sddfd··on rr: lightweight recording and deterministic debugging
This is a great help, I'm using it most of the time. After I got used to it, plain gdb feels incomplete (mostly because rr allows you to reverse-step and reverse-continue even with watch/breakpoints).
sddfd··on Ask HN: Are slides really necessary during a speech?
The question is too broad to answer with yes or no.

If you can come up with slides that make it easier for your audience to follow you, go for it.

sddfd··on Availability of Java SE 8 updates for personal use in question after 2020
If you are still on the Java boat, it is time to get off.
sddfd··on Ask HN: What are some alternatives to Google maps?
I've used the Apple Maps navigation during the last vacation in Spain (rental car did only support Apple car play), and the navigation desperately needs some love. The worst things are:

- no support for roundabouts: it's really hard to determine where you have to leave, and the spoken hints are not helping. Why not displaying a top view of the intersection/roundabout like other navigation devices do?

- no good support for leaving a highway. If the connection is non-standard the speech commands seem off/hard to understand. Top view again would help.

sddfd··on We’re Measuring the Economy All Wrong
I agree we're measuring things wrong, here are only two examples:

- it's good for a company to sell a ton of crappy cloths that don't last long and the production of which has terrible environmental impact

- it's good to produce a ton of low quality eggs and sell them

sddfd··on Eating in 10-hour window can override disease-causing genetic defects
> our ancestors have been eating the same stuff for millenias so it's probably "right" for my metabolism.

There might be a genetic factor here. The other thing is that the food habits of our ancestors were more thought out than we think. It might be that what they have been eating is not only better because of genetics, but more healthy in general than the terrible foods we can buy everywhere today.

sddfd··on BPG Image format
File a bug :)
sddfd··on BPG Image format
What's the license?
sddfd··on Academic expert says Google and Facebook’s AI researchers aren’t doing science
So, I guess it is hard to get good ML/AI PhD students these days, given what private companies are offering.
sddfd··on China only makes $8 from an iPhone – and that's why Trump's trade war is futile
I don't think it is about the $8.

Previously, China outsourced social and ecological cost of producing iPhones and other technology. That outsourcing is not covered in the price.

Recent political changes in China such as environmental requirements cut the key profit: the outsourcing.

If the US has the choice to either have a factory in China, or have a factory with roughly the same standards at home, the trade-offs are different: you might want the jobs at home then (given that the wages are competitive, which they currently are not).

sddfd··on Can France Create Its Own MIT?
France already has an excellent research system, and the phrase "create its own MIT" is ambiguous at best: This is mainly about branding to increase international visibility of the institutions.
sddfd··on Windows Command-Line: The Evolution of the Windows Command-Line
Please, improve Powershell. The interface is lacking mainly because:

- it's not scrolling fast enough

- it's easily possible to send processes to the background (and job management)

I'd really like to use Powershell on windows but git bash works better.

sddfd··on Markets are efficient if and only if P = NP (2010)
Even if P ist not equal NP, hardness of efficient markets could be in APX2 i.e. computing a solution that is at most twice as bad as the optimal solution is in P.
sddfd··on Jeff Bezos announces Amazon is picking up 'The Expanse'
Great, looking forward!
sddfd··on Intel Xeon processor with FPGA now shipping
This is great! I think that some time in the future, FPGA will be a vital part for data processing.

In theory, an application with a computation-heavy task could program the FPGA to provide part of that task in hardware (think the hot innermost loop body).

What I am worried about is the infrastructure that is needed to make this happen: Is there even support for this in our compilers? What would support look like?

sddfd··on The 9.9 Percent Is the New American Aristocracy
The first graphics clearly shows that the 0.1% increased their wealth disproportionately in the recent years. It does not show this for the 9.9%, so I'm not quite able to follow the conclusion.
sddfd··on Generic Advice for Writing a Thesis
I agree wholeheartedly that writing needs a lot of practice. I feel that in science the craftmenship that is necessarily involved is usually underrated (or taken for granted).

