Fixed that for you.

I mean, doing everything over HTTPS does add overhead as you have to spend the cycles on encrypting things, but hey, if it's good enough for Google...

More seriously, make certain at the very least that the login page's form target is https, as are all pages behind the login page. Probably good from a UI standpoint to make the login page itself be served over https so the user sees their browser's "this page is secure" indicator.

It's basically a requirement from a security point of view to have the login page on https - while there isn't any information being transmitted unsecurely, https also ensures the website is unmodified. If you can change the login page, you can redirect the post output (or send it to multiple places) and steal the user / password that way.

Ah, I misspoke -- I didn't mean client side like JavaScript but if you had a thick client where a lot of the work is done on their machine, whether it be C# or Java or some other compiled language.

In the specific case of my company, the server-side C# code passes it in plaintext to the DB (which I think resides on a different network, but I'm honestly not sure) which then encrypts it.

And looking over our encryption procedure I'm a little concerned about its quality but it's been like it is for god-knows how long and it's not going to get changed any time soon either.

A thick client on a really locked-down corporate environment might be OK handling password hashing... until someone get phished. So it's still not a great idea. The client really should use TLS, even on an internal network, but making the DB do it (if it's doing it at all!) is mainly a performance concern.

nielsm posted:

The "blas" package contains the dynamically linked runtime libraries. You need this to run a program that links dynamically against BLAS.
The "blas-devel" package contains the headers required to compile a program against the BLAS library. Only required to compile programs, not to run them.
The "blas-static" package contains libraries for linking statically to, when compiling programs. Only required to compile programs, not to run them.

If you don't know the difference between static and dynamic linking, you should read up on that.
The simplified version is, static linking includes the complete code of the library into the main executable for the program. The static library is only required during build. Dynamic linking only inserts a reference to the library files and function names during build, and the OS loader then builds an in-memory image combining the main binary and the dynamic libraries. The dynamic libraries are required both during build and during runtime.

Jsor posted:

It depends to some degree on the exact build environment. A lot of C or C++ programs/libraries tend to require headers naming the BLAS functions they're linking to and need devel. You could specify or package in your own BLAS headers, of course, when distributing your library's source. This is also kind of how Python's C FFI bindings work, where you have to manually specify the functions signatures in Python, meaning you only need the .dll/.so/.dylib/.a file because you're essentially providing your own header and it's simply searching for the functions in the library at link time (when you call cdll.LoadLibrary generally). Rust's FFI works similarly.

In most cases, anything you find in yum/pacman/apt-get will be linked dynamically, but there are exceptions, hence why the static variant often gets a special listing.

Also, for BLAS specifically probably build OpenBLAS yourself. The one on apt-get tends to have iffy performance.

Depends on the environment I think. I've certainly had programs succeed at building when I had a malformed or misplaced dll/so, but then die at runtime.

Thanks you two. I'm from an aero/mech engineering background now doing a lot of HPC stuff. It's just I've always worked with proprietary/in house codes so there's never been an instance where I didn't need to (re)compile my code so the whole splitting of blas and blas-devel is new to me, though I get it now.

About the compiling OpenBLAS myself:

In general I always heard that this was a bad idea to use your own compiled software vs getting it from a package manager? I mean I have nothing to back this up or know where I even heard this from. It's just always been one of those "things" I've heard. Have I been completely misguided this entire time?

I know that compiling OpenBLAS myself and throwing it into /usr/lib64 or whatever is a bad idea but I thought that kind of extended to "compiling OpenBLAS yourself when it's available in the package manager for your distribution is a bad idea as well because ______." I mean if that's not the case then why should I not compile my own gcc/gfortran with "-O2 -march=native" and then use that to compile my own OpenBLAS, mpich, boost, etc. etc, and throw it all into ~/home/local/ ?

Are we talking optimization in the sense of "here's a function, find the inputs to the function that yield the highest/lowest value"? Or are we talking like "make this function run as fast as possible"? Because the two are very different.

If someone's looking at grad school in OR, it's pretty obviously the first sense.

Optimization is really its own field, and it's not something that's easy to pick up on your own without taking a class. It's not generally taught in any real detail at the undergraduate level because the math requirements are a little too strict, so most programs won't assume that you're coming in with any significant background. As long as you have enough math and a good application otherwise, you'll be fine at the master's level. PhD programs are a different animal entirely.

Yeah more of the former. I guess the big application for optimization applications or processes in OR is helping humans make better decisions with either a known data or a potentially unknown condition or parameter.

Has vast commercial and government applications. Seems to be a growth field as far as back end development niche area.

