• Restrict subversion to only allow certain functions

  - by Farseeker

  I'm in a bit of a situation. We have our private subversion server that we use for development, but one of our government clients is requesting access to our commit logs so that they can get an up-to-date picture of what we've been doing on the system. I don't have a problem with them reading our commit logs, but what I do have a problem with is them having access to our source code - they can't have read or write. The obvious solution is to do an svn log ourselves and give them an export, but they want direct SVN access as they apparently have an auditing solution that will import the svn log command automagically. So, is there a way I can set up access to a subversion repo and deny them access to everything except svn log? I don't care if I have to set up a virtualhost just for this, but it has to be done over http(s). We're also using LDAP for authentication if that makes any difference.

• Automatic profile load on boot

  - by AnthonyW

  Is there any way to configure a computer to login automatically at bootup and then IMMEDIATELY switch users? The purpose is to trigger the profile loading process for the assumed user so that when they go to login, their profile loads instantaneously. Yet, the immediate user switch means that the login password is still required before any actual use. A few of the attempts I have made require storing the password in plain-text for the system to use. Needless to say that is undesireable. I have been looking for this solution for years; if anyone knows of a better solution to skinning this cat I am all ears. EDIT: tsdiscon command will Lock the workstation.

• SQL Server Data Type Precedence

  I am executing a simple query/stored procedure from my application against a large table and it's taking a long time to execute. The column I'm using in my WHERE clause is indexed and it's very selective. The search column is not wrapped in a function so that's not the issue. What could be going wrong?

• Converting obj data to CSS3D

  - by Don Boots

  I found a ton of formulae and what not, but 3D isn't my forte so I'm at a loss of what specifically to use. My goal is to convert the data in an 3D .obj file (vertices, normals, faces) to CSS3D (width, height, rotateX,Y,Z and/or similar transforms). For example 2 simple planes g plane1 # simple along along Z axis v 0.0 0.0 0.0 v 0.0 0.0 1.0 v 0.0 1.0 1.0 v 0.0 1.0 0.0 g plane2 # plane rotated 90 degrees along Y-axis v 0.0 0.0 0.0 v 0.0 1.0 0.0 v 1.0 1.0 0.0 v 1.0 0.0 0.0 f 1 2 3 4 f 5 6 7 8 Could this data be converted to: #plane1 { width: X; height: Y; transform: rotateX(Xdeg) rotateY(Ydeg) rotateZ(Zdeg) translateZ(Zpx) } #plane2 { width: X; height: Y; transform: rotateX(Xdeg) rotateY(Ydeg) rotateZ(Zdeg) translateZ(Zpx) } /* Or something equivalent such as transform: matrix3d() */ In summary, while this may be too HTML/CSS-y for game development, the core question is how to get the X/Y/Z-rotation of a 4 point plane from it's matrix of x,y,z coordinates?

• Which is better? Native App or hybrid App?

  - by Prabakaran

  I want to develop a simple App for iOS, Android and windows phone. I just wondered that a simple HTML5, JS and CSS combination can work in all of these platforms. I want to know which one will be efficient? No problem with time and coding. But if i can achieve everything with HTML5-JS itself, i will chose Hybrid development. I want to know the major difference between the Native and Hybrid Development with example(I know that the main difference is HTML5-JS supports cross platform). Note : I am not making a game app.

• Can a mapped network drive be reconnected from the command line?

  - by Stephen Jennings

  On a daily basis I find myself in the Windows command prompt needing to access a network drive that is mapped but disconnected. I have yet to find a command that will reconnect this drive without unmapping and remapping (which leads to a password guessing game, since I don't own these computers). I would also like to be able to script this so every night the drive is reconnected if it has become disconnected somehow. The fastest solution I currently have is to: Type "start." to open explorer, Alt-D to focus the address bar, type the drive letter I want and press enter, and wait for it to display the drive contents, then finally, close explorer and go back to the command prompt. I know it's a minor inconvenience, but I'm often doing this through a slow VNC or PCAnywhere connection where doing anything through GUI is awful, so I'm just wondering if there's a better solution.

