Seagate’s triple whammy: Disk numbers, costs, and flash

Ammaross Danan

Re: Areal density

"The reality is that traditional mechanical HDDs are nearing their end of life due to physics."

You must have stopped reading about HDDs once you bought an SSD. HAMR alone will allow HDDs to hit 18TB by 2018 (see Toshiba's CEO discussion on the matter if you think I'm just personally speculating). Combine that with additional density advancements in HAMR and adding in SMR (for write-once-read-many situations [netflix, home media]) and you'll get a great density boost.

So no, HDDs aren't EoL at 10TB (current size).

That said, flash certainly has a greater potential to out-density (yay, new term!) HDDs, but likely at a significant price delta for a long time.

Re: There is money to be made.

If you think recovering a few hundred GB over the network is bad, just imagine how long the "go to the cloud!" punters will take to restore (not to mention if you're the unfortunate that has a data-cap or rate limit soft-cap). SSDs are markedly better for OS and applications, but for large, sequential storage like RAWs and vids, disk is still ideal (cost for size mainly, as speed is fairly moot). Those VMs would best benefit from an SSD though, just like an OS/app drive.

WordPress.com ditches PHP for Calypso's JavaScript admin UI

Ammaross Danan

Re: wordpress is bloatware

Fifteen tables is certainly reasonable. I take it you didn't actually pay attention to what those tables were used for?

I'd also assume your website design template (if you actually abstracted it from your display script) was terrible in-line styling or poor CSS at best? Perhaps you were not even escape-checking your input fields or base64-encoding enabled? Compared to a quick whip-it-out setup, it may feel bloated, but it's versatile enough to be used by more than the one person you wrote for.

Muted HAMR blow from Seagate: damp squib drive coming in 2016

Ammaross Danan

Re: The slow death of the HDD

You are making the mistake of assuming HDDs are trying to compete on IOPS. They're not (at least since SSDs went mainstream). They're large data drives. Your new 30GB game (most games are large indexed archives), multi-TB video collection, TBs of photos, etc. You don't get 8TB of spinning rust to put your OS and apps on.

Hard drives are still excellent with the one thing they're good at: large sequential writes and reads. HAMR will even improve the other thing they're good at: offline (or nearly so) data storage, as NAND requires data refresh cycles (similar to RAM, but with a larger timeframe between refreshing), which means data on an SSD that's tossed in a drawer will (most likely) not be readable in 3 years.

128TB SSD by 2018? Toshiba promises much, delivers ... a little

Ammaross Danan

Re: "and a few enthusiasts looking for speed in such things a gaming."

"Most data on people's hard drives isn't accessed enough to make access time even an issue for the most part."

Yes, but it's Windows and program files that matter. Picture folders benefit substantially too. If you think putting media on an SSD is a waste of bits, try explaining to an "older person" how to use a "D" drive...

Re: it's not about the hardware

No, their array does not lose data. It has, for us at least, struggled under a write-heavy ~800 IOPS load with 2 hybrid shelves. Lesson learned: don't buy their lower-end (weak single proc) shelves if you are using dedup+compress with ANY flash in your system.

Pirate MEP: Microsoft's walled garden is no consumer pleasure park

Ammaross Danan

Re: Unauthorised peripherals?

Did everybody miss that they merged their XBOX and Windows policies? The "peripherals" bit is a carry-over from the XBOX preventing things such as modding, "game genie" type devices, aimbots, etc, unlicensed knock-offs, etc. Now, the fact they left it in the Windows policy is throwing the door wide open, but it's way more likely they just left it in the verbage rather than having any particular device range (or walled garden) in mind.

Nude celeb iCloud hack: Feds seize Chicago man's computers

Ammaross Danan

Re: Someone else?

They're likely looking for a C&C bot or somesuch on the hardware. Any hacker worth his weight (or even most skiddies for that matter) will have a small gaggle of zombies they can proxy through. They'd have to find the C&C hub and access logs for THAT (or just monitor it) in order to find the real culprit.

To your point, that sort of activity could/should have raised a flag at the least. However, a large company (or even a hotel) would easily exceed 500 iCloud accounts by merely having guests on their wifi. I fain to think what a Starbucks or metro open wifi NATs in a day.... Even with flags, they could be red herrings. I'd still do it if I was the sec bod, but I'd also start whitelisting some.

HGST shimmy shimmy shingles its way to a 10TB spinning rust drive

Re: Cannot imagine wanting under any circumstances

You must not be familiar with HAMR. Shingled is a stop-gap while HAMR drives are matured. The predicted density of HAMR drives is certainly higher than 20TB over the life of the technology.

Windows 10 Device Guard: Microsoft's effort to keep malware off PCs

"But if an enterprise is saying 'Hey, sign this for me,' it will be done with a key that only works for that company."

Re: Why do I get a bad feeling about this...

You also forget that the K-branded i-series CPUs (e.g. Core i7-4790K, et al) do NOT have VT-d (as opposed to the non-K CPUs such as the Core i7-4770 which do have VT-d). Fortunately, people interested in K-branded CPUs are likely intelligent enough to not need this particular form of malware protection.

"But if an enterprise is saying 'Hey, sign this for me,' it will be done with a key that only works for that company."

Now if it can be done for individual users that have some legacy software (such as the original Starcraft....), I think this would work well for home users. Otherwise, you'll severely limit the amount of software one is able to run...

