Comment Re:USB fishing (Score 1) 40

How about making ports like the infamous "USB Kill Stick" but in reverse? Any unauthorized device connected to the port would get fried.
The attacker would probably not find out what happened until afterwards when they try to get the data from the attacking device.

But yeah, if we knew what kind of attack they used to gain access one could provide another set of files: a honey pot, or just innocuous data.

Comment Nolan's movies. sure. (Score 1) 360

Christopher Nolan is IMHO one of the few filmmakers who still makes movies the proper way - with film, in regular old 2D cinemascope and uses the whole image, with good cinematrography. Each movie I have seen of Nolan's has been both a visual treat, an immersion into a very special world and sometimes thought-provoking. They have made me think about the movie experience for days afterwards.

But most of the movies these days are cookie-cutter action/comedy "popcorn" movies, and always with 3D glasses that provide worse image quality than even a regular DVD on a 27" TV.

You already had me, Nolan. But you can't persuade me to go to the theatre to see something else than your own.

Comment Harder to counter Microsoft spying on you (Score 5, Interesting) 239

According to "Barnacules Nerdgasm" on Youtube, who previously worked on Windows at Microsoft, people he know who are still inside have told him that "telemetry" (I.e. spying) will get harder to disable in future updates. Whether all of these will be in this next update or in a future one is hard to say.

He commented to his own video with this:

I've been talking to a few 'insiders' at Microsoft that are also saying that many of the things like App Store and Telemetry are now being hard coded into key services like explorer.exe and critical system services that if stopped will crash the box immediately. The reason for this is obviously to prevent programs like anti-beacon from disabling these services. It's pretty obvious at this point that Microsoft wants the data at any cost and their cover story is bullshit. I'll update you guys when I know more or when the Windows releases are public that contain these changes and we'll do a video on how to create a network bridge between your system and the internet to prevent telemetry from working even with all the services on the box trying to make contact.ï

Comment Sweden is not "on track" to becoming cashless! (Score 1) 366

Sweden is being derailed into becoming a cashless society.

It is a change pushed by banks and related tech companies, so that they can make a little bit more money. Nobody else wants it.

Leading politicians on a national level are not very interested in the issue - spending more time and energy on squabbling between themselves, pointing finger at each other's small mistakes than willing to take on real responsibility themselves.

Comment Re:sunset mode (Score 3, Informative) 118

No, that is a serious thing. Colour temperature of the ambient light around you affects with your day-night cycle. We are made to respond to the sun's light which is colder in the morning (to wake you up) and warmer in the evening (which helps you sleep).
When the primary light source is your computer/device screen then that is what affects you the most.

This has been covered several times before here on Slashdot. Some that are easy to find.

However, I think that the change should not be abrupt but be gradual to better cohere with the sun's natural cycle. But I suspect that they chose to make it a special mode so as not to interfere with colour accuracy during work time.

Myself, I wish that I could also get LED bulbs that changed colour temperature gradually depending on the time of day, and that they wouldn't be expensive and hackable (Like Phillips ... ). I live in the North where some winter days are darker than summer nights, and thus artificial light is important all day.

Comment Paris-London is a stupid choice (Score 1) 90

There is already an electric train between Paris and London that takes between 2:16 and 3 hours + 30 min checkin time: The Eurostar through the channel tunnel.

As a rule of thumb, any train journey faster than five hours is faster from city-centre to city-centre than getting on a plane.
That is because there is so much time overhead before and after the actual plane ride - most of all, the journey to and from the airports.
The only benefit for taking this plane would be if you would change to another plane at the airport or if your actual destination is not in the city proper but closer to the airport.

Comment Re:Not the point (Score 1) 213

Not really. Audio quality peaked about twenty years ago.
A nth-generation screening copy of a film has practically the same resolution as digital 2K (about 1080p), and 2K is still the norm among projectors out there.

And during these years, theatres have been "upgraded" to show stereoscopic "3D", often with the "Real D" system.
However, with "Real D" you get less than half the light intensity of a 2D movie and worse: cross-talk between the left and right eyes. And then there are the artefacts that are inherent in stereoscopic 3D: fast action becomes a blur, gimmicky 3D effects in movies (yes, in 2017 we still have those) and also cinematography has to be simpler to work in 3D - which diminishes the art. And that is if you are one of the lucky 80% that are able to watch stereoscopic images, and watch them without getting a headache.
Therefore, You can not say that "Real D" has good image quality.

