  • Sikuli List of Functions & Operators

    - by PPTim
    Hello, I've just discovered Sikuli, and would like to see a comprehensive functions list without digging through the online-examples and demos. Has anyone found such a list? Furthermore, apparently Sikuli supports more complex loops and function calls as well, and seems to be based in Python(!!). Examples would be great. Thanks.

  • How to load another's service certificate to my WebLogic truststore?

    - by Murugan
    An online service provided me with their certificate (a pfx file) along with its password. I am looking to load that into my WebLogic 8.1 truststore in Unix. There is a truststore currently that exists in my WebLogic. I am new to this so I was wondering what was the process to add that other party's certificate to my existing WebLogic keystore. Do I need to convert the pfx file into a different for Unix?

  • Script to mirror MS SQL Server databases between 2 servers

    - by David W
    Hi I have about 200 sites each of which have 2 servers running MSSQL (2k5 at some sites, 2k8 at others) One server is production and the other is primarily there as a backup. We're rebuilding all of these servers this year and as part of that we will have to set up mirroring for ... a lot ... of databases. Some of these sites have 45 databases so mirroring them manually is going to be a huge pain. I was going to write a batch script which uses SQLCMD to backup the database and log, copies to the secondary server, restores the backup and log with norecovery, creates the endpoints and sets the partner. This in itself isn't too complicated, but i'd love to see what other people have done as i'm not very confident in catching errors using the process i've outlined above. I've seen Tools to manage sql 2008 database mirroring? Which looks really good, but the formatting is jumbled and I can't get it to work. If anyone has any other scripts they've written and are willing to share I'd be eternally grateful. Ideally I'd love to be able to use a script to ensure there are matching endpoints (same ports) on both servers, backup the database, backup the log, copy the backups to second server, restore database and log with norecovery, set the partners on both servers, and somehow confirm that the databases are linked and synchronized. Well, thanks for reading :)

  • De-duplicating backup tool on a block basis? [closed]

    - by SST
    I am looking for an (ideally free as in speech or beer) backup tool for Unix-like OS which can store deduplicated backups, i.e. only nonredundant content takes up additional space. I already looked at dirvish (my first candidate) and rsnapshot which use hardlinks to achieve deduplication on a per-file level. However, as I want to back up large files (Thunderbird mailboxes 3GB, VMware images 10GB), such file are stored again entirely even if just a few bytes change. Then there are rsync-based tools like rdiff-backup which only store deltas and a current mirror. However, as the deltas are generated against each previous mirror, it is difficult to fine-tune the retention granularity (only keep one backup after a week, etc.) because the deltas would have to be re-evaluated. Another approach is to partition content into blocks and store each block only if it is not stored yet, otherwise just linking it to the first occurrence. The only tool I know of that does this by now is obnam (http://liw.fi/obnam), and it even supports zlib-compression and gpg-encryption -- nice! But it is very slow, AFAICT. Does any one know any other, solid backup software which supports deduplication on a sub-file level, ideally with at least some management options (show/select/delete generations...)?

  • Unfamiliar Javascript Syntax

    - by user1051643
    Long and short of the story is, whilst reading John Resig's blog (specifically http://ejohn.org/blog/javascript-trie-performance-analysis/) I came across a line which makes absolutely no sense to me whatsoever. Essentially it boils down to object = object[key] = something; (this can be found in the first code block of the article I've linked.) This has proven rather difficult to google, so if anyone can offer some insight / a good online resource for me to learn for myself, I'd much appreciate it.

  • Calling a webservice in javascript

    - by user303052
    So, I am trying to make a firefox extension which will use a webservice. I was looking online to find a way to do this. I was wondering if someone could explain what the following objects/methods do: service.useService(_, _); service.<`Service Name.callService(); If there is an alternative that does not include these objects, I would be happy to hear about it. Thank you very much

  • Need to have testing server work with https: but don't have an SSL

    - by Cyrcle
    I'm working on an online store. I have it setup on my testing server. I'm having a problem where when it goes to the checkout functions it wants to start calling https pages. I don't have an SSL certificate for this server. Is there something I can do with Apache to get this to work? Mod_Rewrite perhaps? I've played a little with rewrites but haven't had any success.

