  • VNC Server that can be used from command line?

    - by jesusiniesta
    I'm looking for a replacement for a custom vnc server that we have been using in my company for a long time. I need a simple executable that can be run from command line by an IT Support software without the user noticing it (our application will warn the user, we don't want him to see we are using that VNC sever). I need it to support Windows and preferably also OSX. The only option I've found is UltraVNC, but I can't configure it from command line to accept loopback connections without authentication. We have already a whole VNC Viewer + VNC Repeater + Bouncers architecture, and the only missing piece is the VNC Server. Do you know any solution you could suggest me? I'm afraid I'll end up developing a new VNC server myself, may be based on an open source one. EDIT: When I said I don't want the user to notice this VNC server, I should have added that I don't want him even noticing the installation. So better if it can be installed silently or can be executed as a portable executalbe (for instance, ultravnc can be installed and ran as a service from command line, or simply executed quietly, with only a notification icon; its problem is that I can't run it without authentication).

  • What should I use to ping multiple IPs and get notified of time outs?

    - by HumanVirus
    I've been using MultiPing to ping hundreds of IPs (from access points and such) and check their performance (packet loss, latency) and uptime. The program is very easy to use, but I was wondering if someone could recommend me something that would work better and that would also work in Linux. The features I'm looking for are: Notification Types: At least desktop notifications and SMS, but it would be great if it also had e-mail, IM, or other types of notifications. (MultiPing has some of these, but they don't work too well.) Being notified about the root problem only: Since some devices are dependent on others, I'd like to be notified only about the root problem. E.g. Let's say I have A[x.x.x.222]B[x.x.x.33C[x.x.x.44]D[x.x.x.55], and B goes down, therefore C and D will also be down. Is it possible to get a notification only about B being down? Light on resources. Ideally multiplatform or at least available for both Linux and Windows. I've heard about Nagios and Shinken being used for monitoring. Would you recommend that I use something of the sort or would that be too much for my needs? If using Nagios, Shinken, or similar software is recommended, can anyone tell me what sites I should go to or what books I should get that would be good for someone who is totally new at this? I'd appreciate any suggestions.

  • Swimlane Diagram Softwares with Expand/Collapse Features

    - by louis xie
    I've been searching real hard for a software which can fulfill my needs, but to no avail. I have a swimlane diagram which is extremely huge, and almost impossible to model using Visio or any traditional swimlane software. I would need to model both the operational process, as well as the interactions within an application and between different applications. Therefore, without wasting additional effort modelling these separately, I am looking for a solution which I can combine both views together. That is, possibly one which I can expand/collapse/group/ungroup processes/subprocesses together. Take a typical credit card process for instance, a hypothetical description of the swimlane could be as such: Customer submits application form to the bank Bank Officer A receives the application form and validates that it was correctly filled Bank Officer A submits application form to Bank Officer B for processing. Bank Officer B checks credit quality of the customer through Application X. Application X submits query to Application Y to retrieve Credit Report. Application X retrieves credit report and submits to Application Z for computation of credit scores Bank Officer B validates that customer is credit worthy, and submits application to Bank Officer C for processing. The above is an over-simplified credit card request process, and a purely hypothetical one. What I'm trying to drive at is, each of the above processes have sub-processes, and I want to be able to switch between a "detailed" view and "aggregated" view. If possible, add in time dependency of the different tasks, as well. I haven't been able to find one such software which could do this.

  • Is going for a BCS the right move for me?

    - by Michel Carroll
    I'm at a fork in the road. I need somebody to give me some advice from their personal journey in IT. At the moment, I have a college diploma (2 years) in Computer Programmer, and about 2 years of professional experience in the field of software. I'm currently freelancing my programming skills to the public, and am enjoying a nice income, and the rewards of flexibly working on a variety of projects with different cool people. I'm young (21 years old), passionate about software, technology, the internet, and also business. I know if I ever want to dwell deeper into the software industry, I might have a hard time doing so without a Bachelors in Computer Science. On one side, I think I'm better off getting my BCS while I'm still young and malleable. Also, the thought of learning even more stuff in my field is really exciting to me. On the flip side, it means another 3-4 years of studying, and jeopardizing my chances of going on vacation and accumulating wealth for a long time. Considering that I'm already pretty successful with my college diploma, do you think it's a good idea for me to go get my BCS? Will it open up many more doors in the future?

  • Customizing Fantacy Remote .INI file

    - by karthik
    I am using Fantacy Remote to remote view other machines. I have attached the default .INI file that Fantacy Remote uses. When i connect to a machine, the client user should not have mouse and keyboard access of the Remote machine. It should be a View only remote connection. And i want to make the Remote viewer screen to be in full screen mode, because i dont want the user to do anything with menubars of Fatancy remote. Because this is kiosk application.

