Amend the US Federal Do Not Call Act

The present Federal Do Not Call Act is ineffective. I think that the Federal "Do Not Call Act" needs to be amended substantially to deal with this situation:

1) Penalties need to be adjusted for the inflation that has occurred since the 1991 passage of the Act. I suggest they should be adjusted annually by the greater of the annual Consumer Price Index and the annual Producer Consumer Price Index inflation rates.

2) Presently, the Act lists several "aggravating factors", which increase the statutory penalties from $500 to $1500. Even if multiple aggravating factors are present, the penalty does not increase beyond the penalty for a single aggravating factor,

Instead, the penalties should have a 1991_$ 1000.00 increment for each aggravating factor, so that, for example, if three aggravating factors are present, the statutory damages should be 1991_$ 3500.00 In particular, each request by the callee never to be called again should also be regarded as a separate aggravation, so in the case of a caller having been told by the callee 100 times never to call again, the damages should be 1991_$ 100,500.00.

3) Robo-calls are especially disruptive. The statutory damage-increment for robo-calls should be 1991_$ 3000.00 instead of 1991_$ 1000.00. Moreover, the callee should be reimbursed for attorney and court costs.

4) Spoofed-number calls are inherently deceptive, and should be considered deliberately fraudulent. The statutory damage-increment for spoofed-number calls should be 1991_$ 5000.00. Moreover, the callee should be reimbursed for attorney and court costs.

Calls that spoof either medical-provider numbers or government numbers should have penalties as severe as those for impersonating a police officer; moreover, statutory civil damages should be at least 1991_$ 15000.00 per offense.

5) As noted above, currently telecommunications vendors have no incentive to cooperate with callees, making spoofed-number calls almost impossible to track and penalize. Instead, they need an incentive. Telecommunications vendors should be reimbursed by the court at a rate of 3x their costs, for helping to establish the identities of guilty parties.

6) When foreign call centers are found responsible for violating the Act, they should be cut off from telecommunications-contact with the US, by whatever means (diplomatic or otherwise) are necessary.

GitHub Copilot copyright case narrowed but not neutered

Judge ignored the law: Derivative works

From the Copyright Act (17 USC section 101):

A “derivative work” is a work based upon one or more preexisting works, such as a translation, musical arrangement, dramatization, fictionalization, motion picture version, sound recording, art reproduction, abridgment, condensation, or any other form in which a work may be recast, transformed, or adapted. A work consisting of editorial revisions, annotations, elaborations, or other modifications which, as a whole, represent an original work of authorship, is a “derivative work”.

The "Judge Tigar in his order agreed with the defendant companies' argument that the alleged DMCA violations can only occur when the copied works are identical" is completely contrary to that section of the law.

The "The judge also tossed the plaintiffs' claims under Sections 1202(b)(1) and 1202(b)(3) of the US Digital Millennium Copyright Act" is also in complete defiance of the Law.

Judge Tigar should be impeached.

Tax consequences and e-books

You can't donate e-books for a tax deduction. So the sticker-price is "real."

But for all those physical books you don't want to re-read: donate them and get the tax deduction. The effective price of the books then is about 65% of the sticker-price.

Whenever e-book prices are more than 65% of the physical-book prices, it's a rip-off!

Spoofed numbers

Spoofing phone numbers of government agencies and health-care providers should be a felony -- just as much as impersonating a policeman is. And civil damages should be at least $25,000 per violating call.

The present civil penalties scheme under the US Do Not Call Act is grossly inadequate (the civil penalty is $500 if no aggregating factors are present, $1500 if any or all aggravating factors are present): the whole scheme needs to be adjusted for inflation since 1990, and then additional penalties for multiple aggravating factors for a call should be additive. Use of any spoofed number should be a severe aggravation -- say $5,000 -- with $25,000 for government/health-provider spoofing.

£42k for a top-class software engineer? It's no wonder uni research teams can't recruit

...capable... NOT!

"...scientists whose main roles lay elsewhere. Although they were capable..."

NOT.

From 35 years experience as a PH.D. mathematician and software engineer for environmental modeling, it is my experience that most of these are not only not capable, they are not willing to accept the possibility that they don't know everything. Frequently they are actually hostile to both software engineers and mathematicians.

