• apt-get install is not able to access /etc

  - by HorusKol

  I put together an ubuntu 12.04 server a couple of weeks ago and everything seemed fine until this morning. Suddenly, I'm having trouble installing new packages - at first I thought there was something wrong with tinyproxy and so I tried installing squid instead. However, I get similar results: Starting tinyproxy: tinyproxy: Could not open config file "/etc/tinyproxy.conf".\ ... /var/lib/dpkg/info/squid3.postinst: 1: /var/lib/dpkg/info/squid3.postinst: cannot open /etc/squid3/squid.conf: No such file It seems that apt-get is not creating the configuration files needed for these programs. I haven't modified any configuration or user groups since the last successful update/install of packages. /etc is present, and is populated with a nice healthy tree of configuration files. It is owned and grouped to root, and has the properties drwxr-xr-x - all the files and folders inside seem to be fine to, as far as I can tell. I've even been able to edit/save a couple as sudo.

• Mysql-server-5.5 broken after update

• Advice on designing a robust program to handle a large library of meta-information & programs

  - by Sam Bryant

  So this might be overly vague, but here it is anyway I'm not really looking for a specific answer, but rather general design principles or direction towards resources that deal with problems like this. It's one of my first large-scale applications, and I would like to do it right. Brief Explanation My basic problem is that I have to write an application that handles a large library of meta-data, can easily modify the meta-data on-the-fly, is robust with respect to crashing, and is very efficient. (Sorta like the design parameters of iTunes, although sometimes iTunes performs more poorly than I would like). If you don't want to read the details, you can skip the rest Long Explanation Specifically I am writing a program that creates a library of image files and meta-data about these files. There is a list of tags that may or may not apply to each image. The program needs to be able to add new images, new tags, assign tags to images, and detect duplicate images, all while operating. The program contains an image Viewer which has tagging operations. The idea is that if a given image A is viewed while the library has tags T1, T2, and T3, then that image will have boolean flags for each of those tags (depending on whether the user tagged that image while it was open in the Viewer). However, prior to being viewed in the Viewer, image A would have no value for tags T1, T2, and T3. Instead it would have a "dirty" flag indicating that it is unknown whether or not A has these tags or not. The program can introduce new tags at any time (which would automatically set all images to "dirty" with respect to this new tag) This program must be fast. It must be easily able to pull up a list of images with or without a certain tag as well as images which are "dirty" with respect to a tag. It has to be crash-safe, in that if it suddenly crashes, all of the tagging information done in that session is not lost (though perhaps it's okay to loose some of it) Finally, it has to work with a lot of images (10,000) I am a fairly experienced programmer, but I have never tried to write a program with such demanding needs and I have never worked with databases. With respect to the meta-data storage, there seem to be a few design choices: Choice 1: Invidual meta-data vs centralized meta-data Individual Meta-Data: have a separate meta-data file for each image. This way, as soon as you change the meta-data for an image, it can be written to the hard disk, without having to rewrite the information for all of the other images. Centralized Meta-Data: Have a single file to hold the meta-data for every file. This would probably require meta-data writes in intervals as opposed to after every change. The benefit here is that you could keep a centralized list of all images with a given tag, ect, making the task of pulling up all images with a given tag very efficient

