The guy at the local PC hardware store told me it's better to use a small hand-held leaf blower to blow dust out of your PC case than a hand-held vacuum cleaner. Why is this? I understand that fans might be damaged if they "spin too fast", but surely this is a problem with both vacuuming and blow...
The teacher here that does "Web Programming" classes just asked us to "install" Wordpress on his notebook. He wanted to be able to share things with his class and he wanted to be able to take it home with him. O_o
I did web design in college, we had two teacher the opposite ends of the scale. One was someone who did websites professionally, ran his own site, knew evrything inside and out, and the other had trouble "with the internets"
I'm soon going to change my infrastructure when I buy a new server. I'm going to replace my D-Link DIR-655 router with an pFsense router (and probably use the 655 as an AP) using my old server hardware (Intel Atom 330, 1GB ram, Intel Pro Server MT Dual Gigabit nic).
My new server will be SandyBr...
@DanBig He's been aloof for a while now... I think he's more than slightly disenchanted with our propensity to attract "gives me teh codez" and "how to use mod_rewrite" questions too.
@ChrisS, just seeing the way he interacted in chat, i would usually leave, as he was prone to just disagree with everything, and it was annoying to watch
At my previous job, all C-Levels had local admin access, and that was given whether IT liked it or not. It was frustrating to watch these people make a mess of their systems, demand it to be fixed, only to do it again. When they would get a new machine, we would, by default, make them only a user, they would complain by CoB that day that they couldn't install something on their own.
My predecessor used to put Everyone in the Local Admins group on computers... Can't imagine why they were paranoid about security... litterally anyone could get on the network and remote admin the computers, login, browse the file system... It was an impressive Charlie Foxtrot.
You don't really protect yourself from DDOS from your end. You identify traffic and coordinate with your ISP to block it before it gets in your link. If you have to block it in your side, you already lost the battle because your tubes are already clogged (the packets must reach your FW before bei...
And Chopper held aloft his magic server and said..."By the power of Grayskull!" Then he transforms into He-Admin, the most powerful BOFH in the Universe...
@ChrisS I would have to measure it to be sure, but probably, and since it's in a different building I can't run up and verify. I've noticed problems with rails not compressing down enough.
@ScottPack Well that certainly is annoying. One of our racks here was setup at 29" originally... That was a PITA to change with it half full of servers. They had a tape backup unit with perfectly good rails too, but the rails weren't mounted because they required the ~32" spacing... I can't tell you how annoyed I get with people take halfassed shortcuts; then I get to cleanup the mess years later.
@ChrisS In their defense, this was largely designed as a forklift with a Cellera in the bottom and 3 RSA rebranded Dell 2950s. The Dell rails have two rear mounting points so it will fit in either a standard rack or one of these. It just happened that with 20-odd U left empty it became the rack for my dept.
Hey everybody... it's me, Dan. I'm the guy who made this claim, and I'm here to talk more about it. Here's the long, drawn-out version of what happened.
I was managing a NOC for a fixed-data wireless company in Florida at the time- fuzion (gofuzion.com - I could write a book about that place). I...
I felt like they wanted to be drinking buddies after that.
@BartSilverstrim To be fair...no. When someone becomes one of my "users" they're usually told to pay attention. Now, they may ignore it, but I at least know they're rather required to read/listened/whatever.
@BartSilverstrim Too localized to his situation... I don't know anyone who really needs to know what their ads look like from different countries, but don't have the technical know-how to do it themselves.
Subnet mask is usually something like 255.255.255.0. And until now, its the field I usually ignore.
I am trying to read the wikipedia entry, but its pretty loaded with jargon.
Can anyone explain in simple terms what a subnet mask is for and how it works?
I have a print server that seems to be unable to communicate to a specific MAC address and every other devices (Windows XP machines on the same local network) can. Has anyone seen an issue like this before?
I'm going to try updating network drivers first yet feel free to provide some insight.

I'm currently trying to buy a whole bunch of Windows 7 licenses to upgrade XP and Vista Home Premium to Windows 7 Professional.
It seems like a good time to start on an Open License agreement. Every time I talk to a vendor, or go through Microsoft's Licensing website, I see references to Softwa...
