Elon Musk's Proposed Internet-by-Satellite System Could Link With Mars Colonies
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.
Ask Slashdot: Sounds We Don't Hear Any More?
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.
Granted, the speaker was turned off...
Ask Slashdot: What Should We Do About the DDoS Problem?
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..
Ask Slashdot: Who Should Pay Costs To Attend Conferences?
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.
The MOOC Revolution That Wasn't
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...
John Romero On Reinventing the Shooter
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.
Reformatting a Machine 125 Million Miles Away
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.
In the New Age of Game Development, Gamers Have More Power Than Ever
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.
Who controls the HVAC at work?
So I checked "everyone with open access". That open access is restricted to me and my wife.
Gunshot Victims To Be Part of "Suspended Animation" Trials
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...
School Tricks Pupils Into Installing a Root CA
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.
How much time do you spend gaming compared to 10 years ago?
Sounds a bit like nostalgia isn't what it used to be.
For me, gaming has been significantly less over the last few years. Is it nostalgia that games used to be better? Not actually. In the last few years I've played one "recent" game that I've paid full price for - Skyrim. Couple of years ago I played a lot of World of warcraft, but I couldn't stand Kung Fu Pandas. I do pick up some games off Steam Sales, and these have included e.g. FTL and Bioshock Infinite, but neither had really any staying power.
Recent games I've played:
- Quest for Glory (entire series, I to V)
- Wing Commander I & II
- X-Wing is ongoing right now, hoping to move on to TIE fighter soon
- Legend Adventures (Gateway I & II, Eric the Unready)
- Dungeon Master
Of course, I remember all these, having gone over them a lot of times before. As such, they don't draw me to the screen as much as they did on previous iterations - hence I play less.
Anyway, I'm really hoping that the new "indie" projects will be successful. I've shelled out money for Star Citizen, Shroud of Avatar and Tides of Numenera. Hoping for a good, modern replacement for Wing Commander/Privateer, Ultimas and Baldur's Gate/Torments, respectively. If even one of them pans out, it'll be a good year.
Microsoft Lync Server Gathers Employee Data Just Like NSA
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.
Microsoft Lync Server Gathers Employee Data Just Like NSA
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.
Ask Slashdot: Life After N900?
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.
Blowing Up a Pointless Job Interview
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...

Nagios-Plugins Web Site Taken Over By Nagios
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.
Headhunters Can't Tell Anything From Facebook Profiles
As the others have said, tailor your resume to emphasize that you are jack-of-all-trades.
I'm a CCIE and have a doctorate in computer networks, have authored an RFC, and now approaching 20 years of experience in the field, which supposedly puts me into the camp of network expert.
Expect, in reality, my work in last six months has consisted of e.g.:
- Database design, operations and reporting (MSSQL and Mysql)
- Suddendly familiarizing myself with using hardware load balancers with Microsoft Lync (well, at least somewhat related to networking...)
- Writing a Python-based software for black-box testing microcontrollers
- Deployment, integration and other support work for an Asterisk-based Contact Center/PBX system ...yeah, of course there's been the other bits that I'm supposedly better suited for (firewall experties, some dimensioning for network devices, and so on), but the position is pretty officially jack-of-all-trades.
So if you are one, just proudly wear that badge. Of course, it's hard to tailor a resume for buzzword-searching headhunters, but as far as positions are concerned, one of the good signs I've seen for a true "JoaT" job ad is one where there are very few *specific* requirements (only something like "experienced in the field") is listed, and then in the "this counts as an advantage" column they have every acronym under the sun...means they don't really have a specialist position in mind, and might mean that they don't actually know what the job is. They are going to go over the resumes and actually tailor the position *for* you.
Windows 8 and Windows 8.1 Pass 10% Market Share, Windows XP Falls Below 30%
My wife is interested in getting a new laptop, as her old one is running XP and starting to be a bit slow for the indented purpose (video editing). They use Windows 7 at work with corporate desktop, and she'd like to have that at home too. Only problem: If I take a look at any laptop available it pretty much comes bundled with Windows 8.
Technically I have "downgrade" rights if the computer comes bundled with Win 8 pro, but I have heard that there are a ton of problems with getting proper drivers and so on (laptop manufacturer might not even provide drivers for Win 7).
Also, I'd still like to wait a bit, since I'm going to upgrade the house's wireless to 802.11ac and laptops are just now starting to arrive with the gigabit wireless bundled. So if it's troublesome getting Win 7 working with new machines right now, I wonder how next-to-impossible it will be by the end of the year.