• Video stutter when using external drive

  - by psion

  When using boxee to play video files off of an external western digital 1TB drive formatted NTFS, I notice a slight stutter in the video every 5-10 seconds. When using mplayer, it doesn't stutter as often, but it still stutters occasionally. If I play the video off of the local sata drive, it plays fine even in boxee. I use this computer as my HTPC and I just switched from windows to linux on it. In windows, I never had any sort of stutter playing movies from the drive. I am using the latest intel graphics drivers (for the intel GMA 950) root@eee-htpc:/home/htpc# grep wd /etc/mtab /dev/sdb1 /mnt/wd2 fuseblk rw,nosuid,nodev,allow_other,blksize=512 0 0 I notice that despite trying to use ntfs or ntfs-3g, ubuntu uses ntfs-fuse which I've heard is slower. /dev/sdb1: Timing buffered disk reads: 80 MB in 3.07 seconds = 26.08 MB/sec root@eee-htpc:/mnt/wd2# dd if=/dev/zero of=./120mb bs=1024 count=120000 root@eee-htpc:/mnt/wd2# time mv ./120mb /home/htpc real 0m2.095s user 0m0.016s sys 0m0.736s Even though fuse has a reputation for being slow, it should easily be fast enough for playing standard definition video files. So why the video stutter? edit: The issue seems to be overhead cpu usage from either playing off of a usb device or ntfs/fuse. Watching CPU usage with top, local files use 10-40% CPU. Watching the same video on the external formatted ntfs, it spikes to 170% (over 100% because of hyperthreading). To me it seems like it must be overhead from the fuse driver, though I don't know if it has more or less overhead than ntfs-3g. It's a EEEBox B202 that has an atom 270, so not exactly the most powerful out there. edit2: I believe the solution would be to use non-fuse drivers or different fuse drivers. so far I have not been able to. edit3: I've probably edited this more times than I should, but as an update I have upgraded ntfs drivers to ntfs-3g 2010.8.8 external FUSE 28 - Third Generation NTFS Driver using the following PPA - ppa:x3lectric/team-iquik-releases. When first opening a video file in boxee that's on ntfs there's still the same amount of lag. After a few minutes of video, the lag seems to go away and the cpu usage comes down to 10-40%. Every so often though, it begins to stutter again. Also, if I skip ahead/back in the file, it begins to stutter a lot.

• After 10 Years, MySQL Still the Right Choice for ScienceLogic's "Best Network Monitoring System on the Planet"

  - by Rebecca Hansen

  ScienceLogic has a pretty fantastic network monitoring appliance.  So good in fact that InfoWorld gave it their "2013 Best Network Monitoring System on the Planet" award.  Inside their "ultraflexible, ultrascalable, carrier-grade" enterprise appliance, ScienceLogic relies on MySQL and has since their start in 2003.  Check out some of the things they've been able to do with MySQL and their reasons for continuing to use MySQL in these highlights from our new MySQL ScienceLogic case study. Science Logic's larger customers use their appliance to monitor and manage  20,000+ devices, each of which generates a steady stream of data and a workload that is 85% write. On a large system, the MySQL database: Averages 8,000 queries every second or about 1 billion queries a day Can reach 175,000 tables and up to 20 million rows in a single table Is 2 terabytes on average and up to 6 terabytes "We told our customers they could add more and more devices. With MySQL, we haven't had any problems. When our customers have problems, we get calls. Not getting calls is a huge benefit." Matt Luebke, ScienceLogic Chief Software Architect.? ScienceLogic was approached by a number of Big Data / NoSQL vendors, but decided against using a NoSQL-only solution. Said Matt, "There are times when you really need SQL. NoSQL can't show me the top 10 users of CPU, or show me the bottom ten consumer of hard disk. That's why we weren't interested in changing and why we are very interested in MySQL 5.6. It's great that it can do relational and key-value using memcached." The ScienceLogic team is very cautious about putting only very stable technology into their product, and according to Matt, MySQL has been very stable: "We've been using MySQL for 10 years and we have never had any reliability problems. Ever." ScienceLogic now uses SSDs for their write-intensive appliance and that change alone has helped them achieve a 5x performance increase.

• Did I lost my RAID again?

