I'm working in the IIoT domain too. Your workflow is interesting towards the end. Any particular reason, why you don't write it to some db like Timescale or Influx at the end without any prometheus conversion?
Victoria Metrics is a Prometheus compatible time series database and was being used before I joined the company. I haven’t had any issues with it so I didn’t see a reason to pull it from our stack. Are you saying Timescale or Influx can natively ingest MQTT messages?
Similar to your mqtt converter you can make them ingest via Kafka or some other adapter in between. EMQX broker can directly write into TSDB but did not research into others whether they can or not.
Not the OTEL "telemetry" but sensors sending measurements from the field "telemetry". IT tech is, as usual, stealing perfectly defined engineering words and making them something else.
TimescaleDB is perfect if you also have relational data that you need to join with field data to the point that there no pros of using anything else for this use case, say you have 100000+ sensors and you need to group them by the customer site relations while aggregating per day statistics.
NumPy has no Fortran code, for quite a long time now. SciPy has and it is being rewritten. What you mention is the ufunc machinery underneath which is all C. NumPy also has SIMD support (albeit limited to certain functions). BLAS is also C/Assembly but only LAPACK is F77 (which is too much code to be rewritten).
This does not mean Fortran is bad (obligatory disclaimer for Fortran fans).
Also, Fortran has progressed immensely since F77 days. (I actually wrote some F77 code back in the day, when it was already ancient.) C has also progressed quite a bit since K&R days, but, to my mind, not nearly as much.
right, the problem for scipy developers I believe is that not enough of them know fortran, whereas C knowledge is necessary to hack on CPython native extensions.
I’m not going to lie, algebra wasn’t my cup of tea for a long time. Whenever you have a naive set of people commenting on a thread, my theory is that there is a category of folks who always take it too far leading to people feeling left out. An excluded middle if you will. I say education is at the root of the problem, and blame the state machine for that.
Same experience for me. I was able to buy my first drumset from the money I got for making a PHP+MySQL+HTML website for someone (also done all in notepad). I did not know anything about computers but I needed to buy a drumset. And that page actually got me going about how HTML works.
I still remember their animations about car differential which were magical.
And your point other than a personal attack on my feelings of self worth (in direct violation of not just the rules but the ethos of Hacker News)?
Anatolia is a location, not a culture. This is an article on cultural changes. Using Anatolia, a large region of land, as a descriptor for culture seems weird an needlessly imprecise in an archeological/anthropological sense for an article talking about an impact on cultures (what cultures?). Why would someone use 'Greek-style athletic contests' when 'greek athletic contests' is a more accurate/direct/correct description?
It is totally valid to say 'I don't like the current trend of twisting words/obfuscating, it sucks and makes me defensive reading the article, and the use of this less descriptive subsubstition and zero direct mention triggered that distrust'. Or are you saying I should just brainlessly consume everything I read online and to do otherwise is somehow not manly?
You should read more carefully to start with before accusing everything you see that does not fit into your narrative.
requiring n time the word Greek until you are satisfied is a you problem. I don't care enough about you to attack you personally. If you read more on these you would not get stuck in these accounting problems.
Why lead with more personally directed comments? Instead help me understand how a geographic area that has changed cultures is the best way to refer to the culture being talked about? At least refer to XYZ/ABC/123 populated Anatolia or something (I get it can get somewhat blurry in that area and time). I don't think the linguistic root of the geographic area's name gives all that much context and think they cop out because interdisciplinary politics of if ABC or XYZ is Greek but they then leave unread people like myself uninformed who they are talking about.
They went into enough specifics to name individual cities but I admit I don't always know which cultures lived in which cities in which time periods off the top of my head. I remember just enough that calling it 'Greek style' for the Greek cities they named seemed wrong to me. I think it's more informative when articles gives at least a little insight to unread people like me on which populations they are referring to, not just geography:
This is a bit of a strange presentation of stability but I liked it. I don't agree with the phase margin absence in the other comment but it would have been much clearer if the author chose to present it once via a Nyquist plot, then stuck with the magnitude plots which would clarify what we are talking about. It is also very welcome clarity to see that we are not using the weird dB unit in Bode plots.
For those who are not related to the field, what the reported subject here (and destabilizing effect of the negative feedback) is fixed by Black to remedy amp ringing, led to Bell labs, develop frequency domain techniques later analyzed by Nyquist and Bode (also seniors in Bell labs) then made western control theory kick off (then united with the Soviet techniques) and today everybody losing their mind about boosters coming back to base with SpaceX (which was already done a few times historically decades ago).
You are thinking in western grouping of tenses on a verb conjugation of a different language. It is not the mood that is not inferred here. It is the property of the verb. Verb itself can be used to communicate the same information with a single word "Gitmisim" just as valid ("I apparently went there"). So where is the tense of a single word if it does not have tense in it? How do turkish people communicate without a tense using a single word just with the mood?
I'm not entirely following your argument. If your point is that it's a "single word", that doesn't really matter. That's just because Turkish is a synthetic language (uses morphology to convey info instead of separate words). Latin is famously a synthetic language and it still has concepts of mood, tense, and aspect.
Frankly, you don't have to take my word for it. I suggest doing some research on how mood and tense work in linguistics. It's not clear to me that you understand what these terms actually mean. Maybe I'm wrong.
I think you are also giving yourself too much credit on the separability of tense and mood and if it does not fit into your mental model you are discarding all other options. You can do the same research yourself. Mood and tense are not always separable as you might think. Morphology is a red herring here. It clearly transmits the essential time information and also adds mood no-confirm structure on top. Hence if you don't consider that as a tense, then I have the same suspicion about your knowledge and obviously I might be also wrong.
I am not suggesting that you cannot convey both mood and tense information with the same pattern. I agree with that, and I already made that point in my English imperative example. I also agree that moods can restrict which tenses you can express, sometimes restricting it to only one possible tense (as with Turkish inferential).
The point I am making, is that by the definition of mood, "inferential" simply has to be a mood. The point of using it is to suggest a particular relationship with reality ("I didn't see this, but I heard it second-hand"). That's modality, i.e. mood. It also happens to restrict the temporality of the verb to the past.
> It clearly transmits the essential time information and also adds mood no-confirm structure on top.
What you seem to be referring to here is the actual vocal pattern that you attach to a verb root to signify gossip. Of course, word endings can convey both tense and mood, just as they can convey both gender and number. But they are still separate concepts.
As a former drummer who bashed way too many Chinas without proper ear protection, I had some scary tinnitus for quite a while. My advice;
- First make sure that the frequency is not dancing around. If it is then probably it is one of those things your brain making up then it is relatively easier to fool yourself back again. Check it when it happens https://audionotch.com/app/tune/ (disclaimer I am not related to website, just first google result).
- If it is constant then try to counter it with noise especially when trying to sleep. Just give yourself one of those nice YouTube colored-noise videos like this one https://www.youtube.com/watch?v=8SHf6wmX5MU
- Avoid in-ears altogether, especially the bass-boost ones make sure that it does not fit airtight. More bass does not mean you pulsate your ear-canal with an airgun. If you want proper bass sound, invest in hi-fi stereo and listen to it in a good room.
- As mentioned, distract yourself. Even if it is chronic and actually has a pathological cause, the brain finds a way to cope with it, like the glasses on your nose not noticing the weight.
