How I cut GTA Online loading times by 70%
GTA Online. Infamous for its slow loading times. Having picked up the game again to finish some of the newer heists I was shocked (/s) to discover that it still loads just as slow as the day it was re
This is a technically engaging read, the author got annoyed at really long load times in GTA:O and decided to do something about it.
I’m also surprised, given that this game is such a huge cash cow, that no one from Rockstar thought to ever profile this code given that their load times were >6 minutes and this would have stuck out like a sore thumb in any profiling.
“If this somehow reaches Rockstar: the problems shouldn’t take more than a day for a single dev to solve. Please do something about it :<
You could either switch to a hashmap for the de-duplication or completely skip it on startup as a faster fix. For the JSON parser - just swap out the library for a more performant one. I don’t think there’s any easier way out.”Posted on 2021-02-28T23:13:53+0000

How Google's Grand Plan to Make Stadia Games Fell Apart
The tech giant hired 150 game developers for Stadia Games and Entertainment, only to lay them all off. Sources say it never gave the studios a chance.
“It is miraculous that successful large-scale games get made at all, anywhere. A big-budget game can be beautiful, but does the “jump” feel good? It can piece into a popular genre, but is it too same-y? Does the plot make sense? Are the characters balanced? And, most of all, is it fun? There is no potion to drizzle into the fizzing cauldron of game development to produce a hit; it takes all kinds of people channeling their personal inspiration into one multitudinous commodity. It’s crazed and human. That’s the alchemy that tech giants still can’t solve for.”Posted on 2021-02-27T09:16:23+0000

Absolutely infuriating, especially when you get through so much of the slowly building rage and then get to this quite, having internalized the full context of the situation:

Google's program for Black college students suffered disorganization and culture clashes, former participants say
Program participants said the company moved too fast and broke some things.
On one hand, I’m happy they tried to work on this problem. On the other hand, bungling the execution like this can do more harm than good. On the third hand, I don’t believe any other large silicon valley employer would be able to do better either because the problem is so structural.
There are too many quotes to pick out - I’ll pick the one that struck me the most:
“"It was like nobody had seen an African American person before," said 2018-19 student Saraah Cooper, describing her everyday experience on Google's campus.
"A regular Google employee came into the game room and asked us for all of our IDs and we were kind of confused because he wasn't security or anything," said 2018 scholar Afeeni Phillips.
"There was this lady in front of me in line for a food truck and she turned around, looked me in my eyes and said 'this line is only for Google employees — you can't eat here,'" Tolbert recalled, adding that he considered the incident a symptom of broader issues not exclusive to Google's campus.

Really looking forward to the next post in this series.
“This has been a deep dive into the world of branch simplification, with an emphasis on how we engineered Cranelift’s new backend to provide very good compilation speed taking control-flow handling and branch lowering/simplification as an example. We believe that there may be other significant opportunities to rethink, and carefully engineer, core algorithms in the compiler backend with specific attention to maximizing streaming behavior, minimizing indirection, and minimizing passes over data. This is an interesting and exciting engineering pursuit largely because it goes beyond the world of “theoretical standard compiler-book algorithms” and calls on problem solving to find clever new design tricks.”Posted on 2021-02-21T03:42:41+0000

Citi Can’t Have Its $900 Million Back
Also Morningstar CMBS ratings, just another SPAC, SPAC lawsuits and ClubHouse.
Shitty software UX leading to large money losses again, take #28581. The exposition of the actual bug as it happened and the screenshot of the software are scary. Also interesting was the callout from the judge that the recipients thought the payment was legit because they only started joking about it on their internal chat a day later - after they found out it was a mistake.
I should probably start subscribing to Bloomberg since Matt Levine’s columns are always solid.
“Last August, Citigroup Inc. wired $900 million to some hedge funds by accident. Then it sent a note to the hedge funds saying, oops, sorry about that, please send us the money back. Some did. Others preferred to keep the money. Citi sued them. Yesterday Citi lost, and they got to keep the money. I read the opinion, by U.S. District Judge Jesse Furman, expecting to learn about the New York legal doctrine of finders keepers—more technically, the “discharge-for-value defense”—and I was not disappointed.

Why did I leave Google or, why did I stay so long?
Published via Paygo
This leaves me with a lot of mixed feelings. It's a blogpost by the founder of Waze on his experience at google and why they left N years later.
I was first nodding along with agreement as a bunch of things matched my experience at a bigco (for better or worse). But then some of the later sections around work-life balance, compensation, and transparency/directness left me with a bad taste in my mouth - in some cases I'd expect the author here to have more control over the things they are complaining about; and in others... well, I don't think 'd enjoy working with them.
"If I had to summarize it, I would say that the signal to noise ratio is what wore me down. We start companies to build products that serve people, not to sit in meetings with lawyers. You need to be able to answer the "what have I done for our users today" question with "not much but I got promoted" and be happy with that answer to be successful in Corp-Tech. I guess that's just not me. As the tech regulation / anti trust heats up - the noise will continue to get louder than the signal. The innovation challenges at Corp-Tech will only get worse as the risk tolerance will go down.