Among meteorologists, there seems to be an institutional insistence on codes written for the limitations of mid-1980's vector machines and their compilers. And the "sensitivity" version of US EPA's air quality model is rife with errors caused by not considering numerical overflows and underflows correctly...

Write C++ in any language

There's an old joke that some programmers can write Fortran in any language.

The sad fact is that in some parts of the environmental modeling community, the fashion is to write just this sort of incomprehensible C++ in Fortran!

[Fortran, btw, has actually evolved into a very nice language -- much safer than C/C++. OTOH, it is still possible to write much of the stuff the joke complained about using "legacy" compatibility features in Fortran. FWIW.]

Moore's Law is deader than corduroy bell bottoms. But with a bit of smart coding it's not the end of the road

Performance limits

And because of parallel overhead (for example), that inefficiency sets limits on best turnaround time. When you plot performance vs number of processors, you normally get a U-shaped curve: at first, adding processors cuts your turnaround time, but eventually the parallel overhead kicks in enough that adding more processors adds to your turnaround time. 64 processors may well be slower than 32 in that instance.

The way to fix it is better algorithms and better coding, to push the whole curve downward toward the X-axis.

Twenty years ago or so, I reviewed a paper on someone's parallelization of an atmospheric-chemistry model. Their best performance was happening at the 16-processor level. But. A different and equivalent model I know achieved better performance than that one on just 2 processors -- and scaled better, so that its performance-curve was best at 32 processors. If your model is too inefficient to begin with, it doesn't matter how many processors you throw at it, you are limited by that initial inefficiency.

If only...

Except that many of these supercomputing applications are written to suit the hardware-behavior and compiler-limitations of 1980's vintage vector machines. Unnecessarily.

American ISPs fined $75,000 for fuzzing airport's weather radar by stealing spectrum

Re: Sensible suggestion

Then the alternative is to create more-reasonable causes for private action.

Currently, the law calls for $500/call civil damages (with $1500 for calls after a request to cease). Court costs are going to be a lot more than that, so it's a losing proposition for the call-receiver.

As a suggestion, define an "aggravated violation" of the Do Not Call act as either (a) robocall; or (b) call that uses a spoofed or obfuscated phone number, and let the penalties be:

*) $5000/call

*) legal and court costs

*) triple reimbursement for teleco costs in helping identify the offender

As the previous poster noted, you need to encourage the telecos to *want* to help.

Also, larger penalties with costs included would encourage the legal profession to want to help (better than than ambulance-chasing :-)

The cloud is great for HPC: Discuss

On those virtualization overheads

Consider how AWS behaves relative to an HPC application compiled with "-xAVX" on a SandyBridge or later AWS node (this causes the compiler to use the "AVX" vector instruction set in building the executable program). Here are some notes from my own experience:

When running "on the bare metal", well-written CFD applications typically see an 80% or better performance boost. The WRF weather model only sees about a 30% improvement with "-xAVX", showing that the design and/or coding is rather sloppy.

However, on AWS, WRF compiled with or without "-xAVX" causes virtually identical performance (within 2%) -- performance that is significantly worse than the "bare metal" performance, by the way. This indicates that the virtualization is killing the potential improvement from the more powerful processor and its (more-powerful) instruction set.

FWIW.

Your wget is broken and should DIE, dev tells Microsoft

Re: If only ...

Back many years ago, at their press conference where they introduced Windows NT, the Microsof marketroids doing the presentation claimed, "It complies with POSIX. In particular, it has the Korn shell, 'ksh'."

When one of the audience claimed, "No, you've got ksh semantics wrong", the marketroid replied, "No I assure you that it is correct."

"No, it isn't."

"Sir, I assure that our experts have looked at it, and..."

Interruption from another member of the audience, "Look, asshole -- that's David Korn himself!"

So this broken wget is typical Microsoft.

Linus Torvalds fires off angry 'compiler-masturbation' rant

sizeof --> size_t

Because "sizeof" gives a "size_t", the entirety of "hlen + sizeof(struct frag_hdr) + 8" should also be "size_t" and the comparison should be of "size_t".

Assuming a 32-bit system, you're in trouble with networking code for which this overflows.

And if it does, then (it's unsigned, remember), the overflow will be to a small value

and the test will fail for that reason.

If it's a 64-bit system and there is any danger of trouble, your network has long since gone past what it can deal with. And you're requiring far larger messages than either the OS or any conceivable hardware (for at least the next decade) can deal with.