  - by BarsMonster

  Hi! A little history: 2 years ago I was really excited to find out that mdadm is so powerful so it even can reshape arrays so you can start with a smaller array and the grow it as you need. I've bought 3x1Tb drives and made RAID-5. It was fine for a year. Then I bought 2x more, and tried to reshape to RAID-6 out of 5 drives, and due to some mess with superblock versions, lost all content. Had to rebuild it from scratch, but 2Tb of data were gone. Yesterday I bought 2 more drives, and this time I had everything: properly built array, UPS. I've disabled write intent map, added 2 new drives as a spare and run a command to grow array to 7-disk. It started working, but speed was ridiculously slow, ~100kb/sec. AFter processing first 37Mb at such an amasing speed, one of old HDDs fails. I properly shutdown PC and disconnected failed drive. After bootup it appeared it recreated intent map as it was still in mdadm config, so I removed it from config and rebooted again. Now all I see is that all mdadm processes deadlocks, and don't do anything. PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1937 root 20 0 12992 608 444 D 0 0.1 0:00.00 mdadm 2283 root 20 0 12992 852 704 D 0 0.1 0:00.01 mdadm 2287 root 20 0 0 0 0 D 0 0.0 0:00.01 md0_reshape 2288 root 18 -2 12992 820 676 D 0 0.1 0:00.01 mdadm And all I see in mdstat is: $ cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md0 : active raid6 sdb1[1] sdg1[4] sdf1[7] sde1[6] sdd1[0] sdc1[5] 2929683456 blocks super 1.2 level 6, 1024k chunk, algorithm 2 [7/6] [UU_UUUU] [>....................] reshape = 0.0% (37888/976561152) finish=567604147.2min speed=0K/sec I've already tried mdadm 2.6.7, 3.1.4 and 3.2 - nothing helps. Did I lost my data again? Any suggestions how can I make it work? OS is Ubuntu Server 10.04.2... PS. Needless to say that data is unaccessible - I cannot mount /dev/md0 as save the most valuable data. You can see my disappointment - the very specific thing I was excited about failed twice taking 5Tb of my data with it.

• Organizing Git repositories with common nested sub-modules

  - by André Caron

  I'm a big fan of Git sub-modules. I like to be able to track a dependency along with its version, so that you can roll-back to a previous version of your project and have the corresponding version of the dependency to build safely and cleanly. Moreover, it's easier to release our libraries as open source projects as the history for libraries is separate from that of the applications that depend on them (and which are not going to be open sourced). I'm setting up workflow for multiple projects at work, and I was wondering how it would be if we took this approach a bit of an extreme instead of having a single monolithic project. I quickly realized there is a potential can of worms in really using sub-modules. Supposing a pair of applications: studio and player, and dependent libraries core, graph and network, where dependencies are as follows: core is standalone graph depends on core (sub-module at ./libs/core) network depdends on core (sub-module at ./libs/core) studio depends on graph and network (sub-modules at ./libs/graph and ./libs/network) player depends on graph and network (sub-modules at ./libs/graph and ./libs/network) Suppose that we're using CMake and that each of these projects has unit tests and all the works. Each project (including studio and player) must be able to be compiled standalone to perform code metrics, unit testing, etc. The thing is, a recursive git submodule fetch, then you get the following directory structure: studio/ studio/libs/ (sub-module depth: 1) studio/libs/graph/ studio/libs/graph/libs/ (sub-module depth: 2) studio/libs/graph/libs/core/ studio/libs/network/ studio/libs/network/libs/ (sub-module depth: 2) studio/libs/network/libs/core/ Notice that core is cloned twice in the studio project. Aside from this wasting disk space, I have a build system problem because I'm building core twice and I potentially get two different versions of core. Question How do I organize sub-modules so that I get the versioned dependency and standalone build without getting multiple copies of common nested sub-modules? Possible solution If the the library dependency is somewhat of a suggestion (i.e. in a "known to work with version X" or "only version X is officially supported" fashion) and potential dependent applications or libraries are responsible for building with whatever version they like, then I could imagine the following scenario: Have the build system for graph and network tell them where to find core (e.g. via a compiler include path). Define two build targets, "standalone" and "dependency", where "standalone" is based on "dependency" and adds the include path to point to the local core sub-module. Introduce an extra dependency: studio on core. Then, studio builds core, sets the include path to its own copy of the core sub-module, then builds graph and network in "dependency" mode. The resulting folder structure looks like: studio/ studio/libs/ (sub-module depth: 1) studio/libs/core/ studio/libs/graph/ studio/libs/graph/libs/ (empty folder, sub-modules not fetched) studio/libs/network/ studio/libs/network/libs/ (empty folder, sub-modules not fetched) However, this requires some build system magic (I'm pretty confident this can be done with CMake) and a bit of manual work on the part of version updates (updating graph might also require updating core and network to get a compatible version of core in all projects). Any thoughts on this?

