The use case here is moving uncompressed video within a studio environment. In here, you have full control over the hardware and Internet does not come into play. I'd think that in such cases they have no problems in going to jumbo frames.
We rely on our server uptime because of someone else's electricity (we should just generate our own)
I haven't yet seen a datacenter (or even a server closet) that doesn't have at least a small UPS (to allow graceful shutdowns). For mission-critical environments, you actually *do* have back-up generators and the like (Think hospitals). Following that analogy, a hybrid option is actually one that might be worth pursuing, putting services into a cluster and having part of the cluster hosted on-premise.
It all comes down to cost-benefit-analysis. The problem with doing that in regards to cloud computing is that some of the variables are not only vague, but they might be completely unavailable. There is not really enough information to make rational decisions on such aspects as privacy, confidentiality, reliability, and so on. Some of these might get better defined over time (such as reliability), but with confidentiality it all comes down to trusting your cloud provider.
1) Because the bundled heads only contained like 6 grams of ink, while the replacements have two or three times that 2) When I do print, I usually print larger documents, so dozens of pages get printed at once, and then there's again a long pause
Has solved it already a few years ago with Epson Claria inks. They are still costly (based on the cartridge-pricing-model), but the whole point of that product is that it doesn't block the heads if you don't print anything for a while.
I have an Epson PX720WD myself (got it cheap out of a dealer going of of business), and use it *very* rarely. There may be several months between sheets, and nearly a year between color printings. I've replaced the cartridges once. And never gotten a blocked printing head.
Their UI is based on Flash (and Java), for remote console, status data, and so on. If I point a browser to a CIMC server, the first thing I see is "Install flash player" if it's not already installed. Even if Cisco would release an upgrade *today*, how often are people interested in rebooting their servers for firmware upgrades as long as it's running ok?
Anecdotal evidence, I know, but I've heard from a friends who has been living in mainland China for a few years now. This topic on rhino horns has apparently come up a few times.
This is one of those cases where having a public awareness campaign in China might actually help.
The issue: Lots of chinese believe that getting a rhino horn doesn't involve killing the rhino. They believe you can just pick them up from the ground - that they work like elk/deer/moose horns that drops away from the head every now and then. Once the locals have learned the truth, they have usually been apalled.
The mystical/medicinal crap aside, the fact that folks don't *know* that rhino horn has to come from a poached rhino is a big factor.
Most certs do indeed prove only that you can answer multiple choice questions. However, there are certs that truly matter, but not from skills perspective (although that helps).
CCIE is a good example, since it requires the lab part (I know some folks actually try to do the lab part by rota, with several attempts, but it's still rare). Some others might be the architect-level certs from Microsoft or Oracle. CISSP is a bit in the gray area, it's not a vendor-specific cert, but many customers actually appreciate it.
Anyway, while the highest certs may "prove" something about your skills, the biggest benefit is actually in something completely different. If working for a vendor partner (Cisco, Juniper, Microsoft, whatever), they typically give you status levels based on the number of cert-holders in the company. So basically, if you have a good enough cert, you can waltz in and say "even if I come here to watch porn every day, you can still pay me and save money". What it really means that even if you are a slob who has just gotten the cert by rota, the company can afford to pay you due to the vendor discounts. If you actually know what you are doing, even better.
I mentioned the CISSP, it's an example of a cert where having you on the payroll does not mean discounts from vendors - but it might give the company a possibility to enter higher-paying projects. Many RFQs usually hand out points based on what certs the people involved actually have.
Well, this example is just a simple load balancing with outbound NAT and nothing as fancy as the stuff you cited which aims for e.g. multipathing single sessions like MPTCP does.
Effort has been underway for quite some time - by folks such as Vint Cerf, no less - to facilitate Internet over long delays. Surprisingly, there has been terrestrial (or aquatic) applications in the research as well, for example solar-powered sensor networks that can only transmit during daylight hours.
There's a nice overview architecture draft from 2003, especially interesting bits are in the routing section (12.3-12.4), see https://tools.ietf.org/html/dr... - the eventually published RFC https://tools.ietf.org/html/rf... has nowhere such interesting figures about routing between Earth and Mars:)
Anyway, the underlying arch is relying on putting a "bundle layer" between applications and transport, a layer 5 if you will - and the bundling will attempt to hide the long latencies. Naturally, for interactive applications this won't work, but for everything else why not...There are some implementations at http://www.dtnrg.org/wiki/Code.
Trust me, they are still used in M2M connections in places that only have PSTN and where cellular is flaky. I had to set up US Robotics modem and hook it up to a Cisco router's AUX port only last week so customer could do interoperability tests with their newly ordered modems. Yes, it's mid-2010's.
Already implemented with routing protocols. Take a look at e.g. https://tools.ietf.org/html/rf.... Of course, not every small shop has expertise to set up BGP peering with their ISP, nor do the ISPs provide the service..
Since no one has mentioned this yet - I'm not sure if this applies in the U.S., but at least in Finland you can deduct profession-related (not necessarily work-related!) expenses from your income taxes.
This typically includes stuff like literature, computer equipment (if used for said income), and yes, even travel expenses. Of course the expenses have to be related to your profession - my education and entire professional history is from CS, so I cannot put e.g. gardening tools in there, but a trip to a conference related to your field can be easily put under training expenses.
I have this problem as well with not just online courses but several video "tutorials". It's been numerous times recently that I've googled for for "how do I...." and the top results have been videos. I typically have some idea on how to do what I'm looking for, and I just need to verify some details. So now, Instead of quickly skimming a text (or even a slideset) to find the exact bits I'm looking for, I have to try to fast-forward a video to a point where it gets interesting.
