Let me explain a little bit different way. My first run in with the idea was when I started using Ultra Recall for GTD, many years ago. https://www.kinook.com/UltraRecall/Manual/multilinking.png Ultra Recal is an

It is not knowledge classification. It is association (like this PDF file is associated with this project). But association can be used for classification (this PDF file is associated also with THAT topic). Which is exactly my point. Hierar

No, the intention is not to map it 1:1 to a hierarchical filesystem. My intention is to select a starting point, squint your eyes a little bit and then pretend it can be traversed from that point, the same you do when you search for a page

How do you traverse a symlink that points to one of its parent folders? How do you traverse a web of interlinked sites? Somehow Linux, Linux software, web browsers etc. are already able to deal with directed graphs.
337.
by lmilcin 5y ago
Or better idea. Use directed graphs. Directed graphs are strictly a superset of both tree and tag (set) functionality. Tags (sets) can be thought as a special case of directed graph. You make the tag a node in the graph and you make files a

I have been one of admins of a legal but student-operated network in a dorm with about 250 rooms. It was around 2000-2001 and it was 10BASE2 (with BNC connector). It was hell and heaven. On one side we had free, unrestricted couple hundred

Why not write a simple service that tracks various stats (like number of users, requests, etc.) as well as billed costs over time? You could then get various interesting stats in real time as well as some pretty useful alerting.

For these kinds of chips there is usually nothing the new process can offer other than higher development costs, higher production costs, longer cycle times, lower yields, higher noise levels and higher EMC susceptibility. A chip that fits

If you can point all that stuff out I will already be a little happier as an interviewer. Most people just say "no".

It is a tradeoff. With overcommit disabled, the program will fail in a more predictable way. Moreover, if it allocates the memory successfully nothing bad can happen to it later. So you have the option to allocate the memory right at the st

It is not. It is actually very useful and advantageous for many reasons. The disadvantage is the pretty shitty failure mode. But in practice, I have never seen an operating system that was not a toy that was able to reliably, gracefully han
344.
by lmilcin 5y ago
Yeah. And the issue is that the actual problem happens sometime later when the application actually tries to use that memory. So you replaced an error that is relatively simple to handle with something that is impossible to handle reliably.

Funny thing, you are right. I was thinking about something else I guess.

One of my interview questions starts with "Can a program allocate more memory than is physically available on the server?" Everybody gets this wrong (which is funny for a binary question) but it starts an interesting discussion th

Not the same thing. malloc() can tell everybody it has the memory but when push comes to shove the OS will have to admit overbooking.

Yes, that is exactly right. I am skipper on a small yacht, not a captain of a nuclear sub, but the reality is basically the same. In the end it is my job to make sure we don't do something that might endanger the ship and the crew. And

I think larger lesson here is that magic may look enticing, especially to the beginner, but it might cost more over long term than a little more involved but non-magical process. It is irritating to work with a system that from time to time

Stoichiometric mixture is only loosely connected to flamability. You can have a stoichiometric mixture that will not be flammable because both reagents would be in right proportions but very diluted in the inert gas. And a mixture that is v

Let me put my perspective on this. The answer is both yes, and no. Why no: Seriously, if you need certification to put your processes in order you are in a deep shit anyway. As an organization, you should be striving to continuously learn a

The problem is simple. Whatever you do, don't blindly implement something just because it is written in a book or an article. Agile is about focusing on constantly improving processes. Ask yourself, "Are the standups paying for th

How frequently do you test a new web framework with "10MB compressed JSONs"? On the other hand you can find a lot of benchmarks that use basically Hello World just to test your request response or some rather small request/re

It is interesting concept for a blog post but ruined by very inefficient implementation. I would expect orders of magnitude more work done on ~20W. Also parsing a compressed 10MB JSON seems like an unusual request. It would maybe be more fu
