Slashdot Asks: What's In Your Home Datacenter?

netsavior distributed setup plus 4TB mirrored filestore (277 comments)

I have all our media files on 2 fileservers (old desktops with big hard drives), then I have a distributed webserver with metadata stored on a cassandra cluster. All 6 desktops/laptops are members, so any of them can serve up a request for file lists/images/"channel" listings. This replaced a perfectly working setup with static xml files for metadata, but I wanted to learn cassandra.

I am trying to "embrace" the cloud so my eventual setup will be to have no dedicated servers at all, but to have the ragtag collection of active desktops and laptops in my house and have server type stuff I do now be more or less distributed (7 people live and use computers in my house)

Study Finds Link Between Artificial Sweeteners and Glucose Intolerance

netsavior Re:Study evaluated sacharin vs glucose (292 comments)

it is amazingly impossible to find the ingredients online. the coke owned 'beverage institute' defends saccharin and lists a few example drinks that contain it.

It is hearsay at this point, but the DietCoke website used to list the ingredients... now they appear completely scrubbed from the internets.

Study Finds Link Between Artificial Sweeteners and Glucose Intolerance

netsavior Re:Study evaluated sacharin vs glucose (292 comments)

Saccharin is used in fountain drinks still, because then they don't require labeling, and people are only opposed to saccharin when it is on the label. That is why fountain diet coke tastes so much better,

Is the Tesla Model 3 Actually Going To Cost $50,000?

netsavior 50-80k is an insane estimate (389 comments)

Tesla Model S is 69k, the model 3 is going to be less expensive and be less "premium" for lack of a better word. If your back of the napkin estimates don't TOP out at 69k then you have no basis in reality. The article sort of points this out and says an 80k price is "pessimistic" I am going to argue that it is psychotic, and invalidates everything else this soothsayer had to say.

Toyota and Tesla May Work Together Again

netsavior Re:Bad definitions of series & parallel hybrid (51 comments)

Parallel = electric motor and gas motor are both connected to the drive train.
Series = only the electric motor is connected to the drive train.
Prius is a "power split" or a "series parallel" hybrid, which is a bullshit term that means "we are special and not just a parallel hybrid"

In the modern colloquial terminology, slang usage seems to to be
"Series" = "range extended electric vehicle" or "generater in the trunk"
"Parallel" = "doesn't work without gasoline"

In general, people don't care HOW a series/parallel/power split/monkeyass hybrid works... they just care about the "doesn't work without gasoline" part, which is the tough pill to swallow with modern "totally not parallel" hybrids.

Tesla Plans To Power Its Gigafactory With Renewables Alone

netsavior Re:Musk worship (260 comments)

I get it, I really do, but the romanticism of the electric car is far more justified than the romanticism of the Prius. The Prius is a gasoline car that is good at using gasoline. An electric car is a replacement for gasoline, a Prius is an iteration on gasoline. If you believe gasoline production/use is bad, you have to believe that electric = good, while Prius = less bad.

as far as creating an affordable electric car, everybody agrees Teslas are too expensive, even Musk.... well, that is the POINT of this factory. Batteries suck, and our best batteries are horribly expensive, the only way to make them cheaper is to make more, faster. They have a 3 year plan for a $35,000 sedan. To go from $128,000 to $69,000 to $35,000 in 8 years is amazing, and that is where the "Musk Worship" comes from. Some of the first cars were electric, and since then incredibly wealthy auto manufacturers around the world have been telling us it is all but impossible.

Ask Slashdot: What Are the Strangest Features of Various Programming Languages?

netsavior MSSQL (729 comments)

I love the various different parsers MSSQL uses, and how very wrong things can go. Run this in SQL management studio and it will work fine... run it from the command line and it will give the below error. It will find \r\nGO\r\n and treat it as a block terminator... even if it appears in comments. This is the only command that it will find and execute within comments.

declare @var as int
set @var = 10
print @var
/*
this is totally in the comments
GO
*/
print @var
------------
output -
------------
10
Msg 137, Level 15, State 2, Line 1 Must declare the scalar variable "@var".

Does Learning To Code Outweigh a Degree In Computer Science?

netsavior Learning has nothing to do with "degree" (546 comments)

If getting a degree is part of your career plan, it is probably worth it. If you expect to "learn a trade" or "see where you land" or "get an education" you are in for a huge sea of debt and disappointment.

If you are going to college to learn to be a computer programmer, that might be possible, but it will be NP hard, and I have never seen it done successfully.

There is this kind of false dichotomy that ignores the benefit of a degree because everyone confuses a college education with "learning."