Personally, I find clarity and focus the most important qualities of a thesis. The former requires and displays deep understanding and writing competence, and the latter requires and displays planing and the ability to identify a specific issue (out of all the things one could write about).

Cleverness, however, is not so high on my list of requirements. Many hard problem exists in a space of trade-offs, without a silver bullet solution. Understanding and effectively communicating these trade-offs is probably more useful than a single "clever" solution.

sddfd··on Windows 10 1803 Update Failure
And mostly without any technical user intervention.
sddfd··on Windows 10 1803 Update Failure
Yes, it did on the desktop. I did buy a professional licence for the laptop though (it came with home).
sddfd··on Windows 10 1803 Update Failure
Also having no problems.
sddfd··on Windows 10 1803 Update Failure
I'm running two machines (a recent laptop and an older desktop with Windows 10). I've wiped both drives and did a fresh install of a recent Windows 10 vom USB Stick.

I haven't had any problems updating and even big updates are fast. This is in contrast to a Dell laptop I got for work and which regularily took 45min to update.

If you have problems with your Windows 10, get rid of the crapware that came with your PC and/or do a fresh install from a clean image from MS (not one of the OEM rescue partitions/disks).

I with MS would do something about all the preinstalled crapware, because it has gotten out of hand and is hurting the brand.

sddfd··on Adding BigInts to V8
I agree that the approach "everything is a bigint" plus optimizations where a fixed width int suffices would be nice from the semantic perspective.

However, Javascript has basically the "everything is a floating point number" approach, and bigints would be hard to fit into that (do you want bigfloat as well? do you want to reproduce float arithmetic imprecision, or be precise? Etc.)

However, bigint could internally use just one fixed width number when possible as an optimization - although the current implementation doesn't seem to do this.

sddfd··on Hubble finds first galaxy in the local universe without dark matter
The point is that the galaxy shows that dark matter exists /independently/ (i.e. as its own particles) of normal matter. This is huge.

Up until now, there was a branch of physics that tried to explain dark matter as a phenomenon that is caused by normal matter. This discovery shows that such an approach is unlikely to work.

For all of this, it does not matter /why/ there is no (not a lot) dark matter in that galaxy. Although that is probably the next question physicists are after!

sddfd··on Windows 7 patch for Meltdown enabled arbitrary reads and writes in kernel memory
Are you sure that that particular team inside Microsoft had full six months?

Intel had 6 months.

sddfd··on Banning Netflix, Amazon from Festivals and Awards Is Wrong
So you are saying my recommendations are off?
sddfd··on Banning Netflix, Amazon from Festivals and Awards Is Wrong
Would love to! What would you recommend?
sddfd··on Banning Netflix, Amazon from Festivals and Awards Is Wrong
I don't think so.

Netflix, Amazon, etc. have some great entertainment, but they seem to avoid serious, emotional, social, and political topics.

Instead they keep producing tons of supernatural/superhero series.

That kind of stuff was never particularly popular at Cannes anyway.

I guess what I am saying is that even though they share the medium, they do very different things with it.

sddfd··on When exactly did clowns become scary?
Also: this clowns are scary thing seems to be US exclusive? Please correct me if I am wrong.
sddfd··on A new foundational crisis in mathematics, is it really happening?
One reason why there is no big discussion yet could be that the crisis surfaces only in rigorous type theoretic proof environments such as those provided in the proof assistant Coq and others.

While Coq has been successfully used to formalize mathematical theorems (a term I use here in contrast to computer science theorem), I am pretty sure few mathematicians use Coq or even type theory in their day to day work.

Until that becomes custom, the discussion about HoTT will probably stay in the type theorist community. Interestingly, I also think that only after the crisis is solved we can expect mathematicians to use type theory as foundation for their work.

sddfd··on Why New Zealand is releasing a rabbit-killing virus
Depends on what they expect to happen. This has been done in Australia at least twice with different agents.
