Ask Slashdot: How To Pick Up Astronomy and Physics As an Adult?

TechyImmigrant Some Math Required. (220 comments)

I recommend "The Theoretical Minimum" books as a good starter to get you through to the level of mathematics needed to be able to read the quantum math and vector/tensor calculus used in field equations. Statistical calculus also.

Once you have these under your belt, comprehending the real physics textbooks and papers will be unlocked.

This stuff is not hard are impenetrable, but the language is if you don't know it. The language isn't hard or impenetrable. E.G. Vector calculus is much simpler that algebra. Just find a good book or teacher that doesn't blind you with procedure over concepts.

Court: Car Dealers Can't Stop Tesla From Selling In Massachusetts

TechyImmigrant Re:Car Dealers should ask why they're being bypass (154 comments)

My algorithm for buying a new car is:
1) Spend about a year deciding what I want and/or need.
2) Simultaneously, start saving the cash.

It's not like you can't tell when a car is nearing the end of time, relative to whatever your own level of love for car maintenance is.

When the time comes, you know what you want and you've got the cash, which makes the bargaining rather trivial.

SanDisk Releases 512GB SD Card

TechyImmigrant Re:1024-fold (210 comments)

Base-10 units are not in any way more correct than base-2 units. They are merely more consistent with the way scientific units are generally used (but less practical, since base-2 units correspond to how data is actually addressed and alligned).

I do not oppose people using base-10 units. I do, however, oppose people redefining well-defened units. The idiotic extra i (KiB, MiB, etc.) should have been inserted in the new (base-10) units, not in the existing units. This creates unnessary ambiguity.

I was referring to the internationally standardized system of units. Not the intrinsic merits of any particular base.

Harvard's CompSci Intro Course Boasts Record-Breaking Enrollment

TechyImmigrant Re:Linux, cryptography, HTML and JavaScript. (140 comments)

Yes, types are only a theory, and an unproven one. That's why I skip types.

I don't like your type.

Harvard's CompSci Intro Course Boasts Record-Breaking Enrollment

TechyImmigrant Re:Linux, cryptography, HTML and JavaScript. (140 comments)

So call it a 'programming' course. Computer science marginally overlaps with programming, but a programming course is not computer science.

While we're at it, we could stop calling Computer Science a science and admit it's applied mathematics with silicon thrown in.

That's computer science?

What about algorithm complexity analysis, type theory, normal forms and well, computer science.

iPhone 6 Sales Crush Means Late-Night Waits For Some Early Adopters

TechyImmigrant Re:I just want the new Nexus. (222 comments)

>is because there are many standards

The problem with creating the one true standard is that in the US the PCI-DSS people would want to do it, and I've never seen a more incompetent bunch of standards writers than PCI-DSS when it comes to payment security.

Link Between Salt and High Blood Pressure 'Overstated'

TechyImmigrant Re:Eat real foods, mostly veg, not too much (291 comments)

>By the sounds of it the only real damage done by salt is kidney damage and that is if you eat too much of it.

Actually too little salt will kill you. Too much salt (in the normal range of dietary input) has no detectable detrimental effect. A 10 ton block of salt on your head will kill you, providing you're in a suitable strong gravitational field.

Any claim I've seen of salt causing kidney damage has been thoroughly debunked.

Do you have any data to support your claim? It's new to me and I have been paying attention.

IACR Finally Gets Around to Repudiating Mass Surveillance

TechyImmigrant TechyImmigrant writes  |  about 4 months ago

TechyImmigrant (175943) writes "Following the focus on government mass surveillance resulting from the information revealed by Edward Snowden, many organizations involved in security and communications put out statements essentially repudiating that surveillance. As of yesterday (May 15th 2014) the IACR (International Association for Cryptologic Research) who one might expect to have a position on this, has finally one year after the anniversary of the leaks, got around to making a position statement.

"The membership of the IACR repudiates mass surveillance and the undermining of cryptographic solutions and standards. Population-wide surveillance threatens democracy and human dignity. We call for expediting research and deployment of effective techniques to protect personal privacy against governmental and corporate overreach."

So the crypto guys don't like it either. Now we know."

Unemployment. It's just too good..

TechyImmigrant TechyImmigrant writes  |  more than 7 years ago

I am now into my second week of unemployment. I have a job offer and start next Monday.

This would be great except I'm really enjoying unemployment. All the work related stress has been lifted from my shoulders. I have no travel planned, no economy seat hell. I got to write some code for fun. I've got a whole lot better at playing the guitar.

Perhaps somebody could give me a few million dollars. Then I could retire and live a stress free life.
