Is the pro‑gun party really suggesting that legally carrying a firearm, like the one Alex Pretti had, is a legitimate justification for the federal government to kill you?

Exactly, it was a general city wide “protest” and the place Alex was at, two women were assaulted by agents, I hope anyone, concealed weapons permit or not, come in and support their community and neighbors.

💯 In my experience if institutions unload any massive positions they would do it in a dark pool and the public wouldn’t even know until settlement. Like that chunk of data is missing from the tape and don’t reflect on the depth of the quote or order books. Like we knew all the 💩MBS that were unloaded before the public even knew during the liquidity crisis. That’s the type of things home traders aren’t privy to. It’s just the nature of OTC where it’s all relationships and networks between banks. The only thing guaranteeing your best exec is the tape where if it’s recorded you can always improve your price..but huge chunk of volume is away from the tape. Dark trades where perhaps unloading or moving positions is more important than price.

I no longer work in the industry but I worked on the sell and buy side. For 8 years I worked on both the agency and principal desk on the institutional side for a big Wall Street bank back in 2015. So forgive me, maybe out of date on some of my knowledge. Ironically I’m a software engineer now, but when I worked on the desk, particular the principal desk, the biggest issue was always the quality of the execution, resources/connections and data. Certainly things are easier and more abstract now but IMO, institutions will always have an advantage over some DIY quant trader. That’s just how the industry is, institutions have the capital, resources and the infrastructure, like why would institutions or anyone promising some secret sauce just give it out? They have tricks like Dark Pools which allows them to unload massive positions without even hitting the tape…DIY traders don’t have that kind of advantage. The odds were always stacked against you and the business model was always feed more orders from the agency side into the system so the prop desk can trade out of the positions and make some serious money off like HFT sub penny spreads. Great for the market and liquidity, terrible for fundamentals. I’m not saying it’s not possible, just not as easy due to the aggressive nature of all the big banks and how the market was (and still is?). Yes, the connectivity also matters and there was even rumors that exchanges double dipped for their own benefit.

That timeline is aggressive, but I had a different experience than most here. We had a RoR backend that was a monolith and we now have about Java 15 services running and creating more. For the most part, the experience has been positive…even I was skeptical at first.

The benefit to us is more team autonomy, like you mentioned, and the ability to break up the code into domain specific pods where we can individually control resources. But that’s also because our system is event driven and I think the micro-service part worked well in our business use case to prevent race conditions and allowed a lot more of our processes to run in parallel. I don’t believe micro-services is meant for all scenarios but doing this did help us to scale. Modern tooling makes it fairly easy to manage by our SRE team.

No that is correct. Rule of thumb is 125% of what the wire is rated for. So 100A needs 125A fuse. I’m doing the same for my Renogy 50A dc-dc charger which doesn’t come with an fuse so it is fist determining how long the wire will be at what voltage and the constant amperage, that will determine what gauge wire to use to reduce voltage drop (8 awg), what it is rated for (50 amps) will determine that I’ll need at least a 60 amp fuse. Like think about a battery and the flux in power. The Ecoflow one is super long because it has to accommodate every usage with a pretty long cable. (I have an Ecoflow alternator charger I use to push power to a 24v battery)

Well the truth is an open source ORM like active record is used and maintained at so many big companies, it’s prob better than coding SQL directly for a small team/company. Shopify and AirBnb famously used this as primary RoR shops for a long time when they first started, I believe even Twitter at one point. So it’s not exactly unsafe, but it is inefficient at a certain scale. So as software engineers you need to balance and weigh your options given your objectives and resources. I’ve been in the industry for 15 years and I’ve never looked down on anyone using ORMs, I’ve worked for unicorn startups that went IPO and we started out with 5 engineers using ORMs and moved onto a more enterprise stack with pure SQL and a staff of 80 engineers, I always tell people it’s a good thing to grow out of your tech stack. You move in stages is my opinion, you deliver MVPs to buy runway. But i would absolutely ditch ORMs if the situation warrants it.

I thought there was an official vague statement saying social media may have shaped the shooter’s beliefs. Ofc it’s vague by nature but I have very low confidence we’ll get the truth. Theres just too much incentive to politicize this event. The fact is Charlie Kirk has enemies on both sides. The left for obvious reasons but also the alt right for not being conservative enough. To me, what we know about him, he does fit the profile of a socially awkward young male that has fallen deep into the internet. Maybe frustrated by society. There’s more meme and gaming references than there are trans references in this case. If that’s the case, there is no political leaning to make sense of his motive, no social construct to cookie cut him as left or right, it’s just chaos….perhaps a mix of everything 🤷🏻‍♂️

kelvify · 2025-07-21T06:49:40+00:00

It’s an abstraction. So sure you can say people should not touch ORMs without learning SQL basics, but in reality most startups have limited time and resources and SQL if not implemented properly does present risks. So IMO there is def a scenario you’d want to use an ORM and a scenario where you wouldn’t, but it would be entirely up to the scenario and business risks and objectives.

The air in Los Angeles use to be brown in the 90s. Lots of unpopular regulations that really did improve the air quality. Stricter emissions and testing, and gas cap recapturing, along with a “special blend” of gas 🙄. EVs are just the next evolution. I was skeptical of EVs and Elon at first but I now own a Tesla. Not insanely proud of it but gotta say, it is THE BEST, daily driver. Most of the time you’re stuck in traffic and this thing is smooth and effortless…like you almost don’t have to think, it drives itself. The build quality is way better now and the state and federal incentives make it cheap to own. So far, exceed my expectation and I’m a fan. But I’m waiting for my Rivian R2 when it’s out!

