I think you've got this backwards. You don't need to understand the notation, you need to understand the math. If you don't understand the notation then you probably don't understand the math in the first place so learning notation won't help. Learning how a matrix is written is useless without understanding what a matrix is.

You need to find out exactly what type of math is used in the paper and learn that. Learning notation will come along with that. If you're interested in machine learning then you should probably start with:

* Proofs and logic (a general requirement to understanding math)
* Linear algebra
* Statistics
* Some multi-variable calculus
Is that any more true (other than subjectively)?

In my opinion, using RMDBS as source of truth makes more sense, because these systems were optimised for reliability, durability & data retention.

To be completely honest, some have drunk the proverbial Confluent koolaid, with kafka being the hammer to hit all nails.

I just want to communicate the risks & tradeoffs with taking this approach. Problem is, the theory sort-of holds up, if configured correctly, kafka should be as reliable/durable as PG/SqlServer/MySQL cluster. But I can't find any material on companies experience running kafka this way, I.e. 'we ran this setup for a year in prod, one of our brokers disks got corrupted, but we were able to get back with no data loss, via X,Y,Z.' or 'we couldn't recover and had to accept data loss'.

EDIT: in short, are the claims made by this article reliable: https://www.confluent.io/blog/okay-store-data-apache-kafka/
It ensures you have a plug-in manager installed, but it won't install it for you, right? I know that might seem like a minor nit, but if package management is considered an essential part of Vim, I'm of the mindset that it should work out of the box.

That said, Amp doesn't have plug-in support at the moment, so it's a little unfair for me to judge Vim on that front. But if it did, the package management portion would be baked in so that you'd only need to pull your configuration file and Amp would handle the rest. :)

This is really screwed up. "Everything is worth what its purchaser will pay for it" is deeply immoral when applied to life and limb. I can hardly understand how a democratic society can accept a system like this.

I mean, can you even imagine other areas of life where every person you purchase from attempts to screw you over by demanding 2x-10x of the reasonable fee unless you had the information to be aware of it? It would be impossible, because everyone would just take their business somewhere else.

But you can't exactly say "oh, I'm not willing to pay my life savings for this, I'll just take this 3 months prematurely born baby to the shop across the street, or maybe get it done in six months time instead, when it's more convenient.".
That was 50 years ago, and the barriers to enter the programming profession were much lower. I'm sure that I couldn't do it today.
This is incredible advice I really appreciate it.
It would be nice if this were orderable by "what year it was released"/"what year it was shuttered", naeemnur. Would also be good to link to the official "shut down" notice, which presumably you had to consult to get the date right, so having a link that people can follow to start their own web trawl would be quite useful.

Listen carefully to what the people in the company are telling you: how things work, who are the people who can get things done, etc. (For some of the political stuff, you may have to read between the lines.) Don't try to stick your two cents in to impress them with how much you know - just listen to what they have to say.

Also, people like it when you actually listen to what they have to say, so you might end up making some friends this way.

To get promoted, you'll need to have a good relationship with your direct manager, since you're not likely to get promoted unless he or she says good things about you.

It will only occur if everything is so irrevocably on fire that you need to debug a lot of code anyway, at which point the error message is useless.

Specifically, the branch is only reachable if the PID is not what was expected, or the location that the macro was supposed to longjmp to is not set, which would be fatal defects.

TLDR: his boss at a mall coffee shop was great and being a teen, he loved working for pocket cash on black fridays. i think the author has it all wrong and is mistaking his nostalgia and youth experience for the reality of modern day black friday. the fact he liked working is not a consequence of a particularly good boss.

It's since been discovered that Polybius is a hoax perpetrated by the maintainer of coinop.org, an arcade-machine info site, in 2000 or so in order to drive traffic to his site.

Poly Play may have indeed been an influence in the creation of the hoax.
Vim has very simple highlighting, and doesn't support symbol jump; that's why ctags is an external dependency for that behaviour.