Slate Star Clusterfuck
On journalism, ideas, "ideas", free speech, and tech.
This was an interesting read on the whole mess that started after the NYT piece was published the other day. I haven’t been following things closely (and I had read some SSC here and there but not regularly) - the perspective here was quite useful to understand what’s going on.
“This demand for unalloyed positivity is exacerbated by a reactionary grievance culture in some corners of the tech industry that interprets critique as persecution, in part because of a widespread belief that good intentions exculpate bad behavior. Why be critical of people who are just trying to change the world? (Through their casual gaming app that allows people to group digital candy in sets of three, or their gig economy platform that has the effect of driving wages well below standard minimums, or their social network that may be responsible for an active decision to algorithmically distribute disinformation because that’s what the customer apparently wants?)

The effect of switching to TCMalloc on RocksDB memory use
Memory allocator is an important part of the system, so choosing the right allocator for a workload can give huge benefits. Here is a story of how we decreased service memory usage by almost three times.
Memory allocators are hard!
“Usage of an allocator which is not optimal for a workload can cause a huge waste of memory. If you have a long-running application with a lot of threads and care about memory usage then glibc malloc is probably not your choice. Allocators that are designed for multithreaded services, like TCMalloc, jemalloc and others can provide much better memory utilization. So be conscious of this factor and go and check how much memory your application wastes.”Posted on 2021-02-15T02:56:48+0000
Black CA couple lowballed by $500K in home appraisal, believe race was a factor
The Austin family sunk $400,000 into renovating their home, but were stunned when they barely gained any value during the appraisal process. When they had a white woman pose as the homeowner, that all changed.
Where do I even begin...
“"We had a conversation with one of our white friends, and she said 'No problem. I'll be Tenisha. I'll bring over some pictures of my family,'" Austin said. "She made our home look like it belonged to her."
The home appraised for $1,482,000, or roughly $500,000 more than it appraised for just weeks prior.
The change was equal to a nearly 50% increase in value.”Posted on 2021-02-14T20:12:26+0000

Beyond Burned Out
Chronic stress was rampant even before the pandemic. Leaders can’t ignore it any longer.
Only read the first two articles in this series so far but it’s resonated a lot and I keep nodding along. So much insightful stuff on burnout, and how it’s being horribly mismanaged.
“When you analyze the real causes of burnout, it becomes clear that almost everyone has been attacking the problem from the wrong angle. According to Christina Maslach of the University of California, Berkeley, Susan E. Jackson of Rutgers, and Michael Leiter of Deakin University, burnout has six main causes:
Perceived lack of control
Insufficient rewards for effort
Lack of a supportive community
Lack of fairness
Mismatched values and skills
While these are all organizational issues, we still prescribe self-care as the cure for burnout. We’ve put the burden of solving the problem squarely on the shoulders of individual employees. “Let’s just recommend more yoga, wellness tech, meditation apps, and subsidized gym memberships — that’ll fix it,” we say. But those are tools for improving well-being. When it comes to preventing burnout specifically, they won’t be effective. We desperately need upstream interventions, not downstream tactics.”Posted on 2021-02-13T07:34:05+0000

Ten doses of the Covid-19 vaccine would expire within hours, so a Houston doctor gave it to people with medical conditions, including his wife. What followed was “the lowest moment in my life,” Dr. Hasan Gokal said.
Continuing on the topic of the bungled vaccination rollout in the US, this is depressing - not using a vaccine and letting it go to waste *should* be criminal - what he did should be fine.
"The officials maintained that he had violated protocol and should have returned the remaining doses to the office or thrown them away, the doctor recalled. He also said that one of the officials startled him by questioning the lack of “equity” among those he had vaccinated.

Exactly, he said he was told."Posted on 2021-02-11T17:29:55+0000

Her husband is the primary breadwinner in their family, so she knows that is part of the answer. But on this day, it was as if the world was rubbing it in her face.
Mila was crying to play and Eddie kept telling her “later” — then disappearing into his office. While Mercedes was on the phone with a client whose mother had died, Mila began screaming “MAMA!” and Eddie began popping popcorn. Later, as she worked, trying to keep Mila entertained, he took a nap on the couch.”Posted on 2021-02-05T16:39:21+0000

Introducing 'Food Grammar,' the Unspoken Rules of Every Cuisine
Technically, spaghetti and meatballs is bad grammar.
“Consider the adjective “hungry” in English, a concept conveyed with the noun hambre in Spanish. By imposing Spanish grammar on the English sentence, you get the phrase: “I have hunger.” Pretty, maybe, but odd. Similarly, someone attempting to recreate a foreign cuisine may find that their native grammar sneaks into their conception of the meal. As a result, trying your home food abroad can prove disorienting: Parisian restaurants may serve a hamburger with a fork and knife; a Japanese restaurant serving yoshoku, or “Western food,” might place croquettes and cabbage rolls in a bento-like box along with tiny portions of pickled vegetables and miso soup. In China, explains Jennifer 8. Lee, author of The Fortune Cookie Chronicles, rice is served after the main and before the soup, making the American-Chinese tradition of serving white rice alongside the main seem as odd to Chinese diners as an English-speaker hearing a foreigner say “old silly fool” instead of “silly old fool.””Posted on 2021-02-02T06:22:14+0000
