If the world is as dependant on GPS coverage as TFA would have us believe then we need more GPS jammers out there causing disruptions to force everyone to fix their bugs before there is an outage and shit really hits the fan.
It is NOT acceptable for lack of GPS to cause havoc. Especially in San Diego of all places... Where Navy ships have a habbit of continuously emitting harmful interference.
Pedo, bipolar, rapist.... All I want to know what really happened with this teacher?...Obviously the students were upset or tweaked by something.....what was it? How can they leave such details out of TFA??!?!?
Subsidize in the beginning until it does become profitable? If that were the case, then MAYBE. But the thing is, many of these technologies cannot scale or if they can, they do not become more cost effective.
We in the West are pretty clean for the most part - it's getting India, China and other developing countries to clean up and they don't have the money to subsidize any technology.
??? Dude wake the fuck up... China is currently kicking ass and taking names in both wind and solar production. The US BY ITSELF is right now responsible for half of the worlds pollution...yet it accounts for only 1/22th of global population.
We're fucking up the world more than anyone else while making other countries pay the price for our actions. "Clean"... no I don't fucking think so.
If you ever wondered why people hate the police it is because of the few officers with god complexes doing shit like this spread far and wide by word of mouth.
I don't consent to having myself recorded on CCD cameras everywhere I go... Do I get to press charges against my local 7-11 for secretly recording my slurpee making activities??
This is rediculous and EVERYONE knows it. If the charges are not dropped there will be lots of outrage and public pressure to change the law and then LEA looses a punitive threat to cover their asses... You watch it will be dropped like all of the other ones before it.
You can blame the choice of a language ill suited to the task.
Java may not be the best choice for a real time environment, for one thing there's the garbage collection to consider. A language that stops from time to time to perform some internal task isn't what I would choose for a time-critical system where human lives may be in danger.
Personally I would be pissed if they did any heap allocations at all during steady state. Using a language which virtually denies one the right to breath without requiring a heap allocation is inexcusable.
the new system runs Linux, but the article also says "java". no surprise that a j2ee system would turn out be a bloated, slow steaming pile of dung. Sure, efficient coding can be done in Java, but far too often too many layers of canned commercial libraries from a certain j2ee framework vendor are employed
Java...whaaa? WTF is a garbage collected language doing anywhere near ATC?
The way things are going my next phone will be an N900.
Given multicore ghz processors and large memories why the hell do we have to continue to tolerate bastardized java, incomplete c libraries and vendor specific languages (objective c/.NET...) for mobile platforms? Why exactly? Android interoperability is a fricking sorry fragmented mess which drifts further from linus's tree with each passing day... while Windows 7 and iphone are restrictive walled empires.
I question the very premise of why there needs to be any distinction between PCs and mobile devices at the system level. You should be able to scale UIs and do reasonable power management without having to rewrite everything... There are enough transisters in todays mobile devices to make it work.
In effect, although you could make a Mac OS X trojan or virus that installs a keylogger, it would be exceedingly difficult to do so without the user doing something careless.
OMG nobody gets it do they...The millions of zombie PCs out there...are not there because someone explioted some vulnerability... They exist in large measure due to SOCIAL ENGINEERING.
Apple has had sufficient market share since the beginning of consumer viruses and malware. There were plenty of Mac viruses back when their market share was far lower than it is now. It's absurd to claim that there are essentially zero malware for Macs because of market share, when their market share is large enough for thriving third-party software and hardware. Market share plays a role, but is not *the* primary reason.
What this indicates is that Apple is being proactive in making sure Macs remain as secure as they are today, and not resting on their laurels
Can I ask what makes OSX more secure than windows vista/7 when faced with the problem of a user being tricked into loading malicious software? Complete with instructions for bypassing any UAC/security warning prompting they may encounter?
I would love to see someone provide a cogent answer for this one simple question... Most successful attacks on the masses are social engineering that expliot no systems vulnerabilities of any kind.
I get your perception = reality = security idea but it is in fact a lie... security by obscurity.. It is critically important to understand the underlying reality...
The IPhone is a good model of protecting the user from themselves but personally I would only submit to that level of lockin and single vendor control after I am long since dead.
How do you protect the user from themselves while still preserving choice and an open ecosystem?
You could do least privledge but even then malicious code has access to all of the data the user cares about! You could virtualize and sandbox everything but programs often need to interact and interchange data.
