Ceres [...] is believed to have a mantle composed almost entirely of water ice that makes up one third of the body's mass. 200 quadrillion metric tons of water ice should be more than sufficient
But when we start mining the ice there, what will we do with all the Woolly Mammoth skeletons we did up?
It looks like you want to get rid of all JavaScript in web pages.
He doesn't, but he makes a good point that "2%" performance isn't good enough, and you should avoid javascript if you can.
I consider this most important for projects like Firefox OS, which are pushing a platform for slow, mobile devices, where Javascript is the only programming language available.
What's a better way to present interactive forms over the Internet that doesn't involve reloading an entire 100 kB page whenever the tiniest bit changes
In my extensive experience, reloading the page every time is actually still FASTER and makes for a more responsive experience. Compare gmail with JS or in classic mode... Classic mode isn't as shiny, but it sure moves a lot faster. Or look at Netflix's queue... Insane delays from clicking the "move to top" arrow, until it actually happens, or the delete button, while reloading the page on each button press would happen in a fraction the time, and would work far better on low-end devices (and they wouldn't need a super-crippled "mobile" version of their site).
A tiny bit more load on your server, in exchange for a much more responsive client-side experience. A bit more bandwidth usage, but compression and caching of all other page elements should make it pretty insignificant.
Maybe he does filtering, or operates a proxy, or transparent caching?
Filtering is no problem. I was managing extremely large, very aggressive firewall rules on full 100Mbps connection with a 200MHz Pentium 2 processors, many years ago.
Proxies don't require much CPU power at all, unless we're talking about man-in-the-middle SSL. And you can do all the caching you want if you add storage via the included USB port.
Maybe he does fancy traffic analysis? Maybe he does complicated multi-level QoS?
I would expect any decent home routers to be fast enough to do all that for slow, home internet connections. Having to use a USB-ethernet NIC probably adds a lot of overhead (assuming high speed internet) that could be avoided entirely with a proper device.
Maybe he has a landing page for open wireless that is separate from his encrypted wireless/LAN?
OpenWRT/DD-WRT should be easily able to handle this as well.
Maybe he wants to be able to handle a large number of connection states that crashes lesser devices with not enough RAM? A least that's why I use a small netbook instead of one of the many cheap routers I've purchased over the years...
You can shop around for devices with more RAM. You should be able to track a rather impressive number of connections with just 32MBs of RAM in common devices, so I seriously doubt you actually need to use a netbook.
Stand Your Ground applies after some attacks you. All the evidence indicates that Martin started the fight by sucker-punching Zimmerman in the nose.
OR, Martin saw that a man carrying a handgun was sneaking up on him in the middle of the night, and was fighting for his life. He COULD have been "standing his ground" (though the law isn't really relevant).
In summary, get a cheap old laptop/netbook, and configure it accordingly. A laptop with a broken screen can be had cheap as chips.
Bad advice... You're wasting a LOT of power, and you're spending a lot more money, for a device with lesser capabilities.
You not only need to buy the laptop, you're also buying USB ethernet adapters, and a separate network switch to connect to it, while home APs/routers have all that built-in.
Just get something with a USB port that is compatible with DD-WRT or OpenWRT. I know an 8-port D-LINK DIR-632(a) has been available for $40 on Amazon for the past 6 months, which I'm sure ends up FAR cheaper than your solution, and will lower your power bill.
could easily man-in-the-middle any session they're interested in.
Yes, but MiTM is the complete opposite of "tapping all internet communications", which is what I said SSL protects against. Are you disagreeing someone else here?
If the NSA is interested in you, they'll just send a couple spooks to break-in to your house and install key-loggers, so the SSL trust thing isn't that relevant to most individuals.
After 2 minutes playing with ixsearch, I find the results to be TERRIBLE, and have no interest in using it further. Anyone can put together a crap search engine overnight, it takes a lot of work to make it "good" and they haven't done that.
And when I talk about search engines, I don't pretend I've used every single one that has ever existed... I was just referring to the most popular ones, and ixsearch doesn't remotely qualify.
The best benchmark you can make is something that is identical to your intended workload; eg play a game or use an application on several systems, and see which feels better to you.
And that's exactly what benchmarks are supposed to approximate. If they aren't doing that, it's because they are bad benchmarks.
