Please, recommend network bandwidth limiter for windows which can be controlled from command line. No need for fancy options, only limiting of up and down traffic on a host required.
I recently reinstalled windows xp on my dell latitude d410 laptop, everything works fine as long as I don't shut down, when I do, I get a black screen with a list of choices, it gives me the option of trying to start windows normally or different safe modes, than a blue screen comes up and runs a check disk, it even ask me to pick a restore point the last time, which I did, I'm afraid to turn the computer off or restart it, what could be wrong?
I'm not sure if this is possible, or if I'll have to do it manually, but I have lots of cells in the following format:
=87.12+56.52-16.50+98.21-9.51
If possible, I'd like to break it up into columns, like so:
I have a data in excel in the format:
87.12 | 56.52 | -16.50 | 98.21 | -9.51
I've tried text to columns based on the '+' symbol, but it falls short when I then try to break it down by the '-' symbol, it moves into columns as appropriate, it removes the minus from the start of the figure
Any suggestions would be very welcome! Thank you
Can I configure my domain, example.com's name servers as:
ns1.dyndns.com
ns2.dyndns.com
ns1.opendns.com
ns2.opendns.com
That is, combining free dns services to create a redundant name server array? Note these name servers from different companies are not aware other companies' name servers also serve our domain.
In case one company, say, ns1(2).dyndns.com is down, will people experience interruption when visiting my example.com? If one name server is unreachable, the next name server will be tried, or?
Dragging a (Windows) scrollbar only works as long as the cursor is not too far away from the scrollbar itself. How can I 'fix' this bevaviour? Is there some kind of threshold in the registry?
Tip: to see this behavior: click on a scrollbar (dont' release the mouse button) and move up/down. This works, as long as you don't move too much to the left.
We have a SQL Server that has important databases for our clients, if the server goes down we want another server to be ready to be switched over (we would just change the IP). The question is, how can we automatically sync the primary SQL Server to the secondary one periodically through out the day? Or even in real time?
Thanks!
Memcache is the only important app running on the server
Server has 16 cores and 144G RAM
Memcache is given 135G
Memcache runs at 32 threads
Gigabit network, test shows at least 300Mbit/s availability on network port
600 connections
3000 requests per second
Say that memcache (memory) usage is at 50% - it's definitely not full
As we increase number of requests towards server, requests slow down (from 8ms to 100ms per request) but server load remains 0.00. We suspect this can be solved by adjusting configuration but we don't understand many of the configuration parameters (besides, maybe, the number of threads).
Any ideas?
I have a laptop with a LAMP setup. The HDD is slow, which causes my unit tests to run slowly.
I was wondering whether I could mount the web root the mysql database on some kind of ramdisk.
From what I have read of ramdisks, they are non-persistent.
Is there anyway to create a ramdisk that writes changes to an area of the hdd when shutting down and re-mounts the ramdisk on bootup?
I've just installed Ubuntu 9.10 Edition on my VMWare Fusion. host is Mac. I've installed successfully and able to use . Then, I've shut down and reopen again. Then, it's no longer response. like that
I've check Setting. it shows that running. I've waited for long time but no response yet.
Any idea better then reinstalling again ?
I'm setting up a jboss server for testing some java code that talks to http servers. That's pretty easy.
However one of the things I'm testing is interfacing with classic "old-school" HTTP-Auth protected pages, and for the life of me I can't figure out how to turn that on in jboss (and my google-fu seems to have let me down.)
So, how do I add a basic username and password to a single html (or jsp) file in jboss using http Basic Access Authentication?
Given two TFS security groups
Admins: Contains a set of Windows users
Friends: Contains a Windows Security Group (which is also used as a mailing list)
However, the people listed as admins are also part of the security group. It appears that when I lock down the Friends group to certain directories in TFS, the people in Admin also lose their privileges.
Is there any way for users to receive the maximum security allowed between multiple groups they are included in? Or have I perhaps setup my TFS security groups incorrectly?
I have set-up Postfix with Spamassassin on Ubuntu 12.04.5. Fundamental usage of Postfix is to (pipe) trigger a PHP file. Till here I've arrived successfully.
Now, to avoid unneccessary load on the server, and also to avoid unwanted mails triggering my PHP script, I want to configure Postfix to allow mails only from [email protected] and reject everything else.
How to achieve this absolute lock-down on mail server unless mail comes from [email protected]?
I have multiple computers, some have a 10/100 ethernet adapter while others have a 10/100/1000 ones. If I connect them together with the Cisco sg100-08 switch, do I keep the 1Gbit speed where possible (between two devices at 1Gbit speed) or the whole lan slows down to 100mbit? I checked Cisco website but I couldn't find this kind of information, nor I was able to register to the Cisco support to ask this question (the registration form does not work)
I broke my laptop and had to buy a new one with a new keyboard that I am struggling to get familiar with, especially with the keys like home, page-up, page-down and end, which aren't standardized at all.