• Ubuntu on Pandaboard giving me troubles

  - by Jeroen Jacobs

  I'm trying to install the OMAP4 extras for ubuntu on my pandaboard. For some reason, a few packages can't seem to be agree with eachother. This what I did so far: installed on Ubuntu 11.10 on sd card Powered on Pandaboard and let it finish it's initial install Did an "apt-get update" and "apt-get upgrade", to install updates So far, everything went fine, and I was quite happy with my Pandaboard, but then I made the mistake of typing this: apt-get install ubuntu-imap4-extras At first, everything seemed ok, and it started downloading and installing. But then after a while it just crashed. I tried it again but then it gave me this: Reading package lists... Done Building dependency tree Reading state information... Done ubuntu-omap4-extras is already the newest version. You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: gstreamer0.10-openmax : Depends: gstreamer0.10-plugins-bad but it is not going to be installed gstreamer0.10-plugin-ducati : Depends: gstreamer0.10-plugins-bad but it is not going to be installed ubuntu-omap4-extras-multimedia : Depends: gstreamer0.10-plugins-bad (>= 0.10.22-2ubuntu4+ti1.5) but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution). So I tried to the suggestion: apt-get -f install: Reading package lists...

• "sr0" I/O read boot error in Xubuntu 12.10

  - by Entropicurity

  Just recently upgraded Xubuntu 12.10 after having installed 12.04 originally. Ever since that happened, any time I inserted a disk into my DVD/CD reader/writer I would end up getting a number of error messages from my DVD player/Audio player softer, typically with any of them either crashing or returning a GStreamer backend error. So doing some research I tried to mount it manually, and it typically returned the error messages you'll see below: (using the dmesg | grep "sr0" command) [17545.435584] end_request: I/O error, dev sr0, sector 0 [17545.492968] sr 3:0:0:0: >[sr0] [17545.492981] sr 3:0:0:0: >[sr0] [17545.492992] sr 3:0:0:0: >[sr0] [17545.493003] sr 3:0:0:0: >[sr0] CDB: [17545.493020] end_request: I/O error, dev sr0, sector 0 [17545.493058] EXT3-fs (sr0): error: unable to read superblock [17545.553224] sr 3:0:0:0: >[sr0] [17545.553237] sr 3:0:0:0: >[sr0] [17545.553247] sr 3:0:0:0: >[sr0] [17545.553258] sr 3:0:0:0: >[sr0] CDB: [17545.553275] end_request: I/O error, dev sr0, sector 0 [17545.553312] EXT4-fs (sr0): unable to read superblock [17545.611482] sr 3:0:0:0: >[sr0] [17545.611494] sr 3:0:0:0: >[sr0] [17545.611504] sr 3:0:0:0: >[sr0] [17545.611514] sr 3:0:0:0: >[sr0] CDB: [17545.611531] end_request: I/O error, dev sr0, sector 0 [17545.611568] FAT-fs (sr0): unable to read boot sector When I grepped this, the number of error messages just seemed to spill all over the screen, and typically all revolve around the I/O error. I then went into VLC and tried to run the stuff through there, but for some reason it won't read with the default devices. Instead I have to manually input sr0 into each of the /dev/ references and it will play just fine, until I exit out of the program, at which point I have to re-input everything. I have already installed all the media dependencies, both open source and restricted, through the software center. I just found this strange, as out of the box 12.04 there wasn't any problem what so ever. At this point, it could be that all my audio CD's are not in a format that is familiar with the OS (I've read in some places that EXTF4 has issues with this) but I don't see how that could be a problem when the above error messages even tested to see if it is EXT3 as well? I've tried my best to troubleshoot this up till now using existing topics, but it seems that this is a regular problem with a multitude of varying factors that incorporate into it, including but not limited to read/write problems with the format of the CD and right protection. Is there something integral that I am missing?