People can't go and get hands-on with every system out there, and even if they couldn't, they can't just install all their own software on it and try it out for a few days... so we need some objective measurement to help narrow down the field, and give some general indication that X is fairly fast, but Y is pretty slow...
But, wasn't, like,...an unarmed kid shot and killed ?
Nope, he wasn't a kid at all. He was a rather large and muscular young man. It's only the press that kept showing photos of him years earlier, as a little kid.
The prosecution asserts he wasn't unarmed, but was reaching for Zimmerman's gun... When someone is reaching for a weapon, we don't classify them as unarmed, even if that might technically be semi-accurate.
And it's long been accepted that you can defend yourself from an unarmed attacker, with a weapon. Again, that's if we're assuming the prosecution's side of the story is accurate.
At no point did the victim ever do anything that warranted harassment or stalking.
Doesn't matter. It's still not legal to assault someone who is harassing you. And it's not reasonable for Zimmerman to have expected that harassment would result in someone's death, hence no manslaughter.
There are laws in several states (not sure about FL) that hold you responsible for whatever happens in the commission of a major crime, but harassment certainly doesn't qualify.
There are a few other scenarios where Zimmerman might be liable for some crimes, but without an eye witness we have nothing to indicate any of those happened, either.
Personally, I'd rather have this scrutiny directed at drunk drivers, or some other group who are really directly responsible for far more deaths.
I'd also like to throw-in the fact that DDG is a big proponent of SSL as well. Their website redirects you to their SSL site, and all their search results will send you to the HTTPS version of a site, if it exists (eg. Wikipedia). Things which other search providers do not do.
So, in the context of the NSA tapping all internet communications (which we know for a fact they have been doing since 9/11/2001: https://www.eff.org/nsa/hepting), DDG also provides much more privacy and security than any other major search engine, which don't take these steps at all.
When did you work with the Oracle DB? 1995? Tablespace management: use bigfile tablespaces and autoextend if you need lots of data
Bigfile wasn't introduced until 10g (the previous version of Oracle), and there were some specific limitations that prevented up from using it, but I don't recall what they were.
and there's a script to recompile for you
Right, but it's not something you're just going to stick in crond and forget about. It's another unnecessary job for the admin, which is okay because I have absolutely nothing else to do with my day than the care and feeding of Oracle? Is that it?
The problem is plain and simple, no other databases need this level of babysitting. They just do the sane thing, automatically.
Syntax for expdp: expdp help=y.
Yeah, I know, but the syntax is still cryptic as all hell, and takes several tries to put together a working 3-line expdp/impdp command, with just a couple remaps...
Oracle administration is not black magic
No, it's just crufty, tedious, painful, and a lot of completely unnecessary work, which is what IT is supposed to be freeing people from. Postgres gets all this stuff right, while Oracle gets it all terribly wrong.
and the high availability/disaster recovery solutions are really the best there is.
Postgres is catching-up quickly, and doing it in not just cheaper, but also much more flexible ways.
FWIW, when you're faced with the option, go with Postgres if at all possible. Oracle is a crufty mess that's painful black magic to administer. There's sufficient documentation out there that you CAN manage it, but it seems to be made up of nothing-but dark corners and ancient cruft.
I hate, hate, HATE always having to manually manage table spaces, data file size limitations, recompiling invalid objects, the HORRIBLE, painful, not entirely documented syntax of the tools (eg. expdp), the admin hostile tools that make the MS-DOS command-line look futuristic (sqlplus), etc. From an administrative perspective, Oracle is a nightmare in comparison to the relatively approachable and user-friendly Postgres.
Clustering is the big thing that Oracle (RAC) does well that Postgres can't yet touch. If you've got many thousands of customers using your service at any given time, you don't want to have to dick around with having only a single DB server.
Postgres 9.x does have the option of streaming replication to a hot standby server, so there's *some* opportunity for HA, but that's still a long way off from Oracle RAC with a four-node, multi-master DB always up and accepting requests.
If your application does mostly reads of the DB, then read-only slaves are a reasonable alternative that Postgres can do, but you're still bottlenecked on the really mission critical writes to the DB.