I found myself doing this for like the 5th time in the last several years, and I think it is really annoying.
Is there an app that can reliably map one key to another? By reliably I mean that key mapping works with Shift, Alt, and other modifiers.

I've audited a SQLS2008 server with Profiler for one day.. the overhead didn't seem to trouble this new client my company has. They are using a legacy VB6 application as a front-end. They're experiencing timeouts once SQLS RAM usage is high.
The server is currently running x64 sqls2008 on a VM with nearly 9 GB of RAM. SQL Server's 'max server memory option' is currently set to 6GB.
I've put the results of the trace in a table and queried them using this query.
SELECT TextData, ApplicationName, Reads
FROM [TraceWednesday]
WHERE textdata is not null and EventClass = 12
GROUP BY TextData, ApplicationName, Reads
ORDER BY Reads DESC
As I expected, some values are very high.
Top Reads, in pages.
2504188
1965910
1445636
1252433
1239108
1210153
1088580
1072725
Am I correct in thinking that the top one (2504188 pages) is 20033504 KB, which then is roughly ~20'000 MB, 20GB? These queries are often executed and can take quite some time to run. Eventually RAM is used up because of the cache fattening, and timeouts occur once SQL cannot 'splash' pages in the buffer pool as much. Costs go up. Am I correct in my understanding?
I've read that I should tune the associated T-SQL and create appropriate indices. Obviously cutting down the I/O would make SQL Server use less RAM. OR, maybe it might just slow down the process of chewing up the whole RAM. If a lot less pages are read, maybe it'll all run much better even when usage is high? (less time swapping, etc.)
Currently, our only option is to restart SQL once a week when RAM usage is high, suddenly the timeouts disappear. SQL breathes again.
I'm sure lots of DBAs have been in this situation.. I'm asking before I start digging out all of the bad T-SQL and put indices here and there, is there is something else I can do? Any advice except from what I know (not much yet..)
Much appreciated.

I'm working on a web app that will have a large-ish chunk of users in China. The bad news is that most of them are university students, and access has been blocked.
Setting up a proxy server inside China seems like the best (potential?) solution, but it's the first time I'll have done anything along those lines. Are there any pitfalls or issues that I should be aware of before I start down this path?
I'll have to deploy virtual machines on demo laptops, which will use Vmware player, but I've got some security concerns, as some data stored in the virtual machines are a bit sensitive.
Is there a way to prevent the copy of these virtual machines ? Are the virtual hard drives encrypted, and if not is there a way to encrypt them ? In short, is there a way to lock down everything so that nobody could copy and or use these VMs in another computer ?
I want to get rid of them all.
For a li'l explanation on what field. Go into the search of file, move into the field with that name and without writing anything else, press the down arrow (you have to had used it before).
I have 8 SQL Server installations (on 8 separate servers).
I want a way in which I can estimate future disk space requirements. Can anyone list down the parameters which can be helpful in making such reports?
I got this old box with windows xp home. It works perfectly, except the occasional blue-screen when shutting down the machine.
How long should I expect this, or any, machine to work, when will the hardware start failing and should I worry about silly things like upgrading the os?
What is the TTL on HW you purchase today?
I know I can force it to boot into 64-bit kernel by holding down the 6 and 4 keys during the boot process. I also know that some extensions still don't run in 64-bit mode.
So the question is what might I gain by running in 64-bit mode?
If it matters, I have the brand new 2010 15" MBP with the faster processer and 8GB of RAM.
i'm having a very strange problem:
i'm running win7 64bit on my laptop - i hooked an external HD via usb3.
when saving something in certain applications (eg. notepad), the file dialog pops up then the whole system is freezing .. like applications won't react anymore, also taskmanager, so i can't terminate anything. i think it's the external HD which is powering down after a while.
anyone who knows this problem and can tell me how to fix it?
thanks
Had a power outage last night, still cleaning up from that. I have a file server that doesn't know it's part of the domain (getting the error: windows cannot connect to the domain either because the domain controller is down). I read that "resetting" the machine account the bring it back into the domain will do the trick.
Since this is the file server for the entire office, I would like to be sure that I won't bork the umpteen number of shares on this server.
Thanks!
I know that this is not exactly a programming question, but this is pretty geeky stuff so please don't vote me down.
When ever I plug in my iPhone into my work computer Word 2007 decides it wants to start up.
How do I make it stop? Is it a registry deal, or is there an windows interface that I'm unaware of. I'm on Win XP SP3 by the way.
Thanks
So, I have a Dell R710 with PERC 6/i Integrated and 6 450Gb Seagate 15k SAS disks in RAID10, I have 30 Xen vps working on it. Now I need to deploy second server with same hardware for same tasks and I want to figure out maybe it's a good idea to use RAID5 instead of RAID10 because we have a lot of "free" memory on first server and not so much "free space". How do I find out disks performance on first server and find out could I move it to RAID5 without slowing down of whole system?
