Comment Re:Is it the year of the Linux desktop yet? (Score 1) 110

Right now, today, I have a P3 desktop running CentOS6/32 as a network monitor. It's old as the hills. My phone beats it handily in performance. But it runs on about 15 watts, and does the job so reliably that, in 10 years, it's never skipped a beat. It started with the original RedHat 6.1. (before RHEL was a thing)

I know it won't actually make any records, but I'm sure it's one of the oldest 0.01%, maybe even 0.001% of computers in terms of durability. It would be a remarkable machine if it wasn't otherwise so unremarkable.

Wish I had mod points! So, I'll agree, blah blah.

It seems absurd to have lameness filters that seem to specifically target code on a site that caters to the coder types! And the 4 minute limit is just silly. Back when it was still publicly shown, I had karma out the yin yang. I'm sure I still do, even though it's no longer displayed in any form that I can tell.

Slashdot trumps Reddit for quality of articles, Reddit bests Slashdot for UI and comment participation, though posting on Reddit has become such a land mine I don't bother unless I'm on a very small/exclusive subreddit)

Comment Re:Hydrogen next? (Score 1) 175

The spinning disk era is coming to a close, and I welcome it! The issue is that while storage capacity has, for decades, increased almost exponentially, the actual performance of the HDD has remained virtually flat. A typical HDD spinning at about 7200 RPM can store 4 TB of data or more, but can only serve about 150 seek operations per second. Physics, she is a bitch, you know? So while you might be able to store 500 million files, it takes a month to copy them.

Everywhere I look, Enterprise or "performant" storage has moved to SSDs. We moved our DB servers 4 (5?) years ago to SSDs and saw at least a 95% reduction in query times involving disk operations. (EG: not cached) For us, spinning rust is the new tape; SSDs (or RAM) anywhere performance matters, and spinning rust for archival use. For our session cache, we use a RAM drive.

Comment Simple explanation (Score 2, Insightful) 165

So, your program allocates some memory. Should it initialize the memory to make sure it's all a bunch of zeros? Apparently, Nvidia doesn't think so.

So, a program running on your OS requests some memory. Should the OS initialize the memory before handing it to the application? Apparently, Apple doesn't think so.

Either answer is right.

* The destruction of the Firefox web browser thanks to numerous fucking idiotic changes being forced on its users by Mozilla.

... Moves designed to protect users from MalWare. Of course that's "destruction"...

* The destruction of Linux as a viable OS, especially when used on servers, all thanks to systemd being forced by all of the major distros.

I use Linux extensively. SystemD has been a very minor speed bump. All the people screaming and crying about systemD haven't been able to down out the simple fact that SystemD works just fine and carries numerous benefits.

I personally don't care enough about the other issues to comment.

Comment Methodology? (Score 2, Interesting) 122

Sorry, but with silly results like this, I have to ask why such a small article so vapid of meaningful content was posted on Slashdot. Shouldn't paid shill articles be a different color or something?

No mention was given as to how this ranking was accomplished, and the list given at the bottom of the article doesn't even match the headline (where 2 and 3 are MySQL and MS SQL Server, and Microsoft Access beats Cassandra.

Any DB ranking that puts Access in as a top contender should definitely back up their claims - extraordinary claims require extraordinary evidence!

Comment Re:SmartTV, Dumb Executives (Score 1) 89

We *have* a Samsung 4k "Smart" TV and we don't use any of the smarts - at all. What drives it is the XB One, or the Android TV Stick. I'm not even sure how to use the "smart" part. But it said "Smart" on the box...

I have no doubt that the "smart" feature is something they added to make it more appealing in some way, but why?

Comment Random ramblings (Score 1) 106

Years ago, with a then-ubiquitous Moto flip phone at my hip, I "invented" what I called the "Urban Commando Phone" - the cell phone already had a clock, why not add things like flashlight, garage door remote, TV Universal Remote, etc. so that instead of having dozens of devices, you had one to "rule them all".

I had no idea, at the time, of the types of convergence that would come in the form of the smart phone, which has all of these and many more either available built in
or easily available.

The term "ubiquitous computing" has been used for decades, and when I first heard the term, it was to convey the still-radical idea that every home would have a computer.

Computing seems to come in stages or "generations", where each previous generation generally powers or enables the next one. Mainframes became infrastructure for Mini computers, which (eventually) gave way to PCs, which then merged with Mini computers in the Internet revolution, which then gave birth to the smart phone era.

Following this trend, the "next big thing" will use Cell phones, PCs, and Servers to extend their capability. And this is already happening. My cell phone has a small cluster of devices that surround it that it interfaces with: Bluetooth headset, folding mobile keyboard, smart watch, etc. We are just beginning to innovate with these standards-based technologies to develop the true "IoT" that is coming; the things that link to our mobile phones to enable things we haven't begun to imagine.

Some examples that I've seen/heard of include all manner of medical devices: insulin pumps that use software on your smart phone to adjust or recommend insulin administration. Devices that provide the ability to test for common diseases "in the field" inexpensively, serving field medics and impoverished areas alike. Payment systems that use our mobile phones and networks to augment or replace credit cards.

And on and on. As always, the game is just beginning!

Comment Re:Rsync could have done this too! (Score 1) 150

Well, sort of....

We switched from rsync to ZFS replication for our production environments and the difference in performance is rather extreme. (and why we made this change)

Medium sized file system, 12 TB and a few hundred million files. Doing a backup with rsync took days, and it was all just tied up in IOPs, even if the number of files changed was rather small. At this scale, it takes more than 24 hours just to get a listing of files.

Switching to ZFS with nighly snapshots and replication dropped backup times from days down to minutes. Add other features like clones, compression, hot error checking (scrub), hot swapping and RAIDZ, and it becomes pretty obvious pretty quickly that if you're serious about data you should seriously consider ZFS.

ZFS on Linux is pretty easy to install and it's been rock solid stable of our use in a 24x7 heavy use environment.

I've been following the development of the Transition with the hope of having one. Right as the Transition looked like it was actually going to be a thing that not only flew but might actually be sold at some point, they announced this turd bomb of the TF-X with it's magical properties.

As soon as I saw the announcement, I was like WTF? From the description I wondered if it was going to be made of unicorn farts or faerie dust...

My guess is that their flying car design was scooped by the far better looking and more ready AeroMobil and they panicked.