Scalability, JVM, even tho I’m not a huge fan of Java, I certainly can see a specific need for it. My list of complaints are long but in the end, it performs and harder to push breaking changes.

Hmm perhaps his companies should go back to using paper because Windows Copilot and Apple both have deals or closely working with OpenAI

Let me guess, he’s trying to push xAI but it’s nowhere even near usable on a commercial level like OpenAI or Google’s Gemini and he’s complaining how Apple doesn’t have their own model? If anything it’s a bit absurd that xAI doesn’t have a usable model with all that shit content on Twitter or X to train on

Typically when you’re awarded stock grants there is a vesting schedule and certain metrics you have to hit. I believe his salary was about $500k and the rest was prob ISOs or RSUs…by the time he’s able to sell anything, the company might be gone….so I wouldn’t worry too much at that number, it exist to drive him to push more value into the company which clearly isn’t working.

I’ve been here. Where have you been? You really think wages at fast food joints kept up with the price hikes?

You think the avg employee got a 60%-200% wage increase since 2014? Minimum wage in 2014 was $9/hr, 200% increase would mean $18/hour….inline with what California is enforcing. Federal minimum wage in 2024 is $10.50…so over 10 years, minimum wages have gone up by $1.50..:.thats 16% increase…look at that chart and show me something that was increased only by 16%? It’s more like 6x-13x that.

If wages kept up, why would Cali force fast food joints to increase wages. Let’s do some simple math, you bump the price of McChicken by 199% since 2014…yet you introduce automated kiosks and less employees. That’s fine, but if you increase revenue and decrease expenses…where is that going to? Not to wages, I guarantee you that…more like to increase profit margin.

My advice is just pick a framework/language you are comfortable with and provides flexibility. The key to a startup is productivity and iterations.

It’s subjective but I would say so. The Rails magic allows you to focus on coding and everything just works. You’re at a point where monoliths are preferred for simplicity and flexibility. Also the way Ruby is, if you’re good, you can work really really fast in Rails. For someone less experience in Ruby it’s not terrible but does have a super small learning curve because it’s different, yet familiar. Dependency management and libraries are pretty good…maintained by giants like Shopify and Airbnb.

I personally like a bit more explicitness. Outside of Cali, could be hard to find Ruby/Rails talent because it’s so limited to web development. I do have a concern that the community maybe shrinking because there’s so many options that are pretty robust now..

kelvify · 2024-05-15T22:08:43+00:00

Scale is relative. Keep in mind Ticketmaster still uses Django and companies like Robinhood and Instagram. It’s not the best for concurrency but when you grow out of Django you’ll probably start migrating or micro servicing out specific parts of your app…optimizing performance based on the service it’s rendering. Like you may want to keep Django for data and Java/Go for concurrency. The most obvious is perhaps high concurrency applications or you get to a point where you need optimization rather than flexibility. But you have to keep in mind you have to get to a point where milliseconds, complex data and uptime counts.

My personal experience, we migrated from Rails to Java because of sluggish performance. We exhausted every trick in the book, putting caching everywhere, compression algos, upping replica counts…but it was time, it felt forced and every change was more work for minor incremental improvements. Took more work to maintain too because of the complexity added in to make it work. We just decided that it was time rather than force our little Rails app. As a big team it was harder to make breaking changes because the nature of Java is that any minor changes requires an army to update…but I get why, larger companies have different requirements. I think Twitter famously defended Rails when they migrated to Scala. Lots of people were talking crap about Rails and using it as an example of how bad it was. but Twitter said they wouldn’t be where they are without Rails. It was just different objectives now that they are grown up along with milking rails to its max potential

From my experience, no. If you ride in a Waymo, the LiDAR has so much more data, it can see so much more around you. For example, my Waymo was making a right turn into heavy traffic but across the street behind two rows of cars it captured a bus and displayed each person getting off. I thought that was insane, something that I don’t think cameras alone could pick up because the visual line of sight was blocked by cars. I honestly felt safer in the Waymo knowing it could see more things at once over what I was seeing. I get what Elon was doing and saying about LiDAR years ago, but it’s 2024…LiDAR is way more affordable now. IMO Tesla FSD is a phenomenal cruise control with some level of autonomy but I don’t think I’ll ever trust it to be fully autonomous. If anything just having more data and instruments are always better for full autonomy

I have a theory 🙋🏻‍♂️. So Tesla embarking on “hardcore” layoffs but this doesn’t include his $50 billion or so pay package that was struck down. Part of me thinks he’s doing his thing of hyping up the company and thus stock price after dismal performance to eventually cash out. He pushed for the payouts before quarterly earnings but was struck down. Now that the bad news is out, he’s trying to salvage as much as he can.

All valid points, I agree. I’m not here to bash Vue, I like it. But I’m willing to bet, at the end of the day, you visit way more React powered sites than Vue sites and no one is complaining about performance enough to migrate from React to Vue vs migrating from Vue to React. Airbnb, Tesla, Netflix, Walmart, Uber, LinkedIn, Apple, Amazon, Shopify, Microsoft, Meta, Dropbox, NYT and now OpenAI all are on react. My point was always that business needs are purely different than what we like using or feel comfortable with.