Postgres is a really good option that keeps getting better. But if you do go with Postgres, just watch out for the frozen XIDs. I hate having to juggle those stupid vacuum processes.
Right, I must work for Delta, and I'm just fooling everyone by keeping all their planes from crashing over the past several decades. It's a cunning plan, I don't know how you found me out.
How about tipping your wings over about 40 degrees to the left with a sudden reversal to the right less than 100 feet from the ground on final approach in zero cross wind? Sound safe to you?
You didn't crash, so yes, it sounds like it was, in fact, safe. I'm sure the pilot knows a wee bit more about flying jumbo jets than you do, and certainly much more about what happened in that particular situation, so I'll go with him on this one.
And it's nice how you decide to damn an entire airline as unsafe over ONE maneuver on ONE flight, by ONE pilot. Are you convinced he's going to be flying EVERY Delta flight you get on? Do you keep tabs on his career to make sure he doesn't change jobs and start flying with on of your "blessed" airlines? And that close to the ground, it sounds like the airport's fault, for having another jet or other obstruction in the way that your pilot had to dodge in a hurry... And since passengers don't have front-facing windows, you really can't have seen enough to say that wasn't the case. I guess you should never fly into that city again, either.
I'm not into cattle car airlines. Nope, my experience with Delta has to do with personal in-seat experience
This thread is about flight safety, and you specifically said you felt "unsafe" with Delta, while the actual FACTS say you couldn't possibly me more wrong. And no, your anecdotes and general feeling aren't facts.
If you've got some other stick up your ass, fine, (why should I care?) but don't pretend that safety has a dammed thing to do with it.
I can't get a job because I haven't got the experience. I can't get the experience because I can't get a job. Catch 22.
Lower your salary requirements significantly, and a company is much more likely to take a chance on you. Then, it's important is to cultivate a handful of references, because every employer demands at least two. HR folks aren't that bright, so you could probably fake them if you had to, but it's best to just get a few folks on-board with how awesome and hard-working you are, whether it's your boss, or someone else higher up the chain.
Once you've got your references, it's time to jump ship. Update your resume to include your experience, and a few projects you've completed, and send it out. You can stretch the truth on your resume, but you'd better have a great explanation if called on it, and it's entirely counter-productive if you're going to have to hedge and weasel your way around the subject in interviews. If you're not getting calls and e-mails, throw in every last relevant keyword you can come up with, because the reality is that your recruiter has been replaced with a very small perl script. But you better know something about the subject if you do get an interview.
When prospective employers ask for your salary history, politely decline, otherwise they'll assume paying you ~$5,000 more than you currently make will get you to jump at the offer. They may assume you're underpaid when you decline, but I've actually done this in the other direction, looking to flee a company, and not wanting to scare off employers that can only pay slightly less than I was already making, because... It really is true that employers assume you're a stupid mercenary who will always go to the slightly higher-paying job.
And give them the stink-eye while they're telling you anything about promotions and bonuses... The cake is a lie. The bonus will be insignificant, and your salary will be increased each year to just match inflation, and nothing more. If you're super amazing, you might get an extra percent or two in addition, but that's all. Long gone are the days of a "starting salary", where you'd get a major increase after proving yourself for a few months... They're already sure of you, or they wouldn't be making any offers, as the costs of a bad hire are substantial.
And be prepared to move fast. Companies won't wait for an employee more than 2-weeks, and you have to give your current employer 2-weeks notice, that gives you all of a single weekend to prepare yourself for a switch from old job to new. That can be absolute hell if you have to relocate closer to the new job. But until your resume and your bank accounts are nicely padded, that may be what you have to do. Any gaps between employment are red flags, so either cover them up, or be prepared with an impressive explanation.

When two people are fighting over a single weapon, they're both armed. It's an extremely simple concept, and playing dumb won't change that.

TOAD doesn't help me do an impdp from a file.
TOAD doesn't allow me to make a change to 6 different RACs at the same time, but a command-line tool can be pretty easily scripted to do so.
In short, Oracle is still quite painful even with TOAD. And for those without the money (or that don't want to use Windows) there is also TOra.
Bigfile wasn't introduced until 10g (the previous version of Oracle), and there were some specific limitations that prevented up from using it, but I don't recall what they were.
