Before I left HPE post Cray acquisition, some of the folks in the consulting/"cloud" division insisted that to use their tooling, we had to insert a windows machine into clusterstor, that mounted lustre, so that they could ru

We had ours mid 30s. I also founded a company and ran it for the first 15 years of her life. That is stressful. To put it mildly. This said, having a kid is the toughest and most rewarding job you will ever have. If you don't like k

Precisely. Indexing makes sense in a context, and it is trivial in general to switch. This said, telling people that the first element they want is the "0th", is completely unnatural.

Really its only an issue to some programmers, who prefer specific languages. When you have to deal with a wide range of languages, stuff like this is small potatoes, compared to, say, indentation based structure. The latter can result in t

1-based indexing makes sense to computational scientists (target audience). Fortran, Matlab, etc. make very good use of that. Moreover, you can change to zero based if you wish. So this "very big elephant" is, in reality, a noth

This is one of the nicer aspects of Julia. It starts out being a great language to work in. Its easy to implement algorithms that are generally difficult in other languages. Its important to remember that most of the python ecosystem, isn

I'm not the only one at my co that has experienced it BSODing. Windows generally BSODs on work machine at least once a week. Windows 10 patched monthly, locked down as hard as a machine can be under Windows. 30 plus years of Windows

Not a lawyer. Zoom client on Linux works and is IMO more reliable (e.g. doesn't BSOD me) than windows, about the same reliability on Mac. Teams is unreliable on every platform (having used it for years on Linux, Mac, Win). Would reco

Very likely, each fusion plant (if they ever exist) would require, ironically, a fission plant next door to provide the power required for the magnets. The magnets, and wiring won't be cheap. The power delivery and control won't

Probably not what you want to hear, but ... I'd recommend migrating all your important data and code out of that system ASAP. Make (at longest) monthly backups of your code/data, and keep them locally. I know, this can be impract

I've had trouble with all the services (MSFT and others) sending texts. I blame Verizon more than the big tech folks though, as their SMS is remarkably unreliable. That said, my first pass through MSFT 2FA hell left me with the indeli

I am biased, as I am the father of a wonderful (adult) child. Some thoughts. 1) Being a parent was the absolutely best thing that I've ever done and experienced. Nothing IMO, can compare to this. 2) Climate change was not (ever) a con

Huh ... the example I used (Tay-Sachs) is an example of this. So I stand corrected. Thank you! Thank god that the tech to sequence genomes was not available in the 1930s/1940s. Imagine what evil could be done with so much informatio

I'd say "both". 1st, you need to help them get the RCA on why this question, and what context (that isn't often brought up). Its often that framing the question in context elucidates the actual problem they are working

Equal pay for "equal work". Two people have the same job. One is 2x as productive as the other. But they would be paid the same, due to a drive for pay equality. Such concepts punish high achievers.

The initial value could be measured this way. Market price discovery. Without external influences (collusion, etc.) the market will generally define price bands. The stock market is an example of this (to a degree). The job market is al

The flip side to this, is that workers who bake 1 pie per hour will demand the same pay as those who bake 10 per hour. Lest their "rights to equal pay" be under threat. Put another way, it will be very ... very difficult to rewar

I'd suggest looking at the Invariant mass page. What you are talking about isn't rest mass of a photon, rather the center of mass invariant mass[1]. This arises from the equivalence principle, the relation between mass and energ

by hpcjoe 5y ago
Photons are not generally thought to have a rest mass, unless something has changed in the last 25 years or so. The conversion of energy into 2x electron masses (positron + electron). So the photon pair needs at least 2 x 911 MeV of energ

Agreed. I tend to use syntactic sugar like use constant true => (1==1); use constant false=> (1==0); in many of my codes. It lets me use them as barewords, and makes the logic it appears in, saner. But this is a style/

FWIW: I am using it as a general purpose language at the intersection of large data sets, analytics, and related bits. At a prop shop. YMMV, but I find it is fantastic in this use case. And I don't have to worry about semantic space

My biggest complaint is static compilation. There are things you can do with PackageCompiler, but they don't work for some of the code I write. This makes deployment of artefacts harder than it needs to be. Most of the infrastructure
