Comment Ensure offline works (Score 2) 508

" I assign papers that must be typed, I have papers turned in online, and I plan to freely refer to texts, videos, and other resources that are available online."

Typed could be done with a typewriter. The onus is on YOU to scan if you need electrons. While it certainly is harder, having to think before typing can provide the student with some benefits as well!

Provide pointers to offline texts that should suffice (books, libraries, etc. still exist).

Videos and other resources can be viewed, when they have access at school, library, or tablet (Amazon is rumored to have a $50 one in the wings).

Since you aren't teaching at an elite private school, make sure that you aren't depriving your students of the chance to learn!

Comment Nasal rinsing ... use some care (Score 4, Informative) 151

Using a Neti pot, NealMed or homebrew .... it seems still sensible to either:

1) Boil water, and hold at temp for several minutes (a "hot pot" e.g. http://www.zojirushi.com/app/p... typically holds the water at a boil for 4min) or
2) UV sterialize http://www.steripen.com/advent... as an example

While one can use distilled water, often it sits around potentially growing something (but probably nothing brain eating) so making it fresh has advantages.

Yes, these pests are rare; but the results dire enough one should take reasonable care before putting water up one's nose these days.

Comment Re:Yes (Score 1) 698

Well ... yes... it does say arms. But it says it in context "A well regulated militia being necessary to the security of a free State, the right of the People to keep and bear arms shall not be infringed"

so the arms it speaks of are those that would be employed by "a well regulated militia". Other than military police, what militia related activity would involve stunning an opponent?

But the posters who have commented on the insanity of permitting deadly weapons (viz. weapons whose normal operation is to kill) and forbidding non-lethal (when used as intended, have low risk of killing) made a very sound point.

Comment Re:Grants to Researchers vs Institutions (Score 1) 120

Aye, this does seem to the crux of the dispute. Many researchers have always acted as if the PI is the owner ... but that's not what the grant language typically actually says.

So I conjecture that is what the Court(s) will have to decide "is the grant language (and germane government policy documents) to be read as written, or reinterpreted as has been the custom?"

Once upon a time, Courts gave a lot of weight to the language as written. Sometimes they still do. Other times, they seem willing to pretty much turn the language on its head. IANAL and its unclear to me just when they decide to set aside the language as written and when not to.

Given the $$ in play (both directly and for downstream royalties) I'm sure neither Institution is going to give up easily. The implications for other researchers will be far reaching ... so I will be surprised if a bunch of amicus briefs aren't filed.

Comment Depends on the SSD (Score 5, Interesting) 327

See http://blog.macsales.com/21641... for an example of a properly designed SSD.

kext signing is a GoodThing for security. Making the system less secure so that lazy implementors are protected isn't a good trade off.

Apple *should* have provided a better upgrade experience so that users wouldn't be surprised, or end up with unbootable systems. Users that don't want to have kext protection CAN turn it off see http://www.cindori.org/trim-en...

To me this is akin to Apple's desupport of WPS ages ago. It took everyone else a while to figure out that WPS was a major security hole (indeed, its still there for most consumers).

Comment Re:Lisp, Forth, APL, J, Prolog, PostScript (Score 1) 387

APL and J are useful for doing the sort of ad hoc big data analysis that R is also popular for.

The speed (or lack thereof) of your terminal isn't really the issue, its being able to think in matrix/vector transformations. A skill which is actually more important today than 40 years ago.

Comment Re:Mainframe Programmers (Score 2) 387

"...access to a mainframe system"....

Well, there is more than one kind of mainframe, and they aren't much alike. But let's assume you really mean IBM zSeries. You have several options:

1) Take a course. Many schools have IBM sponsored classes with access provided.
2) Find a copy of the "Hercules" emulate http://www.hercules-390.org/
3) Sign up for ANY university class to become a "student" and apply to IBM http://www-03.ibm.com/systems/...

Also note the growing popularity of Linux on zSeries systems, so your Linux skills can be directly applied.

Comment Move Corresponding (Score 1) 729

Removed from modern versions of COBOL, the traditional "MOVE CORRESPONDING" was unique. Given two records with differing layouts, MOVE CORRESPONDING would shuffled the values based on the names (putting in default values where needed, or tossing aside unneeded ones).

Comment Clearly there IS a question (Score 1) 506

90% of accidents (or more, depending on the study) are due to human error. So the DMV insistence on putting the humans back into the drivers seat is actually counterproductive. "there's no question when it comes down to the safety of those on the road." ... the question is are the other humans on the road more or less safe with the google vehicle operators able to override the computer?

While I'm not interested in being an early adopter of this or most automotive technologies, there are lots of questions when it comes to safety. It is a pity that government hardly ever uses science or logic in the decision making.

Comment What was the performance impact? (Score 1) 1

The "article" is just a pointer to the bugtracker entry which is good but lacks any clues as to measured performance.

LTO has been a win in commercial workflows for many years. Obviously it can be an obstacle for debugging (when entire call trees are eliminated or collapsed single stepping in the debugger is problematic) and if build times become excessive the results may not be worth the cost.

But in the end the real payoff is runtime. Without impressive speed ups for user critical to acceptability operations it is just air guitar!
