From what I recall reading about this in the academic literature, the primary concern here is that speculative operations on the alternate paths consume power just like any other operation.

You are overgeneralizing. Being front-end bound is true for some code but not for others. We see our gotchas typically in terms of not being able to issue instructions due to data dependencies and filling up the RS with things that can&#x27

This is spot on. We use a lot of intrinsics, as we want to get at some of the underlying features of the architecture, but we almost never write asm. It's becomes obsolete almost immediately and is often far worse than the compiler&#x2

If I remember Brooks correctly, second system syndrome does not refer to all successor systems, and frequently complex/over-built systems spawn elegant ones in turn (oversimplifying a bit, but MULTICS -> UNIX springs to mind). I s

Hmmn. I think there's a fundamental advantage in any rewrite that's allowed to drop functionality - even a C++ to C++ rewrite. It's not just the language. It's the fact that (a) you already have an instantiation of the

There is a fundamental disconnect of reasoning here. What we are expected to believe is that these people at their "big, name-brand companies" are carrying on an elaborate hoax on their employers and their inability to do blank pa

This looks fascinating - and "the real deal" (not crackpottery) but I'm hesitant about a number of items. It seems like quite a reach to pick a 'latest and greatest' IA processor (why is this $885? Because it can

Absolutely true. Note that micro-fusion can allow you to push the number of uops retired per cycle to 5-6 (SNB would be 3 ALU, 2 loads, Haswell could be 4 ALU, 2 loads), as the issue/retire rates are on the fused domain. It's a fa

This is an illustration of Murphy's Law, almost perfectly: "If there's more than one way to do a job, and one of those ways will result in disaster, then he will do it that way." Defensive design would be to make sure, a

First, you are responding to a point the original poster didn't make. He didn't claim that he wanted to shut discussion down to "officially credentialed experts". He claimed that people involved were "unqualified to

Correct. The "significantly better", for better or worse, is likely to be "allows you to share content with your friends that you aren't really allowed to by law". This is probably the only single thing that a feder

Do homeless people have a single canonical name that they will use consistently? Is it fair to request that they structure their day around a hashing algorithm that they don't understand? There's an arbitrary kind of "command" oriented aspe

This is a rather disingenuous comment. Maybe they didn't anticipate that a site that rigorously polices (for example) breast-feeding pictures and race hate material wouldn't rigorously police "rape a bitch" image macros. They have discovere

It's a long time back (1023 days, actually), and I can't find a reference to the article itself, but I do believe we had an article about how to take a poo by none other than Zed Shaw. At least I felt moved to comment thusly: https://news.

My first reaction to this story was "if you liked 'slice of pizza', you'll love 'pile of poo'". Good to see someone got there first.

I can't upvote this one enough. There is an astounding insistence among engineers that they should be able to dress like bums, swear in presentations, consume endless junk food and soda on the company dime, not be required to complete profe

This is a good motivation, but it's plunging right into formulas, which is wrong-headed. Even the mean can be completely meaningless without eyeballing a plot of the data. Given that this is aimed at non-statisticians, it's critical that th

I am not sure that the target audience for the app is identically opposed to "lobbying" and "big corporations" for any player. They might feel that there's something particularly repugnant in the goals or ideology of Koch Brothers or Monsan

What makes you think that the end results of the exit will be obvious ahead of the exit? Do you honestly think the acquirer will put this on a contract? There are a lot of gray areas here. There's a continuum between "disgraceful acquihire"

To expand: most of the startups that exit like this don't usually have the alternative of continuing to exist and make money indefinitely. Either they _are_ failing as a business (in which case, the amount of support that they are going to

Wow. I can't tell whether this is a parody of a stupid response to exits, or actually sincere. When I first read it I thought "wow, neat parody of the overly entitled rageout". Now I'm not sure.

I'm not arguing that it's a bad microbenchmark for FP run-time performance. I'm arguing that it's a bad microbenchmark for compile time and code size. I'm not all that familiar with go, but in most systems I've used, if you write a really t

Erm, this was something I was picturing my (not abused, in case it needs to be stated) younger son asking him upon seeing this, so I'm not sure what your point might be in connection to what I wrote.

Why would anyone care about relative code size or compile time for a program this small? This is obviously a "cost of entry" issue. I have trouble imagining that doubling the code size and complexity of the "mandel" example would double the

No, thank you. I know abused kids are a serious issue, but the vast majority of kids aren't abused, and this is a disturbing ad to show specifically to a kid, especially when the grown-up with them doesn't see it. I'm picturing walking past

This is truly impressive in this day and age. I used to write little games like this on the C64. I do wonder why he is using a tape drive, though. That is taking retrocomputing a step too far. We had a 1541 (IIRC) from day 1 when I first go

If there's a common thread between endless startup failure stories, then it is "we talked to a bunch of people who said they'd spend money on this" and when push came to shove said people didn't actually spend money. We're not failing, bu