• Chargeback and showback...both a 'throw back'

  - by llaszews

  Been getting asked again by customers and partners about chargeback and showback in the cloud so thought I would blog on my response to this question. Charge Back background, information and industry analysis: Cloud computing is all about shared resources. These shared resources are computer servers (including memory and CPU), network devices, hard disk storage, database servers, application servers, cooling, floor space, electricity and more. These resources are shared by departments within a company, or by a number of companies, when resources are hosted in the public or hybrid cloud. Currently, hosting providers that run other companies on their cloud platforms do not have an accurate way to measure the shared computing resources used by a specific user let alone used by a specific customer. Additionally, companies running their own cloud data centers, for private or hybrid clouds, have no way of measure and charging back the departments in the company that are using these shared cloud resources. In both cases, the lack of determine shared resource costs and to charge them back to the company, department or user that is using this resources is limited a clear measure of business benefit and impacting company’s ability to measure the Return on Investment (ROI). An IT chargeback system is an accounting strategy that applies the costs of IT services, hardware or software to the business unit in which they are used. This system contrasts with traditional IT accounting models in which a centralized department bears all of the IT costs in an organization and those costs are treated simply as corporate overhead. Showback involves showing the IT costs to a department or customer but not actually charging them for their IT usage. Showback is a gradual method of introducing chargeback into an enterprise. Most companies implement a show back mechanism before a full chargeback system is put in place. Oracle chargeback product: Oracle Enterprise Manager provides tools for defining detailed Chargeback plans spanning different metrics collected for each type of resources as well as defining Cost Centers for grouping costs across multiple developers. Chargeback plans can use not only usage based costs, but also configuration based costs (e.g. version of the platform) or fixed costs (e.g. flat-rate management fee). Chargeback has rich out of the box reports. Trending reports show how charge and resource consumption varies over time, while Summary reports show the breakdown of charges or usage by different dimensions such as Cost Center or Target Type. These reports help consumers in understanding how their charges relate to their consumption and also assist the IT department with budgeting and planning activities. With BI Publisher, the reports can be made available in a variety of formats such as PDF, HTML, Word, Excel or PowerPoint.

• PowerShell - grabbing values out of the registry and running them

  - by Rob Farley

  So I closed an application that runs when Windows starts up, but it doesn’t have a Start Menu entry, and I was trying to find it. Ok, I could’ve run regedit.exe, navigated through the tree and found the list of things that run when Windows starts up, but I thought I’d use PowerShell instead. PowerShell presents the registry as if it’s a volume on a disk, and you can navigate around it using commands like cd and dir. It wasn’t hard to find the folder I knew I was after – tab completion (starting the word and then hitting the Tab key) was a friend here. But unfortunately dir doesn’t list values, only subkeys (which look like folders). PS C:\Windows\system32> dir HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Run PS C:\Windows\system32> Instead, I needed to use Get-Item to fetch the ‘Run’ key, and use its Property property. This listed the values in there for me, as an array of strings (I could work this out using Get-Member). PS C:\Windows\system32> (Get-Item HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Run).Property QuickSet SynTPEnh Zune Launcher PS C:\Windows\system32> Ok, so the thing I wanted wasn’t in there (an app called PureText, whicih lets me Paste As Text using Windows+V). That’s ok – a simple change to use HKCU instead of HKLM (Current User instead of Local Machine), and I found it. Now to fetch the details of the application itself, using the RegistryKey method GetValue PS C:\Windows\system32> (Get-Item HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Run).GetValue('PureText') "C:\Users\Rob\Utilities\PureText.exe" PS C:\Windows\system32> And finally, surrounding it in a bit of code to execute that command. That needs an ampersand and the Invoke-Expression cmdlet. PS C:\Windows\system32> '& ' + (Get-Item HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Run).GetValue('PureText') | Invoke-Expression A simple bit of exploring PowerShell which will makes for a much easier way of finding and running those apps which start with Windows.