  • Expendable, Redundant, Easily recoverable

    - by MeIr
    I am desperate at this point, I have been looking for "Big storage" solution for a while on my own and I can't find anything that would suite my needs. But now push came to shove. Current situation: I have about 6TB data storage (already full) - Drobo. Yesterday Drobo died on me and it put me into bad situation - I can't recover my data without buying another Drobo. From extensive research online I realized that Drobo is not the safest bet and by now it seems very poor choice. I ordered new Drobo to try to get my data back, however I don't want to be in the same situation later and continuing using Drobo promises this event to re-occur. What I am looking for: 1) Inexpensive setup. 2) Dynamically extendable - add more drives and/or replace a drive with bigger capacity. 3) Redundant - setup against 1-3 drive failure, will depend on total number of drives. For the sake of argument let's assume for every 4 drives one should be able to fail without data loss. 4) Easy data recovery - let's say unforeseen happens, I would like to be able to recover information without buying new tools or replacements - example: new Drobo. 5) Should be USB or Network Attach Storage 6) No demand on speed. Doesn't have to be fast, I am not doing video editing on the setup. However if option exists, would be nice to have a decent speed. After thoughts: I reviewed few options and FreeNAS looks nice, but it doesn't have #2 - Dynamic extendability. There are work around with Pools but it seems a bit complicated and unnecessary. More over it seems like data safety is a big question - saw some horror stories. Please advise on what options I have and what seems like an optimal solution (if any). I don't care if it has to be Windows or Linux box or any other OS and/or software that has to run on top, but simple solution is more attractive. Thank you! P.S: Feel free to ignore "After thoughts".

  • Is proprietary vendor software required to use a wireless printer?

    - by sajee
    On Windows Vista, other than the driver, one can use a regular printer w/o any extra software, either plugged in via USB or over the network. I don't have to install extra software from the printer vendor to use the basic printer functionality. Is the same true for wireless printers? I need to install the HP 6000 wireless printer, and I hate installing vendor software other than the required drivers. So I'm wondering whether I need to install HP software on every PC that wants to use this printer? I haven't had a chance to read the manual but I'm hoping I don't have to. Can folks that have experience with wireless printers comment on whether vendor software, other than the printer driver, is required to use a wireless printer?

  • Ctrl Alt Left/Right moves mouse - how to find responsible software?

    - by Unimatrix02
    Hi, I've got a bit of a strange problem. On one of our computers, pressing ctrl + alt + left/right/up/down will move the mouse pointer on the screen, but it's not clear which software makes this happen. It interferes with other software that uses these shortcuts. I've already tried disabling some software, such as WinKey and a Kensington mouse driver, but that didn't make a difference. It's happening on a Windows XP SP3 computer by the way. Does anyone have an idea of how to find the software that traps this shortcut? Suggestions for actual (types of) software that might be doing this are welcome too. Thanks!

  • KVM guest io is much slower than host io: is that normal?

    - by Evolver
    I have a Qemu-KVM host system setup on CentOS 6.3. Four 1TB SATA HDDs working in Software RAID10. Guest CentOS 6.3 is installed on separate LVM. People say that they see guest performance almost equal to host performance, but I don't see that. My i/o tests are showing 30-70% slower performance on guest than on host system. I tried to change scheduler (set elevator=deadline on host and elevator=noop on guest), set blkio.weight to 1000 in cgroup, change io to virtio... But none of these changes gave me any significant results. This is a guest .xml config part: <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/dev/vgkvmnode/lv2'/> <target dev='vda' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </disk> There are my tests: Host system: iozone test # iozone -a -i0 -i1 -i2 -s8G -r64k random random KB reclen write rewrite read reread read write 8388608 64 189930 197436 266786 267254 28644 66642 dd read test: one process and then four simultaneous processes # dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct 1073741824 bytes (1.1 GB) copied, 4.23044 s, 254 MB/s # dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct skip=1024 & dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct skip=2048 & dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct skip=3072 & dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct skip=4096 1073741824 bytes (1.1 GB) copied, 14.4528 s, 74.3 MB/s 1073741824 bytes (1.1 GB) copied, 14.562 s, 73.7 MB/s 1073741824 bytes (1.1 GB) copied, 14.6341 s, 73.4 MB/s 1073741824 bytes (1.1 GB) copied, 14.7006 s, 73.0 MB/s dd write test: one process and then four simultaneous processes # dd if=/dev/zero of=test bs=1M count=1024 oflag=direct 1073741824 bytes (1.1 GB) copied, 6.2039 s, 173 MB/s # dd if=/dev/zero of=test bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test2 bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test3 bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test4 bs=1M count=1024 oflag=direct 1073741824 bytes (1.1 GB) copied, 32.7173 s, 32.8 MB/s 1073741824 bytes (1.1 GB) copied, 32.8868 s, 32.6 MB/s 1073741824 bytes (1.1 GB) copied, 32.9097 s, 32.6 MB/s 1073741824 bytes (1.1 GB) copied, 32.9688 s, 32.6 MB/s Guest system: iozone test # iozone -a -i0 -i1 -i2 -s512M -r64k random random KB reclen write rewrite read reread read write 524288 64 93374 154596 141193 149865 21394 46264 dd read test: one process and then four simultaneous processes # dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=1024 1073741824 bytes (1.1 GB) copied, 5.04356 s, 213 MB/s # dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=1024 & dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=2048 & dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=3072 & dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=4096 1073741824 bytes (1.1 GB) copied, 24.7348 s, 43.4 MB/s 1073741824 bytes (1.1 GB) copied, 24.7378 s, 43.4 MB/s 1073741824 bytes (1.1 GB) copied, 24.7408 s, 43.4 MB/s 1073741824 bytes (1.1 GB) copied, 24.744 s, 43.4 MB/s dd write test: one process and then four simultaneous processes # dd if=/dev/zero of=test bs=1M count=1024 oflag=direct 1073741824 bytes (1.1 GB) copied, 10.415 s, 103 MB/s # dd if=/dev/zero of=test bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test2 bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test3 bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test4 bs=1M count=1024 oflag=direct 1073741824 bytes (1.1 GB) copied, 49.8874 s, 21.5 MB/s 1073741824 bytes (1.1 GB) copied, 49.8608 s, 21.5 MB/s 1073741824 bytes (1.1 GB) copied, 49.8693 s, 21.5 MB/s 1073741824 bytes (1.1 GB) copied, 49.9427 s, 21.5 MB/s I wonder is that normal situation or did I missed something?