Then most showings are in 3D, so that you would have to pay more for worse image quality to see the movie. The only alternative for 2D is often a small shoebox-sized theatre some way out of town that does not have good audio.

Also, Real D is not compatible with the more brighter types of screens out there because of the need to avoid light scattering, so screens have had to be downgraded.
And this means that when 2D movies are screened, they are screened on these same duller screens that are inferior to the ones that were used twenty years ago.

Yes, in the recent years Laser-IMAX has emerged, and that one is properly bright. There is however the so-called "Lie-Max" that is labeled IMAX but is basically what I have talked about above and you should not confuse the two.
Laser-IMAX has the only 3D tech out there in real theatres that has decent image quality ... but the screen is closer to the audience than in regular threatres, so you have to make sure to get a seat right in the middle of the theatre or else you would have to watch it from a skewed angle. The screen's aspect ratio is also smaller, which means that some movies are shown zoomed in.
That is if there is a Laser-IMAX theatre in your area at all, and you think you can spend two-three times the price of a normal ticket...

Comment I could write a book (Score 1) 300

I could write a book about one boss I have had, because there are so many crazy stories about him. And yes, I have seriously considered doing that.

He was the designer of the company's product, he was micromanaging everything so that nothing significant happened unless he himself was involved, he was a compulsive liar ... and he was an alcoholic.
He spent most of his days at an outdoor table at the local bar just outside the office, where he held "meetings". He even had people hired mostly to be his entourage, so that he would have some company to drink with and tell stories to.
At lunchtime, you had to be very careful not to walk too close to the bar (which was almost just outside the office door) or you would be called over ... to spend the rest of the day there and forced to listen to his stories.

Eventually, he was fired after having crashed a meeting with a client that had led us to lose our contract with them. He had been drunk and told a lofty tale which included how he had supposedly killed a guy ...
The company had of course consisted of mostly air ... so when he left, the company was downsized from a multinational company to a handful of people and it changed focus.
Weirdly... the company survived thanks to the devotion of its programmers, it rose and fell under yet another idiot after another, but that is another story.

Comment Crippled Ryzen 7 (Score 4, Informative) 173

Unfortunately, it seem as if these 6-core and 4-core Ryzen 5 CPUs are only going to be eight-core Ryzen 7 CPUs with cores disabled in both compute-complexes.

The R5 1600X and 1600 are going to have one core disabled per compute-complex (CCX): 3+3. This was expected.
However, surprisingly, AMD has told Anandtech and Ars Technica that the R5 1500X and likely also the R5 1400 are going to have two cores disabled per CCX: giving it a 2+2 config.

When clock and IPC have been taken into account, Ryzen's biggest performance bottleneck compared to Intel has been shown to be when threads on different CCX'es are accessing the same memory. Each CCX has its own L3 cache and there is an interconnect between the CCX'es L3 caches which while being slower than a single shared L3 cache is somewhat faster than going to main memory ... but the L3 caches are only victim caches to each core's L2 cache - and therefore not necessarily caching the entire working set.

This means that the 1500X and 1400 are going to be slower on many workloads than on a hypothetical Zen CPU with one single four-core CCX.

It is believed that this bottleneck is the reason behind relatively low Ryzen 1800X/1700X/1700 scores in many games - compared to Intel (even when clock speed and IPC have been taken into account).
(Curious enough, this is also a known issue among programmers for the XBox One and PS4 - both having AMD CPUs with a similar setup, but apparently it didn't really occur to game programmers that AMD would have a go at retaking the desktop?)


Ask Slashdot: How Do You Make Novice Programmers More Professional? 347

Slashdot reader peetm describes himself as a software engineer, programmer, lecturer, and old man. But how can he teach the next generation how to code more professionally? I have to put together a three-hour (maximum) workshop for novice programmers -- people with mostly no formal training and who are probably flying by the seat of their pants (and quite possibly dangerous in doing so). I want to encourage them to think more as a professional developer would. Ideally, I want to give them some sort of practicals to do to articulate and demonstrate this, rather than just "present" stuff on best practices... If you were putting this together, what would you say and include?
This raises the question of not only what you'd teach -- whether it's variable naming, modular programming, test-driven development, or the importance of commenting -- but also how you'd teach it. So leave your best answers in the comments. How do you make novice programmers more professional?
