Lights are always adjustable. On my last car, there was just a screw where you adjusted it one way or the other and it would move the beam up or down. You pull up to a wall some distance away, and adjust the beam so it's at the right l

I have a pixel 2 which is approaching 3 years of age at this point. (2700mAh) I generally finish the day with 50-70% battery life, unless there's some specific reason I'm actively using it all day. (last time was because my flight

It's perfectly usable. (I also have an XPS13 with a 3200x1800 screen) Setting up the infinality font renderer basically negates the downsides of a low resolution screen. TBH, in the future I'll preferentially opt for ~96 DPI when

I bought a new laptop a few months ago that does not do 5GHz. It's a Dell Inspiron 3195, with a Qualcomm Atheros 9565 wireless card. The laptop is still available for purchase. When I purchased it it was on sale for $200. (not sure if

This is, without a doubt, one of the worst UXs I've ever used. This cobbler's children have no shoes. Not because he doesn't care about his children, or can't be bothered after a long day. No; this cobbler simply doesn&#

That Raymarine unit is a secondary piece of equipment, and is there primarily for its transponder capabilities, which the primary radar unit (the AN/BPS-16, which I believe is integrated into the masts) probably doesn't have. The

Yes. The N64 had a unified memory architecture, so the frame buffer was just a region of memory within the unified system RAM that was drawn to. The Z buffer was the same way. (assuming the programmer chose to enable to the Z buffer) It was

It's not so much that CRTs are faster than LCD. It's that old consoles (up until the Sega Saturn, Nintendo 64, Sony Playstation era) didn't draw to frame buffers. They didn't have enough RAM to have a real frame buffer.

Let me start over. My first post was a little terse. Construct a directed bipartite graph. An edge between a number node and a square node indicates that it may be possible for that number to go in that square. The lack of an edge means tha

I think I'm misreading the article. If I'm reading it right, the author is on the right track but didn't make it all the way to the station. The right way to do this is to make this a bipartite maximally connected directed gr

It is utterly bizarre to me that a table lookup is preferable to integer subtraction. The f32 registers are already hooked up to i32 ALUs. A table lookup requires die space, while mine requires none, and the i32 subtraction is already heavi

In the past 3 years or so, there is a native d3d9 implementation in mesa which is used by wine. There's also vkd3d, which is a wine implementation of dx12 on top of vulkan. I don't think the real direct3d binaries are used by defa

In case anyone is wondering why RCP[PS]S and RSQRT[PS]S are specified to give only a relatively small number of digits of accuracy (I think only 7 or 14 bits?) it's because they use the fast inverse square root algorithm in hardware. T

The Battle of Midway was fought in spectacularly deep water, on the order of 17,000-18,000 feet deep. This would make salvaging difficult, if not impossible. Scapa Flow is shallow enough for divers. Once we run out of cheaply salvageable st

It wasn't about one bad vulnerability. Heartbleed was just the last straw. OpenSSL implemented its own memory management system instead of using malloc. It would allocate one pool of memory and then manipulate into that. This meant tha

I agree that this article is short on details. It has a statement about what, but it doesn't mention how, or any manner of why. I do not like it. Specifically regarding the Fibonacci sequence, simple wikipedia has a reasonably non-comp

CPUs have some number of individual units that do different things. You'll have a few ALUs that can do stuff like adding, subtracting, xor, and, etc. You'll have some number of units that do floating point math. You'll have a

The first example won't be solved by adding a higher precision floating point type. Basically, they're summing up a bunch of intermediate calculations. The intermediate calculations are 64 bit floats, and are precise to 17 decimal

IMHO there's no reason for hardware support for floats beyond 64 bit. If 64 bit IEEE-754 floating point numbers do not support your needs, adding more bits will almost certainly not fix the problem. The problem isn't lack of bits,

We have a few models about how black holes might merge. The best model was that a massive binary star might end their lives as a pair of black holes, then spiral down into each other. In this model, there will not be any optical counterpart