  • How do software projects go over budget and under-deliver?

    - by Carlos
    I've come across this story quite a few times here in the UK: NHS Computer System Summary: We're spunking £12 Billion on some health software with barely anything working. I was sitting the office discussing this with my colleagues, and we had a little think about. From what I can see, all the NHS needs is a database + middle tier of drugs/hospitals/patients/prescriptions objects, and various GUIs for doctors and nurses to look at. You'd also need to think about security and scalability. And you'd need to sit around a hospital/pharmacy/GPs office for a bit to figure out what they need. But, all told, I'd say I could knock together something with that kind of structure in a couple of days, and maybe throw in a month or two to make it work in scale. * If I had a few million quid, I could probably hire some really excellent designers to make a maintainable codebase, and also buy appropriate hardware to run the system on. I hate to trivialize something that seems to have caused to much trouble, but to me it looks like just a big distributed CRUD + UI system. So how on earth did this project bloat to £12B without producing much useful software? As I don't think the software sounds so complicated, I can only imagine that something about how it was organised caused this mess. Is it outsourcing that's the problem? Is it not getting the software designers to understand the medical business that caused it? What are your experiences with projects gone over budget, under delivered? What are best practices for large projects? Have you ever worked on such a project? EDIT *This bit seemed to get a lot of attention. What I mean is I could probably do this for say, 30 users, spending a few tens of thousands of pounds. I'm not including stuff I don't know about the medical industry and government, but I think most people who've been around programming are familiar with that kind of database/front end kind of design. My point is the NHS project looks like a BIG version of this, with bells and whistles, notably security. But surely a budget millions of times larger than mine could provide this?

  • How do you demo software with No UI in the Sprint Review?

    - by Jeff Martin
    We are doing agile software development, basically following Scrum. We are trying to do sprint reviews but finding it difficult. Our software is doing a lot of data processing and the stories often are about changing various rules around this. What are some options for demoing the changes that occurred in the sprint when there isn't a UI or visible workflow change, but instead the change is a subtle business rule on a processing job that can take 10s of minutes or even a couple of hours?

  • Why doesn't Mozilla release .deb and .rpm packages for their software?

    - by ushabtay
    i use and enjoy Firefox on my Ubuntu 10.04.2 laptop (although Firefox needs work for the Linux/Ubuntu version..) Yet i realize that in comparison to other pieces of software that have an "Ubuntu/Debian" version (.deb file, and usually .rpm files as well), i don't see it in one of the most profound assets of the FLOSS world. The Question is - Why? If Chrom/ium can - why can't they? Easier to get up-to-date software and features and so forth.. cheers,

  • Is there a term for quasi-open source proprietary software?

    - by mwhite
    Say a company wants to keep development of new features of a piece of software internal, but wants to make the source code for previous versions public, up to and including existing public features, so that other people can benefit from using and modifying the software themselves, and even possibly contribute changes that can be applied to the development branch. Is there a term for this sort of arrangement, and what is the best way of accomplishing it using existing version control tools and platforms?