  • video tag in iphone status

    - by David
    Is there any movie that actually works in iPhone/iPad safari using the video tag? We tried so many formats and code snippets. I've heard that mp4/h264 should work, but not for us. Can anyone point me to a working example online? If you know the code or specs/formats for the videotag on iphone, that would be great.

  • What are the typical methods used to scale up/out email storage servers?

    - by nareshov
    Hi, What I've tried: I have two email storage architectures. Old and new. Old: courier-imapds on several (18+) 1TB-storage servers. If one of them show signs of running out of disk space, we migrate a few email accounts to another server. the servers don't have replicas. no backups either. New: dovecot2 on a single huge server with 16TB (SATA) storage and a few SSDs we store fresh mails on the SSDs and run a doveadm purge to move mails older than a day to the SATA disks there is an identical server which has a max-15min-old rsync backup from the primary server higher-ups/management wanted to pack in as much storage as possible per server in order to minimise the cost of SSDs per server the rsync'ing is done because GlusterFS wasn't replicating well under that high small/random-IO. scaling out was expected to be done with provisioning another pair of such huge servers on facing disk-crunch issues like in the old architecture, manual moving of email accounts would be done. Concerns/doubts: I'm not convinced with the synchronously-replicated filesystem idea works well for heavy random/small-IO. GlusterFS isn't working for us yet, I'm not sure if there's another filesystem out there for this use case. The idea was to keep identical pairs and use DNS round-robin for email delivery and IMAP/POP3 access. And if one the servers went down for whatever reasons (planned/unplanned), we'd move the IP to the other server in the pair. In filesystems like Lustre, I get the advantage of a single namespace whereby I do not have to worry about manually migrating accounts around and updating MAILHOME paths and other metadata/data. Questions: What are the typical methods used to scale up/out with the traditional software (courier-imapd / dovecot)? Do traditional software that store on a locally mounted filesystem pose a roadblock to scale out with minimal "problems"? Does one have to re-write (parts of) these to work with an object-storage of some sort - such as OpenStack object storage?

  • Lisp: Determine if a list contains a predicate

    - by justkt
    As part of a homework assignment in Lisp, I am to use apply or funcall on any predicates I find. My question (uncovered in the coursework) is: how do I know when I've found a predicate in my list of arguments? I've done some basic google searching and come up with nothing so far. We're allowed to use Lisp references for the assignment - even a pointer to a good online resource (and perhaps a specific page within one) would be great!

  • c# Tuple - What is a practical use of Tuple [duplicate]

    - by Nate Pet
    This question already has an answer here: What and When to use Tuple? 5 answers I was looking at examples online of Tuple but I do not see any ideal use of it. Meaning, it seems like a place to store variables. Is there any practical use of Tuple. What I like to do is to pass in a value to the tuple and then have it return back 3 values which are all strings.

  • Resources for Windows Phone 7 development

    - by geocoin
    Windows Phone 7 has just been unveiled and right now there is no publicly available information to non-privileged developers/partners. MS are announcing all details of the development chain at the Mix10 conference. So until then this could be a good starting point/collection of online resources as they appear EDIT: I've added the speculation tag so we can also accumulate speculation. Please mark speculative posts as such. once firm details are announced we can confirm or delete them

  • SQL Server 2000, large transaction log, almost empty, performance issue?

    - by Mafu Josh
    For a company that I have been helping troubleshoot their database. In SQL Server 2000, database is about 120 gig. Something caused the transaction log to grow MUCH larger than normal to over 100 gig, some hung transaction that didn't commit or roll back for a few days. That has been resolved and it now stays around 1% full or less, due to its hourly transaction log backups. It IS my understanding that a GROWING transaction log file size can cause performance issues. But what I am a little paranoid about is the size. Although mainly empty, MIGHT it be having a negative effect on performance? But I haven't found any documentation that suggests this is true. I did find this link: http://www.bigresource.com/MS_SQL-Large-Transaction-Log-dramatically-Slows-down-processing-any-idea-why--2ahzP5wK.html but in this post I can't tell if their log was full or empty, and there is not any replies to the post in this link. So I am guessing it is not a problem, anyone know for sure?