It is in fact a very difficult question...one that no general purpose operating system vendor currently has an luser proof response.
Yes, we all know the FUD has been flying, he was asking for actual data.
Still waiting for the first Mac OS X virus in the wild...
That noone is even bothering to write viruses for OSX speaks volumes for the situation.
I've been hearing how the MAC platform is secure...since...back before they even had a preemptive kernel or a sane security model when apps and the OS crashed regularly. This is/was obviously bullshit.
Perception is everything... windows is viewed to be less secure because it is by far a bigger target. All social engineering / botnet efforts are focused on it to maximize attacker ROI.
If an OSX luser received an email telling them to download and run a program to see if they won $1million... what precisely would make the outcome of that exercise any better than the same situation twoard a windows vista/7 user?
I imagine in either case the attacker would include instructions for bypassing UAC/security prompts as is quite normal for many popular legitimate software installs from the Internet today.
Fooling lusers is easier than finding vulnerabilities and a system is only as secure as its weakest link.
Can we please get off this hobby horse? The Tolkien estate isn't "censoring speech," it's protecting its trademarks, which it is required to do by law. If this guy had made a bunch of buttons for himself and as many of his friends as wanted them (all three), nothing would have happened.
So any geek shirt mentioning Micro$oft or referencing unix or apple without permission from the trademark owners is violating trademark law?
I'll choose you amongst the hordes to respond to. Feel flattered;) iPads are finding huge traction amongst medical and flight and construction and education and science visualization and you name it, all because there is FINALLY a low cost, Stable, robust, and well implemented platform for data interchange in the field as a comoditized thick-or-thin client. Are you telling me palm or windows phone 7 was what you saw driving the future of these industries and programmer growth because companies were invest in a platform that might actually mature? Sometimes I swear, android was only meant to give out of work java programmers something to do;) How's windows doing with that low power thing? How's sony doing with releasing, improving, and using free OSS software? Yeah, right.
Are you seriously arguing for objective C over.NET... as a basis for a comoditized client? Really?
For home users with a linux router set an HTB queue/w maximum egress rate to modem a little less than than your sustained upstream rate. At least this worked for me... never had problems with saturated upstream causing huge lags after doing this.
After reading this guys buffer bloat rant I largly agree with him with some exceptions:
1. What does multiple TCP sessions have to do with circumvention of congestion avoidance? TCP congestion avoidance needs to work with lots and lots of TCP sessions at once not just one or two. HTTP 1.1 sessions need NOT be short lived. I don't see why a large number of TCP sessions can't all be subject to congestion avoidance...responding individually to the conditions they see? How does this work to effectivly bypass congestion avoidance? I've seen this talking point in a few places but noone has ever explained WHY this is so. I can see an argument based on a static suboptimal initial congestion window but HTTP 1.1 supports pipelining...
2. Two connections per server is not sufficient for browsers. TCP is a stream protocol with head of line blocking... High latency links will never use the available bandwidth properly unless they either use lots of sessions or start with massive windows which is not good for congestion. There is also a problem of ordering dependancies of resource requests within the web content. Without lots of concurrent fetches the user gets to wait longer for page loads. The presentation sounded to me like someone either not understanding necessary details of TCP and higher layer considerations or trying to have their cake and eat it too.
Lastly we don't need to replace HTTP - we need to replace TCP... HTTP over SCTP would be a much more significant improvement than any reasonable change to HTTP. No matter what you do to HTTP you still have to live with the underlying transports limitations!
Sometimes I truely wonder if useful information technology has plateaued...
It seems any more innovations in communication and information publishing are about maximizing the sales channel rather than providing value to the consumer.
Now I know how poor rice farmers in India must feel as the seeds from their rice harvest can't be regrown after some clever biotech company introduced a terminator gene to protect their IP and profits.
It is quite possible for GPS to measure 25 MPH and Radar to measure 40 and they both be correct.
Radar measures instantaneous speed while most GPS software records position deltas over much much larger time scales (many seconds) to conserve resources (battery,cpu,storage)
The 5.0 invest great deal of time and effort selecting areas where vechicles are most likely to exceed the posted limit at a given locale even if only for a few moments.
CFLs contain mercury; cheap ones can leak UV, take time to start up, most are not dimmable, expensive and contain high frequency electronics that can cause RF interference.
Normal lights suck 5x the amount of energy as CFL and LEDs but are cheap and harmless and no you don't get to disregard the extra energy needed to manufacture CFLs and LEDs.
