I haven’t been in a company that has gone bankrupt, but I’ve been in a few that struggled. The biggest problem is usually not the tech. It’s to align the product with the customer needs.
You can have the most advanced tech in the world. If it doesn’t solve anyone’s problems, no one will buy it.
but it will get tons of people that are interested in whatever you’re doing to help for free
Will they though? It requires that some of the target audience are capable to contribute, which is rare in my experience.
Dopamine. Affirmation. Attention.
Although I don’t share that much on social media anymore.
I hate when coworkers tell we should do thing in a particular way because it’s ”better”. We try the thing and there’s no measurable difference. Well, it was a good idea in their mind, so it must be an improvement. Therefore, they insist it should be kept, even if it makes the code extra convoluted for no reason at all.
And yes. Profiling is great. Often it is a surprise where most time is spent. Today there’s few excuses not to profile since most IDEs has a good enough profiler included.
Nice article. For the optimization related ones there’s a good rule of thumb: it’s not an optimization if you don’t measure an improvement.
That’s how DRY is described in Pragmatic Programmer, where DRY was first coined. They’re clear that just because code look similar, doesn’t necessarily mean it’s the same.
I agree with the first point. Always go for clarity over cleverness.
I somewhat disagree with the second point. Consistency is important. Stick with the same name when possible. But I think mixing camel case and snake case should be avoided. It can make the code less ”greppable” IMO, because now you need to remember which casing was used for each variable.
Kind of agree on the third point. I think flatness should be preferred when possible and when it makes sense. Easier to find the variables with the eyes rather than having to search through nested structures.
I can already hear Fromsoft fans say “it’s for lore reasons”, “it’s Miyazaki’s vision”, “git gud”, etc.
It’s a surprisingly good game even it’s just a clicker game based on HTML forms.
Elden Ring. Even after finishing the final boss there was so many areas I’ve not been to. And all those areas are unique - some with unique enemy types. It’s the game that dares to hide a secret area behind a secret area.
Without the Naughty Dog reveal I wouldn’t have remembered the trailer 10 seconds after it ended.
Everyone gets some sort of income, but wouldn’t companies just subside the income by raising their prices?
Not necessarily. Companies need to set prices they can compete with. Customers might just go to the competitor otherwise.
This is provided that there is competition. Monopolies can set the prices how they want, because there’s no competition.
Now the question has been asked and universe has no longer a purpose. The end stage of the universe is starting now.
It’s also deliberately poorly dubbed, which adds to the fun
You’re right
A favorite from this year is the trailer for Doom: Dark Ages. Excellent pacing. Weapons I’m waiting to get my hands on. It makes it clear how it’s going to set itself apart from the previous entries, and I’m hyped for it.
An all-time classic will forever be the first trailer for Zelda: Twilight Princess. At the time it was the right trailer for a new Zelda. People wanted a ”proper” Zelda after Wind Waker, and what they presented was just mind blowing. In the end I didn’t enjoy TP as much as I wanted, but that first trailer still gives me goose bumps. At least TP made me find a new appreciation for WW.
I’m at the point where I think I can engineer anything. But I also know that it takes effort and I ain’t gonna do that unless there’s a paycheck.
Optimizing CPU usage by 0.02% is something only the truly deranged do
Basically it’s just an optimization of a double nested for loop. It’s a way to avoid running the inner for loop when it is known there will be no hit.
This is useful when we for example want to find all product orders of customers in a particular country. The way we can do this is to first filter all customers by their country, and then match orders by the remaining customers. The matching step is the double for loop.
Something like this:
for order in orders: for customer in customers_in_country: if order.customer_id == customer.id: …Many orders won’t match a customer in the above query, so we want to single out these orders before we run the expensive inner for loop. The way they do it is to create a cache using a Bloom filter. I’d recommend looking it up, but it’s a probabilistic cache that’s fast and space efficient, at the cost of letting through some false positives. With this particular use case it’s ok to have some false positives. The worst thing that can happen is that the inner for loop is run more times than necessary.
The final code is something like this:
bloom_filter = create_bloom(customers_in_country) for order in orders: if bloom_filter.contains(order.customer_id): for customer in customers_in_country: if order.customer_id == customer.id: …
