You can DDOS a server, a network, even big routers, but you can't DDOS the internet.
Cutting random cables here and there won't work either, at most you're going to isolate parts of the net.
The only way to take down the internet in 30 minutes is to exploit vulnerabilities in the BGP core routing protocol and announce netblocks that somehow (that's where something has to be exploited, bypassing filters, smaller blocks and routing costs considerations) takes the priority over other routes for every router that receives the announce.
Please stop the FUD. Did you ever run USB external drives before stating such a thing ?
I have 7 of them, and i'm seeing real transfer rates of about 40 MB/s. If FW can dedicate its entire bandwidth to transfers, that would give it a max of 50 MB/s.
50 vs. 40, not anything *terrible* like you're trying to make it appear.
It has a binary format, far more compact (and faster to unserialize) than PHP's text-based serialized format.
I won't say *far* more compact unless you are just serializing a bunch of boolean and ints, for an average string-filled packet the gain of going binary won't exceed 10-20% in size. OTOH, you are right about performance.
It handles multiple versions of the same objects (e.g., your server can interact with both PhoneNumber 2.0 and PhoneNumber 3.0 objects relatively trivially)
This is only an issue when you need to share definition files (.proto for google protocol buffers) between clients and server. Many serialization formats (including PHP's) don't need that, because they include the definition with the serialized data (slower, bigger, but simpler for developpers)
It generates code for converting each format into objects in their 3 supported languages.
Well, not needed with PHP either, a call to unserialize() will create and return all the needed objects.
So, no, not really.
Yes it is, it's just serialization which was - unlike PHP serialize() or XML - designed for small size and performance.
no wonder this was easily recoverable with such a low data density.
I don't think it would have been possible if the drive was 300gb, which raises an interesting question: do they choose small hard drives for this very reason ?
A program might run fine with 1,2,4,8, or 16 cores, but if you do some kind of odd number I wouldn't be surprised if several applications just refused to run. It will be interesting to see what kind of compatibility testing AMD has done with this new processor.
This is wrong, an application has nothing to do with how its threads end up on which cpu on a smp system, this is all done by the OS scheduler.
You are not going to plug your oscilloscope inside random parts of the chip and take measurements... The features are way too small and the only way to reveal the inside of a chip is (i guess) electron microscopy.
On the other hand, you can use yout stuff on the various pins of the running chip without tearing it open and it may be sufficient to get you what you need (keys, unencrypted data, hd dvd volume id,...)
Interestingly, SCTP falls behind TCP in the majority of cases (more latency, less bandwidth).
The exception being the HTTP tests, where I guess they used only one tcp connection to the server with no keepalive (something that no web browser would do in the real world, most opening 2 or 4 tcp connections with keepalive).
I can't see a real advantage of multi-stream SCTP over multiple TCP connections... Someone in the know care to elaborate ?
I love urban legend as much as the next guy, but this isn't exactly true. These are cell phones not two-way radios. Phone A will be talking to a cell phone tower, whilst phone B is talking to a cell phone tower, whilst each cell phone tower is talking to the two phones respectively.
Right the phones never connect directly on a GSM network, but either way their antennas are omnidirectional, so a phone talking to a tower on the opposite direction would still irradiate the egg with the same amount of energy...
A funny thing I noted is the "if you're giving a strong (audio) input the phone will emit with more power"... come on, this would be true with pure analog phones, but GSM is not and that make this claim plain wrong
A few days ago, I installed a Thermaltake TWV-480 in one of my machines. This is a power supply that inclues a front bay panel with an LCD display telling you how many watts of power are currently being used. The machine is a Pentium 4 2.4ghz with a Radeon 9600 Pro, a CD burner, four hard drives and several USB devices.
Since installing the panel, the machine idles around 50 watts or so, spikes up to perhaps 55 if I turn up the fan speeds (which is rarely necessary), and maybe 60-75 or so for a few brief moments when I'm doing something that requires heavy disk access like openning a large file (or group of files).
your panel is obviously lying.
the cpu alone may eat 50W idle (and a lot more than 55W under load), but there's no way for the whole system to run on such a low power...
why don't you try switching your 480W PSU for a 150W one (come on, it's still 3x more than needed) and tell us what happens ?
In this day and age, when magnetic storage is like $0.50 to $0.75 per GIGABYTE, I just can't fathom why a responsible admin would risk the possible data corruption that could come with compression.
yes you can, just paste this to your nearest xterm :
echo "without data compression, i'd have to pay \$$((`ls -1/root/.private/movies/|wc -l`*640*352*3*25*60*90/1024/1024/1024/2)) for my pr0n storage"
Actually the DMCA as well as its EUCD european counterpart are both implementations of the TRIPS international treaty which was brought to us by our loved and highly democratic World Trade Organization.
It also seems that EUCD is yet more restrictive than DMCA, actually the french implementation of EUCD, if adopted by the parliament at the end of the month, will simply make it illegal to publish free software .
It's more than time for all this nonsense to stop.
according to wikipedia, the Ariane 5 ECA launcher alredy made its first successful flight on february, also it did launch 3 satellites at a time during this flight...
show me *any* supercomputer, beowulf cluster of supercomputers, or whatever capable of cracking 256-bit encryption in less than a few thousand centuries and I buy it, your price...
i've read somewhere - and find it very plausible - that brute forcing a 256-bit key (meaning try the 2^256 individual values) would require more energy than the total output of the sun during its billion years life... so good luck FBI...
Although InnoDB is quite a niece piece of work, I wouldn't call it a key piece of the MySQL server software. It is just one of the *many* storage backends supported by MySQL, and it's not by far the most used (99% of the MySQL installs i've seen only use the internally developped MyISAM storage engine which btw is the default one...
And btw, people who need transactions and advanced features tend to use postgresql instead of mysql+innodb...
They have been added to the centre's existing bank of 1144 Intel 2.8GHz processors, boosting its power by 50 per cent to create a supercomputer with the equivalent power of nearly 15,000 PCs.
so they had 1144 processors, they add 500 of them (250 dual cpu blades)... how do they get these 1644 PC processors to perform "with the equivalent power of nearly 15,000 PCs" ?!
they are either comparing with Pentium 200 processors, totally bullshitting, or maybe they meant 1500 ?

For all I know they may have been at it all along, probing other parts of the Internet
I don't think so, my firewall has many public adresses in distant subnets, and I've seen the exact same patterns as the OP.
So my (informed) guess is that's actually a second run.

Not saying that's impossible, but still tough ...

you are mixing bits and bytes here, SATA2 device bandwidth is 3.0 Gbps (300+ MB/s), versus firewire 800 Mbps (100 MB/s)

not to be pedantic, but 19200 bps modems actually used a 2400 baud modulation.
Say, a library wrapper for accessing a legacy data source for which there's no scripted library?
I think this is what the ffi extension for PHP is all about

I love how TFA cautiously avoids the use of the term "microwaves" and refers to them as "milimeter waves" ... it feels so much safer ...

I think you meant Maxtor, and btw they were bought some time ago by Seagate ...
