  • What does SVN do better than git?

    - by doug
    No question that the majority of debates over programmer tools distill to either personal choice (by the user) or design emphasis, i.e., optimizing design according to particular uses cases (by the tool builder). Text Editors are probably the most prominent example--a coder who works on a Windows at work and codes in Haskell on the Mac at home, values cross-platform and compiler integration and so chooses Emacs over Textmate, etc. It's less common that a newly introduced technology is genuinely, demonstrably superior to the extant options. I wonder if this is in fact the case with version-control systems, in particular, centralized VCS (CVS, SVN) versus distributed VCS (git, hg)? I used SVN for about five years, and SVN is currently used where I work. A little less than three years ago, I switched to git (and gitHub) for all of my personal projects. I can think of a number of advantages of git over subversion (and which for the most part abstract to advantages of distributed over centralized VCS), but I cannot think of one contra example--some task (that's relevant and arises in a programmers usual workflow) that subversion does better than git. The only conclusion I have drawn from this is that I don't have any data--not that git is better, etc. My guess is that such counter-examples exist, hence this question.

  • Vaadin Calendar events not shown if overnight [migrated]

    - by B_B
    In my vaadin project there is the possibility to create events that are shown by the calendar. It does works, except when the event is overnight, let's say the night from 23th to 24th, and the calendar shows as only day the 24th. In this case the part of the event that belongs to the 24th is supposed to be shown, but it is not. When I switch to weekly view, the event is shown properly. Here is the function where I get the data and use a container for the calendar: /* Fill Calendar from database */ void updateData() { final BeanItemContainer<TypeReservationEvent> container = new BeanItemContainer<TypeReservationEvent>(TypeReservationEvent.class); Map<String, Object> parameters = new HashMap<String, Object>(); parameters.put("roomParent",chosenRoom); String query = "SELECT DISTINCT res FROM EntityReservation res, EntityRoom r, EntityTable rt WHERE res.tableId = rt.id " + "AND rt.roomParent =:roomParent"; reservationList = facade.list(query, parameters); for(EntityReservation rt : reservationList) { container.addBean(new TypeReservationEvent(rt)); } container.sort(new Object[]{"start"}, new boolean[]{true}); cal.setContainerDataSource(container, "caption", "description", "start", "end", "styleName"); // Force calendar to refresh if(selectCalViewType.getValue() == chooseWeeklyView) { setViewType(calViewType.DAILY); setViewType(calViewType.WEEKLY); } else if (selectCalViewType.getValue() == chooseDailyView) { setViewType(calViewType.WEEKLY); setViewType(calViewType.DAILY); } } TIA

  • Why some recovery tools are still able to find deleted files after I purge Recycle Bin, defrag the disk and zero-fill free space?

    - by Ivan
    As far as I understand, when I delete (without using Recycle Bin) a file, its record is removed from the file system table of contents (FAT/MFT/etc...) but the values of the disk sectors which were occupied by the file remain intact until these sectors are reused to write something else. When I use some sort of erased files recovery tool, it reads those sectors directly and tries to build up the original file. In this case, what I can't understand is why recovery tools are still able to find deleted files (with reduced chance of rebuilding them though) after I defragment the drive and overwrite all the free space with zeros. Can you explain this? I thought zero-overwritten deleted files can be only found by means of some special forensic lab magnetic scan hardware and those complex wiping algorithms (overwriting free space multiple times with random and non-random patterns) only make sense to prevent such a physical scan to succeed, but practically it seems that plain zero-fill is not enough to wipe all the tracks of deleted files. How can this be?

  • No display but video card fans spins

    - by Marc
    Since I moved my computer there's no display when I plug my screen in the video card but works fine in the mother board. I tried reseting the cmos, but I still have the same problem. The fans are spining and there's a light from the card. I tried the DVI ports and the HDMI Here's my build. I have it for 2 months and everything was working fine. Do you think it's the video card? Asus p8z68-v pro gen3 Intel i7 2600k 120 GB OCZ Agility 3 16 GB RAM Blue Corsair DDR3 Asus GTX 570 H80 Corsair liquid cooling XFX PRO750W 80Plus bronze power supply EDIT That's why And I can't push more cause the card is on this Thank you everyone! I fixed it by pushing the mobo from the other side of the case and now it fits.

  • How do I install the nvidia driver for a GeForce 9300M?

