If youre the first into the ASIC world, you would be absolutely crazy not to run your ASICs for a few weeks before sending shipments off. Its like playing the stock market or blackjack with a 30% discount: statistically, the advantage is so great that you cant lose.
Except in this case theyre not even risking money-- theyre just pushing the ship date back a few weeks.
Edit: Im actually calling complete BS on your statement. You can do it with consumer drives, maybe, but at 2TB / drive youre probably hitting $4500 in storage alone, plus $2000 for a card that can drive 20 disks, plus dual massive 700w+ PSUs, plus ~$1000+ to hold your storage array online long enough to shut down, and $1000 in 10gigE cards. That doesnt include RAM, motherboard, processor, chassis, and backplane for all of those disks.
You might hit that mark with bottom of the barrel SATA drives rather than SAS, but i would really hope that youre not going that route.
And again none of this addresses the massive issue of array corruption. One bad shutdown with insufficient RAID battery backup could make the whole array inconsistent, killing all of your data. Thats why you dont use RAID as a backup.
I can get 150TB of LTO5 storage (native capacity) with 2:1 compression and built in AES for $2000, and an 8-bay tape library for another $3k. I dont have to worry about array rebuilds, power, disk crashes, power surges, or uptime.\
You could always restripe to RAID 5
Please tell me you arent in charge of anyone's backup. You're suggesting a whitebox build with software RAID 5 with consumer SATA hardware (has to be at those prices)-- did i mention RAID 5 on 12 drives? You might as well go RAID 0 for all the redunancy youve bought yourself. Heres a hint: Never ever use RAID 5 on an array with that many drives, as you massively drive up the chance that a second drive will fail before your incredibly slow rebuild completes.
Clearly tape is a problem, which is why just about every enterprise relies on it for their disaster recovery. Say it with me: Online RAID storage is NOT A BACKUP. Its failover, or hot/warm spare, but anything that is kept onsite and online is by no means a backup. Anyone who designs such a system as their backup is a liability. What happens when a surge or a fire hits your fancy array? You plan to rotate 16 disks in and out regularly?
Any sort of eugenics that is embraced will shortly become mandatory, and necessarily involve telling people who may and may not mate, and with whom. Brings back shades of the "kill the infirm and sterilize the unsound" policies of Nazi Germany. Gotta breed that master race, dontchakno.
This isnt even hyperbole. Eugenics by its nature will necessitate telling some people that they are inherently worth less than others, in a moment undoing years of civil rights activisim. Doesnt mean much if "black and white" isnt the issue if it just shifts to "blond-hair-blue-eyes vs those genetically unsound romani", huh?
Well, the FCC is independent dontchaknow. Its apparently no longer in the executive branch, so its none of Obama's concern what it does.
At least thats what the response seems to say. Meanwhile, on other fronts hes busy creating powers which the president never was supposed to have, like the ability to override already passed legislation by simply ignoring it.
I had kind of wondered right off the bat why a company advertising devices which print money wouldnt use them to print money.
Possibilities: 1) Theyre phenomenally dumb, but still capable of making ASICs 2) They used the ASICs ahead of time, then sold the ASICs once the value propisition of said ASICs had plummetted 3) They realized that there was no more value to BitCoin than to roulette
None of those sound terribly appetizing. Sure you can make money there, just like you can with horse racing and house flipping.
Disk is "easier" until you start having to juggle more and more data, and want longer retetntion periods, and realize what a PITA it is to have to have all of your storage online at once. Then you realize what a liability it is to have your backups always online to begin with (malicious users, surges, EMF pulses from lightning strikes, someone drops the server), and all of a sudden tape sounds really really good. Need more retention? Buy another pallet of tapes at under $20/TB. Server room went up in flames? (this actually happened to a client of mine) Tapes offsite have you covered.
An array like you mentioned would have to be whiteboxed to meet the budget of an LTO drive, and even there its doubtful (24TB Raw is gonna run you close to $2000 once you figure in all the hardware). A new LTO4/5 drive is generally gonna be under $2000, and an 8-bay autoloader can be found for under $4k.
The real beauty of tape is that its easy to store offline. A nasty surge could easily fry all 24TB of your storage at once. The platters may be in tact, but have fun doing a platter swap with your backup data. Say it with me now: Online RAID arrays are not good backups. All the best disaster recovery scenarios will involve offline media transported offsite so that a single nasty lightning strike cant kill all of your data (either thru surge or through magnetic wiping).
The drives apply compression that achieves 2:1 on a Reference data sample. Considering that the tapes are usually NOT backing up video / audio / binaries (user data is usually more important than executable content), such compression rates are commonly seen in real-world scenarios.
This isn't usual; different data is differently compressible. I
This is true, but it IS usual. LTO compression also selectively applies compression; it will not attempt to compress JPEGs. Luckily JPEGs dont tend to get backed up.
Yea, and whats wrong with Communism? All of those mass genocides just gave it a bad name. Surely we can do it right if we try again.
Sorry, some ideas are poisonous, and can be identified as such from the results of every time they were attempted. How many times should we attempt eugenics before concluding that it just leads to genetic discrimination, forced euthanasia, and forced sterilization?
Heres a tip to all voyeurs out there: dont probe random IPs specified as "vulnerable". You probably wont get noticed, but if you are you can get in a whole bunch of trouble. "Unauthorized access" means you unless you have permission.
It also costs about $100 extra and requires a whole bunch of extra configuration and knowhow.
Theres basically no reason not to use your router as your NAS as long as it doesnt have any vulnerabilities and it meets your performance need. Simplicity is a good thing, you know?

90 to 1 they dont store their backups as jpegs. The licensed originals are stored by someone, and they surely are not using lossy compression.

Anyone whose business depends on images is almost certainly not backing up lossily compressed data. PNG, maybe.
Anyone want to guess how the company making those devices would know the performance stats of the ASICs if they arent ready to ship?
Heres a hint: Theyre probably not waiting on manufacturing-- theyre waiting for someone to get around to shutting the devices off.

Turns out its just a memory dump from when a processor bug caused a kernel panic.
I had understood that anyone with half a brain was on ASICs now.
Then again anyone with half a brain wouldnt be joining the pyramid scheme so late in the game.
There is a difference between caching, and QoS by type, and QoS by source.
The first two are not a problem: possibility for abuse is very low, and they both benefit the consumer quite a bit. The third is the problem.
Depends what provider youre using. Not everyone is well off enough to have global servers.
We might fine them some of the money we've been giving them, that might send a lesson.
I'm pretty sure it's hacking only when the other end has an expectation of security.
Im not aware of that being a factor. Whether it is illegal or not is up to the courts, but it truly is best not to tempt fate.

you also probably just technically broke the law.

Pretty sure the attack is on an Asus router which if i had to guess is running some unix variant...
not sure if you're trolling or what, but you really never know on slashdot.

Watch out for SSL bugs in dd-wrt.
Drones generally have been used for "enemy combatants". Doing it for an unarmed US citizen would be a much Bigger Deal.
Pretty sure that was never stated, and if i had to guess he would be jailed, not executed.
