  • Install Windows 8 without a Product Key

    - by User
    Windows 8 setup asks for the product key at the beginning of the setup without letting you install it. I got the Windows 8 ISO from MSDN but I didn't get enough keys to install it on all my 7 computers. Also, my MSDN subscription level doesn't allow me to get the VL product key to Windows 8 Enterprise. Is there any way I can install Windows 8 for a limited time period like we used to do for Windows 7 ?

  • Amazon S3 Iterating Through Multi-Page Results. (withMarker)

    - by Jitu
    Trying to iterate through AmazonS3 that has around 5000+ keys stored in the bucket, used sample code based on provided link on Amazon Developer Guide http://docs.amazonwebservices.com/AmazonS3/latest/dev/ListingObjectKeysUsingNetSDK.html Issue is iteration fails when NexMarker is passed which has length of more than 128 string characters, which seems unusal as withMarker accepts string as parameter and there is no documentation on limit to withMarker. request.Marker = response.NextMarker; Has anyone faced similar issue. Thanks in advance.

  • Learn to use both sides of the keyboard

    - by brewerja
    I'd like to force myself to use the correct (right side or left side) Shift, Ctrl, and Alt keys depending on what letter I'm typing. For instance I'd like to use the right Shift key when typing 'A' and the left Shift key when typing 'P'. I find myself using only the left side a lot and I'm looking for a way to set the mappings on my machine so that it only responds to correct pairings. I'm running Fedora, but any Linux distro support would be an acceptable answer.

  • How can I bring my IBM T60 out of sleep mode?

    - by Xavierjazz
    XP Pro - SP3. My IBM Thinkpad t60 goes into sleep, or hibernation? and I cannot wake it up, no matter what keys I press. This includes pressing Fn plus F4 ( with the half moon). The only method I've found is to do a hard reset, and this causes other problems. Is there another way? Thanks for any direction.

  • File permissions on a dedicated server [duplicate]

    - by Niet the Dark Absol
    This question already has an answer here: What permissions should my website files/folders have on a Linux webserver? 4 answers I have a dedicated server for my website. There are no other users, and no other websites on the same machine. Is there any risk in setting 777-permissions on my site's public_html folder, bearing in mind configuration files with passwords and access keys are stored outside that root?

  • Firefox: fast dictionary language switching

    - by Lo'oris
    I have two language dictionaries installed on Firefox 3.6, and I would like to be able to switch really fast between them, using the keyboard. At the moment the only way I know I can switch is right clicking in a text input field, go into Language, and then click the language. I would instead to be able to switch between those two just hitting two keys at most, if possible just one (something like F13). Searching for addons I've found tons of extensions somewhat related but that don't actually do what I want.

  • Managing servers over ssh with PermitRootLogin=no

    - by rickC
    If I can't ssh as root to each of my servers how can I make modifications in an efficient way? I am not allowed to setup ssh keys or open the sudoers file with NOPASSWD. I can't install puppet or spacewalk. Sometimes when I try to include a sudo command in a script I get the error "no tty present." Has anyone worked in an environment like this?

  • is there a way to tail a log from remote server without using any user credentials?

    - by suhprano
    I run a script tailing a log in a remote server, like so: ssh userx@someip tail -f /data/current.log|python2.7 monitorlog.py There are dependencies and service requirements that disallows me to run the script off the remote server. (DB, ACLs, and path to another service is uses) Is there a way I can tail and monitor a log without using the ssh userx@someip? I thought about generating RSA keys but I think you still need a user to ssh.

But it gets bad if you try to put breakpoint into the event. Why? I mean event is not run in the same thread that the windows hook is. That means that It shouldn't block HookCallback. It does however... I would really like to know why is this happening. My theory is that Visual Studio when breaking execution temporarily stops all threads and that means that HookCallback is blocked... Is there any book or valuable resource that would explain concepts behind all of this threading?

  • How should I implement simple caches with concurrency on Redis?

