ielillo commented on Ask HN: Should there be new RPN calculators to replace the TI-84? · Posted by u/idatum
For many business-type courses they like you to be able to quickly get an IRR or NPV value. One could solve that by hand, but the exams would be long and require manual grading. According to my older colleagues when I started my career, they used to bring their HP calculators to client meetings before laptops were a thing. They would sit around and do estimated calculations. If you look at old photos, your can see the HP calculators in them and paper with written calculations. When I started my career in 2000, laptops were already ubiquitous. There were still old timers with the RPN calculators from HP. Excel is better for finance. For real analysis and simulation stuff like Mathmatica and Maple are better, with SAS, SPSS and R for statistics, although SAS is used a ton in finance, insurance as well as government.
That's another point, during college some tests were and multiple choice questions. They were manually graded and for each answer you needed to prove how did you get the answer. I don't remember any kind of automated grading system. Everything was done by hand, whether by the teacher or TA's

IMHO we'd be better off focusing on policies that allow computers to be used on standardized exams. Hardly anybody uses a calculator in a real job, people at desks use computers, and even people who have to do calculations in a field environment use ruggedized tablets. Rather than working on revamping obsolete technology we should work on a way to make a computer acceptable to use on an exam in a way that addresses cheating concerns.
But if you really wanted to keep using a calculator, you should check out the HP Prime, Casio Prizm, or TI-Nspire series. The HP Prime has RPN, and all of these lines have color touch screens and a bunch of modern features. The TI-84 is not the pinnacle of technology, it is popular only because it is an exam-acceptable and an old standard format that people are used to.
From my college experience I never needed a Ti or Hp calculator. Most of the questions did not require anything more complex than logarithms, exponential, root and trigonometric functions. A good question should be about concepts, not results. I remember a linear algebra test in where you had to solve a problem by inverting a matrix to get a result, the problem was that the matrix was so large that it could have taken the entire test time to get the result if done by hand. However if you were clever, and knew the matrix properties being tested, the matrix could be simplified and the result gotten in 3 steps. If you had a Ti or HP you could have entered the matrix and get the result, but the question would have lost its meaning

google argued with me. a lot. I went to school but didn't graduate. not something they were prepared to deal with. never claimed I had a degree. but the fact that they called the school and the school said I didn't have a degree was a huge red flag.
I did a startup. the year before we were incorporated I was doing prototypes and fund raising. We called the company and you're weren't employed until 20xx, but you listed 20xx-1 as the start date! now you're in trouble.
I’ve known people who has dropped out of college after receiving job offers during their internships. The problem is that some companies cap your your maximum pay and promotions unless you finish college even though you had excellent performance reviews. So you either stay on college and lose the job opportunity, or stay knowingly that at some point you’ll have to come back to college to finish your degree.
>The Java-chip thing proved more difficult to realize than anticipated
I've been very slowly upping my Java-fu over the past year or so to crack into the IC market here in the Nordics. Naturally I started by investigating the JVM and its bytecode in some detail. It may surprise a lot of people to know that the JVM's bytecode is actually very, very much not cleanly mappable back to a normal processor's instruction set.
My very coarse-grained understanding is: If you really want to "write once, run anywhere", and you want to support more platforms than you can count on one hand, you eventually kind of need something like a VM somewhere in the mix just to control complexity. Even moreso if you want to compile once, run anywhere. We're using VM here in the technical sense, not in the Virtualbox one - SQLite implements a VM under the hood for partly the same reason. It just smooths out the cross-compilation and cross-execution story a lot, for a lot of reasons.
More formally: A SQLite database is actually a big blob of bytecode which gets run atop the Virtual DataBase Engine (VDBE). If you implement a VDBE on a given platform, you can copy any SQLite database file over and then interact with it with that platform's `sqlite3`, no matter which platform it was originally built on. Sound familiar? It's rather like the JVM and JAR files, right?
Once you're already down that route, you might decide to do things like implement things like automatic memory management at the VM level, even though no common hardware processor I know has a native instruction set that reads "add, multiply, jump, traverse our object structure and figure out what we can get rid of". VDBE pulls this kind of hat trick too with its own bytecode, which is why we similarly probably won't ever see big hunking lumps of silicon running SQLiteOS on the bare metal, even if there would be theoretical performance enhancements thataways.
(I greatly welcome corrections to the above. Built-for-purpose VMs of the kind I describe above are fascinating beasts and they make me wish I did a CS degree instead of an EE one sometimes.)
IIRC correctly the original Java VM was a stack based machine. That made sense when it was first created since a stack based machine is the simplest system you can create that run code and since it only need three registers, one for the instruction, one for the first data and one for the top of the stack for the other data. The problem is that you need to push and pop a lot from the stack during runtime which means more memory accesses and more time spent on gathering the data than on doing actual operations. That also underutilizes the processor registers since on a normal processor you would be using two data registers at most. This was one of the early issues with java running slowly on android and the reason of the creation of the Dalvik VM which was a register one.
Were there any games or apps specifically tied to these cards, or did everything go through D3D at this point?
I remember some earlier titles that were locked to specific cards such as the Matrox ones and didn't support any other accelerators.
From memory unreal tournament and other fps that used the same engine had support for opengl, glide, d3d , s3tc and software rendering. It was one of the most compatible render engine

