Is LTO Tape On Its Way Out?

Cramer Re:its all about selling Autoloaders (274 comments)

From the very origins of LTO... magnetic tracking marks, just like a hard drive, and floppies before that. If the servo tracking data is ever damaged or unreadable, the tape (and your data) is trash. No LTO drive ever sold can "format" a tape.

(Yes, it makes tapes cheap to manufacture. But above all, it means not paying Quantum for their patented laser optical tracking tech -- DLT has physical tracking marks on the back of the tape.)

Is LTO Tape On Its Way Out?

Cramer Re:Shyeah, right. (274 comments)

Actually, there's an enormous difference. Disc is designed for high capacity, and thus has insanely high bit densities. They rely on significant technology to work at all. With the bits so small and packed so close together, modern hard disks tend to self-destruct if not constantly maintained. (read: powered on and left to run recalibrations) Tape is designed for long term storage, so bigger bits, less densely packed. Tape will maintain the pattern written to it for a very long time.

If your tape drive doesn't work, it can be replaced (usually -- older tech can be a problem), and the tape(s) read perfectly from it. When your hard drive fails -- bearings, circuits, or (99.999999% of the time) the firmware the cheap bastards stored on the media becomes unreadable -- You. Are. Screwed. (options: 1) throw it away, 2) pay a data recovery company $$$$ to get your data back.)

Flash drives aren't magnetic storage.

Enterprises use disc backups for two simple reasons: cost and speed. In most cases, the data backed up will be obsolete in a few weeks or months. Anything that has to outlast the quarter finds it's way to more stable storage -- tape, cd/dvd/bluray (unwise, but still used), flash drives, and/or SSDs.

Ask Slashdot: Dealing With VoIP Fraud/Phishing Scams?

Cramer Re:Sue Them or Give Up (159 comments)

The CO (switch) never cared. Despite having the ability to check/reject CLID values, no one ever has. Today, with SIP and soft switches, it's even easier, and they still don't do it. (I bet your voip.ms personal account could send out whatever it wants -- not a cutomer, so I don't know.)

Ask Slashdot: Dealing With VoIP Fraud/Phishing Scams?

Cramer Re:Sue Them or Give Up (159 comments)

There is no technological solution.

There is, and always has been. With a simple POTS line, there's no means for the caller to manipulate anything -- it's all set by the serving switch. With ISDN (PRI and to some extent BRI), the caller was allowed to set CLID fields to indicate which "extension" is calling, ANI would be set by the switch to indicate the billing number for the line, however, your phone doesn't show ANI (even if it's a ISDN phone.) ISDN was expensive, so only a business would have them, and businesses could be trusted to not abuse the feature. That has worked out so well. :-)

Every phone switch I'm aware of supports limiting what's allowed for CLID. It's obvious most (all?) telcos cannot be bothered to use this feature.

Ask Slashdot: Dealing With VoIP Fraud/Phishing Scams?

Cramer Re:This is a legal matter. (159 comments)

Actually, the MPAA/RIAA do have a court order in these cases... but just one for many IPs. When they have to file one case per address, it becomes a huge burden (and expensive) and they tend to walk away.

Ask Slashdot: Dealing With VoIP Fraud/Phishing Scams?

Cramer Re:Level3? (159 comments)

IF you take the call directly from a scammer, and the SIP call is completed...

And just who in their right mind allows random SIP traffic from the internet to reach their PBX? ABSOLUTELY FUCKING NO ONE! Page one, step one of toll-fraud: allow access only from authorized sources. So, if a SIP call is "completed", it came from your phone service provider.

If they're spoofing the caller-id, then you have NO WAY to know where it came from. Only a "trap and trace" can follow it back, hop by hop, to the origin -- one switch at a time, one provider at a time, all the way back to China (or where ever.) That's the basis for the hollywood phone trace, but in reality, it takes people combing through records to see what's going on. (unless it's crossing metered lines, in the US, it's almost a certainty no CDRs are being generated and/or recorded, and even then, only for the segment that's metered -- eg. your cellphone.)

Former Police Officer Indicted For Teaching How To Pass a Polygraph Test

Cramer Re:Well, I for one feel safer... (328 comments)

"Secret" is the most basic of our (US) government clearances. It's an entirely clerical check. It's not like you're being authorized for nuclear launch codes, but something closer to knowing phone numbers and extensions for people's desks.

