a vital part of any large project, and an OIM R2 implementation is no exception. We suggest that at least one lower environment should use production-like data and connectors. Configurations should match as closely as possible. For example, use secure channels between OIM and target platforms in pre-production environments to test the configurations, the migration processes of certificates, and the additional overhead that encryption could impose. Finally, we ask our clients to perform database backups regularly and before any major change event, such as a patch or migration between environments. In the lowest environments, we recommend to have at least a weekly backup in order to prevent significant loss of time and effort. Similarly, if your organization is using virtual machines for one or more of the environments, it is recommended to take frequent snapshots so that rollbacks can occur in the event of improper configuration. Operate & sustain the solution to derive maximum benefits When migrating OIM R2 to production, it is important to perform certain activities that will help achieve a smoother transition. At our clients, we have seen that splitting the OIM tables into their own tablespaces by categories (physical tables, indexes, etc.) can help manage database growth effectively. If we notice that a client hasn’t enabled the Oracle-recommended indexing in the applicable database, we strongly suggest doing so to improve performance. Additionally, we work with our clients to make sure that the audit level is set to fit the organization’s auditing needs and sometimes even allocate UPA tables and indexes into their own table-space for better maintenance. Finally, many of our clients have set up schedules for reconciliation tables to be archived at regular intervals in order to keep the size of the database(s) reasonable and result in optimal database performance. For our clients that anticipate availability issues with target applications, we strongly encourage the use of the offline provisioning capabilities of OIM R2. This reduces the provisioning process for a given target application dependency on target availability and help avoid broken workflows. To account for this and other abnormalities, we also advocate that OIM’s monitoring controls be configured to alert administrators on any abnormal situations. Within OIM R2, we have begun advising our clients to utilize the ‘profile’ feature to encapsulate multiple commonly requested accounts, roles, and/or entitlements into a single item. By setting up a number of profiles that can be searched for and used, users will spend less time performing the same exact steps for common tasks. We advise our clients to follow the Oracle recommended guides for database and application server tuning which provides a good baseline configuration. It offers guidance on database connection pools, connection timeouts, user interface threads and proper handling of adapters/plug-ins. All of these can be important configurations that will allow faster provisioning and web page response times. Many of our clients have begun to recognize the value of data mining and a remediation process during the initial phases of an implementation (to help ensure high quality data gets loaded) and beyond (to support ongoing maintenance and business-as-usual processes). A successful program always begins with identifying the data elements and assigning a classification level based on criticality, risk, and availability. It should finish by following through with a remediation process. Dos & Don’ts Here are the most common dos and don'ts that we socialize with our clients, derived from our experience implementing the solution. Dos Don’ts Scope the project into phases with realistic goals. Look for quick wins to show success and value to the stake holders. Avoid “boiling the ocean” and trying to integrate all enterprise applications in the first phase. Establish an enterprise ID (universal unique ID across the enterprise) earlier in the program. Avoid major UI customizations that require code changes. Have a plan in place to patch during the project, which helps alleviate any major issues or roadblocks (product and database). Avoid publishing all the target entitlements if you don't anticipate their usage during access request. Assess your current state and prepare a roadmap to address your operations, tactical and strategic goals, align it with your business priorities. Avoid integrating non-production environments with your production target systems. Defer complex integrations to the later phases and take advantage of lessons learned from previous phases Avoid creating multiple accounts for the same user on the same system, if there is an opportunity to do so. Have an identity and access data quality initiative built into your plan to identify and remediate data related issues early on. Avoid creating complex approval workflows that would negative impact productivity and SLAs. Identify the owner of the identity systems with fair IdM knowledge and empower them with authority to make product related decisions. This will help ensure overcome any design hurdles. Avoid creating complex designs that are not sustainable long term and would need major overhaul during upgrades. Shadow your internal or external consulting resources during the implementation to build the necessary product skills needed to operate and sustain the solution. Avoid treating IAM as a point solution and have appropriate level of communication and training plan for the IT and business users alike. Conclusion In our experience, Identity programs will struggle with scope, proper resourcing, and more. We suggest that companies consider the suggestions discussed in this post and leverage them to help enable their identity and access program.

  • What are the advantages of a $ SKU of VS2012 over Express?

    - by Clay Shannon
    I will be using Visual Studio only for creating C#/XAML Windows Store apps. Is there any reason for me to purchase a "Professional" SKU of VS 2012 rather than just using the Express (free) "Metro apps with C#/XAML" version? The only thing I can think of is that I won't be able to use Resharper in the Express version (which I've already purchased a license for, but I use it at work, so that won't be a waste of money if I can't use it at home) - plus, I believe that even the Express SKU of VS 2012 will have similar code quality utility built in.