    - by Alex
    Yesterday i've installed ubuntu 11.04 (instead of 10.10). And i need to install nvidia driver which supports opengl 3.3 In 10.10 i did it in a such way: Ctrl+alt+f1 login sudo /etc/init.d/gdm stop sudo sh driver.run startx Not it doesn't work. Because ctrl+alt+f1 doesn't show login screen. Just only black screen. I've googled this problem. Some people have it but no one knows how to solve. Sometimes people say that it is connected with video card or driver. But i have GeForce 9300M G, and i've activated a standard driver. Anyway, it worked in 10.10, but doesn't work now. The main problem is that i need to kill xserver to install this driver. killing the process just only restarts xserver. Also, I've tried to /etc/init.d/gdm stop in GUI-console. It says that "Fake initctl,doing nothing". Google didn't helped in this case too. Any ideas to install that driver?

  • How do you keep up with Nagios/Capistrano configs when using EC2?

    - by imaginative
    I use Amazon EC2 for my mobile app. Depending on load of the application at a given time, I might spawn new instances and then take them down when load is lower to save costs. How does one keep up with Nagios configurations for such a dynamic environment? When one deals with managed hardware, configuration files are predictable. In this case Nagios, Capistrano and a bunch of other configuration files would need to be added. Capistrano needs to know where to deploy a new build to for an app server. Nagios needs to know to remove an existing instance or add a new instance for monitoring. Nagios also needs to know if a node was intentionally taken down or if the host is down due to error. How is this done with the wonderful world of VPS/dynamic instances?

  • Sorting Algorithm : output

    - by Aaditya
    I faced this problem on a website and I quite can't understand the output, please help me understand it :- Bogosort, is a dumb algorithm which shuffles the sequence randomly until it is sorted. But here we have tweaked it a little, so that if after the last shuffle several first elements end up in the right places we will fix them and don't shuffle those elements furthermore. We will do the same for the last elements if they are in the right places. For example, if the initial sequence is (3, 5, 1, 6, 4, 2) and after one shuffle we get (1, 2, 5, 4, 3, 6) we will keep 1, 2 and 6 and proceed with sorting (5, 4, 3) using the same algorithm. Calculate the expected amount of shuffles for the improved algorithm to sort the sequence of the first n natural numbers given that no elements are in the right places initially. Input: 2 6 10 Output: 2 1826/189 877318/35343 For each test case output the expected amount of shuffles needed for the improved algorithm to sort the sequence of first n natural numbers in the form of irreducible fractions. I just can't understand the output.

  • How can we implement network search for Windows AND OS X clients?

    - by michielvoo
    We have a network with Windows 7 and OS X (10.5 and 10.6) computers. Our servers run on Windows Server 2003 (1 Small Business Server, 2 Standard). We need to be able to search through about 15.000 - 30.000 documents in our archives. The best solution would be if users can search directly from the Windows menu (on Windows 7) or the Spotlight menu (on OS X 10.5 and 10.6). Also good would be if users can search directly from the search bar in their browsers, or by first visiting a site with the search form. In case the users search through the browser, it's important they they are able to open a file in the search results just by clicking on it. I have tested Microsoft Search Server Express, but it doesn't meet the requirements (no OS X support, results in the browser can't be opened by clicking in anything but Internet Explorer). I have looked at Spotlight server, but that only supports OS X. Thanks!

  • Get the interface and ip address used to connect to a specific host (ip)

    - by umop
    I'm sure this has been asked and answered before, but I wasn't able to find it, so hopefully this will at least link someone to the right place. I want to find out my local interface and ip address used to reach a certain host. For instance, if I had 3 adapters connected to my box and they all three went to different networks, I'd like to know which of the three (specifically, its ip address) is used to reach my.local.intranet (in this case, it would be a vpn tunnel interface). I suspect this is a job for ifconfig or traceroute, but I haven't been able to find the correct switches. I'm running OSX 10.7 (Darwin) Thanks!

  • Office 365 - unable to deactivate

    - by Jake
    We are using Office 365 ProPlus 2013. A new user tried to activate their install and received the error that they had reached their install limit of 5 machines. Upon clicking the link the deactivate previous installs that appears in that error dialog, the user is taken to their Office software management tab. Usually, if the user has previous installs, they are listed here and the user is able to deactivate. However, in this case, previous installs do not appear and it seems something else may be the problem. I am looking for any suggestions as to what may be the problem, thanks.

  • DPM - Monitoring is green, Protection has error and Latest rec point is old. How do I interpret that?

