Ask HN: Looking for Cryptography Courses
Hi HN! I'm looking for a course about cryptography. I'm trying to understand the basics of the Diffie-Hellman protocol but I would like to get at least to RSA and different kind of protocols and attack vectors. IS there anything like this? Most I've found is some articles or small exercises. I know we use this almost every day, but I want to understand it. Thanks!
OP likely meant deported due to lapse of valid citizenship status, not extradited.

The spirit of what was stated is correct. H-1B workers have very low employment mobility and employers know and leverage this as much as they can.
I just saw that picture. It's an actual LCA approval. Never knew you could get an H1B approved for those rates. I thought the minimum was $60k.

I stand corrected, please accept my apologies.
I sometimes use Ruby as a Perl replacement, where I'd use Perl as a Bash replacement. Little scripts that invoke shell commands and the like, such as one I made to build my website. It's a superior Perl replacement.

I wouldn't use it for serious, big software, because it's dynamically typed, and worse, it has a grievously dynamic runtime.
Regardless of how stupid, wrong, and dangerous this is, it or something just as useless will crop up because government can easily justify wasting money when "your safety" is at stake.
I think a spectrograph tells you more about the constituent elements in the sample, instead of the various shapes of various molecules that existed before you heated it.
This would be easily fixed if H-1Bs were not tied to the employer.

This is fatal design flaw in the program, and if fixed, any worker who is underpaid could easily jump to another job that actually paid market rate without having to worry about any visa issues.

In fact, many employment issues in the US are rooted in the poor decision to tie things to an employer. Healthcare being the worst offender, but also shitty high-fee 401k plans, etc.
haha, this is actually quite witty ^ ^
Eyeing oilfields, U.S. aims to reinforce position in Syria: official
It’s actually exactly like that, but in the opposite way from what you’re thinking ...
There are so many people graduating college in cs that are spending more than year without being able to job in the best economy in living memory. The idea that we need h1bs is ludicrous. They are brought in to suppress wages and for companies to able to get away with poor working conditions.

I'm surprised Farscape would've been expensive. I originally didn't watch that series because the production values didn't look much better than Andromeda (which I didn't like). Course Farscape ended up being one of my most favorite shows.
Nope I know, around 2010 my grandma’s sister insisted not moving out until she got paid another half million dollars (yes USD) and no official/police dared to move this old lady. Of course she got another group of old grandma and grandpas whose health condition aren’t so well and it’s Beijing

It’s called “nail resident” in China. Such story is quite common and unless you are alone force removal isn’t implemented that often. Honestly just call grandpa and let him rest in bed, nobody dares move him
> The only thing you could do outside of that would be to read or socialize.

Hike, play sports, build stuff with your hands, make art, write, go swimming, and a bunch of other things.

I don't recall being particularly bored growing up before the internet became a big deal. It's just that now I'm used to having online access to so many things, it's easier to be bored without access to that.
This was a neat article, the part about AirBnB's attempt at creating a trust economy was my favorite part.

On the one hand, the online reputation does work to a degree; we value lots of reviews and a high average score. On the other hand it fails to prevent many of the usual problems with dealing with people. He calls out the opportunists who have no impulse control, but there's plenty of other archetypes of people who will take advantage of a situation when they get a chance and think they might get away with it. Maybe it's the cynic in me, but this article resonates with my general trepidation when trusting anyone or anything too quickly, especially online. No amount of features so far has solved this.
You sound like a smart guy, but most of your considerations are not as important as you think they are.

1) The San Antonio data center: yes, it's a big and shiny one, but you don't pick MSFT vs AWS because of a shiny data center. AWS has amazing DCs across the US, and if you talk to people in the industry, AWS and Google have the most advanced DC technology out there, with Microsoft lagging a bit (but not too far off).

2) San Antonio has 4 military bases: not much to do with picking MSFT, again. The only argument for "human proximity" is Langley Virginia, and it is still a weak one. You don't need physical proximity, actually you try to avoid it (in case of an attack, you don't want to wipe out both the DC and the smart security people using it for the government).

3) Texas has a separate electrical grid: true, but most modern data centers NEED to have built-in redundancy in relation to: power grid, flood plains, supply routes, etc. Which means this is not really a big advantage anymore.
If You Pick Us, Do We Not Bleed? (2011)
There's an app for that: Truecaller. It crowdsources who is calling.
It's still a bit weird to have a separate interconnection. Even if Texas was an independent nation, it wouldn't necessarily harm anything to be synchronized with another interconnection. The western and eastern interconnections already straddle international borders.
Are you absolutely sure those arguments are pointless
I went to high school with Logan and with Mario. Mario was in my AP Comp Sci class with Mrs. White. I remember being proud of my forays into encryption, concurrency, and network programming.