Is there a general design pattern for building a simple database query interface?

My thinking is start the select with all the fields possible, the build up a WHERE by going through the input fields. Maybe have an array that lists which comparison you are going to use, LIKE (for strings), = (for numbers) < or > (for dates or numbers)

I'm trying to debug a Google Sheets script custom function.

It's kind of infuriating because you can't log from these functions. However, I can call an url. Can anyone think of any web services which can take a message as a query parameter and let me access the messages as a log? I don't even care if it's secure, but if it is, it needs to take an API key as query string as I can't set headers or anything.

Custom functions can't log when used in a spreadsheet (only when run from the script editor), and BetterLog doesn't work in custom functions either because custom functions are run as an anonymous user.

I'm having a weird issue where the function works in the script editor but not in the sheet.

Unless you're speaking some foreign language, "Moblie" and "Accomidations" are misspelled field names, better fix those before someone else ridicules you. Also consider whether those extremely abbreviated field names are really worth the minuscule savings in typing over the large gains you could have in code readability/maintainability.
If I was grading a project, I'd deduct points for that sort of naming.

Remember that double quotes can be used to quote identifiers such as field names, letting you use names that would otherwise clash with reserved words too.

As for the syntax, if your DBMS eats it, it should be fine? It's not how I usually write foreign key constraints but I think yours is ANSI SQL compliant.
Except, I'm not sure what this declaration is supposed to do:
CONSTRAINT FOREIGN KEY(ADID_C,OID_C,CCID_C,TID_C)
Do you really need that? I mean, you declare all those as foreign keys anyway.

Why are your record ID's of CHAR type instead of INTEGER type? Good practice is to either use auto-incrementing ID numbers for records, or use auto-generated GUIDs for them. (Only use GUIDs if your DBMS has a native GUID data type.)

StackOverflow is a giant sociology experiment to find out that, yes, when you incentivize people with achievements and points, they will put in the minimum effort to get those things, at the expense of actually being useful.

And since you give the people that do the bare minimum power, of course they use it to mark every question ever as a duplicate, even if it's clearly not, because they're not willing to put in the effort to find out if it's actually a duplicate, and it's quicker than writing an answer for the same number of points.

You seem bitter. I've gotten good use out of SO, both for searching for solutions to problems other people have had and for asking questions that haven't been asked before. It's not as good as good documentation, but sometimes that documentation isn't available, and rarely you encounter an issue that doesn't have an obvious/documented solution but does have a well-known-to-insiders solution.

SO is fantastic for "beginner questions" that are relatively trivial for someone who already has a deep knowledge of the problem domain to see what the issue is. The gamification really encourages those domain experts to churn through those problems and provide answers quickly.

It's way less useful once your question requires actual effort to answer, because most people (even if they are domain experts) move on to easier questions instead of bothering.

Linear Zoetrope: Nov 28, 2011; A hero must cook

Yeah, I don't ask many questions on SO. Generally I find most of what I need doing documentation searches or experimenting myself. I have asked questions on SO when I've spent a very long time looking for an answer, or if all the documentation is outdated, but usually I end up getting a well upvoted question with no answer, or an extremely poor answer. The only times I get a good answer tend to be times where the answer is "this is a consequence of a known issue <link to bug tracker>" explaining why I couldn't figure it out, because it wasn't working as intended.

If I'm looking for something I don't entirely understand but probably could find eventually, but I need it answered quickly, I tend to just ask here because I won't get closed as duplicate/vague and downvoted into oblivion because I didn't guess the magic words I needed to find the answer to a poorly asked question from 3 years ago.

Same code, and it has no inputs. I'm running Chrome but nothing that would use the GPU a lot. I guess it might be running out of memory, I could try running two instances of the program at the same time and see if they fail twice as fast.

Yeah, this is the big thing. I've gotten really good responses for the JOOQ and the Microsoft Azure ADAL4J libraries, since the devs seem to be monitoring SO.

Honestly, most of the time writing up a half-decent question for SO leads me to solve my own problem. You need to be able to reproduce the issue in a toy-problem in about 50 lines of code if you want anyone to bother reading it, and you need to limit your example code to only use the one library you're asking about, and you need to clearly state what you expect your code to do and what it is actually doing.

What is a good example of a simple CPU to use if you want to experiment with writing an emulator or assembler or something?

I've been writing a CHIP-8 emulator for Haskell and it's pretty easy to work with. There's some quirks, but it's a lot simpler than other architectures (only about 30 opcodes, a fairly regular register set, and not too much weird stuff except the delay/sound timers, and those are pretty easy to understand.)
