If you are just a junior dev then it may be unnatural for companies to see 4 years of experience in your CV. They probably expect you to be a middle dev given the number of years in the field.

And the most important thing: companies generally tend to expect you to bring the value from month 1. Many of them are scared to death by the prospect of an extensive training for someone who may or may not be a good fit in the long run.
This is great advice. Thank you!
I really wish they could commit to shipping the 1080p screen on the 11” model. I’d pull the trigger tomorrow. But as far as I know, there’s still no guarantee if you’ll get the 1920x1080 or the 1366x768 display. That’s a dealbreaker for me.
Ask HN: What is exactly the role of Partner Technology Manager?
I am a senior developer who mainly works in Microsoft stack. Last day I got an mail from a recruiter for the post of Partner Technology Manager in a top Internet company. I checked the job description and did a bit of googling, but still not clear about the role. It'll be great if someone could provide the relevant information.
Thanks.
I care. One of my worst slow system experiences is my "new" Xfinity X1 "Entertainment System." Latency to remote control button press is on the order of a second or more. Worse than that, it will put prompts up on screen and not be ready for the input. For example, when I finish watching a recorded program it puts op a "Delete" prompt. If O press the OK button when this prompt appears, nothing happens. I have to wait a second or two and press the OK button again. When I open the list of recorded programs it can take from 2-4 (or more) seconds to display anything. The delays are long enough that I am often left wondering if it registered a button press or if I need to press again. I have to wait at a minimum 4-5 seconds to see if the system is catching up or if I need to repeat an action.
It's a constant irritation when using the system.
It baffles me that their flagship product is so non-performant. I guess that when you have no real competition there is no motivation to produce a better system.

This comment disputes the assumption that the quasar objects are only solar system sized as described in the original article.

>> Basically if an object is changing brightness, it can’t do that at a rate faster than the time it takes one side of the object to know what the other side is doing.

However, even this portion of the comment referenced is making an assumption that there has to be communication between the two sides. There is no requirement for such to actually occur, particularly if the effect is initiated at the central point and effects propagate outward. So if the assumption that quasars are black holes with accretion disks is incorrect, then the assumptions underlying the referenced comment can be completely irrelevant.

The claim is "5V 1500mAh" or 7.5Wh, which does seem entirely plausible in a device that size. (iphone x battery is quoted by wikipedia at 10.35Wh)

Compare to this totally existing product, 2200mAh in a volume of 25mm x 91mm x 25mm https://www.adafruit.com/product/1959

A drawing in the indiegogo page shows 73mm x 27mm, and maybe another image shows 11mm thick but it's hard to say. If so their design has to pack "just" 2x the energy density of a low end product. It might take care in design, but it's not impossible by an order of magnitude like some of these crowdfunding pipe dreams.

Show HN: Oyster Alerts is live and looking for testers in London, England
Hi everybody,

I am happy to share my latest side project in the hope of gaining some value first users and feedback.

If you use railways in London you will (or maybe not) be aware of the concept of "incomplete journeys". If you forget to tap in/out of a station with your travel card you will get charged the maximum fare. To rectify this you are required to manually log in to the TFL website and check for a refund. I find that awkward and time consuming.

I decided to built Oyster Alerts to check for incomplete journeys and thought you might also find it useful.

The site is very much an MVP now but does function and you will be alerted of incomplete fares.

It would be awesome if you could check it out and give any feedback.. http://oysteralerts.com

Thank you

I think it's totally doable, but you need two important things

1) a good exit process
2) a good promotion process

1 brings serious culture issues/questions with it. See horror stories from people who went to grad school in the 80s and 90s where year two cut rates were 50% or worse. I don't know how you deal with this, but it will certainly deeply affect your work environment.

2 is easy on the face, but requires huge buy in. Realistically you're looking at a 2-10x increase in this person's compensation over a very short time frame or you'll lose your training investment as they jump ship.

Meta: I opened this on mobile in a background tab and was quite surprised that my browser (Chrome on iOS) forcibly switched tabs to focus on the new tab. It seems it was because the site uses an alert to say "can't receive input on mobile". I guess this is the browser's default behaviour but seems like something that could be completely abused by spammers/advertisers.

Unfortunately, the two theories, while both being extremely successful and accurate in their predictions, are incompatible with one another. Quantum Field Theory has successfully combined Quantum Mechanics with Special Relativity, but that is all.

Psychology is different than other "hard" sciences.

I only say "results _may_ no longer be valid" and I'd say this study proves that.

