I'm in need of a dedicated server that their servers are located in UK, can anyone assist me of deciding which one would be the most reliable provider.
thanks
I'm considering running my laptop from a USB flash drive. The system would be one of the Ubuntu family.
What should I do to ensure that the USB flash drive lasts as long as possible?
What can I do to improve system performance?
I'm administrating a mail service for a small business. Their mail host's internet connection is an ADSL service with a permanent IP address.
Unfortunately, many misconfigured mail systems will happily deliver to this host, but, when the host attempts to send mail back (e.g. a bounce notice, or a normal response from someone), the declared…
There'a a belief that domestic chemicals (like washing powder many people use for washing the floor) and tobacco smoke can cause harm to computer equipment. Hard disks are believed to be especially vulnerable.
How real is the threat? Are there any researches/statistics that could help to assess the influence of domestic chemicals and…

Is it more reliable, faster, longer lasting to burn to CD/DVD a zip (or a few large zips) of files rather than the files as a folder?
Just thinking if 1000s of small files would not be as efficiently recorded compared with one or a few large zips.
Also, even after the burning program verifies the disc, I also use Beyond Compare…
I pooled together my photos from an old external hard drive, various Picasa Web caches, flickr, flash drives, and an old computer. They're all on my external hard drive, using extremely creative labeling, like allpictures pixix pix2 images familyphotos and so on (hey, I was 7 when I organized them last). My computer's hard drive…
Got a simple scenario with two web servers for redundancy and to scale.
But how do I make a two web-server setup fully redundant? I can think of two solutions;
two web servers, one load balancer spreading the load. one extra machine for the load balancer. but how will the load balancer be redundant?
two machines, each…
I'm deciding between go for a NON-SQL engine or a regular SQL one for a document managment system for small bussines.
I have experience with firebird/sql server and found a good track of reliability (specially with firebird).

Hi everyone,
I have thought a bit on how to make sure that a particular key is distributed to ALL memcached servers in a pool.
My current, untested solution is to make another instance of memcached, something like this:
$cluster['local'] = array('host' => '192.168.1.1', 'port' => '11211', 'weight' => 50);
foreach…
I receive a warning when I run some code through Visual Studio's Code Analysis utility which I'm not sure how to resolve. Perhaps someone here has come across a similar issue, resolved it, and is willing to share their insight.

I need to teach that a HTTP SOAP call may be received but the caller may not get the response due to a network failure (among other problems). (This problem made WS-ReliableMessaging be developed)
How would you guys show this problem to a web service developer so they can develop taking into account that duplicate messages…
Yahoo Pipes are a very intriguing choice for sort of a poor-man's server-free ETL solution, but would it be a good idea to build an application around one or many Pipes? I've really only used them for toy things here and there, with the only thing I've used longer than a week or two being one amalgamated and filtered RSS…
How much trust can I put in a standard computer running windows? To what certainty can I be sure it will run my code the way I wrote it? How can I be sure that if I declare something like "int j = 5;", j will alway be 5? Is there a way to measure trust in a standard x86 computer system? What kind of protections are…
Looking at the general trend of comments in my question about Building an Aircraft using Agile, the biggest problem other than cost appears to be safety.
Do people feel that it is not possible to build a safe system (or prove it is safe) using agile? Doesn’t all the iterative testing mitigate this? Is it likely that…
Hello,
We need to write software that would continuously (i.e. new data is sent as it becomes available) send very large files (several Tb) to several destinations simultaneously. Some destinations have a dedicated fiber connection to the source, while some do not.
Several questions arise:
We plan to use TCP…

I'm looking to get a fault-tolerant USB flash drive, which saves data to multiple independent locations, whether using RAID or some other means to back up data. Has a product like this ever been created, or are my only options to hack something together?
(By the way: I'm aware that RAID doesn't prevent data…
Looks like dynamic memory allocation without garbage collection is a way to disaster. Dangling pointers there, memory leaks here. Very easy to plant an error that is sometimes hard to find and that has severe consequences.

I've read as many search results I could find on this dreaded problem, unfortunatelly, each one seems to focus on a specific function call.