And then I looked over and Mario had implemented a graphing calculator (as in, take "y = x^2 + 4x -10" and emit a graph) in the windows command prompt. Then, when that was boring, he started researching and implementing the graphics algorithms for drawing lines at various slopes with minimal distortion. And then, when that was boring, he made his graphing calculator support polar coordinates (something I understood only as "oops, my graphing calculator is misconfigured").

Also, he was ~12 years old (IIRC) having skipped a few grades.

I've met a lot of smart people between Carnegie Mellon, Facebook Infrastructure, and the Linux Kernel community, but Mario's one of two or maybe three at the absolute top in terms of intellectual horsepower.

I find that advice hard to accept. I'm older so I spent plenty of time as an adult without the internet (unless you count BBSes). I use the internet to find things to do. Meetups to go to, events on facebook, events and parties friends invite me to, restaurants to go do, etc... I don't know how I would do it without the internet at this point. Maybe it used to be I'd look in the local paper like SF Weekly or LA Weekly but I live in a place that doesn't have those anymore and AFAIK even those are a pale version of what they were in the 80s and 90s

Pun-GAN: Generative Adversarial Network for Pun Generation
That would be quite literally horrible for everyone involved.

The price would skyrocket and the market would be completely out of balance... this would then have at least two horrible effects:

1. The top 500 corporations become gatekeepers to citizenship, as they outbid _everyone_ else for the H1-Bs, they then use their stash of H1-Bs to drive the price of wages down for US citizens...

E.g. "A doctor wants YOUR job, brah. Are you a doctor? NO. I only pay doctors the TOP SALARY. Take your $[shit wage] or leave it"

2. It would force highly-skilled people who have immigrated here, learned from our best systems, integrated into our communities and live, to be completely, mind-boggling enslaved by their corporate overlords... OR give up the lives and loves they've built, take all the knowledge they've gotten, and GTFO.

E.g. "Well if you don't show up 7 days a week for a menial job, FRIEND, it'll effect your review and you could lose citizenship if you lose your job. NO ONE ELSE WILL HIRE YOU."

I could not imagine a worse system if I tried.
Because the US government does repulsive things and many of you are enabling them.
You can call them weird but they may be right.
Ah so this is why I can’t find work as a SWE
can you have to be more specific with what scenarios you are facing where you need this? If ssh and rdp are unavailable what is available?
Negative. Backlighting is vendor specific. Different implementations offer different configurations.

I do agree you probably want a base object for inheritance, exposing a common interface wouldn't be a good idea.

No matter what, you need to implement your abstraction. You're always going to end up with a list of vendor specific implementations.
More density near transit is not a foregone result. It has to be through political will. This is the YIMBY movement.

The peninsula would absolutely be more attractive for Stripe employees. But as I said, the peninsula is building a tiny fraction of the housing as opposed to jobs. The richest executives can move to the few vacancies that open up, but unless something changes, the rest of the employees have to live elsewhere. https://yimbyaction.org/join/
Regarding your list, I'm not sure what specifically you mean by "font shaping", but VS Code definitely supports programming ligatures:

It's hard for me to have sympathy for cyclists as I see so many run red lights and plow directly through pedestrians even when the pedestrians have the right of way. Maybe that's a few bad apples but it happens enough that it feels like the norm. Yes, 2 wrongs to make a right. If the light is red and the pedestrian is crossing without looking then I'd also be upset at the pedestrian.
Wrong. This is popular anti-Meteor FUD spread by people who don't know how to use its features properly or have the engineering/computer science background to design a system to be able to manage computational complexity or scalability.

In 2015, my business implemented a Meteor-based real-time vehicle tracking app utilising Blaze, Iron Router, DDP, Pub/Sub

Our Meteor app runs 24hrs/day and handles hundreds of drivers tracking in every few seconds whilst publishing real-time updates and reports to many connected clients. Yes, this means Pub/Sub and DDP.

This is easily being handled by a single Node.js process on a commodity Linux server consuming a fraction of a single core’s available CPU power during peak periods, using only several hundred megabytes of RAM.

How was this achieved?