The day I showed up for freshman orientation, I had all the skill I needed for an entry level programming job... I know because I started both at the same time. The people in my classes who were ALREADY coders were the only ones who did not drop the classes. You go there to learn what everyone else calls that one cool trick you saw that one time (recursion, or tree-sort, or adaptors or injection or bitwise and or whatever). You go so you can commiserate in your peer interviews about "towers of hanoi" and "9 queens." You go so you can prove to an employer that you can do something hard for 4 years. You go so you can get past the HR desk monkeys. You go so Mister CEO won't feel bad paying you 100k for doing 'puter stuff.

Learning to code is a completely different thing from getting a degree in computer science. They are married in people's heads, but they are oranges and orangutans. You don't go to the SAT to learn to do math. You don't go to the DMV to learn to drive. You go to PROVE you can do something roughly equivalent to the thing that future employers want. As bad as the comparison is, there is nothing else (and no Certifications don't do anything).

Ask Slashdot: What To Do About Repeated Internet Overbilling?

netsavior Re:little known trick for ATT (355 comments)

Ever since "digital cable" showed up years ago, people have steadily gone complacent to bullshit TV problems.

channel change lag (change the channel, count to 10, picture materialized out of pixelated garbage) - This is bullshit, VHF/netflix/hulu/hell even youtube kicks the shit out of this, it is a horrible experience
Fluxuating sound and lag when local commercial overlays are pumped into the service you already pay for, not just advertising, but also making your experience much worse, -- This is bullshit
Rebooting this bullshit machine takes 5 minutes.
What did we gain from putting up with a piece of shit hardware box to decode cable signals? A buggy as hell, Ad stuffed "guide"

This isn't unique to ATT, although their turd definitely does suck. When held to any kind of UI standard, Direct TV, Time warner, comcast, sudden-link, every single cable solution I have seen since "Digital cable" came out has been pure garbage. Bottom line, if you aren't interested in sports you are a masochist if you use Cable, and I am not convinced sports fans are anything less than masochistic, perhaps signal noise and digital picture artifacts are their fetish.

Ask Slashdot: What To Do About Repeated Internet Overbilling?

netsavior little known trick for ATT (355 comments)

If you have Uverse, pay the extra 15 dollars a month for their most crappy TV service. The TV bandwidth is through the same series of tubes, and paying their 15 dollar a month television fee removes their ability to charge you for overages. But like all ATT services, be sure to manage your own DNS settings, as their default is so horrible that all my neighbors thought their "internet was down" when it was just a DNS server from hell.

I don't actually know for sure that the TV vs Bandwidth thing is a fact, but I can tell you that I no longer get charged for overages, and my Router's stats tell me I am using more than ever, and the only change is I signed up for "limited basic" or whatever it is called + HBO (for HBO Go) and the TV receiver is sitting in shrink wrap in my closet.

U.S. Senator: All Cops Should Wear Cameras

netsavior Re:The death of leniency (643 comments)

+1 to the parent. Selective enforcement blows.
The saying goes: "If everyone is guilty of something, they can punish anyone for anything."

Don't like someone's youtube channel? Find a video which has a poster of Tinkerbell in the background and get Disney to DMCA
Don't like someone's racial background or religion, wait until they fail to stop 10 feet behind an intersection and give them a ticket. Search their car while you are at it
I commit thousands of crimes a year, and so do you. That isn't a problem with me or you, or even law enforcement. The letter of the law is so screwed up that there is no possible way to root out corruption and discrimination.

How many devices are connected to your home Wi-Fi?

netsavior 6 household members 20 devices (260 comments)

20 devices currently powered on PS3
5 iPads - 4 are required for kids school
3 phones
Kindle fire
kindle paperwhite
2 laptops
5 desktops
2 Roku
there are a few that have been on my wifi recently but were retired. dead laptops, old tablets, Nook, etc.

If there is one thing I have learned... it is if you have this many devices, you have to get solid router hardware, or you have to replace it every month or so. Routers that are forced to burn twice as bright, burn out twice as fast. My latest and most solid router to date is a Netgear Nighthawk.

Tech Looks To Obama To Save Them From 'Just Sort of OK' US Workers

netsavior Re:Bullshit (441 comments)

When Google offered me a job, I could not believe how little they wanted to pay me. 67% of what I was making at a megabank doing a small amount of very high level innovative stuff, but mostly brain-dead SOAP integrations and listening to conference calls.

That is why I laugh when I get a recruiter or ex-coworker that tells me I should go work at amazon or yahoo or netflix. The bigger the name, the bigger the h1bribe pool, the lower the salary.
