Comment Re:Why 64bit is faster than 32bit? (Score 1) 92

Integer types in C are the same size on 32-bit and 64-bit Windows. On most 64-bit Unix:es and Linux, "long int" are 64 bits as opposed to 32 bits.

The big difference is that pointers are 64 bits instead of 32.
Pointers and 64-bit integers are also 8-byte aligned instead of 4-byte aligned. (at least on Linux they are)
It may not seem much but if you have large arrays of structs with these types, it could add up.

Bitcoin's Value Plummeted Overnight and No One Knows Why (slate.com) 461

Jacob Brogan, writing for Slate: While the Western Hemisphere slept, Bitcoin plummeted. Just after midnight Eastern Time on Friday, the cryptocurrency was valued at a little over $15,000, on the digital currency exchange Coinbase. At that point, it was already well below the $19,783 all-time high it had hit the week before. Over the course of the night, Bitcoin began to decline erratically, occasionally spiking but following a general downward trend. Around 9:22 a.m. Eastern, it hit a temporary floor, valued at a mere $10,400. By that point, it had declined more than $6,000 from its short-term peak the morning before, having lost more than one-third of its value. Bitcoin wasn't the only currency hit by a sharp drop. Tech Crunch's Jon Russell reports that most other prominent cryptocurrencies also fell, including Ethereum, Litecoin, and Bitcoin Cash (which is, confusingly, separate from Bitcoin proper). As Russell notes, it's hard to say why this is happening, "in the same way that nobody knows exactly why bitcoin's price has [shot] up from a touch under $1,000 at the start of the year."

Comment Re: No radiation risk (Score 1) 344

Meanwhile, in my small country, brain tumours are on the rise. Cell phones seem to be more popular here than in the US. The cities are more densely populated.

Anyway, I don't think the risk is so much from cell phones themselves.
I would be more concerned for people who are living or working too close to a cell phone tower. In the latter case, it is not just the frequency band that the cell phone is using, when it is being used. That tower is on all the time and could be in 2G, 3G, 4G and 5G all at once and/or long-range high-speed directional microwave links between towers instead of fibre.

That's not how it works.

The electromagnetic waves from mobile phones do not cause the initial mutation that causes a cell to turn into a cancer cell and multiply out of control. That fact has been long established and is not contested here.
What microwaves in the frequency ranges used by cell phones have been shown to do is to promote the growth of existing cancel cells.

Mutations into cancer cells are actually not as uncommon as most people think. All of us have had cancer cells many many times, but what normally happens is that the immune system detects the microtumour and kills it long before it has grown large enough to cause a serious problem.
All of us have been exposed to cosmic radiation, practically all of us have had X-rays a few times in our lives, all of us have inhaled and ingested carcinogenic chemicals from car exhaust, pollution, first- or second-hand tobacco smoke etc. etc.

Carcinogens are all around us, but you don't get cancer that easily.
Cancer risk is about probabilities: many different factors are at play.
And radio frequencies in the part of the microwave spectrum, at frequencies and levels that mobile phones use - have been proven in several studies (I have heard of two beside the California study) to be one of those factors.

I agree. Mara Jade even had an official model that used to show up at sci-fi conventions, as did many of the book authors.
The problem with the EU is that were quite a few things in the EU that was of questionable quality, and many things even contradicted each other or contradicted facts in the prequel movies.

At a convention in summer of 2013, Lucasfilm announced that they were going to sort the EU out. They were going to pick the best bits and put the main storyline into a new consistent canon and scrap the rest. (I was there in person and heard it directly from Leland Chee's and Pablo Hidalgo's lips)
In early 2014, however ... Lucasfilm announced that they were instead going to scrap it all and relabel it as "Legends". They still print and sell new copies of those books though - with a new "Legends" label on the cover.

Dave Filoni (showrunner of Clone Wars and Rebels) did pick a lot out from the old EU to use in his series. Grand Admiral Thrawn in Rebels is one of those. The Nightsisters of Dathomir is from the EU also.
Darth Maul's comeback with robotic legs is not even from the EU, but from an alternate universe story where he shows up on Tatooine, wanting revenge on Obi-Wan for having been cut in half on Naboo some thirty years earlier ...

The two main complains I have seen about The Last Jedi have been:

* It contained too much comedy. It reminded them too much of a Saturday morning cartoon than a Star Wars flick.
That's perfectly fine for a movie -- if that is the general tone of the franchise but this is the eight movie in a series and that would in many older viewers' eyes require it to follow an established format or it would get close to jumping the shark.
For the casual viewer, however, and for most reviewers -- who don't view the movie more deeply in context -- this does not matter at all.

* At the end, not much has been accomplished. The state of the universe is pretty much as it was when the movie started.
I don't agree with that though.

* It is too long and could have been shortened. This movie is two and a half hours where as every other Star Wars has been around two hours.

Comment Re:Facebook is not and never was innovation. (Score 2) 268

Usenet in its prime was more or less an elitist forum - for academics at universities and large corporations. The less fortunate computer nerds used to dial up BBS systems, which had organised its own FidoNet for inter-BBS communication.

Usenet was not succeeded by Facebook. Facebook was made for the less tech-savvy.
When Usenet became too spammy, interest groups instead went back to the BBS model, but on the web: specialised forums that they themselves had control over, often running PHPBB ... or even SlashCode.

Comment Zircon (Score 2) 54

BTW, the microkernel at the bottom of Fuchsia has changed name from Magenta to Zircon.
Maybe because there's a Magenta Linux... I dunno.

Zircon has security based on capabilities (which it calls "handles", rightly so IMHO) for pretty much everything. This could support sandboxing of new sub-processes that you own, but it lacks revocation of rights from running processes that would be used as services -- which I find to be a serious omission.
IPC is very much like Unix domain sockets: with streams and queued asynchronous message passing... which means that it is never going to be faster than Mach ... and Linux is demonstrably faster than Mach. seL4 would have been a better foundation IMHO.

Comment Re:At maximum volume (Score 1) 104

It's actually the opposite. Cell phone speakers these days are so small that overdriving them is considered normal. The DSP in the audio codec/amplifier is supposed to compensate enough to avoid artefacts and to avoid damaging the speaker but it is walking a tight line.
I was told this by engineers at Cirrus Logic, which makes audio chips for Apple and other cell phone manufacturers.