We chose to use Meteor with MySQL instead of MongoDB. When using the Meteor MySQL package, reactivity is triggered by the MySQL binary log instead of the MongoDB oplog. The MySQL package provides finer-grained control over reactivity by allowing you to provide your own custom trigger functions.

Accordingly, we put a lot of thought into our MySQL schema design and coded our custom trigger functions to be selective as possible to prevent SQL queries from being needlessly executed and wasting CPU, IO and network bandwidth by publishing redundant updates to the client.

In terms of scalability in general, are we limited to a single Node.js process? Absolutely not - we use Nginx to terminate the connection from the client and spread the load across multiple Node.js processes. Similarly, MySQL master-slave replication allows us to spread the load across a cluster of servers.

For those using MongoDB, a Meteor package named RedisOplog provides improved scalability with the assistance of Redis's pub/sub functionality.
Just remember, you get what you pay for.
How long will a PowerWall power a house? Is it hours or days?
I still don't completely understand why they didn't make Win2k into a "consumer" product. A lot of techies here who installed Windows themselves in that era probably skipped ME and went to that. But all the consumer PCs shipped with 98 or ME.

I remembering hearing at the time that this was about hardware support and/or app compatibility. But my cynical side just thinks they wanted to justify charging more for a workstation SKU for another release cycle.

I like how the abstraction point is at LCD. It's abstracting a specific hardware type, not a hardware feature.
That'll be a $300 cleaning fee for 2 nights, oh and here's a snippy message about how you left hair in the drain and used an extra towel. Be a dear and don't use the toilet next time too, that's extra.
I came across more bird scare devices [0] lately and most are at ~19-23kHz at -20~30dB (personal measures, device ranges differ). I can hear them and it hurts. Fortunarely they are mainly only deployed near entrances and do not have a broad field of effect.
Would be interesting to know how many people do not hear this and feel kinda weird/sick while standing at those places for a longer period of time.

Journey time calculations in Google maps, Uber etc. mean no one I know is ever on time.

If you need to be somewhere at 8:30 and the journey “takes 17 minutes”, one psychologically sets 8:13 as the deadline for leaving the house. You pick up your keys at 8:13, actually leave a few minutes later, hit traffic or take a wrong turn or two, and end up crossing the threshold at your destination fifteen minutes late.

It’s no big deal and quite a grumpy old man thing to say, and I also don’t know if tech is the root cause, but squeezing travel into unrealistically small and algorithmically created windows of time has killed most people’s sense of punctuality, including mine if I’m not careful.
Those are my favorite passages too. For short-term stay, a perfect rating with lots of review is almost a guarantee that you'll have a great experience.

The cleaning fee isn't supposed to be higher than 10%. You can ask for a refund through Airbnb.
> b) PDFs and print spool jobs are indistinguishable,

Then what does "drag a PDF to a print spool" mean?
I lived in Texas during both the big northeast blackout and during the (previous) electricity crisis in California. Both times it was a big point of pride among Texans that their grid was independent of the coasts.

Beats by Dre seems to be doing OK.
Effectively yes. He did let me know that if it didn't work out that I would bear the consequences :-). By that time in my career I knew that you're only as good as your previous decision, good or bad.

It became NetApp's best selling product at the time. I don't deserve any credit for that of course, the folks to did the work to get it out the door and sell it get the credit. My job was to do what the Army engineers do, land on the beach and clear the obstacles between the beach and the objective so that the main force can do what they came for.

When I interview managers I ask them why they want to be a manager. It is not uncommon for them to say, "Because I want to be able to make the right decisions." And I ask them, "And if they are the wrong decisions, are you prepared to be told to leave?" It is a good litmus test.
Microsoft gets the contracts because they do lots of lobbying (i.e. corruption), marketing to government, lock-in tactics that keep government agencies stuck on them, and probably some side deals with NSA since that stuff goes way back. It pays to pay off or help the right people. They pay you back. Then, the others are stuck on your stack due to bad decisions, don't want to admit it, and then sing praises of things they're forced to buy.
But what if your competitor is willing to lose lots of money on large amounts of invested capital until you are out of business?

Uber and Lyft have it tough in that regard. At the end of the day they've got product market fit in a profitable industry. I mean the very worst case is they become more efficient cab companies, and cab companies have been making money for a very long time.

