Digital already surpasses film for light sensitivity, I can shoot from ISO-50 to ISO-3200 with my sub $500 DSLR. It will be quite grainy at ISO-3200 but so will film. As the examples at this site show modern digitals also have a greater dynamic range then typical films. Also the existence of HDR imaging shows that in practice you can achieve significantly higher dynamic range using digital techniques than you could with film.
Not only that but better sensors are fairly worthless, we are already at the point where it's the LENS that's the limiting factor for picture quality. The only way this makes a difference is if it costs less to make the same size sensor which is unlikely since it's competing with bulk CMOS technology.
Hahaha, 6 years after my friend graduated at the top of his class with a CS degree (and 9 after I entered the workforce) I still make more than him. Network admins make more than all but the very top designers because while you make products we make large numbers of people efficient which is more valuable to most businesses.
I'm the senior network administrator for an S&P 500 company and I have some college but no degree. I do have a ton of industry certifications, but I only got those for employers who asked for AND payed for them. Of course before I got my first "real" IT job I had already owned my own PC company for 5 years and volunteered for a number of different schools and charitable organizations so it wasn't like I went in with zero experience to show on the resume. I also started near the bottom as a deskside support guy. I think the only way to get in today without any formal education would definitely be to work a helpdesk position. Personally I would look for a midsized company because if you show good initiative, hard work, and some smarts it's a lot more likely you will move up from within. That's what happened to my junior admin, he had been stuck at the helpdesk level at a number of very large companies but within 2 years of starting with my company he was advanced because he showed all the traits needed to be a good sysadmin.
Perhaps, but the G92 in my graphics card already has 96 cores and they are significantly more powerful for graphics than a general purpose CPU core. Do I need to mention that the G92 launched 2 years ago? The GTX280 has 240 stream processors so they are roughly doubling ever 18 months as expected.
Yes, but running something like a 9600GSO will require less power than pushing 8 cores on the Core i7! The TDP on the Core i7 is 130W, my 9600GSO has a max power draw of 65W. Not only that but you can get PLAYABLE framerates, like 30fps@1080P.
Yes, there is a perfectly sane reason to use FAT32 on a modern computer, the lack of an ACL node to be updated means that compiles that are I/O limited can see a HUGE speedup by being targeted at a FAT32 partition. Under Windows 2000 I was blown away by the 250% compile speed performance one developer got by using a relatively small FAT32 partition for his compiles.
The other reason is of course to format any type of media that needs to be used in another computer or a non-PC electronic device.
Of course, while I'm at it, I have this other idea -- unify disk caches. It should be possible for me to allocate my entire available free space as a shared cache, between my package manager, browser, everything -- then, provide a common mechanism for reclaiming that space when something wants disk space.
Bad idea, a huge cache is actually less efficient than just grabbing the data from the source in many instances. Imagine you have 10M items in your disk cache, trying to find a 1x1 pix graphic in the index of 10M items is going to take MUCH longer than just downloading that file in the HTTP 1.1 stream.
Personally I buy the game and install the no-cd executable. I say screw securom since it helps me not one bit but has the potential to mess up my system severely. It's funny that a bunch of hobbyists deliver a better user experience then the game publishing industry!
It's going to be REALLY hard to justify Spotlight (or anything from Quest) for a 10 server environment! I love their stuff but it's very pricey, especially for small installs.
If your friends time is worth anything then I highly suggest using WhatsUp Gold from Ipswitch. Dead simple to setup yet very customizable. Tons of canned reports and graphs. We use Firefox Showcase and ReloadEvery addons to display a 3x3 matrix of graphs to monitor overall system health.
Is there no middle ground? Here in the US we were paying old rates for 4 bonded T1's (1.5Mbps symmetrical connections similar to an EU E1 only slower) and for the same price per month our ISP moved us to a fiber based DS1 (45Mbit symmetrical) with base bandwidth of 10Mbps averaged over the month and tiered pricing up to the full circuit. They did this for several reason, one they got to free up 4 ports on the local router for other customers and 2 they have the possibility of higher revenue in the future (renewal rates on the T1's would have gone down significantly).