Re: Line length - actually, 60-72

And I REALLY HATE web-presentation that forces lines longer than 120: their stuff is TOTALLY unreadable. (Some of IBM's documentation fails this way; they should know better ;-( )

Amazon's new EC2 compute instances run on SECRET INTEL CHIPS

VM interference with AVX2?

Note to Crazy Operations Guy: the Intel compilers already support AVX2.

However. I have experience running the WRF meteorology model on the previous-edition SandyBridge cores, and found that the performance increment from using the SandyBridge AVX instruction set (as opposed to the Nehalem SSE4.2) was negligible. This is as opposed to "real" hardware, where AVX gives WRF a 30% boos over SSE4.2 on SandyBridge, and where it gives a 70% boost to well-coded computational fluid dynamics apps. Given the Amazon VM environment, I still have the question: does Haswell-EP help _in_this_VM_environment_ ??

Copyright Issues

Let's look at what the Berne Copyright treaty says: it's a copyright work as soon as it is "fixed in a medium", i.e., as soon as it's recorded. And unless it is a "work for hire" or the subject of an explicit, specific written copyright assignment (which fails, unless there is such an assingment naming each specific trip), then the copyright belongs to the performer -- i.e., the driver. In the US, at least, there is precedent for seizing all the computers of the infringer for investigation :-)

Note that the Berne Treaty has long been implemented by all of Europe, North America, and most of Asia...

Apple vs Amazon in ereader format smackdown

taxes and paper-based books

With my paper based books, I go through my collection every year and donate most of them to charity for a tax write-off -- something I can't do with e-books. This benefits the public at large, not just the publisher. And the write-off is typically worth as much as Amazon's e-book price-discount. [I don't "do" Apple.]

So why go for DRM that locks things into "me-only"?

Freedom means allowing secondary markets. Preventing secondary markets, for the benefit of politically connected corporations, is within the technical definition of "fascism."

How to counter premature optimisation

But get data structures and algorithms right

Far too many codes are developed according to the developer's first idea:

he/she blindly goes ahead with the first idea that probably works.

They don't stop to think about what data structures are appropriate, nor what algorithms.

For modern (deeply pipelined) processors, there are two primary performance inhibitors: dependencies and memory access.

Particularly, deeply nested logic or deeply linked data structures have big costs, as do huge data structures.

I just finished re-writing an environmental-simulation code, which (for a primary operational case) went from a working-set

size of 3.4 GB to 640 MB, and a run-time of 130 CPU-minutes/simulation-day to 7 CPU-minutes/simulation-day. The primary optimization was the elimination of several huge scratch-arrays (with their associated memory traffic), and the replacement of "dumb" run-time searches with setup-time sparse matrix construction. *Not* rocket science.

In another example fifteen years ago, went from a more extreme 12 Cray-hours to 163 SPARC2-seconds, replacing dumb array

searches with sparse matrix arithmetic...

And in both these cases, the results are simpler, clearer, and more maintainable than the originals.

"Think (alternatives for data structures and algorithms) before you code" should be Principle Zero.

The ODF debate: A real world view

Documents held hostage

*BELIEVE* that Microsoft *will* hold your documents hostage. Two weeks ago, while out of town for the week, my wife found it happening to her: she had planned to use "remote desktop" software to continue with urgent work that needed to be done. But M$ so-called Windows Genuine Advantage suddenly kicked in and locked her out of her own desk-top machine (yet another "false positive"). And she was 1000 miles away from the installation disks M$ demands to know about for re-activation (not mentioning the hours on the phone it takes to convince them of anything). She was *hosed*. Partly because of an "urgent uppgrade" to which she never consented.

Microsoft's OpenXML is so complex a format -- and so dependent upon the (Microsoft) proprietary sub-formats for "legacy" document BLOBs (binary large-objects) it contains that you can be quite certain *no*one* except Microsoft will be able to use it. So OpenXML is open in name only.

Her lost time for that one incident (she is an attorney; her hourly rate is a bit more than mine!) crosses the US$ 5000 threshold for the US Computer Fraud and Abuse Act: as far as I am concerned, Microsoft are a bunch of felons who have bought off the Bush administration via their agent Abrahamoff. And you should *never* trust your documents to them.