    - by LosManos
    How do I read the DPM info in this case? Monitoring says Failed but Protection shows Ok while having a Latest recovery point from last year. Under Monitoring tab I have Failed for Source | Computer | Protection group | Start time Computer\System Protection | MyServerName | Recovery point | 2014-06-09 19:00:00 which shows me that something happened last night. But under Protection tab everything is green. Here I have Protection group member | | Protection status Protection group ..name.. Computer: MyServerName Computer\System protection Bare metal recovery OK ... Latest recovery point: 2013-12-12 06:32:54 My guess is that backup failed last night once, but succeeded later. It then found out that there hasn't been any change since sometime last year and leave it be and flags Ok.

  • Cloud services can't be reached from complex customer infrastructure

    - by Nock
    We have several services running on a cloud, they all are hosted on Windows Server 2012 R2, have public IP address and specific port. Some of our customers can't reach them because for "some reason" the ports are cut between a firewall between them and us. (some customers are using a shared internet connection in a multi tenant office and they can't change firewall communication) Well, you get it, we don't have the possibility to make all the firewall "allowing" the communication. My customers all runs Windows 7 at least. What is the best counter solution in such case, using Microsoft (Windows Server) technologies? The best would be some kind of tunneling communication or VPN, but the customer should also be able to access his/her enterprise resources. Bby the way, today we using IPSec using Windows Firewall to secure the communication, is IPSec tunneling a solution for us? Otherwise, is there a service in Windows to enable some kind of VPN between a client and a server but only for a given set of servers?

  • Linux Software Raid runs checkarray on the First Sunday of the Month? Why?

    - by mgjk
    It looks like Debian has a default to run checkarray on the first Sunday of the month. This causes massive performance problems and heavy disk usage for 12 hours on my 2TB mirror. Doing this "just in case" is bizzare to me. Discovering data out of sync between the two disks without quorum would be a failure anyway. This massive checking could only tell me that I have an unrecoverable drive failure and corrupt data. Which is nice, but not all that helpful. Is it necessary? Given I have no disk errors and no reason to believe my disks have failed, why is this check necessary? Should I take it out of my cron? /etc/cron.d# tail -1 /etc/cron.d/mdadm 57 0 * * 0 root [ -x /usr/share/mdadm/checkarray ] && [ $(date +\%d) -le 7 ] && /usr/share/mdadm/checkarray --cron --all --quiet Thanks for any insight,

  • How to optimize calls to multiple APIs at once and return as one set?

    - by Martin
    I have a web app that searches across 2 APIs right now. I have my own Restful web service that I call, and it does all the work on the backend to asynchronously call the 2 APIs and concatenate them into one result set for my web app to use. I want to scale this out and add as many other APIs as I can (currently looking at about 10 more). But as I add APIs, the call to my service gets (potentially) slower and more complex. How do I handle one API not responding ... and other issues that arise? What would be the best way to approach this? Should I create a service call for each API, that way each one is independent and not coupled to all the other calls? Is there a way on the backend to handle the multiple API calls without all the extra complexity it adds? If I go the route of a service call per API, now my client code gets more complex (and I have a lot of clients)? And it's more work for the client, and since I have mobile apps, it will cost the client more data usage. If I go one service call, is there a way to set up some sort of connection so I can return data as I get it, in case one service call hangs?

  • what to do when ctrl-c can't kill a process?

    - by Dustin Boswell
    Ctrl-c doesn't always work to kill the current process (for instance, if that process is busy in certain network operations). In that case, you just see "^C" by your cursor, and can't do much else. What's the easiest way to force that process to die now without losing my terminal? Summary of answers below: Usually, you can Ctrl-z to put the process to sleep, and then do "kill -9 process-pid", where you find the process's pid with 'ps' and other tools. On Bash (and possibly other shells) you can do "kill -9 %1" (or '%N' in general) which is easier. If Ctrl-z doesn't work, you'll have to open another terminal and kill from there.

  • Nginx save file to local disk

    - by Dean Chen
    My case is: In our China company, we have to access one web server in USA headquarter through Internet. But network is too slow, and we download many big image files. All our developers have to wait. So we want to setup a Nginx which acts as reverse proxy, its upstream is our USA web server. Question is can we make Nginx save the image files from USA web server into its local disk? I mean let Nginx act as one cache server.