    - by solublefish
    Background I have a 2-tier web service - just my app server and an RDBMS. I want to move to a pool of identical app servers behind a load balancer. I currently cache a bunch of objects in-process. I hope to move them to a shared Redis. I have a dozen or so caches of simple, small-sized business objects. For example, I have a set of Foos. Each Foo has a unique FooId and an OwnerId. One "owner" may own multiple Foos. In a traditional RDBMS this is just a table with an index on the PK FooId and one on OwnerId. I'm caching this in one process simply: Dictionary<int,Foo> _cacheFooById; Dictionary<int,HashSet<int>> _indexFooIdsByOwnerId; Reads come straight from here, and writes go here and to the RDBMS. I usually have this invariant: "For a given group [say by OwnerId], the whole group is in cache or none of it is." So when I cache miss on a Foo, I pull that Foo and all the owner's other Foos from the RDBMS. Updates make sure to keep the index up to date and respect the invariant. When an owner calls GetMyFoos I never have to worry that some are cached and some aren't. What I did already The first/simplest answer seems to be to use plain ol' SET and GET with a composite key and json value: SET( "ServiceCache:Foo:" + theFoo.Id, JsonSerialize(theFoo)); I later decided I liked: HSET( "ServiceCache:Foo", theFoo.FooId, JsonSerialize(theFoo)); That lets me get all the values in one cache as HVALS. It also felt right - I'm literally moving hashtables to Redis, so perhaps my top-level items should be hashes. This works to first order. If my high-level code is like: UpdateCache(myFoo); AddToIndex(myFoo); That translates into: HSET ("ServiceCache:Foo", theFoo.FooId, JsonSerialize(theFoo)); var myFoos = JsonDeserialize( HGET ("ServiceCache:FooIndex", theFoo.OwnerId) ); myFoos.Add(theFoo.OwnerId); HSET ("ServiceCache:FooIndex", theFoo.OwnerId, JsonSerialize(myFoos)); However, this is broken in two ways. Two concurrent operations can read/modify/write at the same time. The latter "wins" the final HSET and the former's index update is lost. Another operation could read the index in between the first and second lines. It would miss a Foo that it should find. So how do I index properly? I think I could use a Redis set instead of a json-encoded value for the index. That would solve part of the problem since the "add-to-index-if-not-already-present" would be atomic. I also read about using MULTI as a "transaction" but it doesn't seem like it does what I want. Am I right that I can't really MULTI; HGET; {update}; HSET; EXEC since it doesn't even do the HGET before I issue the EXEC? I also read about using WATCH and MULTI for optimistic concurrency, then retrying on failure. But WATCH only works on top-level keys. So it's back to SET/GET instead of HSET/HGET. And now I need a new index-like-thing to support getting all the values in a given cache. If I understand it right, I can combine all these things to do the job. Something like: while(!succeeded) { WATCH( "ServiceCache:Foo:" + theFoo.FooId ); WATCH( "ServiceCache:FooIndexByOwner:" + theFoo.OwnerId ); WATCH( "ServiceCache:FooIndexAll" ); MULTI(); SET ("ServiceCache:Foo:" + theFoo.FooId, JsonSerialize(theFoo)); SADD ("ServiceCache:FooIndexByOwner:" + theFoo.OwnerId, theFoo.FooId); SADD ("ServiceCache:FooIndexAll", theFoo.FooId); EXEC(); //TODO somehow set succeeded properly } Finally I'd have to translate this pseudocode into real code depending how my client library uses WATCH/MULTI/EXEC; it looks like they need some sort of context to hook them together. All in all this seems like a lot of complexity for what has to be a very common case; I can't help but think there's a better, smarter, Redis-ish way to do things that I'm just not seeing. How do I lock properly? Even if I had no indexes, there's still a (probably rare) race condition. A: HGET - cache miss B: HGET - cache miss A: SELECT B: SELECT A: HSET C: HGET - cache hit C: UPDATE C: HSET B: HSET ** this is stale data that's clobbering C's update. Note that C could just be a really-fast A. Again I think WATCH, MULTI, retry would work, but... ick. I know in some places people use special Redis keys as locks for other objects. Is that a reasonable approach here? Should those be top-level keys like ServiceCache:FooLocks:{Id} or ServiceCache:Locks:Foo:{Id}? Or make a separate hash for them - ServiceCache:Locks with subkeys Foo:{Id}, or ServiceCache:Locks:Foo with subkeys {Id} ? How would I work around abandoned locks, say if a transaction (or a whole server) crashes while "holding" the lock?

  • Cannot Expand/Collapse tasks in Microsoft Project 2010

    - by Dean
    I opened an existing Microsoft Project file today and was unable to expand/collapse the subtasks use the cursor and the '+/-' signs beside the parent tasks. I am able to expand and collapse using the 'View-Outline' ribbon icon. However when I attempt to do this using the mouse on specific tasks, my cursor will not perform the task. My cursor is a 'white cross' when I need it to be an 'arrow'. I'm assuming this is something minor that I'm missing. Any assistance appreciated. Thanks

  • Server 2008 print server down / access denied

    - by johnnyb10
    I have two Server 2008 servers (both running as VMs in VMware). One is a Full Installation, and the other is a Server Core installation. I just installed Print Services on both of them. In Print Management on the Full server, I added the Server Core print server (so now two print servers are listed in Print Management). However, the icon for my Server Core print server has a red, down-pointing arrow (indicating that it is down, I suppose). And when I right-click it and click Add Printer, I get a message saying that access is denied. Can someone tell me how to bring up or check on the status of the Server Core print server. Obviously, I'm somewhat of a noob with this stuff. Thanks in advance...

  • Windows 7 locked out account

    - by Lukas
    I have a Win7 x64 computer. There was only one account (mine, created at installation, password protected, full administrative access with UAC enabled). To speed up the startup + login process I went to control userpasswords2 and unchecked that users need to enter password. By this operation my account has been changed to Guest type and an Administrator account has been created. This Administrator account has a small overlay icon with a downwards pointing arrow. My original password did not work; if I try leaving the password blank it says something like "Your account has been disabled. Contact your administrator." Contacting myself surprisingly did not help. As my account (which I am still able to access) is Guest, I have no rights to do anything. Is there a way to get my access back without reinstalling?

  • Picasa “sync to web” folders do not stay in sync

    - by jmbouffard
    I have multiple folders from the Picasa software that were moved to my Google+ profile using the "sync to web" feature. At some point I noticed that some of these folders were on Google+ and had the green upload arrow in Picasa, however the "sync to web" option was disabled. I tried to re-enable the "sync to web" option and it starts loading but after a few seconds the "sync to web" option is back to disabled. I get no error message, it just switches back to disable. Is there any way I could leave the option enabled? Out of around 80 something albums synced to Google+ only 3-4 are not able to have the "sync to web" option enabled. Thanks.