• Windows file Sync

  - by Deane Venske

  So I have a big problem at the moment. Trying to find a reliable solution for syncing 2 windows IIS servers. I need to keep the web content imaged on both. Now I have been trying to use Rsync to this point, but unfortunately file permission errors are a nightmare to manage this way. I'm testing out dropbox, but the performance sucks. I'm more familiar with Linux stuff and I've used Rsync in the past but isn't there a native windows solution that will work?

• hypertext for research notes [closed]

  - by user967543

  I keep lots of notes as I work - code snippets, TODO lists, account details, links, comments. I currently use plain text files for this - very simple and robust but a bit last-century. I would like features similar to HTML - e.g. to embed pictures, formatting, and crucially hyperlinks within my notes. One particular use-case is an implementation of Getting Things Done - more or less, a collection of hierarchical TODO lists, which I'd implement with hyperlinks between tasks. Most WYSIWYG HTML editors seem to be aimed at web designers, creating beautiful pages for professional websites. Is there a simple tool / editor more appropriate for how I want to use it? (or advice from anyone doing the same)

• xen 4.0 squeeze fails to start guests with: launch_vm: SETVCPUCONTEXT failed

  - by mcr

  As Chris Benninger says over at: http://www.benninger.ca/?p=58 lots and lots of people have the problem with Squeeze and xen4.0 telling them: launch_vm: SETVCPUCONTEXT failed (rc=-1) but nobody seems to know what the solution is. I don't know either, but at least here, a solution might get recorded. In my case, I can start one guest machine. An identical configuration for a second machine fails. Whichever one I start first, is the one that runs, the other gets the error. I've got at least a dozen other systems (at my work) running great with Squeeze and 64-bit XEN, but not this new machine at home.

• Raid1+0: create stripe over two /dev/mdx on partition or not?

  - by Chris

  Given that I haven't found a way to define how a Raid10 is created with mdadm, i went the Raid1+0 solution. How to display/define Mirror/Stripping pairs with mdadm mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sda1 /dev/sdf1 mdadm --create /dev/md1 --level=1 --raid-devices=2 /dev/sdg1 /dev/sdh1 mdadm --create /dev/md10 --level=0 --raid-devices=2 /dev/md0 /dev/md1 My question is about the stripe. For the mirror I create a primary partition over the full HD and set partition type to FD. So, should I do the same for the Stripe? Create partition on /dev/md0 and /dev/md1 (primary over full 'HDD', set partition type correctly) and then do the stripe on the partition? Is there a correct way here or are there any advantages/disadvantages to a solution? Thank you

• Architecture for dashboard showing aggregated stats [on hold]

  - by soulnafein

  I'd like to know what are common architectural pattern for the following problem. Web application A has information on sales, users, responsiveness score, etc. Some of this information are computationally intensive and or have a complex business logic (e.g. responsiveness score). I'm building a separate application (B) for internal admin tasks that modifies data in web application A and report on data from web application A. For writing I'm planning to use a restful api. E.g. create a new entity, update entity, etc. In application B I'd like to show some graphs and other aggregate data for the previous 12 months. I'm planning to store the aggregate data for each month in redis. Some data should update more often, e.g every 10 minutes. I can think of 3 ways of doing this. A scheduled task in app B that connects to an api of app A that provides some aggregated data. Then app B stores it in Redis and use that to visualise pages. Cons: it makes complex calculation within a web request, requires lot's of work e.g. api server and client, storing, etc., pros: business logic still lives in app A. A scheduled task in app A that aggregates data in an non-web process and stores it directly in Redis to be accessed by app B. A scheduled task in app A that aggregates data in a non-web process and uses an api in app B to save it. I'd like to know if there is a well known architectural solution to this type of problems and if not what are other pros/cons for the solution I've suggested?

