Drunk_Engineer··on German court sends VW execs to prison over Dieselgate scandal
The headline says "execs" but I don't see any Board members getting prison terms. Martin Winterkorn, the CEO, has basically escaped prosecution altogether.
Drunk_Engineer··on California sent residents' personal health data to LinkedIn
However, it may violate the state's Electronic Communication Privacy Act.

Drunk_Engineer··on Ford's electric Mach-E outsold the gas-powered Mustang in 2024
Ok, but which earns more profit? Ford's EV division overall loses $5+ billion per year.

Drunk_Engineer··on U.S. appeals court strikes down FCC's net neutrality rules
Mobile broadband uses public airwaves, which is entirely FCC jurisdiction.

Drunk_Engineer··on How AlphaChip transformed computer chip design
From what I saw in the rebuttal papers, the Google cost-function is wirelength based. You can still get good TNS from that if your timing is very simplistic -- or if you choose your benchmark carefully.
Drunk_Engineer··on How AlphaChip transformed computer chip design
Yes in combination. Customers generally buy these tools as a package deal. If the placer/floorplanner blows everything else out of the water, then a CAD vendor can upsell a lot of related tools.
Drunk_Engineer··on How AlphaChip transformed computer chip design
Oh man, if only it were that simple. A floorplanner has to guestimate what the P&R tools are going to do with the initial layout. That can be very hard to predict -- even if the floorplanner and P&R tool are from the same vendor.
Drunk_Engineer··on How AlphaChip transformed computer chip design
I have not read the latest paper, but their previous work was really unclear about metrics being used. Researchers trying to replicate results had a hard time getting reliable details/benchmarks out of Google. Also, my recollection is that Google did not even compute timing, just wirelength and congestion; i.e. extremely primitive metrics.

Floorplanning/placement/synthesis is a billion dollar industry, so if their approach were really revolutionary they would be selling the technology, not wasting their time writing blog posts about it.

Drunk_Engineer··on Cobb Tuning Hit with $2.9M Fine over Emissions Defeat Devices
Or...just go through their customer list and revoke the registration of any vehicles that were modified. Customers can then pay for having vehicle inspected at the DMV.
Drunk_Engineer··on Edinburgh, Scotland makes it illegal to advertise SUVs
Automakers spend anywhere from $20-$30 BILLION annually on advertising, largely on TV and internet. Good luck to Edinburgh trying to shut off that firehose.
Drunk_Engineer··on The binding of cosmological structures by massless topological defects
IANAA, but this says we don't have to rely on with the notion of dark matter at all.

The paper proposes a special type of singularity that apparently has all the properties of galactic rotation and bending light normally associated with dark matter.

Drunk_Engineer··on A vintage 1903 espresso machine at a Village cafe (2012)
In 1927, the first espresso machine was brought to America. The huge machine is still on display at the Caffe Reggio in NYC.
Drunk_Engineer··on Peter Jackson on how Tolkien stopped a Beatles LOTR film (2021)
Kubrick did Spartacus (I think you meant to say). Kingdom of Heaven might be a better example from Ridley Scott.
Drunk_Engineer··on Peter Jackson on how Tolkien stopped a Beatles LOTR film (2021)
They wanted Kubrick to direct, so it could have been a serious effort (Kubrick declined).
Drunk_Engineer··on Boeing faces new US investigation into 'missed' 787 inspections
That was 4 years ago, and the case has not gone to trial.
Drunk_Engineer··on Bay Area workers charged for building secret apartments inside train stations
While these guys were taking a few grand for a kitchenette, Caltrain top management gave away $150 MILLION to some well-connected friends for the failed CBOSS signal system project. CBOSS was an complete sham, but of course nobody will go to jail for that.
Drunk_Engineer··on FCC chair rejects call to impose Universal Service fees on broadband
In California, money from traffic fines does not get paid back to law enforcement agencies. In fact, local city government has to pay for traffic enforcement, but gets no revenue from the fines because it all goes to the state.
Drunk_Engineer··on US rail safety legislation stalled one year after East Palestine Ohio disaster
This "safety" legislation is mainly about requiring 2-man crews on trains. The unions are of course very much in favor, but it would do nothing to prevent derailments like what happened at E. Palestine.
Drunk_Engineer··on Maui residents who disobeyed barricades survived fires
All it takes is one fallen power line or tree to turn that stroad into a giant parking lot of death. Cutting back brush and undergrounding power lines is much more cost-effective than building stroads up into the hillsides.
Drunk_Engineer··on Marion County atty withdraws search warrant against Kansas paper, returns items
It was rather bizarre to say the search warrant was "withdrawn". That is not something which can be undone once police have taken possession of some items.
Drunk_Engineer··on Want fewer car accidents? Remove traffic signals and road signs (2017)
This factor of 5 difference in 3rd world countries might actually be explained by Smeed's Curve:

"In 1947 Ruben Smeed, the founding father of transport studies in Britain, discovered an intriguing statistical relationship [for 20 countries] between the number of cars per person, and the road accident fatality rate per car. The data revealed that as numbers of cars increased, the death rate per car plummeted.

"The Smeed Curve might be considered a societal learning curve. As one encounters more cars people, literally, learn how to live with them. Another part of the explanation might be found in contemplation of other societal changes that accompany rising car ownership. Car ownership correlates highly with measures of affluence. Death rates per car decrease as affluence increases.

"When cars are few in number most fatalities are vulnerable road users (pedestrians, cyclists and motorcyclists). As vehicle numbers increase the vulnerable retreat."

Drunk_Engineer··on Matrix multiplication using only addition
As a chip designer, I'm dubious of this claim:

"The advantage of performing matrix multiplication using only addition for arithmetic is that it then becomes feasible to build special- purpose chips with no multiplier circuits. Such chips will take up less space per on-chip processor."

Perhaps that is true in a toy design, but in real-world chips the multiplier uses only a very tiny fraction of chip real-estate. And even if the matrix-multiply can be eliminated, there are other uses for multiply operations.

I once attended a chip design conference where NVidia discussed its latest GPU. In one of the slides showing block layout, the designers pointed out how barely any silicon was being used for actual floating operations -- the vast majority was for pipelining and moving bits around.

Drunk_Engineer··on Supreme Court Opinion on Student Loan Forgiveness [pdf]
So if MOHELA were actually harmed -- shouldn't they be the plaintiff in the lawsuit?
Drunk_Engineer··on Supreme Court Opinion on Student Loan Forgiveness [pdf]
"In Supreme Court oral arguments, it was revealed that MOHELA hasn’t made a contribution to that fund in 15 years...Furthermore, an analysis from the Roosevelt Institute and the Debt Collective shows that MOHELA stands to gain revenue if debt cancellation goes forward."

Drunk_Engineer··on Supreme Court Opinion on Student Loan Forgiveness [pdf]
Actually, MOHELA specifically said it was not harmed by the loan forgiveness and wanted nothing to do with the case. This is why many are baffled by the Court's decision to ignore Standing.
Drunk_Engineer··on The Supreme Court rejects Biden’s plan to wipe away $400B in student loans
This was a rather bizarre decision for the way Justices sidestepped the crucial issue of "Standing". There were 6 states that brought the case, and none of them would have suffered any harm from the loan forgiveness.

Drunk_Engineer··on Trapped Under Trucks
Side underride guards weigh as little as 150 lbs, and have been successfully tested at 40mph speeds.
Drunk_Engineer··on Trapped Under Trucks
Closed sideguards actually improve fuel economy due to reduced air drag.
