Most people here know what NTP is (no need to point to man..), and it's safe to assume BT's network devices all use it. The problem is, MANY destinations don't run it, or run it improperly (I can't count the amount of times I've seen 'ntpdate' in a cronjob instead of running ntpd). And unless they're in perfect sync with BT, then cross referencing will still be difficult (assuming the destination is getting a sizable amount of diverse traffic from BT customers behind the same NAT'd address).
Really? What is the resolution? Have you tried replacing the wifi card? You can't unless its blessed by Lenovo, the BIOS prevents the machine from booting artificially if its pci id is not in a whitelist. I will never buy Lenovo again because of this very reason.
Given I upgraded the build to have the exact card I wanted, I can't really see that being a problem for me. They have a couple options IIRC, do you just not like them or something?
I recently purchased an x230. It's light as hell, has an IPS display, quad core, 16GB RAM, 160GB SSD, and displayport. Best of all, ALL HW was detected perfectly by fedora 18.
but it's a hell of a lot cheaper, faster and easier than running such a cluster
This is at best only true on a small/medium scale, but ultimately it really depends on your use case and how on top of your AWS bill you are. My contention is that once you get to the point that you're running thousands of large EC2 instances, you'd actually find it cheaper to deploy and manage servers in your own DC (or a colo).
I'm sure the folks at Netflix will disagree with me, but considering the hundreds of folks they have dedicated to tooling and optimizing their AWS deployment, I'd say they're a special case (plus they likely get big discounts given the amount of cheerleading they do for AWS).
Austin != the rest of Texas.. Their motto is "keep Austin weird" and it's a mix between hipsters, republicans and tech savvy professionals. A very dramatically different place than any other Texas city.

5. 'it worked in dev'. your Dev DB had tables with 10 records. Prod has 20 terabytes of data. We have told you that prod is much bigger. So you need to atleast check to see if its using an index. This is NOT difficult and I show them how, but they don't care.
Isn't this faulty design? It's not a developers fault that the dev environment wasn't built properly...it should be as close to prod as possible. How is performance testing even remotely possible when the discrepancy between dev and prod is so massive?
are you being intentionally obtuse? so you have a single physical server, and you throw xen on it. how can you enable a developer to easily launch several guests that make up a db/app stack on which he is developing? now extrapolate to 1000 servers. tools built to make this easy and to manage them as one unit can define a cloud computing environment. openstack is one such suite of tools, eucalyptus is another. AWS is an example of a commercial provider of an environment like this, fully API'd for ease of use. before the "cloud" movement, none of this was even remotely easy to do...so the need is there.
i'm sorry, but i'm not interested in quoting the definition for you, feel free to read up:
And honestly, why should they (ARIN) have the right? I'm sure HP considered their second/8 when they bought Digital (at least I think that's who they got it from)...why should they now be forced to give them away for free?
Yep, I love my Sprint/Clear Wimax service...I get ~12Mb down / ~1Mb up pretty much everywhere I get a signal! They even already have solutions that will fall back to 3G when 4g isn't available. The coverage is definitely sparse right now (at least in my area I have to be pretty close to a major road and near the city), but they're clearly far ahead of this Verizon/LTE rollout.
I'm not saying we should nerf the engines, but just limit the max speed of the vehicle but keep all the HP/torque so you can go from 0-60 in 2seconds, but you top out at 85mph.
ever heard of taking your car to the track? some of us (legally) race our street cars and would prefer a higher top speed than 85mph, thanks.
Perhaps the GP was referring to T-Mobile's "3G" data coverage. It IS very sparse (in the US), and even if you are in a 3G area it's still slightly slower than Sprint's data network (and possibly Verizon's, too, but I've only tested against Sprint).
My MDA (HTC Wizard) has been dropped (HARD once or twice) several times and the worst that happened was one of the tabs for the battery cover snapped off.
Not to mention the awesome support for messing with it.
NTP is your friend. man ntpd.

So not all Lenovo laptops are getting worse..
GM is bringing a lot of tech jobs back to the US, but not just in Detroit:

Great post, but I do disagree with this:

I haven't priced tapes lately
That's too bad. If you did, you'd know why many of us still use tape...especially in times like this where every penny matters.
Nothing is stopping the Chinese from building their own search engine.
ummm, Baidu?

Verisign. Because of the ridiculous cost of THEIR certificates, and that browsers don't seem to properly recognize any certs but ones from Verisign.
Take a look at Entrust. I've switched all my certs to them as they seem to be supported by just as many browsers as Verisign -- and are much cheaper.

that's a lot of work to do what 'disown' does

I LOVE my HTC, but I suppose YMMV.
go ahead and add freescale to the list as well
although the article doesn't mention it, the percentage seems to be about 10%, too (of a ~24,000 employee company)