That was brought up when the flaw was released and the reason it doesn't work is that the glue records were a workaround for another DNS flaw (which I can't remember at the moment).
That RFC makes my head hurt. After a few readings I can usually grok most RFC's, but that one is particularly dense with acronyms and references to other DNSSEC concepts not included in the RFC. Also I don't see any provision for multiple signers, my ideal system has each of the ROOT servers having their own key and each zone being signed with each of the keys from the ROOTS they trust. That way if some government or corporation does something you disagree with you can choose to revoke their key as either a signor or a receiver.
Better Gmail (force HTTPS for all transactions)
Download Statusbar (puts the downloads in a ~20px bar at the bottom of the screen)
Firefox Showcase (shows a tiled view of open tabs including refreshing pages, used for system monitors)
Forecastbar Enhanced (Customizable weather bar)
Greasemonkey (nuff said, wouldn't be an issue if Greasekit was available for Windows)
Nuke Anything (nice for one off removal of DOM objects where I don't expect to need to kill something enough to write a greasemonkey script)
Reload Every (reloads tabs on an individual timed basis)
User Agent Switcher (nice to look like IE or googlebot)
If there are replacements for all those I will consider switching.
We don't HAVE local drives, we use HP 1U servers with HBA's and boot from SAN. It's much cheaper to use a pizza box with SAN storage than to build a big beefy local storage server, especially when we built ours 2.5 years ago. SFF drives have increased local storage spindle counts pretty significantly though so the outlook might be different today. It's also significantly easier to manage growth on the SAN, we unfortunately lost the war on quota's so planning for growth is basically analyzing trends and growing the LUN's when needed.
Nope, we generally run with a couple GB free, email is just a high I/O application. I've always tried to build my email servers like a DB server (separate raid 10's for email and logs) because modern email servers ARE database servers.
Well I just checked and a hot disk in my SAN has done a bit over 15M 128K writes in the last 3 weeks so about 1.92TB in 21 days or close to 100GB per day. I have replaced 3 drives out of 150 in the last 2.5 years (well 5 total but 2 were precautionary from the SAN vendor when trying to troubleshoot another issue). This is a pretty lightly utilized SAN, we need it more for capacity then pure I/O. I can see a busy installation doing 10x what we do without even pushing the same hardware to its limit.
Depends on what I need, but it does allow for an interesting mix. Throw 300GB 10K disks for bulk storage fronted by a couple GB of write cache and these drives for things like transaction logs and you are looking at a real winning combination. Might bring down price too since you will need so many fewer spindles for the storage and should definitely bring down power consumption. The hardest part would be new installations where you don't know what you biggest users will be and what your mix will be. One of our biggest surprises is that our Lotus Notes servers are almost as rough on the SAN as the DB servers, huge numbers of IOPS and almost as much storage.
Basically allowing the drive to have a queue of requests and responses outstanding. Your host will often be bursty and want to send a bunch of commands at once which even an SSD won't be able to service, but it can service them much faster than the host can issue, receive, issue etc. Think of it as turning on Async I/O at the hardware level.
Hmm, at 4K DB IOPS for $719 that compares very favorably with my SAN 250K DB IOPS for ~$250K. Now for the same 7.5TB of RAID10 storage it would cost $337,050 without controllers so the SAN still wins out, but things are getting very interesting. I would expect to see drives like this make it into a high performance storage tier from SAN vendors very soon if they don't already have such an option in their lineup.
Actually there is a row access time which can be quite high, as high as.5ms for MLC which compares with 2.5ms for 15k rpm drives. Add to that the relativly low IOPS for MLC (less than 100 according to this review using the database server IOMeter profile which is 70/30 read write if I remember correctly) and for a server load they lose bigtime to drives considering they get worse performance, have significantly lower MTBF, and have way less GB/$. SLC is a bit harder to quantify as the best units have MUCH higher IOPS per unit than disk so you have to figure out how much capacity you need and how reliable you want it to be as well as how much power budget you have.

More like duped, they bought the backup link through a reseller a long time ago and never activated it till Sat 11/15.

That's at a measly 100GB of writes per day, in a DB server it could easily see 10-100x that so between 7.5 years and 8 months.