If you go deep enough into the mind to the point where social environment no longer influences the behavior you may be getting closer to biology than psychology but point taken.

FDVS was written in 1942 when Halmos had just gotten his Ph.D. from J. Doob, author of Stochastic Processes in my list, at U. Illinois, and was an assistant to John von Neumann at the Institute of Advanced Study in Princeton.

IIRC Hilbert space was a von Neumann idea: It is first, just a definition -- complete inner product (dot product in much of physics and engineering) space. But the good stuff is (1) importance of the examples and (2) the theorems that show the consequences, e.g., in Fourier theory.

Well, the vector spaces of most interest in linear algebra are actually (don't tell anyone) finite dimensional Hilbert spaces. So, one role of FDVS is to provide a text on linear algebra that is also an introduction to Hilbert space, that is, that tries to use ideas that work in any Hilbert space to get the basic results in linear algebra.

The treatment of self-adjoint transformations and spectral theory are likely the most influenced by this role.

This role is accomplished so well that sometimes physics students starting on quantum mechanics are advised to get at least the start they need on Hilbert space from FDVS.

Sure, a better start is the one chapter on Hilbert space in Rudin's Real and Complex Analysis. The chapter there on the Fourier transform is also good, short, all theorems nicely proved, the main, early results made clear.

Also a good start on the basic results of self-adjoint matrices are the inverse and implicit function theorems given as nice exercises in the third edition of Rudin's Principles .... And spectral theory is in Rudin's Functional Analysis. Also get a bonus of a nice treatment of distributions, that is, replace the Dirac delta function usage in quantum mechanics.

For how to get the eigen value and orthogonal eigen vector results for self-adjoint matrices from the inverse and implicit (these two go together like ice cream and cake) function theorems is in Fleming, Functions of Several Variables. Then you will be off and running on factor analysis, principle components, the polar decomposition, the singular value decomposition, and more.

Yes it is.

I work in tele-medicine and we use rekognition to see if users are following the instructions correctly. E.g. you have to be at a certain distance from the screen, close an eye, take your glasses off, etc.

Also, things like virtual try-on for glasses use facial recognition tech. This allows you to map frames on your face so you can buy them online.

These applications don't use facial recognition to identify users, but to be smart digital assistants. They can function anonymously and don't have to store sensitive information.

There are many good applications.
That seems like a lot just due to a frame change.

If I had to guess, more gear ratios, newer bearings, and rim profile probably all contributed to that. And maybe just a little bit of placebo...

They're languages, or notations. Like https://en.wikipedia.org/wiki/Notation_for_differentiation there's different schools of thought on what's easiest to read, while the fundamentals are essentially the same.

Calculus is a tool, but how we write it is just the notation. Similarly, computer programming (or perhaps a subfield like functional programming) is the tool, and a particular language is just the notation for writing it down.

Ask HN: Am I too dumb for life, CS and STEM?
I'm a 19 years old uni drop out, who is from and lives in a small town in Spain, but I am Ukrainian Citizen because of my parents and nationality acquisition issues.
I'm very concerned with my intelligence and with my complete inability to form and maintain relationships with other people.

I've spent most of my life on the IT ever since '11. When I was a teenager, I told everyone in my town I was smart and made good money online, which were lies, so my self-ego is inflated, but I've come to accept ever since that I am simply dumb.

My grades were average during HS (I especially struggled with math) until the last 2 years before Uni, when they tanked. I didn't pass Chem & Bio during the last year, but the teachers chose to pass my anyway in order so that I didn't have to repeat a grade.

I then got the worst SAT score in class. I got a 3.5/10 in math that made me go to a 2nd tier Uni to study CS. I studied "irregularly" for the SAT. In Uni, I failed all of the mid-term finals I had, even one that was non-CS related. I didn't study "well" for them either.

The subject with which I struggled the most in Uni was programming. During the 2nd semester I got a seemingly unfixable segfault C++ error that lead me to loose all motivation in prog, even though the professor told me the code was sound. I've not programmed ever since, and I find opening a prog book scary.

The only thing that's stopping me from killing myself are my parents, who currently sustain me and let me live in their house while I am "struggling".

I think I struggle to study because of how dumb I am, both in regard to math specifically and in general. Am I simply too dumb for CS, STEM or modern work?

I have no will to progress anymore. What is it good for, if I am destined to be a sore looser genetically and because of my choices. It seems like all careers other than CS suck salary wise and will be automated in some way or another, and I can't stop thinking about this and sleep.

