  • Where is a good place/way to store Windows config files for Python scripts?

    - by thornomad
    I have a script/program I am working on that requires a configuration file (I am using ConfigParser). On linux, I will default to store these variables in ~/.myscript using the os.getenv('HOME') function. With Windows, I know I can use os.getenv('USERPROFILE') to find the User's "home" directory, however, is it a good idea to save a hidden file that way (ie, with the name .myscript)? I don't use Windows, obviously, but wanted to be smart about it for those who do. Is there a standard place/way to store these config variables on Windows?

  • Is PNG the most economically sound file format to store pictures in?

    - by raoulsson
    I am looking for an economically sound solution to store pictures long time. I read about the PNG file format that it has superior characteristics compared to JPEG, namely in these categories: no patents, no licenses, no royalities no quality loss yet compressed I have a lot of big ESP's from PhotoShop that contain tons of metadata, like layers and color profiles that I don't need to store (those were handy for the designer, when he worked with it). I want to convert these images without that hidden data, to a new target file format. Another side condition to my question is that the target file format has to be displayable in the browser. So I guess my options are limited anyway: GIF, JPEG, PNG. Am I missing something or is PNG the best fit for my case?

  • What would be the best schema to store the 'address' for different entities?

    - by Cesar
    Suppose we're making a system where we have to store the addrees for buildings, persons, cars, etc. The address 'format' should be something like: State (From a State list) County (From a County List) Street (free text, like '5th Avenue') Number (free text, like 'Chrysler Building, Floor 10, Office No. 10') (Yes I don't live in U.S.A) What would be the best way to store that info: Should I have a Person_Address, Car_Address, ... Or the address info should be in columns on each entity, Could we have just one address table and try to link each row to a different entity? Or are there another 'better' way to handle this type of scenario? How would yo do it?

  • In CQRS (event-sourced), do you need a global sequence counter in the event store?

    - by Jon M
    In trying to get my head around CQRS (and DDD in general) I have come across situations when two events occur on different aggregates but the order of them has domain meaning. If so then they could happen so close together that a timestamp (as used by the sample implementations I have seen) cannot differentiate them, meaning the event store doesn't contain a 'complete' representation of the domain as there is ambiguity over the order in which events occurred. As an example, the domain could fire a CustomerCreatedEvent which applies to the Customer aggregate, and then a CustomerAssignedToAgent event on the Agent aggregate. The CustomerAssignedToAgent event doesn't make sense if it occurs before the CustomerCreatedEvent, but typically both of these might be fired as a result of one operation which makes it likely that the timestamps would effectively be the same. So am I just modelling things badly? Should there ever be a situation where the sequence of events across different aggregates is important? Or should you keep a global sequence number on your event store, so that you can identify the exact sequence in which events occurred?

  • Where and how does Kindle Cloud Reader store downloaded books, on a Windows 7 system?

    - by einpoklum
    I use Firefox and sometimes Chrome, on Windows 7. Amazon's in-browser Kindle Cloud Reader lets you "download" books for local/offline viewing. Where are these stored, given my OS+browser combination? I've searched the Users subdirectory for my user, and could not find a relevant (separate) file in there, specifically not in the Firefox and Chrome profile directories. To clarify, the files are obviously not downloaded as-is and are stored in some potentially-obfuscated format, possibly in the browser's local store and possibly elsewhere. The question is, where and how exactly? (This was the first of this question, but wasn't answered there since it was not the main focus of the question.)

  • Do I have to store a TcpClient even though I only care about its stream?

    - by mafutrct
    A new instance of a TcpClient connects to a remote host. Its NetworkStream is retrieved and stored. Do I have to store the TcpClient itself as well to make sure it is not garbage collected? In case you're going to answer "You have to store it to be able to dispose it": In my specific case, the TcpClient is usually living for a long time (app lifetime), so disposing it is not really a must. However, I agree that, in general, it has to be stored just to be able to call Dispose.

  • How to store Hierarchical K-Means tree for a large number of images, using Opencv?

