Is LTO Tape On Its Way Out?

scsirob Re:So how is the price... (275 comments)

Ask AWS for a quote to restore those 48TB. No really, please so. And then come back and tell us how the math worked out.

Some of our customers had calculated that AWS and tape were on par from a storage perspective. AWS perhaps even a bit cheaper. But any and all benefit is gone the instant they needed to restore anything substantial. Think multiples of $10K...

Is LTO Tape On Its Way Out?

scsirob R&D: Only three companies left (275 comments)

Tape is great for archive purposes. It would be a shame if LTO dies.
The biggest threat to LTO is the lack of vendors developing drives. At this time only very few companies do R&D for tape devices. IBM, HP and Oracle are the only serious players.

Oracle develops only Enterprise class drives (T10K), not LTO. The market for those drives is quite small, which means the R&D cost needs to be recovered from a relatively low volume. That makes them bl**dy expensive.

HP develops LTO. They have to do R&D for LTO only, as they have no enterprise class drives. LTO is considered commodity so margins are too low to spend a lot on R&D. They will therefor struggle to be cost effective.

IBM develops both an enterprise class (Jaguar) and LTO tape drives. From a tech perspective, IBM are in the best position, as they can develop new technology for their enterprise drives, recoup cost in that segment, and then commoditize the technology in their LTO drives. Unfortunately IBM no longer wants to be a hardware company.

This does not bode well for tape technology in general. I've made a good living from it writing software for tape drives, but I guess all good things come to an end.

Is LTO Tape On Its Way Out?

scsirob Re:A bit of wisdom (275 comments)

.. and the only reason they are the same speed is because it's your source that determines the limit, not the destination. A decent LTO-6 tape drive will outpace any set of harddisks behind regular RAID controllers.

Drones Over Greenland Give Insight To Pollution's Effects On Melting

scsirob Re:Propaganda (81 comments)

Interesting observation that black snow is 'thanks to human activity', so near to active volcanoes spewing dust, rocks, lava etc. But no, must be us humans.

Largest Sunspot In a Quarter Century Spews Flares

scsirob News for noobs? (46 comments)

At one time the tagline for Slashot was "News for nerds, stuff that matters".

This stuff matters, but adding an explanations for the impact of solar flares on RF communication makes it obvious that Slashdot is no longer for nerds.
Sad..

An Air Traffic Control System For Drones

scsirob Drones will not be accepted (77 comments)

A single helicopter already turns heads and if it hovers for too long, people will complain about the noise. How do you expect this to work when hundreds of drones are buzzing over our heads every day? People will get very aggressive and drones will be downed in any way possible.

Until there's a silent anti-gravity system (McFly, are you listening?), general use of drones will not take off..

Four Dutch Uberpop Taxi Drivers Arrested, Fined

scsirob Re:I'm sorry (282 comments)

It very much is, unless you work for the Dutch government or the established taxi cartels like TCA.

Dutch people are sick and tired of being over regulated and over taxed. It is a bloody insult that you need a permit to drive someone from A to B *IN YOUR OWN PROPERTY*. And is no less than a crime that Dutch government thinks it is OK to take over HALF of your income. 52% if you make a decent living, and all that to pay for those annual 50K 'positive' immigration of people who add nothing to Dutch society. That's modern slavery for the Dutch!

Mobile Phone Use Soon To Be Allowed On European Flights

scsirob Re:Wrong... there is a risk (96 comments)

Not sure who modded you away, but I for one fully agree. If this has to happen, setting a time limit or a time window might be the best balanced option.

Mobile Phone Use Soon To Be Allowed On European Flights

scsirob I'd pay for a non-phone flight (96 comments)

Having the screaming kids or the fat, sweaty guy next to you is bad enough. Last thing I want is 200 people yapping on their mobile for several hours. Time to start 'Quiet Airlines', no-go for kids and phones.

Why the Z-80's Data Pins Are Scrambled

scsirob Re:C=128 (167 comments)

Too bad no company ever came up with a killer 8-bit machine. Z80 CPU, more than 64 kB RAM, sound and graphics like SID and VIC-II.

Really? Ever heard of MSX? See: http://en.wikipedia.org/wiki/M...
It came with graphics, sprites (TMS9918/9929) and was a standard design carried by several manufacturers.