This is especially problematic when you are just looking at a talking head droning on, or just a video of someone doing stuff with an application. One exception has been when I wanted to cut down a tree in my back yard. There was no danger to surroundings since the house wasn't anywhere close by, so I figured I could just cut it down myself. In this case, the videos on how to use a chainsaw helped a lot, since it showed actually *stuff happening*, not just a talking head.
If these video lectures would even have transcripts, that would increase their usability tremendously. Considering that youtube is now offering closed captions created with voice recognition, such transcripts could perhaps be generated automatically soon...
In a way, I hope for a video game crash similar to 1983. This may be the only way we might see actual creative gaming again, since the cool games are not going to come from the big names.
Are you nuts? The world of games is better and more interesting than it has been in *years*. All in one: Kickstarter. From about a period of 2003 to 2010, the only interesting games for me besides WoW were things like Civilization series. (Oh, and Half-Life 2).
Now we have a *ton* of "indie"/kickstarter projects. Some are not yet ready, but just off the top of my head (yes, I've put money in all of them): Star Citizen, Shadowrun (and the DLC Dragonfall), Torment/Numenera, Shroud of Avatar, Elite Dangerous. And even the "AAA" stuff is better than in ages - Far Cry 3, Skyrim, Portal, and so on.
Gaming seemed dead to me for almost a decade, the 2000-2010 were really dark ages, and I was thinking that maybe I've just "grown out" of games.Turned out that the problem was the games instead.
Not modem reset. The filesystem on Spirit had bunch of temp files and other stuff from the Earth-Mars flight, and apparently it just ran out of inodes. So basically they had to remote into whatever constitutes a bootloader with 20 mins of latency and remove some of the no-longer-needed files.
Battlecruiser 3000AD being one example. The first studio that released it ran into financial trouble and rushed it out the door before it was ready. Patches were eventually released and development continues still, at least the last time I looked It's had a somewhat cult following, but never attained the status it probably could have.
Are you kidding? Derek Smart's personal little ultimate vaporware project, where we couldn't see anything like that until Duke Nukem Forever? It was not "rushed", considering it was like what, 10 years in the making?
BC3000AD was one of those things were the dev(singular) attempted to bite down more that he could chew.
Pushing Ice by Alastair Reynolds has this tech. The author points out in the afterword that this actually one of the few things that might be reality even today - apparently it's now starting to appear more widely...
Anyway, sounds good, I wonder how far the preservation could continue. The old cryogenics scenarios start to come into mind...
I don't see the problem with the tech itself. If you have a "BYOD's allowed" policy, that also usually states that "if you put your own device in, here are the rules". Rules may state installing the network owner's root CA and allowing for traffic to be inspected.
In most cases, this is intended to be benevolent - it's kind of hard to run threat detection algorithms on an encrypted connection. In business environments, DLP and similar can of course be used too.
Now, in here I think the key issue was that the users were not told about the practice, and were not asked to agree to these stipulations. And of course, the old adage about not attributing to malice what can be explained by incompetence also applies here - if the issue got "fixed" then it might have been simply just that, incompetence. Somebondy enabled the same SSL interception on the student network that they are using for faculty, or similar.
Also, I shudder to think of the potential mess caused by allowing personal laptops to VPN in the first place.
Depends. With proper endpoint assessment tools, you can obtain some reasonable security. BYOD is kind of a rising trend, so a generally accepted method seems to be "Sure, you can connect your own laptop or tablet or whatever to the network, but you'll use Anyconnect and the HostScan has to report conformance". This mostly stems from the fact that in all the meetings folks are starting to use their fancy iPads instead of bulky laptops...and are expecting same services being available.
I've seen some customer actually think of this as a benefit - savings in IT budget. If workers are willing to maintain their own devices on their own time and all the IT has to do is a compliance check, all the better for the company.
Lync stores the info in two databases, LCSCDR and QoEMetrics. The first one has info on all sessions, other one has quality data. It's not like it's some super-secret database, MS has full specs in Technet, for example http://technet.microsoft.com/e... shows what's exactly stored in SessionDetails table.
Yes, such info *could* be used to do data-mining. Same info could be used to optimize least cost routing, gathering statistics on network performance, planning upgrades, and whatever you like. I've personally crafted a few reports from those DBs on how much folks are calling PSTN from Lync on various customer sites, so they can decide what is the priority in upgrading E1/T1 to VoIP-based PSTN connection.
It's not a conspiracy. Server admins can look at what kind of stuff you are doing on such servers.
It's a niche project, but looks like getting a good techie phone is niche these days. Uses N900 displays and casing, so resolution is not getting any better, but has lots more processing power.
Jolla might be an option once they get the QWERTY "other half" available.
Happened to me for my first real job interview. I answered "I'm really uncomfortable with lying. So if I'm working on a project where it's starting look like the product will be crap, you don't want to put me to a meeting with a customer or I'll tell him that too".
And I got the job.
Note that it was early 2000 and dotcom bubble was still going, so maybe they took me in despite of that answer, not because...
We are currently monitoring six distributed sites using http://mathias-kettner.com/checkmk.html. It still relies on Nagios 3.x core, but they are going to replace that soon ("micro-core"). From what I've heard, Nagios development started really going downhill at Nagios 4.0, and this plugin issue is yet one more such symptom.

There's plenty of legacy stuff in intranets that require flash that is *not* easily upgradeable, or at least up to the user.
Case example on where I run every now and then in work, Cisco IMC controllers (server management cards).
http://www.cisco.com/c/en/us/t...

Just get a PCMCIA network card and use network boot disks - still available for some distros. I think at least Debian still provides them.
