I like Glider. It's just text and easy to navigate through comments


Because theres a snowball's chance in hell that will ever happen. Just build normal trains and expand the public transportation like every developed country on Earth.


Would the index number actually be smaller than the actual data?


It would average the same size as the actual data. Treating the pi bit sequence as random bits, and ignoring overlap effects, the probability that a given n bit sequence is the one you want is 1/2^n, so you need to try on average 2^n sequences to find the one you want, so the index to find it is typically of length n, up to some second order effects having to do with expectation of a log not being the log of an expectation.


You need both index and length, I guess. If concatenating both value is not enough to gain sufficient size shrink, you can always prefix a "number of times still needed to recursively de-index (repeat,start-point-index,size) concatenated triplets", and repeat until you match a desired size or lower.

I don’t know if there would be any logical issue with this approach. The only logistical difficulty I can figure out is computing enough decimals and search the pattern in it, but I guess that such a voluminous pre-computed approximation can greatly help.


No invertible function can map every non-negative integer to a lower or equal non-negative integer (no perfect compression), but you can have functions that compress everything we care about at the cost of increasing the size of things we don't care about. So the recursive de-indexing strategy has to sometimes fail and increase the cost (once you account for storing the prefix).


Is there some inductive proof of that? Or is that some conjuncture?

Actually any resources related to that point could be fun to explore


It's a classic application of the pigeonhole principle, the first on in this list:

I don't agree. Selling a gun to a hunter is not the same as selling a gun to a known child murderer. Both is "just" selling a gun but they are very different in practice.


You can't take responsibility for what someone will do with your product. This is insane. If someone buy your car, how can you make sure he will not use for kidnap someone?


Of course you can. We just sell cigarettes it’s not our fault problem of people smoke them and get sick?


Society is much better when we have individual freedom and responsibility, which includes the ability of people to make bad decisions.


And here “freedom” means you are forbidden from discussing certain topics at work?


Yes. The environment and time is controlled by your employer to maximize productivity for the business. You're free to do whatever you want on personal time, including not working for a company you don't like.

Usually people making your argument also say that private corporations can and should moderate speech. Do you support that? If so, then why do you disagree with workplaces banning topics?


Setting aside whether business can or should regulate employee speech: can you expand on how them doing so makes people more free?


You're misunderstanding the concept. Individual freedom means you're free to make your own choices and then take responsibility for those choices. This freedom is protected by your rights granted by the state.

Corporations setting workplace rules have no impact on your freedoms. You're free to work there or quit, or suffer the consequences of breaking their rules.


People make dumb things like smoking. We already know that prohibition doesn't work. Putting warnings in the cigarets doesn't work either. So, the next thing would be the seller give a speech about how bad cigarets its for each sale?


If you take a look at the history of smoking, it's very clear that education and taxes DO work.


Absolutely that yes. Cigarette salesmen are performing a valuable service.


Yes you can, and this is why know-your-customer laws exist. This isnt black and white, and depends on the kind of transaction. But if I’m selling cars, and someone comes in looking shifty, and says they want a big SUV to mow people down with, then claiming “I’m just a merchant with no responsibility on end use” is honestly weak bullshit.


> looking shifty

How do you decide this? Your intuition? The clothes someone is using? The way his talk?


If seller offers guns to general public (e.g. gun shop) and child murderer does not have restriction on gun ownership as a part of their sentence, then not selling gun is not a political action, it is an extra-judicial punishment.


Yes, but this distinction doesn’t require a corporate policy to implement. One transaction is legal and the other is not.


Would you like to mandate background checks for every potential customer?


ya, one would be illegal


Does your view change if the gun was sold to a republican vs a democrat? Or a communist?


I'm pretty sure most thinkpads have case intrustion detection. It's callled "Bottom Cover Tamper Access Detection" in BIOS.


I've heard some good things about Omnifocus but it's Apple exclusive so guess I'll never get to try it out.


There’s a relatively new web-based version.


I was excited hearing that. But seeing the pricing.. yikes. The web subscription for 50$/year requires a iOS or mac standalone license for 50$ one-time.

If I would be able to use the iOS/Mac native app, I wouldn't even need the web version....

I understand that focusing on Apple(OS features) is what makes these apps so great. But it's sad to not beeing able to use these apps, even when they finally offer a web version.


Unless they've made huge strides lately, it's nowhere near parity and leaves out most of the differentiating features.


Yes, this is the single app that locks me into Apple's platform these days.


I'm similar. I have my own Eisenhoweresque productivity system for triage and prioritization implemented across ~10 perspectives, etc. I've been trying to adapt myself back to mainstream reality that Todoist or TickTick could handle for portability's sake but so far haven't succeeded. I like my own system, predictably enough.

The UI is beyond idiosyncratic, but the only web package I've found with enough power to replicate all my OmniFocus perspectives is The Amazing Marvin.

It is incredibly configurable across any number of productivity systems, and the query language for saved searches (aka perspectives) is straight up RPN with a metric crapload of task matchers and unlimited stack depth. Tag groups can be active parts of the UI that turn into task entry dropdowns, so you can make your OmniFocus tag system into actual user interface with exclusive tags. You can't be both UI and NI for example, so you can create an Urgent/Important exclusive group and make it a dropdown. It's stunningly effective in these ways and gives you so much more flexibility than Omni.

The only problem is literally every part of the app has different key mappings and UI affordances. It looks like it was cobbled together homegrown feature by feature and the design unfortunately really does show it.

It's worth a shot, but it does make OmniFocus look downright polished UI-wise. But man, the power of that system for configuration...super impressive.


For myself, it is OmniGraffle. Now I just keep an older Macbook Air around solely for diagramming.


Ahaha yes. I once run hackintosh in a VM, just to draw diagrams for an important homework.


it is absolutely rape.


yeah but that might not always work. there are evidence against him but he will never be proven guilty in a court because of unrelated practical reasons. that don't make innocent either.


Full asset cook on our (big) UE4 project can use up ~150GB of RAM


But why use a mac pro for that? It's not like UE4 only runs on mac or even has an advantage running on mac.