It depends on what country you're in. This USA has an obsession with calling anybody with more than 2-3 years experience a 'senior' developer. In Europe senior is more like 7-8 years.

And yes, v3 is a huge space. That is, several orders of magnitude larger than the IPv6 space. Which is itself humongous.

Edit: Oops. Got that very wrong. Onion v3 is orders of magnitude greater than IPv6 /64. But orders of magnitude less than IPv6 overall. It's like this, I think.

onion v2: ~1.84×10^19 [16^16]

IPv6 /64: ~1.84×10^19 (which is why OnionCat works)

onion v3: ~9.35×10^27 [56^16]

all IPv6: ~3.40×10^38
This might be an unpopular opinion, but I would expect that each newly hired developer (be it junior, mid-level, senior) can and will take time to do train and improve him/herself. I don't mind this being on job time, as long it is not all day. Most times this is even required when doing a task, because no one knows everything, even with X+ years of experience. If this mindset is not there and a newly hired developer requires actual training (like someone else in the company teaching them), then I think he/she will never make a good developer in the first place, because each new task with some obstacle they have never dealt with, will require them to get training from someone else.

I am a big fan of mentoring, but this is related to understanding the existing platform and getting productive working on it, not about teaching technology XYZ.

This opinion should actually go both ways and companies need to be willing to hire developers, even they don't have the 100% exact skills they need and then allow them to improve them on the job. If you got rejected by companies because they don't understand this, then be glad that you will not work for them.
West earplugs! I know this sounds counterintuitive but bear with me. This knowledge changed my life.

So, there is a deep misconception about what it is to "hear", even among doctors; perhaps this can help you.

A quick primer on how the ear works, in an eli5 way: in order to have a large dynamic range, all inner ear cells are "tuned" to be responsive at different volumes. (The response curve of any one cell is like an S, which means it is exquisitely tuned to a very narrow volume range. Anything quieter than this and the response is 0, anything higher and it saturates). Your brain then ignores anything that is "saturated". This allows you to hear both a cricket and a person talking next to you, sounds that are about 1000 times louder/quieter.

And your ear has a _lot_ of these cells, which together cover the entire volume range, which for humans is many orders of magnitude.

Unfortunately, when hearing gets "damaged", what happens is that the cells tuned for higher volumes are permanently saturated, _so the brain ignores them_.

The worse the damage, the lower the volumes that are stuck "open".

So then imagine being in a loud restaurant. The cells that fire for the volume of conversation are "saturated" so the brain ignores them, and all sounds are perceived as being equally "loud"--the world sounds muddled.

The solution, paradoxically, is to lower the volume of _everything_ (by wearing earplugs), which puts the conversion volumes back in the area where you have dynamic range remaining.

If you don't believe me, try it out by just covering your ears with your fingers next time you are at a restaurant--the conversation should be clearer.

Sidenote: the problem with hearing tests is that they test "the lowest volume you can perceive"--assuming that if you can hear a quiet thing, you can hear a loud one. But this isn't how hearing loss manifests itself among most people; we can hear quiet, we can hear loud, we just can't tell them apart!
I don't really get the question? The company I work for (and many others) hire a bunch of new grads who require a lot of training to become productive.

In your situation, I think you're making a strategic mistake. Don't say "nope, don't know anything about react". Spend a small amount of time to do a basic hello world, say "oh, I've toyed around with it and I'm interested in property X but I haven't used it professionally" and you will put yourself in a better position.

The other possibility, honestly, is that you're doing a bad job at interviews and your lack of experience in the relevant technologies is a convenient/polite excuse. That sucks, but there you go

It's about as simple to host a website on tor as it is on the clear web. As a benefit you actually own your domain name instead of lease it on the whim of some third party subject to external countries laws and political/social pressures.

Plus it has built in side-effect anti-DOS properties so no need to centralize through companies like cloudflare.

There's huge benefits to hosting on tor even if it's just a regular website. None of my websites hosted on tor are illegal in my country.
I think it's actually more than that, but regardless, it's interesting (and disingenuous) for Apple to market themselves to the public as being so privacy conscious, all while making quite a hefty profit by selling their customers data via GOOGLE search, albeit not directly. It's probably the most bang for the buck and most profitable thing in history. I mean, making $3-9B profit for literally a few minutes of work (a default setting in an existing app) is pretty lucrative. No RnD necessary. They are making a LOT money by selling their users data.