However, after reading through a dreadful book full of bad advice on managing programming teams this weekend I am looking for recommendations for really good books that focus on the management side of programming (recruiting, performance measurement/management, motivation, best practices, organizational structure, etc.) and not as much on the construction of software itself. Any suggestions?

  • Are there software options (preferabbly .NET) for doing distance and speed analysis of footballers moving on video?

    - by Anonymous Type
    Editing Question for Clarity Thanks for feedback so far, very insightful. I'm not sure how far along this part of the software community is, and what if any libraries exist for me to leverage from. Heres what I'm trying to do. Problem: Take an existing video of a game of rugby league. The Rugby League field is 100 metres long, 70 metres wide, and has white line markings every 10 metres running along the width of the field, as well as along the sidelines. Each side has 13 players on the field. Players on each team have identical jerseys that normally constrast strongly against background colours (green/brown field colour) and the referee's colour (usually yellow) and the designated water runner (orange). All players have a unique number in thick white lettering on their backs for identification. Video is taken with a high definition camera. Currently only one camera is used (2D) and existing video does not contain a foreground object of fixed spatial dimensions (as suggested in one answer for comparision measurements, however I could add this to future filming sessions if it is worthwhile). The player's do not run in a straight line 50% of the time but will go sideways on on a diagonal to the play the ball. The distance measured always starts from the spot of the previous "tackle", which ends where the player stops forward movement. It is not always possible to determine the players number from the video (facing other direction, sunlight, others standing in the way of the camera). But this isn't important as the software could allow for manual inputting of unknown "runs" at a later point after analysis. Determine the distance between two points (i.e. where the player started his "run" and where he finished it). I'm guessing that this would be quite doable if I manually marked the start and end point in the video. But how would I use landmarks in the background to determine the distance (assuming the person taking the video has kept it from jerking around). Question: Do software packages or libraries exist that are specialised enough to assist with writing analysis software to determine a sports persons distance travelled based on video taken of the performance?

  • What partition PlayOnLinux and Wine software has to be installed to?

    - by user211076
    please tell I'm using Ubuntu 12.04 and if I have already created ext4 ./ (partition) and on the same volume I have ./home so if I create a separate partition ./home will the software that I install for example from Ubuntu Download Center will automatically go to ./home (partition) or still ./ (root) because I'm using PlayOnLinux and Wine and all its software only installs to ./home (file system disk) where emulated copy of Windows Xp installed also and it's a lack of space.

  • Version control of software refactoring

    - by Muhammad Alkarouri
    What is the best way of doing version control of large scale refactoring? My typical style of programming (actually of writing documents as well) is getting something out as quickly as possible and then refactoring it. Typically, refactoring takes place at the same time as adding other functionality. In addition to standard refactoring of classes and functions, functions may move from one file to another, files get split and merged or just reordered. For the time being, I am using version control as a lone user, so there is no issue of interaction with other developers at this stage. Still, version control gives me two aspects: Backup and ability to revert to a good version "in case". Looking at the history tells me how the project progressed and the flow of ideas. I am using mercurial on windows using TortoiseHg which enables selections of hunks to commit. The reason I mention this is that I would like advice on the granularity of a commit in refactoring. Should I split refactoring from functionality added always in committing? I have looked at the answers of http://stackoverflow.com/questions/68459/refactoring-and-source-control-how-to but it doesn't answer my question. That question focuses on collaboration with a team. This one concentrates on having a history that is understandable in future (assuming I don't rewrite history as some VCS seem to allow).

  • Good projects to learn OCaml and F#

    - by Yin Zhu
    After learning the basic syntax, reading some non-trivial code is a fast way to learn a language. We can also learn how to design a library/software during reading others' code. I have following lists. A Chess program in OCaml by Tomek Czajka. Hal Daumé has written several machine learning libraries in Ocaml. Including decision trees, logistic regression and SVM. All of them are near-production-quality code. A Chess Game Analysis program in F# in Microsoft Research. The above three are my favorites. Will you suggest some other sources? General purpose open source software are good, specialized open source like the three I list here are even more welcome.

  • Port scientific software to GPU and publish it

    - by Werner
    Hi, let's say that I am a physicist and that I am the master of the universe when it comes to port salready existing oftware to GPU's with 100x or more speedups. Let's say that I find that some other scientist, which does not know how to program GPU, publishes the Open Source code in his/her website of a physical simulation program, in the field I am expert on. Let's say that I realize "I can port that code to GPU", and I suggest him, but he shows no interest. My interest here is, 1) to port it to GPU, 2) to publish this result in a scientific journal related with physics and/or computer science My question for you is 1- would you proceed here to port the code to GPU (or other new arch) and publish it? 2- how would you do it and which journal do you suggest? Thanks