I should be able to choose the type of lighting I want out of principal and especially given crappy unproven unacceptable alternatives. I don't turn on the incandescent lights in my house very much or for that long..the amount of energy they consume is therefore trivial as percentage of my total usage.
If you want to legislate lower power consumption incentivize the proliferation of ground source heat pumps and energy efficient blower motors. Or hell if you really cared you would find a way to keep desktop computer vendors from producing computers that consume >100 watts continuous while sitting idle doing absolutely nothing.
Most likely your system is misconfigured and sending misdelivery reports rather than rejecting the smtp request in realtime or worse (open relay)
Comcast and Verizon are reacting by shutting you down...you have to beg to get it restored from what I understand...
There is no good solution for most of us other than to just relay thru comcasts SMTP server.
Comcasts user networks are in the subscriber block lists of many RBLs however typically business class accounts are exempted from these lists.
For outgoing mail if you can't send directly your best bet is to configure your SMTP server to relay all messages thru comcast smtp.comcast.com which is less than ideal.
Comcast runs with aggressive dns timeouts and their mail system does not properly translate DNS timeout to a temporary condition.. This sometimes cause emails to valid destinations in distant countries with slower links to bounce.
We have racks of windows and linux servers and they just work..0 OS specific problems ever..I mean for at least 5 years.
Are the people complaining about windows crashing running consumer hardware without ECC memory and crappy lowest bidder 1U non-redundant PSUs going crowbar? Reliability thresholds of major general purpose OSs is all noise compared to physical hardware attributes nowadays.
It is NEVER a good idea to reboot ANY system of any kind without first understanding what the hell is wrong with it. Various services especially database service if arbitrarily rebooted may take hours (As in OFFLINE) to recover to a consistant state.. I've seen it happen..too many times....it is not a lot of fun telling retarded sysadmins they have no choice but to sit on their hands and wait hours for a system to come back online because they got up and pressed the big red button.
Hubble didn't work out of the box. From the moment it was deployed there was a spacewalk to unfold one of it's solar panels. Then there was a famous 'set of glasses' fix to it's optics. There have been hardware upgrades and gyroscope fixes.
It takes only one small glitch for this to be an expensive piece of space junk
JWST operates mostly in the far infrared where there are a lot more tolerances vs visible light telescopes. The new gyros are a totally different technology... much more reliable - less wear items.
There are ways to hedge complexity with redundancy and testing but there is always risk.. I don't think your sentiment is lost on anyone working this project.
For experimental/observational science 'the universe' and 'the observable universe' are the same thing, as by definition that's all we can know actually exists. If you think there's a distinction between the 2 terms you're the one making an assumption.*
This is incorrect. The observable universe is different at every point in the universe. A distant object under our observation may be influenced by events outside of our light cone which we can only indirectly observe.
We can not see further than 13.75 billion light years because this is the distance that the light has travelled since the universe has become transparent. This happened 300,000 years after the big bang.
The distance light has really traveled is much much more than the speed of light as it is also dependant on hubble expansion..depending on your POV.. at some point in time and distance you reach a point where you can not see further regardless of the universes age because the portion of the universe under observation expands faster than the direct propogation of information. The universe (in terms of energy from the big bang) is currently hundreds of times larger than our directly observable universe.
Microsoft has said a lot of stupid things like their grand schemes for combating spam with computational "puzzles" or charging money per email.
Their idea consumers should run something like NAP or be forced to go thru a certification process is just another money making scheme couched in nonsense.
The reason why these technologies fail is that ultimatly you end up going down the path of asking a liar if they are being truthful. Don't expect a compromised botnet zombie host to tell you it's anything but 100% healthy and trouble free.
Hate to break it to you. Your likely to see better results attacking the worlds root name servers.
BGP implementations for all their faults do have countermeasures against propogation of frequent state changes as if they even need them.
I don't know how many zombies you need to successfully attack a single ordinary 10GB link.. Just setting a basic CIR or priority queue for BGP sessions would prevent the success of any such attack.
If you want to slow down the Internet why not just have your botnet army consume bandwidth..find a few thousand of the longest paths with the most hops (amplification) and pounce... You won't shut down the Internet but you may succeed in pissing off a lot of people especially if your attack favors International links.
I'm afraid it takes a little more creativity than ddos to crash the Internet.