    - by AquaAsh
    I am trying to make a program that will find similar images from a dataset of images. The steps are 1)extract SURF descriptors for all images 2)store the descriptors 3)Apply knn on the stored descriptors 4)Match the stored descriptors to the query image descriptor using KNN Now each images SURF descriptor will be stored as Hierarchical k means tree, now do I store each tree as a separate file or is it possible to build some sort of single tree with all the images descriptors and updated as images are added to dataset. This is the paper I am basing the program on www.ijest.info/docs/IJEST10-02-03-13.pdf.

  • How i store the images pixels in matrix form?

    - by Rajendra Bhole
    Hi, I developing an application in which the pixelize image i want to be store in matrix format. The code is as follows. struct pixel { //unsigned char r, g, b,a; Byte r, g, b; int count; }; (NSInteger) processImage1: (UIImage*) image { // Allocate a buffer big enough to hold all the pixels struct pixel* pixels = (struct pixel*) calloc(1, image.size.width * image.size.height * sizeof(struct pixel)); if (pixels != nil) { // Create a new bitmap CGContextRef context = CGBitmapContextCreate( (void*) pixels, image.size.width, image.size.height, 8, image.size.width * 4, CGImageGetColorSpace(image.CGImage), kCGImageAlphaPremultipliedLast ); NSLog(@"1=%d, 2=%d, 3=%d", CGImageGetBitsPerComponent(image), CGImageGetBitsPerPixel(image),CGImageGetBytesPerRow(image)); if (context != NULL) { // Draw the image in the bitmap CGContextDrawImage(context, CGRectMake(0.0f, 0.0f, image.size.width, image.size.height), image.CGImage); NSUInteger numberOfPixels = image.size.width * image.size.height; I confusing about how to initialize the 2-D matrix in which the matrix store data of pixels.

  • Where Windows 8 store data of things I recently changed?

    - by user1769787

  • Where can I store driver files so that Windows sees them when it 'searches automatically' for them?

    - by qroberts
    I am in the process of creating a few generic images and I have downloaded all the drivers for all the models of machines we use here. I can extract these drivers to any location but I am not sure where Windows looks when it is searching for drivers. Is there a driver store somewhere in Windows that it searches through? These images will be created for: Windows XP, Windows 7 x86/x64 Are the locations different between Windows XP and Windows 7? Are they different if the OS is x64 based? I know Windows likes to differentiate 32/64bit software all over the place, not sure if they do the same with driver stores.

  • Our company has 100,000s+ photos, how to store and browse/find these efficiently?

    - by tobefound
    We currently store our photos in a structure like this: folder\1\10000 - 19999.JPG|ORF|TIF (10 000 files) folder\2\20000 - 29999.JPG|ORF|TIF (10 000 files) etc... They are stored on 4 different 2TB D-link NASes attached and shared on our office network (\\nas1, \\nas2, and so on...) Problems: 1) When a client (Windows only, Vista and 7) wishes to browse the let's say \\nas1\folder\1\ folder, performance is quite poor. A problem. List takes a long time to generate in explorer window. Even with icons turned off. 2) Initial access to the NAS itself is sometimes slow. Problem. SAN disks too expensive for us. Even with iSCSI interface/switch technology. I've read a lot of tech pages saying that storing 100 000+ files in one single folder shouldn't be a problem. But we don't dare go there now that we experience problems on a 10K level. All input greatly appreciated, /T

  • iOS Development: Can I store an array of integers in a Core Data object without creating a new table to represent the array?

    - by BeachRunnerJoe
    Hello. I'm using Core Data and I'm trying to figure out the simplest way to store an array of integers in one of my Core Data entities. Currently, my entities contain various arrays of objects that are more complex than a single number, so it makes sense to represent those arrays as tables in my DB and attach them using relationships. If I want to store a simple array of integers, do I need to create a new table with a single column and attach it using a one-to-many relationship? Or is there a more simple way? Thanks in advance for your wisdom!

  • Is there any mechanism provided by Apple Store to make the user sign-up to my website before he/she

    - by Lucky
    I am creating an iphone application that requires the users to have an account at my website. But if i have to distribute it through apple store, how should I make the users of this Iphone Application first create an account with my website. There could be a few options like : 1) Ask the user to create an account when he/she tries to run the application on iphone. 2) Provide a 'Sign-Up' page in the Iphone application itself. My question is "Is there any mechanism provided by Apple Store to make the user sign-up to my website before he/she can download the application". Kindly give in your suggestions for the same. Which would be the best approach for solving my problem. Thanks, LG

  • Should business services cross bounded contexts?