• Migrating to a new server

  - by KThompson

  I was asked by a client to move a website to a new server. Normally I would make a local copy by downloading it and then uploading it to the new server after making any necessary configurations of course. This particular client has like 1 million images ranging up 1MB and I still haven't found a solution as to how to move these properly. I have tried zipping them on the server first but the file gets too big and it seems to just stop. Anyway, the client told me he can set up a "portal" so I don't have to download and re-upload the files. I have never heard of this no can I find what this is. Any of you know something that fits this description or solution to my image problem? Thanks in advance

• 8GB, but have to run Windows Xp (32 Bit). Anything I can do with the additional memory?

  - by user12889

  I ordered a new computer with 8GB RAM with the plan to run Windows 7, 64Bit. Turns out now, that I need to run a 32Bit OS (XP or 7) due to some software which does not run on 64Bit yet (not even with any of the available compatibility settings / modes). Is there anything I can do with the memory above 4GB in this scenario? I'm willing to consider creative solutions like running a hypervisor under XP that offers the memory as a RAM-Disk for swapping etc. ? The software that does not run on 64Bit is CISCO VPN (there seems to be a half-working solution for that) and CISCO IP phone / webcam integration "CISCO Unified Video Advantage" (there is apparently no solution for that).

• On Developing Web Services with Global State

  - by user74418

  I'm new to web programming. I'm more experienced and comfortable with client-side code. Recently, I've been dabbling in web programming through Python's Google App Engine. I ran into some difficulty while trying to write some simple apps for the purposes of learning, mainly involving how to maintain some kind of consistent universally-accessible state for the application. I tried to write a simple queueing management system, the kind you would expect to be used in a small clinic, or at a cafeteria. Typically, this is done with hardware. You take a number from a ticketing machine, and when your number is displayed or called you approach the counter for service. Alternatively, you could be given a small pager, which will beep or vibrate when it is your turn to receive service. The former is somewhat better in that you have an idea of how many people are still ahead of you in the queue. In this situation, the global state is the last number in queue, which needs to be updated whenever a request is made to the server. I'm not sure how to best to store and maintain this value in a GAE context. The solution I thought of was to keep the value in the Datastore, attempt to query it during a ticket request, update the value, and then re-store it with put. My problem is that I haven't figured out how to lock the resource so that other requests do not check the value while it is in the middle of being updated. I am concerned that I may end up ticket requests that have the same queue number. Also, the whole solution feels awkward to me. I was wondering if there was a more natural way to accomplish this without having to go through the Datastore. Can anyone with more experience in this domain provide some advice on how to approach the design of the above application?

• What steps are required to get DB2 working again after renaming the Windows XP system it was running on?

  - by Suppressingfire

  I think this is a fairly well known problem, but I haven't found a really solid solution to add to my toolbox. Here's the sequence of steps that leads to the problem: Install Windows (e.g., XP), naming the system XXX Install DB2 and create some databases Rename the system from XXX to YYY (via the System control panel's Computer Name tab Reboot and find DB2 unable to start How can I get DB2 up and running again without having to reinstall it and without having to rename the system back to XXX? I did find a blog post that hints at some registry values to tweak, but I'm hoping the SF community can come up with a solution in which I can have more confidence.

• How can I ensure reasonably spaced out enemies

  - by Samuraisoulification

  I have a simple javascript game and I'm initializing their positions on the y axis using random numbers. How can I ensure that they are reasonably spaced apart? My simple algorithm is: y = (Math.random()*1000%600); However I frequently get enemies almost directly on top of each other. This is a huge problem for the game, since it's a word game and the enemies have text on their center, that if overlapped makes them impossible to kill since you can't see the words. Any advice would be appreciated! I'm pretty new to making games in general so this has all been a learning experience for me!

• What video format(s) should be used to serve Macs, PCs, and Mobile Devices?

  - by Jeffrey Blake

  In 2007, I started a site based on streaming and downloading poker strategy videos. At that point in time, the best solution I came up with for supporting users of Macs and PCs was to provide the videos in both WMV and FLV formats. Later we added an M4V version to support iPhones/iPods. Obviously, things have changed a bit since that time. I would like to revisit our format decision to see if there is anything better that we could offer, preferrably with wider support among all devices (so that we can reduce the number of formats offered, if possible). Is FLV + WMV + M4V the best solution? Is there something else we should consider? What about Android devices?

