rot13xor··on Runescape gold more valuable than Venezuelan currency (2022)
Real life money for gold is sanctioned by Jagex if done through bonds. Bonds are about 3x more expensive than the black market but bonds can't get you banned because Jagex gets a cut.
rot13xor··on Meta to ask many managers to become individual contributors or leave
Communication overhead, like edges in a graph, scales quadratically. The computing analogy is going from 1 core to 8 core CPU gives far less than 8x performance if your task is not parallelizable. The solution is compartmentalization and clear interface boundaries, which is why microservices are so popular. Instead of 5k people working on 1 project, have 100 projects each with 50 people plus a few architects who define the interfaces.
rot13xor··on Reverse-engineering the conditional jump circuitry in the 8086 processor
I always wondered why x86 has LEA when its functionality can be replicated by ADD. It has to do with LEA and ADD being able to run in parallel because LEA uses a separate ALU in the address calculation part of the chip, not the main ALU.
rot13xor··on Ask HN: Someone is proxy-mirroring my website, can I do anything?
You could have a "stolen content" pure HTML/CSS banner that gets removed by Javascript. Only proxy site visitors will see the banner because the proxy deleted the Javascript.
rot13xor··on Criticizing Computers
I had to reboot my Windows PC at least once every few days back in the XP and Vista era. BSODs were common especially while gaming. I think moving GPU drivers out of the kernel into userspace made a big difference as GPU driver crashes are now recoverable. Nowadays I can go weeks or months without rebooting, only rebooting for forced security updates.
rot13xor··on Twitter to employees: all office buildings closed, badge access suspended
It's counterintuitive but Tesla shareholders might want Twitter to fold quickly so Elon can fully focus on Tesla again.
rot13xor··on Musk’s first email to Twitter staff ends remote work
Being smart in one field doesn't translate to being smart in another field. For example, Steve Jobs making medical decisions, doctors making investment decisions, bankers making tech decisions.
rot13xor··on The most unethical thing I was asked to build while working at Twitter in 2015
Some optimizations might only apply to certain inputs that are used by benchmarking software. Or the driver makes unfavorable power tradeoffs to maximize performance when a benchmark is running. For example, if the driver knows a benchmark is single threaded, it can artificially throttle other cores and boost the core the benchmark is running on. There's more extreme stuff like GPU drivers replacing shaders (benchmarks don't care about graphics quality) or pre-rendering frames. https://videocardz.com/74912/professional-overclocker-demons...
rot13xor··on Ask HN: Has anyone here worked on the Windows kernel?
"Write once, run for 20 years" is a strong value proposition. I dabbled in web dev and it's rare for third party libraries and services to go a year without breaking interface changes. Meanwhile a program written for Windows XP will likely still run on Windows 11 even without a recompile (perhaps the source code was lost). In the worst case you might have to run the binary in XP compatibility mode.
rot13xor··on Talking about layoffs
I think the bigger problem with Coinbase is how they rescinded job offers. Management either didn't know a layoff was coming a few weeks ahead of time or it didn't get communicated to recruiters.
rot13xor··on Notice of termination of Twitter merger agreement
I'm curious what would happen if Twitter stock price goes above Musk's offer price of $54.20 during this legal battle.
rot13xor··on Notice of termination of Twitter merger agreement
Money lets you put weight on the scale to tip it in your favor, but it doesn't let you fully control the outcome. Especially because in this case Musk screwed over other rich people.
rot13xor··on Unity is laying off hundreds of employees
It's a good view to have. HR stands for human resources. The company views you the same way as a EC2 instance. They make layoff decisions the same way they spin down servers if their AWS bill gets too high.
rot13xor··on Former Apple exec who enforced insider trading rules admits to insider trading
He probably didn't think he'd get caught or ego.
rot13xor··on Even your boss wants to quit
I'd even say you need a degree of sociopathy to reach upper management. I can't imagine being responsible for 1000 other people and keep them working in sync. At some point those people become a faceless resource in a spreadsheet.
rot13xor··on Even your boss wants to quit
In California the top marginal tax rate can be over 50%. 37% federal tax, 12% state tax, 3.8% net investment tax.
rot13xor··on The computers are fast, but you don't know it
Regarding chrome, browsers are basically operating systems nowadays. A standards compliant HTML5 parser is at the bare minimum millions of lines of code. Same for the renderer and Javascript engine.
rot13xor··on The computers are fast, but you don't know it
The biggest weakness of C++ (and C) is non-localized behavior of bugs due to undefined behavior. Once you have undefined behavior, you can no longer reason about your program in a logically consistent way. A language like Python or Java has no undefined behavior so for example if you have an integer overflow, you can debug knowing that only data touched by that integer overflow is affected by the bug whereas in C++ your entire program is now potentially meaningless.
rot13xor··on “Downthem” DDoS-for-hire boss gets 2 years in prison
And if you didn't pay taxes on your illegal income the feds get you for tax evasion too, like how they got Al Capone.
rot13xor··on Why did InterlockedIncrement/Decrement only return result’s sign? (2004)
Parity is cheap to calculate in hardware but much more expensive to do purely in software. See https://stackoverflow.com/questions/25707130/what-is-the-pur...
rot13xor··on Ask HN: What to do about ‘Good at programming Bad at Leetcode’
2 months of studying every 2 years for job switch is 8.3% overhead. Do leetcode jobs pay 8.3% more after-tax than non-leetcode jobs?
rot13xor··on Ask HN: Is anyone else glad the crypto market is crashing?
The crypto believers told me US dollar would enter hyperinflation very soon and Bitcoin will be the only viable currency because it has a finite supply.
rot13xor··on I got an FBI record at age 11 from dabbling in cryptography (2015)
I'd expect Costco would require receipts for returns, even for online purchases, like most stores. Then the store would only refund the amount after discounts. But perhaps Costco is more trusting of their customers because they have to pay for membership.
rot13xor··on T-Mobile begins blocking iPhone users from enabling iCloud Private Relay in US
Cell carriers can detect video streams by bandwidth and traffic patterns even with encryption. https://security.stackexchange.com/questions/172212/how-do-m...
rot13xor··on Elizabeth Holmes found guilty
I assume you could buy the stuff from the company's bankruptcy auction or when it gets auctioned off by the Feds like in the case of Martin Shkreli's exclusive Wu Tang album.
rot13xor··on An opinionated guide on how to reverse engineer software
Microsoft once had to release a binary patch for Office to fix a security vulnerability in an addon where the source code was lost: https://news.ycombinator.com/item?id=15720923
rot13xor··on Google introduces mandatory 2-Step Verification for Google Accounts
Some work machines have all external ports glued shut and the mouse/keyboard are non-removable to prevent data exfiltration. Though you shouldn't be logging into personal accounts on those machines anyway.
rot13xor··on Retailers are spending millions to combat organized theft from stores
Eventually all stores are going to require a membership or deposit before letting you enter, like Costco.
rot13xor··on GateBoy – A gate-level simulation of the original Game Boy hardware
Latches or a ring oscillator to generate true randomness. There could also be bugs in the design that cause metastability.
rot13xor··on Show HN: A work-in-progress C compiler from scratch
C is almost context-free with the exception of typedef. A custom parser helps with error diagnostics, e.g. missed semicolon or a "." swapped with "->".