As for a file finder, I'm curious how you can use a separate tab to open that in the current instance of Vim? From when I'd last used it, most folks were using Ctrl-P to solve that problem, and usually with an external indexer like fzf or ag.
>Unlike steel or aluminium, carbon fibre doesn’t work harden so, as long as you don’t crash it, it will be MORE durable than steel.

Steel is almost perfectly elastic below its fatigue limit. It never fails for stress underneath this, since the elastic motion doesn't generate new dislocations or anything. It is true that aluminum has no lower fatigue limit, but outside of crashes, this occurs so slowly as to be meaningless on human timescales.

>Also because carbon frames are layed up by hand, you can can have different properties vertically vs laterally. So stiff side to side but with vertical flex at the bottom bracket ...or anything else you want.

That is 100% not true. Bike frames are all highly stiff vertically because of the diamond tube shape. There is no practical bikeframe of any material that has non-negligible vertical compliance. That is just marketing fluff.

I think it’s important to understand what our objective is.

Reading these comments comparing birds and aeroplanes is nonsense since they both have very different flight behaviours and objectives. Birds’ wings flap for agility to avoid predators. They have brains which is half reflex and allows them to regulate their bodies. Planes don’t have predators and don’t need cognition.

If our objective is to solve a business problem, machine learning is great for specific tasks and can achieve superhuman results in some cases. We don’t need much neuroscience here.

But if our objective is AGI, it gets interesting because it is very far from current machine learning / deep learning / reinforcement learning. It’s hard to put a definition on AGI at all. What do we want to achieve? To replicate the human brain, of course we need neuroscience. To replicate intelligence without designing the components for bodily function will need an approach which looks at brain circuitry and function but is implemented with a good level of abstraction.

I believe we know a lot more about the brain than the public thinks. Read Cell Neuron and Nature Neuroscience journals and clinical encyclopaedias to get an understanding. I don’t think we should be replicating things on the neuron level but at a more abstract level of neuronal dynamics, neuronal populations and networks with a focus on understanding the developmental biology of the first few years of human life where learning really happens.
Even the name percolates down the sands of time. The fifth Mughal emperor and builder of the Taj Mahal took the name "Shahjahan," i.e., King of the World. Like Ceasar becoming Kaiser, etymology recapitulates history.
I live in Gabor Maté's hometown of Vancouver, where he has been a pioneer in transforming how the medical profession and government deals with the addiction epidemic affecting the city. Looking out my office window right now, I can see the clinic which is pioneering opioid replacement therapy, in which addicts who have failed all other avenues of addictions treatment are injected regularly with hydromorphone and diacetylmorphine. Without Maté's courageous work in this community, the research underpinning this therapy would potentially not have occurred.

I think that’s how everybody does it with stuff that’s new to them.

After enough slow progress (“one page per day” can easily be speed reading), parts of what you are reading become what mathematicians call ‘trivial’, and your reading speed of similar texts increases.

I think there’s an analogy with ‘reading’ a chess position. If you watch the ongoing Carlson-Caruana match on https://youtube.com/watch?v=DgvqBjrusIA, you’ll notice that the commenters can easily go through three or four variants in a minute, and call one position an obvious draw, another clearly winning, etc. The reason they can do that is that they have looked at thousands of similar positions, and remember the essential parts of them.
Appreciate that!
Regarding Alexa, the sargonsays app does store the phonetic pronunciations so that you could sound it out by saying the word / phrase aloud. To your point though, Alexa won't know how to sound it out correctly. For that reason, the most popular terms have audio recordings already so I'll try to have Alexa just play the recording. I've had some success in the past getting local Assyrian organizations and churches to help with the manual effort of audio recordings.

I didn't buy single one since I have seen many youtube videos, all seem to have latency (yep, HID device). By latency I mean, when you throw steer, you can see it reflects about 1/3 second to the gameplay. It is very hard to blame slowest part, probably the game itself, but I really wish that would be solved.

> If the qualifications on their resume fit your requirements, just bring them in!

It's not uncommon for there to be a huge mismatch between what the resume says and how the candidate interviews. Especially since it's well-known that resumes are programmatically screened nowadays, candidates feel pressured to play buzzword bingo with their resumes.

