Readit NewsIt just takes time for free software to match commercial offering at first, but eventually it surpasses them (too many example to list) for 90% of the uses.
If it let me cancel my Bloomberg subscription, why not?
All I want is reddit + twitter firehose sentiment mining, accurate plot of basic (EURUSD, wood futures) and not so basic (VIX) things.
I do not need to keep track of cargo ships on a map.
Not everyone is up to writing textbooks and compilers all day.
You are waiting for death. That is the only thing wrong.
Color me surprised!
1. Gzip is not a suitable compressor for this use case, because it's limited to a 32KB window. So the input can only be correlated with the last 32KB of the reference texts.
2. You can save a great deal in computation by avoiding recompressing the reference texts over and over and over. Some compression algorithms support checkpointing the compression state so that it can be resumed from that point repeatedly ("dictionary-based compression", which is a distinct capability from just streaming compression, which generally can only be continued once).
I would personally shill for using Zstandard [0] instead for this purpose. Although I should disclose my bias: I'm a developer of Zstd. A few salient facts:
1. Zstd supports very large windows (up to 128MB, or up to 2GB in long mode).
2. Zstd is much faster than zlib.
3. Zstd has well-developed support for dictionary-based compression.
4. Additionally, it has a dictionary trainer that can reduce a corpus of reference documents to a compact summary document that aims to capture as much of the content as possible of the reference corpus. [1]
5. It has (more than one) python binding available. [2][3]

Is it some kind of memoization?
The last release wasn't in February, it was just last week! <https://metacpan.org/release/ETJ/PDL-2.050>.
I agree with many of the commenters here that Python has a lot of great libraries and is a major player for scientific computing these days. I also code in Python from time to time, but I prefer the OO modelling and language flexibility features of Perl.
Speaking for myself and not the other PDL devs, I don't think this is an issue for Perl-using scientists as Perl can actually call Python code quite easily using Inline::Python. In the future I will be working on interoperability between the two better specifically for NumPy / Pandas. This is also the path being taken by Julia and R.
Do you have a tutorial and some examples? If not, could you write one?
I sometimes deploy perl code at large scale for financial computing where only performance matters: with XS the overhead is low while gaining language flexibility.
Even in 2021, this is usually faster than alternatives by orders of magnitude.
PDL could be a good addition to our toolset for specific workloads.
Some of this information may be urgently needed at a time when the patient is not capable of giving informed consent for its disclosure or does not have it immediately available.
Some of the information may be vital to the future healthcare of the patient and would cause serious harm to them if it were lost.
And in more of a more morally grey area, some information might be harmful to the patient if they had it. For example, consider the implications of bluntly disclosing various mental health diagnoses to someone who doesn't fully understand what they mean and whose condition means they won't necessarily respond rationally or beneficially to the information.
In this case, having the records kept locally by exactly one organisation that is run by medical professionals who are bound by strong professional ethics seems like a reasonable policy.
Only if you have a paternalistic view
> Some of this information may be urgently needed at a time when the patient is not capable of giving informed consent for its disclosure or does not have it immediately available.
What if I accept the risk I may die due to bad luck/odd circumstances to still refuse the information being handled out by anyone but me?
> Some of the information may be vital to the future healthcare of the patient and would cause serious harm to them if it were lost.
Likewise, what if I accept future risks? I have more skin in the game from losing my records than an hospital losing them anyway.
> And in more of a more morally grey area, some information might be harmful to the patient if they had it.
Then what about I refuse having the information, in exchange of the information also being unavailable to anyone else?
Many people here seem to have the view "more information is good" but not collecting it in the first place seems better to me.
Hence I do no healthcare in the US, only in SE Asia where most services are available in English and Chinese anyway.
She inspired me and other in her boldness
> Maybe she is. I see no grace in her performance though. Maybe I'm too used watching Soviet Bloc gymnastics. Isn't this artistic gymnastics? I see no artisticism in her performance, just routine - it's like a robot doing it, but failing to land properly
Your lack of interest in pushing the boundaries or rejecting pre established rules (Who said gymnastics should only be about art? Why do you think soviet block country must forever be the model?) strikes me as dull and classicist.
You would be very happy in China mainland, where you have one model to obey and follow, coming from the top down, with no room for inspiration or breaking the mold.
Your fixation on "great man" view of history, in which only those who affect society on a grand scale matter, belongs in the last century, as does your reductionist view that societies "progress" along some linear axis of "good" or "bad." Everyone affects society, everyone matters, and society moves in countless directions at once.
Nevertheless.
However unimportant you may consider Simone Biles, the fact still remains that she's accomplished far more than you likely ever have or will. So apply your own rubric and find a bit of humility. She has achieved master status in her art. She has doubtless inspired generations of gymnasts with a lifetime of practice, effort and skill, and made an indelible mark on her field. She's the best in the world at what she does. What have you done, Nikolay?
...that's a rhetorical question, I don't actually care.
I love your take. It makes me happy to find the rare soul on HN who gets it.
However, if I was a Taiwanese trader or market maker, I'd likely pay Taiwanese exchange fees to get access to richer, real-time data (specifically, non-delayed quotes and more market depth.)
I can get this access in under 5 seconds by opting into the desired exchange privileges under EXC<GO> or most likely just pinging my Bloomberg rep. If I remember correctly, I have to log out and back in for the new permissions to permeate my terminal. The cool thing is that all functions automatically leverage the highest level of subscribed data.
Whether I need to jump through more procurement hoops than that depends on where I work. If I am in a small hedge fund, I can just "do this" and if I am in a big firm, we likely already have this data subscribed for.
One of the many reasons Bloomberg exists and continues to be immensely valuable is that it prevents you from having to mess around with individual exchange permissions and data in a one-off way. And don't get me started on normalizing data across exchanges - the fact that Bloomberg does that for you is worth the price alone.

Because there is a marketplace. If Gamestonk is successful, there will be a marketplace for low latency feed + commercial support to configure them for you.