Their prices are artificially low due to competition, and they are in sort of a prisoner's dilemma. eventually one of them will go broke and the other will raise prices, or something will change about the market (such as driverless cars coming). But if one of them passes up raising and losing money they lose.
> I don't understand why so many people are, at the same time, so enthused by the idea of starving government (Because they think most of its services are a waste of money), while at the same time, insisting on spending more on the military than the rest of the world combined.

“It is difficult to get a man to understand something, when his salary depends on his not understanding it.”
No, you don't. That notion has been debunked numerous times. It's just folklore and something drunk people say at sporting events against non-Texan teams.
Yes! I hate being tracked watching videos. I have a self identity I want to put forward. I hate being judged differently based on what I watch. For this reason there are plenty of shows I don't watch via streaming. If I really want to watch I'll find another way. If it's youtube I'll do it not logged in (it's possible it's still attributed to me but I doubt it).

It's illegal for a video rental company to share your watch list. I'm not sure that covers Netflix, Hulu, Apple, Youtube, etc.. I suspect they don't share the list though, they just put you in categories and sell marketing to those categories. That still bugs me since I'm being judged.

OSes and stores spying on app usage is the same. I've never checked out any of the more risque games or VR apps because I'll be tracked.
Not sure I understand where reflexivity applies here. It’s a pretty straightforward concept mostly concerned with feedback loop driven price behavior (bubbles).
I'm not sure if there is a "law" around this, but, I assume nearly all contracts go over budget. Private or .gov.

But, government contracts are pretty beholden to a tight, static budget. Once the money is gone, it's gone. You can't necessarily go ask for additional taxes and budget for the year. Many times, you literally cannot go over budget no matter what. The pay-as-you go, variable pricing you get in the cloud, is actually a challenge in government budget.

In the private sector, when you go over budget..funds can be found elsewhere in the company, etc.
I made a decision. I’m gonna upgrade my iPhone when Apple makes usb-c iPhone rather than lightning socket.

It’s really double spreak on their end. I don’t give a shit about the new fancy features. I just want Apple to simplify the gajillion cables and converters I need to carry around.

I would have to see an example of what you mean, but it should be completely possible though might require converting without using vectorization.

Switching lane size doesn't make much sense to me because ideally you would want lanes that are as wide as possible and mostly be agnostic to their size.
In regards to proximity, I felt the prior commenter was saying that aws had not made a physical investment inside a military state.. meaning the pentagon prioritized bidders that aligned with existing pork/spending priorities. I don’t know if that’s true but it’s an intriguing assertion.

If you charge a high cleaning fee it's utter bullshit to expect guests to leave the place spotless. I am paying you to clean it. The hair in the drain thing actually happened. Any human in your house will leave hair, that is part of normal cleaning in an occupied place along with washing sheets and towels. This is why I've switched to hotels and hostels. The hospitality contract is far more explicit, I don't need to deal with asshole hosts on vacation.
In term of data center importance, you miss a big point that Augusta, GA is becoming the NSA and USA center for information warfare. The NSA has been moving more and more staff from Maryland there. In recent years. Hell, Comcast even dumps a significant budget to “upgrade” their infrastructure near and around Ft. Gordon. So, I don’t believe San Antonio is as significant as Augusta.
Wouldn’t you be proud of the fact that your state government hadn’t mismanaged its infrastructure into the dark ages (pun intended)?
Amen!!
Completely opposite of the nations foundations, I had no idea the concept of property being theft was actually entertained as a feasible concept

Is “Beats by Dre” a “tech” company? I would class it as a traditional manufacturing/sales company that sells audio equipment. And his role as a prolific rapper and producer makes that a good synergy.
Yes, I know. I will extend the list with more information soon. Thanks for the feedback!
Everything speculated here is VC money and financial bubble with unrelaible financial values. Zomato, uber, paytm, flipkart throw discounts at the rate of losses. May be few can survive at the end. This hurts a lot for SMB too.
Is that a unintended consequence or an intended consequence? Seems intended to me.
Do you have a link or guide on where to start with this? It sounds like something that would be really useful!

"Microsoft said that its “Intelligent Cloud” segment recorded revenue of $10.8 billion, higher than the average analyst estimate of $10.42 billion. Microsoft said that Azure grew by 59%; the company does not break out Azure revenue nor operating income specifically, as Amazon does with AWS."

I'm sure Azure is a strong business, but, if they wanted to brag about it, why wouldn't they would break out those numbers? Intelligent cloud includes Azure + 0365 + other stuff.

Google does this with GCP as well. They report Google Docs/Gmail/G Suite + GCP +other combined.
