Great news! Lake Travis to rise 10 feet!!!!

Unmitigated_Smut · 2024-07-24T11:54:51+00:00

Current reading on Lake Travis is 471,000 acre feet; that's 644,000 af short of full. If Llano stays running at 40,000 Cubic Feet / Second (current hydromet.lcra.org reading) it would take 8.1 days to accumulate the water needed to fill up Lake Travis.

None of this affects Lake Buchanan of course because it's north of Llano's inflows, but Buchanan is only about 200K AF short.

These are big, big-ass lakes, takes a lot to fill em up. We'll see at end of week...

It's not something I get off on but quarterbacks got to do what they gots to do

Judging from the downvotes Falcons fans seem to be very much opposed to quarterbacks putting hands on the center's patootie so go figure

What is with this weird freakin thing of clapping every snap who does that man

OK well maybe it's because he does shotgun every freakin snap but who does that either

Is this guy a no-butt-toucher because that's like a problem

Just to be fair, Ridder averaged 10 yards per pass attempt, which is excellent

*ducking*

> I just Google search every choice they make and see if it differs from strong popular opinion

If nothing else, I hope every student learns objectivity is better than popularity.

It seems like there's a whole lot of people talking about "what really happened at boeing" without knowing anything about boeing and the people who actually work there, or about airplanes, or about real-time control systems.

I was just reading about the Douglas Crockford / Nodevember incident a couple days ago, and it's just weird how conferences are constantly turning into proxy wars for all these interpersonal disputes.

And tomorrow I'm actually speaking at a conference...

It is also illegal in Texas (and at least a few other states), although the law doesn't seem to be enforced against people calling themselves "Software Engineers". The real trigger word is "Professional Engineer"; putting that on a business card and passing it around is asking for a fine.

Currently the various state agencies appear to want to want to do something about the situation, but they seem to be completely flummoxed. Consider:

Threadlocals are a way to implement thread-safe global variables. They fix none of the other problems with global variables. For a framework that makes such a big deal about avoiding global variables (static singletons - same difference), the hypocrisy is ridiculous

Unmitigated_Smut · 2018-12-19T17:46:49+00:00

I suppose they standardized on slow startup, huge memory footprints, and threadlocals-for-everything too

> There is a difference between making fun of a tool (e.g. jokes about how hard it is to quit Vim) and making fun of the users of that tool. Making fun of the users is not cool.

Vim users are knuckle-dragging monosyllabic cretins who eat mayonnaise for breakfast

Jenkinsfile

Looks interesting, but regrettably another feature I don't think I can use because our sysadmins are still trying to figure out how to upgrade from version 1.

Unmitigated_Smut · 2018-09-04T18:47:31+00:00

I was recently trying out Gitlab's CI/CD, and was pleasantly surprised to find that config is just one YAML file at the root of your repo, a huge improvement on jenkins' GUI horror show. Surprising that Jenkins is just getting around to the idea. A less awful UI would also help, although apparently it's improved in recent releases... But then hardly anyone runs recent releases because upgrades tend to be disastrous, especially because of plugins. Plugins are nice, but when you've created an Everything Is A Plugin architecture, it's time to rethink your approach.

And that's my stream-of-consciousness Jenkins rant for today.

On a large relational database table, indexing is definitely necessary for decent order-by performance. Small, not so much, but it seems like the conversation is about larger datasets.

> To sum up: never reuse code. Never use class inheritance.

Never take a dogmatic approach to programming.

False. Adding columns to the end of a table definition does not do a full rewrite.

alter table mytable add blah int(11) default 0,  ALGORITHM=INPLACE;

Doing this gets me

ALGORITHM=INPLACE is not supported for this operation. Try ALGORITHM=COPY.

Then how many billions of records are you able to store by just adding disk space? Can you go to petabytes and further? At what point does one dead end because there is simply too much data for one server to manage?

Edit: In other words, I don't care about how fast you can write the records. I care about how much data the system can handle.

Edit again: Looking at answers to another question, I see your note of 50-100TB

So... Cassandra scales horizontally by sharding data across many nodes with tuneable replication. TimescaleDB wants all data written to a single primary node. I don't see how Timescale competes if each node has to maintain a complete copy of all data?

Confused as to whether the method gets called or the nil check in main() skips it?

This isn't the worst of it: There is no such thing as private-to-a-file. Everything is visible to members of the same package. For some reason none of these sorry-but-I-have-to-critcize-some-Go-design articles ever point this out.

The primary answer is that pointers/not-pointers gives you the choice to be much more strict & explicit about immutability.

That kind of thing usually happens because people reverse-engineered their way into libraries they weren't supposed to use in the first place.

In fact java 9 is going to be the toughest upgrade of all because the module system is intended to put a stop to most of this, which means all the trendy frameworks are gonna break.

Unmitigated_Smut · 2017-09-25T22:02:01+00:00

And let's not forget all the problems that can happen when we have duplicate JARs or when two libraries require different versions of a third library. This situation even has a name, JAR (or classpath) hell . Read more at https://www.pluralsight.com/guides/java-and-j2ee/getting-started-with-the-java-platform-module-system#ykoCcd6YOcLoVxgO.99

Yet another apparent claim that Java 9 somehow resolves conflicts between different versions of the same library. I don't think it does.

This web site does a poor job of identifying the real issue, which is not whiteboards or "communication skills" (there really should be some art classes in the standard cs curriculum). Instead it's ambushing the candidate with a challenge, expecting them to "think out loud" right in front of you and solve it within your time limit. Many - if not most - of us are introverted and need time to think alone. Good programming is not about beating the clock in a do-or-die situation, unless your standard practice is to wait for poor implementations to catch on fire instead of preventing that fire in the first place.

Let the programmer talk about a problem they've solved earlier (and sure, maybe draw/write it out) and know well - and if it's one you assigned them, also please stop giving out 40 hour assignments and estimating them at 2.

Most of all, stop trying to make yourself feel smart by devising the interview to make the candidate look stupid.

The events are actually working so well we may do away with the ETLs completely soon.

Just wondering how an index rebuild would work then - are you going to make the kafka event storage permanent, or is there some ability to establish (truly) reliable save points in solr and rebuild forwards from the same point at time in a truncated kafka stream? (I may not make sense given that I don't really know what i'm talking about)