SA is boils down to a subscription service, you pay $X/yr and you're licensed for the latests version of whatever you're looking for. For instance, if you got SA for Vista Enterprise 10-licenses, and keep it up, you got Win7 Ent licenses when it became available.
@TomOConnor It's basically a lease vs. buy decision. Do you want to pay an even amount every year, knowing it'll probably add up to slightly more than one off purchases every 3 to 5 years.
Say you have $5000, and need a new server (server happens to cost $5000). You can buy it now and have $0 leftover; OR lease it for $2,000/yr for 3 years.
If you do the lease you'll have $3000 for the first year; you might be able to invest that in the business/bank/stock market/etc, and make additional money.
Lets say you can invest it in your business and make $1,000/yr. Over the 3 years, you'll make $3,000; the least cost you an extra $1000, but you're still ahead $2,000 in the end.
Let's say the terms of the lease allow you to buy the equipment after 3 years for $1, not an uncommon deal (except in auto leases, which is what everyone is most familiar with).
My number were obviously picked for convenience, and I really doubt the 33% return is realistic; but the general idea holds and works out quite often in larger businesses, or especially in rapidly growing businesses.
@TomOConnor Yeah, auto and real estate leases almost never allow you to buy the goods at a discount after the lease; they're usually money pits, as you suggest. Most business equipment tends to be a different story, with $1 buyout options being quite frequent (I know HP offers this as an option to all their leases [does cost extra for the option....] and I had a buddy who was a lease officer for a firm that did this stuff all the time).
Hello,
I have probably quite easy question:
How to explain to a client that he must generate his SSL certificate using CSR generated on hosting IIS server?

after I tried to install the experimental Gnome 3 I ended with a GTK conflict and Nautilus refuses to work, so every time I need to open a file I have first to open the app and then use the open dialog on it to search the file :P
Just got my new shiny shelf of 15k SAS drives mounted. :) Not connected to the SAN yet, that will probably be tomorrow evening, as I'll need to do a controller failover for the install.
Basically I want to create a situation where files served from my /cdn directory to use my cdn host rather than the local host.
How can I do this with apache rewrite?
@ScottPack I know. Ticked me off. The rails of the SATA shelf (which is in the middle currently) descends down about .25" into the U below where it's supposed to be.
So... I have two rows of racks that will need to have a couple 1 foot spaces in between the racks due to structural engineering issues. Any good tips on what to fill that space in with to maintain airflow containment?
Talk to your local vending company. I've seen lots of vending machines that have several inch wide bumpers, for lack of a better term, that separate the machines. As near as I can tell they're effectively just foam wrapped in some kind of leatherette like material.
I heard that only 10k users are allowed to review (and approve) edits done by the little people. Why set it so high, especially if you allow a 2k uses to edit without apporval?
@ChrisS Well, It sorta just makes sense, if I can edit without approval myself, I think its also true that I should be able to tell if a lower rep users edit is good.
I know we've had this discussion before... I guess it's semantics, but I think you're probably more "efficient" than "lazy". I think of lazy as doing less than what's required and hoping to get away with it. Efficient is putting in minimal effort while accomplishing the goals.
@Zypher I know of the existence of the store through channels... If I were to order a SF tee, could I get it before PICC do you think, or have you not have them made?
@Zoredache I initially thought my shirt would never come. In fact, when I received it, so much time had elapsed that I had completely forgotten I even gave them my info for one.
Hey guys, I'm doing a switch from Exchange 2010 to Google Apps, and I wanted to know if there is a rule of thumb for bandwidth requirements. This is with 100-200 users.
if you want a serious assessment, email is probably the least of your bandwidth utilization -- look at web traffic, streaming, etc. and see how that's doing first. If you're using >80% of your bandwidth an upgrade is probably a good idea. If you're north of 90% it's mandatory (unless you want to start aggressive traffic shaping).
@user65712 Well, that's a tough call: I used to suggest biting them off as a warning to users, but with the prevalence of STDs now (and the chance for contracting terminal stupidity from contact with user-blood) I suggest using cigar cutters and observing barrier precautions...
if you're already hitting the ceiling occasionally you definitely want to upgrade first. You may also want to consider reserving bandwidth but that's not really easy with Google services because they're coming from/going to all sorts of networks....