Infosec bod's brag: Text editor pops Avaya phones FOREVER

Ammaross Danan

"Indefinite"

So, he's claiming the "indefinite" compromising was due to his assertion that: “My definition of firmware updating is trading known vulnerabilities for unknown ones,” thus still finding some way into the device through currently-unknown means...thus "the industry needs the ability to retrofit arbitrary devices with operating-system agnostic host-based defences" of which he happens to own a company that does exactly that.... I see a conflict of interest in his assertions (read: points made are likely exaggerated for a sales-pitch opportunity).

Trading Standards pokes Amazon over 'libellous' review

Ammaross Danan
Boffin

Re: Perhaps

Actually, the review is correct as stated: it blocks emergency services callbacks. If those said services follow the prompts, they can get through, however, so it is a omission in the review for that point.

As for telemarketers, some DO have the ability to directly interact with the dialer (to hit that 5* combo) if desired. However, telemarketers are incentivized to talk to people who don't want a sales call so much they buy hardware to block such calls, as it likely won't lead to an actual sale. I'd certainly result the call as a "no answer" and move on as quickly as possible. (Yes, telemarketers enter results of a call after each one and nearly all the time pick "no answer," even if you just pick up the line and hang up). Best thing to do is "please remove me from your calling list." The marketers are required, by law, to remove you when requested. Be cordial though, because even then, you might get resulted as "no answer" just to piss you off when their system calls you back after the ~3hr retry window.

Re: Those "6 months" are your advantage to make money, eejit.

"Then all of a sudden it becomes a touchscreen device."

Perhaps that was because someone (LG, Sharp, Samsung itself) came along and said: "We will be mass-producing these new screens with touch capabilities in a few months....Want to make a new device with them?" Of course one would abandon the old Blackberry look when touchscreens became viable. Apple didn't move to touchscreens because they were ludicrously expensive and they were willing to take a hit just wanted to help humanity....

My work-from-home setup's better than the office. It's GLORIOUS

Ammaross Danan

Consumer vs Business

To actually address the questions raised at the end of the article:

Businesses don't (shouldn't) use consumer-grade equipment due primarily to scale. You load 20 work laptops (or more) onto your "cheaper" AirPort or Netgear/etc WiFi device and you'll be locking up, dropping, rebooting it frequently at best.

Google Docs or Apple iCloud would work well for documents and such, but I don't know many workplaces that are willing to toss their accountant's spreadsheets and ledgers out into the ether, let alone their HR documents. Does Google store their project code in Google Docs? Nope (at least not the public one). If you use the consumer versions of "cloudy" file sync, it's usually a single external USB drive attached to your WiFi device or (if you're lucky) something you can install on a home server. Most companies have a hard time just scattering their potentially-sensitive documents into the wind though. Use this in a healthcare environment and you'll be sued at best.

If you want to go further into storage servers (a whitebox FreeNAS vs a VNX or the like), there's pros and cons, but you can't convince me a bank would host their infrastructure on your whitebox FreeNAS. Sure, it's loads cheaper than their Ipsilon or Hitachi VSP, but I doubt that would persuade them. You could try selling Macbook Airs to a MAS90 shop too. Just because it works at home for Facebook and iTunes, doesn't mean it has business-class features.

Traditional RAID is outdated and dying on its feet

Ammaross Danan

Re: broken RAID

An easy way to sidestep that patent would be to do what ZFS or BTRFS does: checksum each block in addition to the usual "raid" parity/mirroring. Then, even a "RAID0" is protected from cosmic-ray-bit-flipping with a rebuild-capable checksum on each block. Of course, these two file systems just use the raid controller as a JBOD interface so the system doesn't halt up due to a bad block on a single drive anyway....

Re: Congratulations

"I tend to see far more multi-application deployments on Windows"

I'm not sure what world you live in, but our environment is highly isolated because Corporate Application 1 requires Software Stack 1 which is DIRECTLY incompatible with Software Stack 2 which is required by Corporate Application 2 and 3.

Not only that, but who wants to be rebooting their mail server, domain controller, web server, etc all-in-one SBS server just because an Exchange patch was pushed out? Windows still requires reboots for several items. *NIX environments can be patched/updated on-the-fly (got to love the ability to overwrite a file currently in use) and the components simply reloaded.

How many apps does it take to back up your data?

Ammaross Danan

Re: Speaking as a humble home user

@AlexV: "Of course, the disadvantage of this is that it is slow, as it always has to copy all the data. However, if you don't actually copy the data, and only assume that it's still the same because it isn't supposed to have been modified, how would you know?"

You could use a program such as rsync, which will (by default) checksum files to determine if contents have changed and delta-copy the differences to the destination, so this protects against bit-rot on the destination side, but your checksum datafile would help you find bit-rot on source side. Of course, you could just use a checksumming filesystem such as zfs or btrfs and not have to worry about it in the first place...

Re: You're not using MySQL's built-in replication???

@Trevor_Pott

I have to practice politics every day too. You've had to deal with a wider range, due to the nature of contract work. I, like yourself, tend to end up implementing compromised solutions IRL, because that is exactly how the world works. With office politics, as with armchair quarterbacking on the internet, you recommend the more-ideal solution first, then let it get whittled and compromised down into the end result. But yes, it is the sysadmin's (or more accurately, the CIO/CTO's job) to emphasize disadvantages or shortcomings of implementations. As a consultant, it remits to the consultant to point out those things too.