• Move Data into the grid for scalable, predictable response times

  - by JuergenKress

  CloudTran is pleased to introduce the availability of the CloudTran Transaction and Persistence Manager for creating scalable, reliable data services on the Oracle Coherence In-Memory Data Grid (IMDG). Use of IMDG architectures has been key to handling today’s web-scale loads because it eliminates database latency by storing important and frequently access data in memory instead of on disk. The CloudTran product lets developers easily use an IMDG for full ACID-compliant transactions without having to be concerned about the location or spread of data. The system has its own implementation of fast, scalable distributed transactions that does NOT depend on XA protocols but still guarantees all ACID properties. Plus, CloudTran asynchronously replicates data going into the IMDG to back-end datastores and back-up data centers, again ensuring ACID properties. CloudTran can be accessed through Java Persistence API (JPA via TopLink Grid) and now, through a new Low-Level API, or LLAPI. This is ideal for use in SOA applications that need data reliability, high availability, performance, and scalability. It is still in its limited beta release, the LLAPI gives developers the ability to use standard put/remove logic available in Coherence and then wrap logic with simple Spring annotations or XML+AspectJ to start transactions. An important feature of LLAPI is the ability to join transactions. This is a common outcome for SOA applications that need to reduce network traffic by aggregating data into single cache entries and then doing SOA service processing in the node holding the data. This results in the need to orchestrate transaction processing across multiple service calls. CloudTran has the capability to handle these “multi-client” transactions at speed with no loss in ACID properties. Developing software around an IMDG like Oracle Coherence is an important choice for today’s web-scale applications and services. But this introduces new architectural considerations to maintain scalability in light of increased network loads and data movement. Without using CloudTran, developers are faced with an incredibly difficult task to ensure data reliability, availability, performance, and scalability when working with an IMDG. Working with highly distributed data that is entirely volatile while stored in memory presents numerous edge cases where failures can result in data loss. The CloudTran product takes care of all of this, leaving developers with the confidence and peace of mind that all data is processed correctly. For those interested in evaluating the CloudTran product and IMDGs, take a look at this link for more information: http://www.CloudTran.com/downloadAPI.ph , or send your questions to [email protected].

• How do I stop icons appearing on the desktop in a particular area?

  - by Seamus

  When I download something to my desktop, or insert a CD or flash drive, the icon appears on my desktop.

• Synchronizing ODSEE and OUD

  - by Etienne Remillon

  When it comes to synchronizing between ODSEE and OUD, what should be the best options ? Couple  options are available - Use one of OUD internal capability called Replication Gateway - Use our synchronization tool called Directory Integration Platform part of Oracle Directory Services Plus - Manuel export and import Let's check pro and cons on each method. Replication Gateway is the natural, out of the box solution to perform the task. We created this as a feature of OUD because it works at our replication protocol level. The gateway perform the required adaptation between the ODSEE's replication protocol and OUD's one. The benefits of doing this is that it provide strong consistency between the to type of directories. This fully leverage conflict management implemented in the replication protocols to ensure that changes are applied in a coherent and ordered manner. It does not require specific modification on existing ODSEE production instances such as turning on "retro changelog". Changes are propagated at near speed of replication in both directions. Replication Gateway can also synchronize information that are stored internally in the directory server such as "xxxxx" account locking managed at ODSEE server level and not via the nsyyyy attribute. OUD replication gateway does no require any specific tools or installation specific procedure. It is manged like other OUD component with monitoring and configuration via the standard console. OUD Replication Gateway does not perform adaptation between ODSEE and OUD. Using Directory Integration Protocol as external component to OUD, brings flexibility in remapping and transformations between ODSEE and OUD. There is a price to pay in using DIP to perform the synchronization task. You will have to turn on the retro change log to get access to changes on the ODSEE side (this will impact disk and CPU usage and performances which could be a serious challenge for your existing ODSEE environment (if you have not provisioned additional hardware and instances). You will not benefits of conflict resolution management and this might have to be addressed at application level, which is not always possible to implement. Using export and import seams very simple, but this methodology cannot ensure an highly available deployment with up to date entries on booth sides. This solution can be used if full HA with up-to-date data is not needed (during synchronization time). It often used  if data-cleaning need to take place to avoid polluting a new environment with old un-necessary data.