IBM Solar Concentrator Can Produce12kW/day, Clean Water, and AC

scsirob Re:OK (268 comments)

I have 19 solar panels (Yingli 255Wp) on my rooftop. Just ordinary ones, nothing fancy. They produce 34 kWh on a sunny day. So why is 12kWh from this contraption special? Even with the 20kW(h) of heat added, my panels still top theirs.

ISIS Bans Math and Social Studies For Children

scsirob Re:Actually against Islam (981 comments)

ISIS is islam in all its gory detail. Muslims all over the world get up in arms, and riot over as much as a pencil drawing of their bloody prophet, but are entirely silent over the atrocities performed by IS in the name of their religion. Therefor I conclude that they all to some degree agree with the methods of IS.

There's a recent video on Youtube, where Brigitte Gabriel puts it plain and simple; The Peaceful Majority is Irrelevant. Look it up.
Islam is the worst cancer ever to come to humanity.

Link Between Salt and High Blood Pressure 'Overstated'

scsirob I can simply ignore all health and diet advice (291 comments)

Just about everything that is bad for you today is being negated a few years later. Can't find the link today, but at one point "research" showed that jeans were responsible for higher risk of cancer. So I will just continue to live my life and enjoy it to the fullest. If something kills me, at least I had a good time.

UN Study Shows Record-High Increases For Atmospheric CO2 In 2013

scsirob I want my money back (427 comments)

For the past decade I have been taxed the hell out of, all for the savior of our planet. All to reduce emissions, lower pollution and stop Global Warming (which has conveniently been renamed to Climate Change).

Apparently all for nothing. Taxing the hell out of ordinary people makes zero difference on CO2 emissions. So can I please have my money back???

Grand Ayatollah Says High Speed Internet Is "Against Moral Standards"

scsirob Re:The key bit (542 comments)

I find it quite interesting that sharia which has to be taken literally and has not changed in a thousand years, has anything to say about internet speeds. So somewhere over 1000 years ago a bearded guy sat in a tent, writing "Thou shalt not surf the interwebs over more than 14.4k Baud...". These guys are goood..

Facebook Experimenting With Blu-ray As a Storage Medium

scsirob Re:Everything old is new again. (193 comments)

^^^^ This. Tape is very robust. Last year I restored 15 tapes with old Netware 5 from SDLT. For test I have read 8mm MP tapes from the early 90's and still can read every bit off of them.

I have more trust in reading back a 10-year old tape than any writable optical media, or even harddisks for that matter. Leave a harddisk to gather dust for several years and chances are it won't start up.

Facebook Experimenting With Blu-ray As a Storage Medium

scsirob Re:Why not the "boring" Tape storage? (193 comments)

That is a load of b*ll.. LTO tapes are serpentine recording and tape positioning is pretty fast. The average time to reach any file on a tape is half the time it takes to spool it from one end to the other.

You are not 'trying to find' anything on tape, the software does that for you. Check out LTFS.

No more Groklaw

scsirob (246572) writes "Word is out that PJ has pulled the plug on Groklaw. A source of education on US law, patents, SCO versus IBM and much more stops. PJ simply cannot justify to herself to stay connected in a world that is under constant surveillance. The Internet as it stands today is a threat to humanity, she explains.

Slashdot Poll: Reader age distribution

scsirob scsirob writes  |  more than 2 years ago

scsirob (246572) writes "Today's logo about the demise of Ceefax included the comment that most readers were born after Ceefax was introduced. This, combined with the 15th anniversary of Slashdot, would make a great poll. "How old are you?" with options in 10-year intervals."

scsirob writes "When I first started playing with computers (25 years ago), they were relatively easy to understand. Intel 8080 chips, TRS-80 Model 1 and CP/M isn't exactly rocket science. I tought myself how to program in assembly and later in C. I now design little gadgets with embedded processors and program them, and I write diagnostics software on a range of O/Ses. My kids (8 and 10 years old) are starting to get interested too and want me to teach them how to do all this. But I find that their level of expectation is waaay to high. They want to design games without any basic knowlegde. So my question is, how do you 'bootstrap' kids into computer knowledge to a comfortable level without turning them off or disappointing them?"