    - by Paul T Davies
    Firstly, I am following the convention that a bounded context is synonymous to a department, or possibly one department has 1 to many bounded contexts. We have a client consultancy department that has a Documentation Service. Documents are stored in the Document Store Service (which is where all documents in the company are stored - it is a utility service), and the Documentation Service stores information about that document (a business service). As it was designed for the client consultancy, it is information relevant to them. Now health and safety need somewhere to store information about a document. This is different information to client consultancy, but I have been instructed to extend the existing service to account for this extra information. I feel this service is now crossing a bounded context. My worry is that all departments will eventually store there information in here and the service will become bloated, trying to be all things to all departments. Each document record will only store a subset of the information because it will only belong to one department. It will get worse when different departments want to store the same information but refer to it in a diferent ways, or when two departments want to store different information that they refer to in the same way. In my understanding, this is exactly the reason for bounded contexts. I feel each department should have it's own business service for information about a document, but use the same utility service to actually store the document. What would be the correct approach?

  • Data Store/Volume disconnecting. How to resume copy of VMDK?

    - by Serge
    I'm having an issue with my ESXi 4.1 hosts losing the datastore with FC SAN after a power outage. All 3 hosts disconnect so it's definitely a SAN issue. I've tried to resolve the issue on the SAN side with the SAN software support and Adaptec hardware support. No luck there. So I'm stuck with a SAN that will randomly disconnect the volume. I need to get the virtual machines (VMDK files) from the datastore. The problem is I can only get 5-20% before the data store disconnects. I have backups that are slightly older that I can use to replicate the VMDK differences to. What has not worked so far: Powering up the VMs, will boot up for 5-15 minutes then freeze vCenter migrate or clone of VM, will fail after similar period of time vCenter copy/paste of VMDK. Was able to get one 30GB VMDK and no luck after that. vMware Data Recovery. Fails at low %, can't resume, so next backup starts from begining. Veeam Backup & Recovery. Same as above, no resume function. If I can just find a backup solution that will resume from the failed spot that would solve my issue. Anyone have any ideas that I could try? EDIT 1 The SAN is Open-E DSS 6 running on a Supermicro 24 drive enclosure with 4 port Qlogic FC. Adaptec 52445 RAID card.

  • How to store Movies on a separate volume from the iTunes media folder?

    - by Manca Weeks
    I have a rather enormous Music collection. The music itself is approaching the 1TB mark. I am storing that on an external drive already. My iTunes library files are in their default location (/Users/me/Music/iTunes). My iTunes media folder is on an external drive /Volumes/iTunes/iTunes Music This has been working as expected. Now I would like to store just the contents of the Movies folder in the iTunes media folder on a separate drive. Apparently, iTunes doesn't like aliases or symlinks. I saw somewhere that one could mount a volume in a different directory than the default /Volumes. I would like to permanently mount my new Movies volume in the directory /Volumes/iTunes/iTunes Music/Movies. I know there is a command to do this, but how does one configure Mac OS 10.6.4 to always automatically mount that volume in this directory? I hope someone can enlighten me... If I find a solution, I can finally import all my movies into iTunes and be able to search them and stuff - it would be a dream. Thanks, M

  • How do I set up postfix to store e-mail in a file instead of relaying it?

    - by GomoX
    I want to run a staging copy of a production server on a local environment. The system runs a PHP application, which sends e-mail to customers in various scenarios and I want to make sure no e-mail is ever sent from the staging environment. I can tweak the code so it uses a dummy e-mail sender, but i'd like to run the exact same code as the production environment. I can use a different MTA (Postfix is just what we use in production), but I'd like something that is easy to set up under Debian/Ubuntu :) So, I'd like to set up the local Postfix install to store all e-mail in (one or more) files instead of relaying it. Actually, I don't really care how it's stored as long as it's feasible to check the e-mail that was sent. Even a set up option that tells postfix to keep the e-mail in the mail queue would work (I can purge the queue when I reload the staging server with a copy from production). I know this is possible, I just haven't found any good solution online for what seems like a fairly common need. Thanks!