A quick phone screen or take-home is far more humane than bringing them on-site for 6 hours and having them flail miserably in the interview because of the resume problem.

I also don't see how they could nail an on-site interview but fail a phone screen. It seems like the skillset there is roughly equivalent, regardless of whether you agree with that skillset being indicative of on-the-job performance.

I actually used HTM in a project a few years back.

I had a 360x180 sphere of values, and I needed to rotate the sphere in some combination of translations. I did this by converting the az/el/value triplets to Cartesian XYZ and multiplying by a rotation matrix.

However, when I tried to convert the translated values back to a rotated az/el/value result, the results broke due to what was effectively lat/lon narrowing (ie, 1x1-degree cells are smaller nearer the "poles", so the rotations didn't map evenly).

After research, I settled on using HTM. I was able to borrow the C code from some MySQL extension that implemented HTM (looks like it's at https://github.com/smonkewitz/scisql ), then use that math to more reliably convert the rotated values back to an appropriate az/el/value result.

Still one of the neatest problems I ever solved.

Some things that help me a lot, in order of helpfulness (for me):

* Read formulae aloud, using natural languages for symbol names (it is not "sigma of k from i to j", it is a "summation of terms with k from i to j").

* Look at the proofs/construction of these formula and understand them.

* Look at translations of the formulae (applied physics textbooks, more often program code); sometimes it helps to work your way back to the formula from a starting point you are more comfortable with.

* Understand that making up symbol meanings ad hoc is one of the perks of mathematicians - you can find fights within a single math department on how notation should be.
Yes they do.

>So the author of the article is upset that the astronomer in question never thought about the correlation between reduced solar activity and a mini-ice age until hearing the connection from the media. After she decides that, yes, "We didn’t mention anything about the weather change, but I would have to agree that possibly you can expect it [a mini ice age]." He determines that a) Zharkova doesn't know what she believes and b) even if she did, her peer-reviewed literature is inferior to his own and she obviously doesn't what she's talking about.

If a mathematician and astrophysicist pushing their theory about the inner working of the sun has only just thought about potential impacts on climatology due to sudden media excitement, then they have probably just skimmed it compared to actual climatologists. There is already existing research into the effects of a grand minimum on climate change, is not as though climatologists aren't going to think to look into that. Here's a paper from 2010;

"On the effect of a new grand minimum of solar activity on the future climate on Earth"

http://www.pik-potsdam.de/%7Estefan/Publications/Journals/fe...

Here's the summary -

"In summary, global mean temperatures in the year 2100 would most likely be diminished by about 0.1°C. Even taking into account all uncertainties in the temperature re-construction, the forcings, and the model physics, the overall uncertainty is estimated to be at most a factor of 3, so the offset should not be larger than 0.3°C. Comparing this to the 3.7°C and 4.5°C temperature rise relative to 1961 1990 until the end of the century under the IPCC A1B and A2 emission scenarios, respectively, a new Maunder type solar activity minimum cannot offset the global warming caused by human greenhouse gas emissions. Moreover, any offset of global warming due to a grand minimum of solar activity would be merely a temporary effect, since the distinct solar minima during the last millennium typically lasted for only several decades or a century at most."

Also, the scientist in question says that at best, "the Sun buys us time to stop these carbon emissions", so she is still worrying about the climate getting hotter.
This seems like a loophole that one could exploit to make a lot of money. Get a mortgage and buy a million dollar home. Stop making your payments. Wait for the bank to sell your delinquent debt, and buy it for $500k (or whatever the discount happens to be). You now own a million dollar home for a fraction of the price.
Google Wave died because it was a nice hipster idea that never came close to meeting the basic requirements for a corporate office, which was its primary audience. While Google completely failed to realize why this was an obvious and immediate failure Atlassian didn't miss a beat and took all of that marketshare.
God yes, I will miss Inbox hard. I have started trying out Spark, and it's sort of ok but there's really nothing out there with such a tight focus as Inbox. Gmail on the web is just awful, and perhaps that was one of Inbox's greatest strengths - it was fast and bloat-free where Gmail is decidedly not.
Indeed. I was thinking that the question is in some ways like asking "How can I understand the chemical symbols used in these equations". One could perhaps memorise that 'Na' is Sodium and H is Hydrogen but without knowing what they are and how they behave etc. an equation in isolation is meaningless and won't help to understand the reaction.
Look anyone that thinks their is a linear relationship between steady state temperate and heating has no idea what they are talking about. “A 2015 study looked at a 2 watts per square meter decrease causing a 0.13-degree celsius effect. A four times larger effect would be 0.5-degree celsius.”