(I've had a "secret clearance"; it was the .gov's equiv of an NDA.)

Ask Slashdot: How To Unblock Email From My Comcast-Hosted Server?

Cramer Re:First step is to collect data. (405 comments)

Unless you've been keeping detailed records long BEFORE the event(s) that triggered your blacklisting, odds are you'll have no record of what actually caused it. With Yahoo, you may not even know who was sent what, so you don't know who might have clicked the "spam" button. (and it used to be far to easy for complete idiots to click spam instead of delete, and not have any idea the difference between them.)

NET-23-30-0-0-1 was assigned to Comcast Business two and a half years ago. Your (apparent) netblock [NET-23-31-69-152-1] was assigned to you about a year ago. If anti-spam outfits were, as you claim, blocking all Comcast addresses, you'd've been blocked from day-one. The fact that you weren't, and have now mysteriously been blocked very strongly suggests something occurred from within your netblock to cause it. That means ANY device within your network could be the "bad apple".

ISPs Removing Their Customers' Email Encryption

Cramer s/flag/command/ (245 comments)

It's not a flag, it's a command. Support for the feature is signaled after the client hello (EHLO). It's not just hiding the indicator in the hello, but actively blocking the command.

The issue Goldenfrog whined about was a simple oversight from Cricket Wireless(?). That's the default behavior (even today) for Cisco firewalls -- which is why everyone with a clue disables (or at least tweaks) that idiotic inspection rule.

The Disgruntled Guys Who Babysit Our Aging Nuclear Missiles

Cramer Re:Science fiction comes to life, again (176 comments)

Right. Manned by a pair of people inside a bunker that would take days to breach from the outside -- by design. One of the goes nuts and kills the other, he's got plenty of time to rig shit. Someone on the surface would have to notice this, and then get maintenance crews to the site(s) and into the silo(s) to physically disable the launchers. Every step in that chain is measured in multiple HOURS -- assuming anyone outside even notices before a missile comes flyin' out.

The Disgruntled Guys Who Babysit Our Aging Nuclear Missiles

Cramer Re:Science fiction comes to life, again (176 comments)

And if the stories are true, for a very long time, the silo launch codes were (still???) set to zero in protest to having those installed in the first place.

All this assumes a mad man in a silo couldn't figure out how to bypass the proven lax security measures and light one off on his/her own.

First Detailed Data Analysis Shows Exactly How Comcast Jammed Netflix

Cramer Re: Multiple CDN contracts? (243 comments)

So I should be able to demand Verizon install ("host") my server(s) for free as well? Not going to happen.

Netflix is a FOR PROFIT BUSINESS. They can pay for services just like everybody else. (speaking as Verizon) Why should I bear the cost of hosting their business? It isn't costing me customers. And I'm sure as hell not going to give those asshats at Cogent anything; they're being paid boatloads by Netflix but won't buy the interconnects to support 'em.

Yes, there are small(ish) ISPs hopping on the Open Connect bandwagon. For them, it's a cost effective solution vs. the alternatives -- lost customers, or additional expensive bandwidth. Verizon (et. al) simply aren't going to play those games: Cogent can buy the bandwidth necessary to support their customers, or Netflix can find a different (preferably direct) path.

First Detailed Data Analysis Shows Exactly How Comcast Jammed Netflix

Cramer Re:Why rely on peering? (243 comments)

They have (had?) more than one provider. They have their own ASN - AS2906. It's readily apparent they suck at traffic engineering. (or they let it happen to try to push Open Connect.)

First Detailed Data Analysis Shows Exactly How Comcast Jammed Netflix

Cramer Re:Netflix, in the parlor, with the fireplace poke (243 comments)

Netflix has other ISPs, and significant traffic engineering power at their disposal to get traffic to flow how they like. The simple fact that people could "VPN around" the congestion is proof Netflix could have used a different path to that user. However, it's easier to whine to the media in lame attempts to get Open Connect in the door. (i.e. host our business for free.)

Plus, they bought bandwidth from some of the cheapest providers around, who everyone knows isn't going to care when they fail to deliver. (Cogent is infamous for "peering disputes".)

Cramer Re:Common Carrier (243 comments)

Not "for free". Settlement Free Peering is based on a mostly balanced flow of traffic. The instant that ratio moves from 1:1 to 100:1 (as happened when Netflix switched to their in-house CDN), "free" isn't in the room anymore.