But at the same time, obedience, discipline and chain-of-command are ingrained in military culture (do correct me if I'm wrong, my main sources are movies and propaganda). But also trust, trust that e.g. your commanding officer knows what they're doing, considered the risks, and takes responsibility. They too in turn make decisions based on what they know / are told; if there's civilians in a target but intelligence doesn't say so, are you or your chain of command guilty of a war crime?
Not sure if you read Generation Kill or watched the miniseries, but that is one of the main points. In there, there were two platoon commanders, Lieutenant Fick and Captain America(The book never reveals its name, and I think the series does, but I don't recall at this moment). While Lieutenant Fick was a competent officer that tried to kept the welfare of his troops, he often butted heads with its direct superiors since the order given to him could endanger the lives of his subordinates while not accomplishing nothing of value. In contrast Captain America, was an incompetent officer who gave reckless orders, was ignored by his troops and could have been possibly be charged with war crimes. At the end of the series, when the journalist is interviewing the battalion commander about why Captain America was never disciplined for his actions, the battalion commander answers that the same leeway that he gave to Lieutenant Fick was given to Captain America. In other words if he were to punish Captain America, he should also be punishing Lieutenant Fick. In retrospective is understandable, but when you read or watch it, you wonder why no action is being taken to discipline Captain America and why no one listens to Lieutenant Fick

Until the US changes their AC power connectors, we just don’t have a use case for it frankly. When the entire system is going to always top out at 1200W or so (so you have an extra few hundred watts for monitors and such), we’re pretty limited to maximum amperage.
The USA has 240 volt plugs. They are only used for high power appliances such as AC or ovens. If you want, you could add a plug for your high powered space heater AKA gaming PC.
I remember reading that rodents chewed car cables since the insulation was made using the same compound as soy and that attracted them, but in reality it was just they liked chewing on stuff.

ielillo commented on Ask HN: What is interviewing like now with everyone using AI? · Posted by u/ramesh31
"Drawbacks" was the wrong word to use here, "potential problems" is what I meant - collisions. Normally a follow up question: how do you solve those. But drawbacks too: memory usage - us developers are pretty used to having astronomical amounts of computational resources at our disposals but more often than not, people don't work on workstations with 246gb of ram.
I think the better word is tradeoff since there are no perfect data structures for each job. The hasmap has the advantage of O(1) access time but the drawback of memory usage, an unsorted nature and the depends on a good hashing function to minimize collisions. A vector is also O(1), but it has an upfront memory cost that cannot be avoided. A map has a O(Log(n)) access cost, but has less memory usage, is sorted by nature and the comparison function is easier to implement.
Three similar data structures, but each with its own tradeoffs.