Black body radiation for example is t^4 on the Kelvin scale. Which is why Mars sees temperatures as high as 20C even though it gets 590 watts per square metre vs 1,361 watts per square metre for Earth. Note our moons are a better direct comparison as they don’t have any atmosphere.
I liked google wave and I think it was a good example of a product that was ahead of its time.
I was just like you. Here's what I did.

1. Picked up a High School Algebra Book. Read from beginning to end and did all exercises.

2. Repeat #1 for Algebra 2, Statistics, Geometry and Calculus. (Really helpful for learning those topics fast was Khan Academy).

3. Did MIT Opencourseware's Calculus and Linear Algebra Courses w/the books and exercises.

Now, this took me about 2 years maybe you can get it done quicker, you're at a level where you can pretty much pick up any book, I think I picked up Elements of Statistical Learning, and actually start parsing and understanding what the formulas mean.

One thing I always do is tear apart formulas and equations and play with little parts of them to see how the parts interact with one another and behave under specific conditions, this has really helped my understanding of all kinds of concepts from Pearson's R to Softmax.
Network effects drove FB growth.

My friends were posting interesting stuff on FB, so I needed to join FB. Then my friends started posting stuff twice an hour from their phone, so I needed to check FB twice an hour from my phone.

Reverse network effects undo that growth.

First slowly, then seemingly all at once.

My most influential and interesting friends rarely post on FB anymore. Most of my ordinary friends are still there, but they only post once a week or once a month.

So I've deleted the FB app from my phone and now I check it a couple times a week from my laptop instead of a couple times an hour from my phone.

It's like Gresham's Law for social networks. Bad actors drive out good actors.

A falling signal-to-noise ratio is a vicious cycle that drives out signal and attracts more noise.

FB overreached in driving engagement, and it's backfired spectacularly. The FB brand is damaged and young people are embarrassed to use it.

Reverse network effects will remorselessly undo what network effects originally built.
one of the justifications for higher US health care costs, especially pharmaceuticals, is that US companies are developing expensive, world-leading treatments which benefit the entire globe.

and yet, i see stories like this and wonder if the US is really all that far ahead. i also wonder how countries like Japan, with a nationalized health care service, fund and bring these treatments to patients at all.
There's sort of an uncanny valley sort of situation, in my experience (as an anglophone canadian with the french of a 3-4 year old): If you're clearly a foreign visitor, and you're speaking bad french, it's often appreciated and maybe found slightly charming. But once you get to the point where your french is reasonably good, but you have an obvious accent, then (some) people (might, sometimes) be more inclined to be a bit snooty about it.
This answer matches my experiences very closely. When you feel you brain begging you to gloss over the equation and move on - that's a red flag that you need to slow down, exercise discipline over your concentration, and figure out what's going on. It might take a few days for the intuition to settle. Personally I've known it to take a couple of years.

edit: patience, self-forgiveness, and a willingness to accept frustration are important traits. You might spend a whole week banging your head against the wall, feeling like you're making no progress, and then one day everything falls beautifully into place. That doesn't mean you did something correctly on the final day - it means you did everything correctly for the whole week before. Don't view a difficult and unrewarding day as wasted time. You're building something very difficult and that takes a bewildering amount of time.
I don't disagree, it is always a question of degree. One party sees a 'scam', the other a failure of the first party to do more diligence. Some see separating poorly informed people from their money as a business, other see it as an injustice that needs to be corrected.