• Editing remotely the PHP files on a Centos server

  - by Alex2012

  I have a intranet web server (Centos 6, Apache, PHP) to which I would like to give access to a developer. He will connect by remote desktop from Windows 7 to Ubuntu 12.4 and from here by SSH to /var/www/html folder where it has to create and edit the files. This solution was chosen because: - I could not make a remote desktop connection from Windows to Centos - The web developer need some editor for PHP files and is not allowed to install software on Windows 7 machine - it is more a test solution ( we are all learning to use Linux). When the developer is connected from Ubuntu to Centos by SSH (SFTP) he could save the changes only if on Centos the account used to connect has ownership to that folder. Can you please tell how can I give all required rights. I tried different solutions found on Internet but without to much success. Are there other way to connect to Centos server?

• Would I benefit changing from PHP to Node.js (in context)

  - by danneth

  The situation: We are about to roll out what is essentially a logging service. As we are rather PHP heavy, the current implementation use it. We will have about 200 computers (most on the same network) that will each send, via HTTP POST, around 5000 requests/day. With each request containing about 300 bytes of data. The receiving end is hosted at Amazon and is a very simple PHP form with some simple validation that puts everything in a database. Now, I've recently been introduced to Node.js and I'm curious as to if it would be a good fit for the backend here. Granted I could easily build something to test this. But since I haven't fully grasped the async-methology I would really like someone with experience to explain it to me.

• Top down or bottom up approach?

  - by george_zakharov

  this is the closest I think I can get to define my problem. I'm an interface designer and now I'm working with a team of programmers to develop a new CMS for a heavy media site. I'm sorry if it's a very, very dumb question to ask here, but I really need some help. As I've started developing a specification list for a prototype it turned out a very big one. I do realize now that the client-side will be JS heavy, with lots of DnD and other "cool designer stuff". The CMS will even include a small project management system for its users, nothing big like Basecamp, but with a live feed of comments etc. The problem is the the team has now separated. Someone is proposing the existing backend solution used in other CMS, someone is proposing to rewrite everything from scratch. The point to keep the code is that it is faster, the point to rewrite is to make it better for the proposed design (include Node.js and other stuff I don't actually get). The question is — can the UI specs influence back-end? The guys that propose to use the existing solution did everything with the Yii framework (as far as I know), and they say that everything on server is not affected by this "interface coolness". Others say that it does, that even autosave can't work without server load. Please, if this is really incomprehensible, again, I'm sorry, and I'll happy to clarify it after your questions. Thanks in advance

• List files recursively and sort by modification time

  - by Problemaniac

  How do I list all files under a directory recursively and sort the output by modification time? I normally use ls -lhtc but it doesn't find all files recursively. I am using Linux and Mac. ls -l on Mac OS X can give -rw-r--r-- 1 fsr user 1928 Mar 1 2011 foo.c -rwx------ 1 fsr user 3509 Feb 25 14:34 bar.c where the date part isn't consistent or aligned, so a solution have to take this into account. Partial solution stat -f "%m%t%Sm %N" ./* | sort -rn | head -3 | cut -f2- works, but not recursively.

• Can i use a Windows 2008 r2 Cluster for file redundancy

  - by JERiv

  I'm researching a sever clustering architecture as a redundancy and backup solution for a client, and something that isn't made clear is whether or not i can use server clustering to replace a file server with backup solution. Forgive my Elementary understanding of server clustering but supposing: 2 Sites (NJ, CA) Identical Servers at each site setup as a Remote Site Cluster nodes with Windows Enterprise server 2008 r2 Services: File, Terminal, AD, and maybe DNS Will the following will be true: Files (including data drives) will be synced between the two servers eliminating the need for third party backup/mirroring software to sync/backup files. Also supposing i use roaming profiles w/ folder redirection; How will client computer in the WAN access their data through the cluster (i.e. will they automatically choose the best route)
