Comment All these "M1 is the best" articles are crap (Score 1, Insightful) 257

Until one of them puts some actual performance per watt numbers I really don't care.
This guy claims it's great that apple provides a chart with no numbers, no labels etc.
"M1 embarrasses all other PCs"
In what way? Care to quantify that in any way?
"M1 is fast and cool while every other CPU is slow and hot" anything to back that up other than the graph you drew in paint?

Comment Link to the talk? (Score 4, Interesting) 236

> talk Linus Torvalds gave at the most recent DebConf conference

Any link to the talk so we can see what this is all about?
Oh, this is about something that happened 6 years ago and not "the most recent DebConf"?
What even is the point of linking to debconf if you don't link to specific talk?
Get your act together.

This is what I've been saying to people. They all seem to think they can just wait out the vaccine. But what evidence is there it will work at all? We've been making vaccines for the flu for decades, and there is no end in sight.
The idea that we can all just sit at home doing nothing for a year or two until there is a vaccine to solve everything seems completely misguided to me.

Do you not have friends and family in other countries, or do they give you business hours for you to call them?
With the current system all I have to know for each country is the time difference. With the new system I would have to remember for each country at what time they start and end their day, and possibly even when they have breakfast lunch and dinner so I can avoid calling at annoying times. Alternatively I would have to make some calculation based on how long after the start of the day those take place.
With the current system I can more or less guess.

> Unfortunately, there are an ample number of embedded C compilers that can't optimize a repeat array reference

Could you name some? I have wondered about this in the past, but all the platforms I have used where I tested it used GCC as the compiler and performed this optimization. I guess maybe automotive or other safety critical industries where the compiler used would be heavily regulated?

Comment Re:Excellent improvement on the implementation (Score 1) 98

I'm not sure it's that much less open to debate. The Linux kernel coding style specifically states not to use them for single line statements unless one of the other branches has multiple lines in which case all branches should have braces.
Personally I do prefer to just have all if statements with braces in line with the Zephyr coding style.

Comment Re:A bit misleading (Score 1) 74

I'm not sure how you got to three. 4 symbols can be represented with 2 bits, so that should be a factor of 2.
Let me know if I'm forgetting some other factor.

Yes, additional base pairs could be used to further improve data density.

On the other part, I almost made the same mistake, but the fact that the bases only appear in pairs doesn't matter, since it's the sequence that encodes the information, and any sequence can contain both pairs in both orientations:
A-T, T-A, C-G, G-C. So it's still base 4. (unless for example A and C always appear on the left, and T and G always on the right, I'm not a DNA expert either, but as far as I know this isn't the case.)
