• How to tell svn to not manage history for one file

  - by Prabu

  I don't know whether SVN has this feature, How do I tell svn to not maintain the history of changes for a file but it should have only the latest version of the file. Of course this is not the work of a version control, but it will be useful if I want to have some binary files within the repo without versioning.

• What technology should I use if any on top of HTTP for uploads of data to a web service?

  - by Tom Dignan

  I am writing a web service that will receive uploads from mobile clients. The data will have 4 or more text fields followed by a large binary field. What is the best standard technology to use for this, as I may make the API public in the future and want to use something that everyone likes. XML? SOAP? Just HTTP and a completely customized payload? Thanks.

• Pros and Cons of oursql [closed]

  - by S.Mark

  According to this python page, oursql looks very cool. oursql has real parameterization. oursql allows text or binary data to be streamed into the database and streamed out of the database, instead of requiring everything to be buffered in the client. oursql can both insert rows lazily and fetch rows lazily. oursql has unicode support on by default. So, Anyone start using it in the live projects and could share pros and cons over it?

• Is it possible to use multiple languages in .NET resource files?

  - by Gabe Brown

  We’ve got an interesting requirement that we’ll want to support multiple languages at runtime since we’re a service. If a user talks to us using Japanese or English, we’ll want to respond in the appropriate language. FxCop likes us to store our strings in resource files, but I was curious to know if there was an integrated way to select resource string at runtime without having to do it manually. Bottom Line: We need to be able to support multiple languages in a single binary. :)

• How do I permanently remove (obliterate) files from history?

  - by phmr

  I commited a lot of files locally (including binary files removing & adding...) and now when I try to push it takes a lot of time. Actually I messed up my local repo history. How could I avoid this mistake in the future ? Can I transform a set of local revision 1-2-3-4 to 1-2 with 2 being the final revision of the local clone ?

• How to sign XML document or verify XML document signature with C++?

  - by Budda

  Subj. I need to sign/verify in native C++ (no .NET), using private key for signing, public key for verification. I saw few examples on MSDN (http://msdn.microsoft.com/en-us/library/ms761363(VS.85).aspx) that demonstrate how to sign the document with CSP (I don't know what this means). For my case I need to create a "key" from the binary data array... can somebody help me with that? Thank you in advance.

• Python's cPickle deserialization from PHP?

  - by Ciantic

  Hi! I have to deserialize a dictionary in PHP that was serialized using cPickle in Python. In this specific case I probably could just regexp the wanted information, but is there a better way? Any extensions for PHP that would allow me to deserialize more natively the whole dictionary? Apparently it is serialized in Python like this: import cPickle as pickle data = { 'user_id' : 5 } pickled = pickle.dumps(data) print pickled Contents of such serialization cannot be pasted easily to here, because it contains binary data.

• Get Visual Studio to produce the same DLL for the same C# source

  - by JoelFan

  I noticed that when I build a given C# source to produce a DLL, the binary output is different each time. It would be helpful for our build / deployment process if this was not the case. Can I control this?

• How do you measure the effect of branch misprediction?

  - by Matt Wamboldt

  I'm currently profiling an implementation of binary search. Using some special instructions to measure this I noticed that the code has about a 20% misprediction rate. I'm curious if there is any way to check how many cycles I'm potentially losing due to this. It's a MIPS based architecture.

• Can str_replace mangle a UTF-8 encoded string if it's only given valid UTF-8 encoded strings as argu

  - by Manos Dilaverakis

  PHP's str_replace() was intended only for ANSI strings and as such can mangle UTF-8 strings. However, given that it's binary-safe would it have a problem if it was only given valid UTF-8 strings as arguments? Edit: I'm not looking for a replacement function, I would just like to know if this hypothesis is correct.

• Boost Serialization Library upgrade

  - by Konstantin

  Hello! How do I know that I can safely upgrade Boost Serialization Library on a production system without breaking compatibility with the existing data ? Is there any test that I should perform in order to be sure that all data stored in the binary format by previous version of the library will be successfully read by the new one ? Does Boost Serialization library itself guarantee some sort of compatibility between versions ?

• How do machine code instructions get transferred to the CPU?

  - by user3711789

  I'm currently investigating what the runtime of different programming languages looks like behind the scenes. For a compiled language like C, people usually give the explanation of "Code is compiled to assembly which is assembled and linked into a binary executable. The executable is then loaded into memory and the CPU interprets it." My question is how does the CPU know where to look for the next instruction to execute? Is it a memory address stored in one of the registers?