• Library to fake intermittent failures according to tester-defined policy?

  - by crosstalk

  I'm looking for a library that I can use to help mock a program component that works only intermittently - usually, it works fine, but sometimes it fails. For example, suppose I need to read data from a file, and my program has to avoid crashing or hanging when a read fails due to a disk head crash. I'd like to model that by having a mock data reader function that returns mock data 90% of the time, but hangs or returns garbage otherwise. Or, if I'm stress-testing my full program, I could turn on debugging code in my real data reader module to make it return real data 90% of the time and hang otherwise. Now, obviously, in this particular example I could just code up my mock manually to test against a random() routine. However, I was looking for a system that allows implementing any failure policy I want, including: Fail randomly 10% of the time Succeed 10 times, fail 4 times, repeat Fail semi-randomly, such that one failure tends to be followed by a burst of more failures Any policy the tester wants to define Furthermore, I'd like to be able to change the failure policy at runtime, using either code internal to the program under test, or external knobs or switches (though the latter can be implemented with the former). In pig-Java, I'd envision a FailureFaker interface like so: interface FailureFaker { /** Return true if and only if the mocked operation succeeded. Implementors should override this method with versions consistent with their failure policy. */ public boolean attempt(); } And each failure policy would be a class implementing FailureFaker; for example there would be a PatternFailureFaker that would succeed N times, then fail M times, then repeat, and a AlwaysFailFailureFaker that I'd use temporarily when I need to simulate, say, someone removing the external hard drive my data was on. The policy could then be used (and changed) in my mock object code like so: class MyMockComponent { FailureFaker faker; public void doSomething() { if (faker.attempt()) { // ... } else { throw new RuntimeException(); } } void setFailurePolicy (FailureFaker policy) { this.faker = policy; } } Now, this seems like something that would be part of a mocking library, so I wouldn't be surprised if it's been done before. (In fact, I got the idea from Steve Maguire's Writing Solid Code, where he discusses this exact idea on pages 228-231, saying that such facilities were common in Microsoft code of that early-90's era.) However, I'm only familiar with EasyMock and jMockit for Java, and neither AFAIK have this function, or something similar with different syntax. Hence, the question: Do such libraries as I've described above exist? If they do, where have you found them useful? If you haven't found them useful, why not?

• Investing in Servers by Intel

  - by Koushal Deshpande

  Originally posted on: http://geekswithblogs.net/BizTalkAndOtherTechs/archive/2013/10/31/investing-in-servers-by-intel.aspxA nice article reference from Intel, refer here. Referees to cloud as well. Choose correctly what you need. 1 Do determine right server for your company. There is no use getting a server that has redundant services but still add to the costs. 2 Do get servers that can be upgraded. A server with limited memory and storage may not be able to keep up with your business growth. The basic memory and storage options might not be sufficient. Consider at least 8GB of RAM and 1 terabyte of hard disk space. 3 Do check the server has at least one Gigabit Ethernet port. This allows high speed transferring of files and increases productivity for your employees. USB and Firewire ports may not be enough as their transfer speed is too low and will affect the productivity of your company. Infinite Technologies is ready to help perform this upgrade. Contact Infinite Technologies now View our other resellers » 4 Do verify that the server comes with documentation. Documentation allows you to make a claim when your server breaks down and is supported by a warranty. 6 Do check the support options for the server from the manufacturer. Different manufacturer has different support options such as maintenance plans and software upgrades. 5 Do always look into the warranty. Get an enhanced warranty that guarantees response and repair time to avoid disruption. 7 Do get server management tools that can be used on any computer. Server management tools should be cross compatible across different operating systems to take into account future PC replacements. 8 Do check the power usage of the servers. Get the right power supply to avoid damaging server hardware and consider the Intel® Xeon® E3 processor to help save on your electricity bills. 9 Do check what built-in security packages are available. Ensure that your server is protected. Built-in security1 helps you save on getting add on security packages.