  • Using Different Mappings for Uppercase and Lowercase of the Same Key

    - by cosmic.osmo
    I'm trying use AutoHotkey to map some key combinations in a way that respects upper and lowercase, but I cannot get it to work. For example: I want: AppsKey + L types "a" AppsKey + Shift + L types "b" A. I've tried these, but both combinations only give "b" ("+" appears to be the symbol for shihft): AppsKey & l::Send a AppsKey & +l::Send b B. I've tried this, but it won't compile and gives a "invalid hotkey error": AppsKey & l::Send a AppsKey & Shift & l::Send b C. I've tried this, but it won't compile and gives a "duplicate hotkey error" (which makes sense as it appears the hotkey definitions are case insensitive): AppsKey & l::Send a AppsKey & L::Send b Is this type of mapping possible in AutoHotkey? What am I missing to make it work?

  • Having the same texture data in different ID3D11Texture2D

    - by bdmnd
    Sorry if this has been answered elsewhere - I'm rather new to DX. My question concerns conservation of resources - specifically textures in VRAM. I assume that upon returning from a call to CreateTexture2D, a copy of any textures data supplied has been copied elsewhere, likely VRAM. Does DX11 have any facility for having multiple ID3D11Texture2D objects which point to the same data? This might at first seem silly, but imagine a ID3D11Texture2D which is an array of textures. In one material, an artist has chosen to blend three identically sized maps, saved on disk as A.dds, B.dds, and C.dds. Then imagine they have another material which also uses three maps, but this time A.dds, B.dds, and D.dds. The shader code knows the diffuse texture is a texture array, and also has the number of layers baked (three in each case). I would essentially like to set up just two ID3D11Texture2D objects, one for each material, but I don't want to waste VRAM for two identical copies of A.dds and B.dds. I could use explicit texture arrays, of course, but this reduces the number of resources available to the shader and can complicate code somewhat more than would otherwise be needed.

  • What video codecs have most amount of content and thus popular at present/in future?

    - by goldenmean
    Hi, I want to find out if I can get some data on the percentage wise distribution of video content, for different video codecs currently used for video encoding. I know there are different applications/use-case scenarios which have different encoder used but i want to consdier all that and have a overall usage number(%) My guess is(highest to lowest % of content) - H.264(AVC) DivX MPEG2 VP6 Where do H.263, MPEG4, VC-1, RV, Theora, etc. fit in here. How may this look like in future? PS:I would like this to be community wiki to have get wider range of inputs, if someone with privileges can do it for me please. thank you. -AD

  • Bash: Quotes getting stripped when a command is passed as argument to a function

  • How do I recover a RAID 1 volume on Mac OS X (10.7)?

    - by Avry
    I have a Synology NAS that I've set up with RAID 1. The device is set up with two drives, both the same size (i.e. 500 GB each), formatted in ext3, as a RAID 1 volume (i.e. even though the total capacity is 1TB, I effectively only get 500 GB). In the case of a device failure where I can only access one of the drives, how can I recover my data? The solution I'm looking for is something like: 'Put the working drive in an enclosure, and use <some software> to recover your data.'

  • Multiple SMTP servers in Thunderbird3

    - by ldigas
    Situation: 2 mail accounts - each with its own pop3 and smtp servers, accesed normally. Except, when using Vodafone mobile network (you know, those usb or pcmcia cards ...) in which case mails are send using Vodafone's SMTP server. I configured both accounts in thunderbird for their default servers, and then added under multiple identities, another called Name of User (mobile) for each account. And it works. Except, I don't like the fact that when I send mail using mobile smtp server it sends them under Name of User (mobile) <-- the mobile part being important. I could of course, delete that part, but then when sending mail, I'd have no way of differenting between the two. They'd both look as Name of User email@address_of_user.com. So, what would be the easiest way to solve this ? It is not a major problem, but it is annoying.

  • SSL certificates and whether a wildcard common name will support domain.com

    - by timpone
    Sorry, if this is very vendor specific but I purchased an inexpensive SSL Cert from GoDaddy. Right now everything on production is hosted off of www.domain.com. When specifying the common name would a wildcard (ie *.domain.com) cover the case of a lack of a third-level domain such as domain.com? Just to be sure, I made it for www.domain.com rather than a wildcard. If it matters, I will be using with nginx and a mod_passenger. If I want to cover everything including domain.com and staging.domain.com, www.domain.com etc, would a wildcard be the proper cert? Does the inexpensive godaddy cert (12.99 / year) cover wildcard certs (it didn't seem to for me)? Again, sorry for asking vendor specific questions and thx in advance. thx
