At a glance, the product I provide as a contractor / consultant is 'professional services automation'for MSPs and other industries (e.g Kaseya-Connectwise-ITGlue-Brightguage stack)

My answer is that the value I provide is far more strategic and macro level than just systems implementation.

I don't implement systems, I design processes, procedures and work instructions and map the entire org - Creating a living, breathing business manual. I automate and streamline the processes, provide reporting for transparency, continuous improvement and risk mitigation. I provide 'train the trainer' knowledge transfer (integrated with the system itself).

You purchase extensive strategic knowledge regarding the industry and company, which manifests as a future-proofed system that encourages as well as facilitates growth.

For every 10k you spend on my services, ROI will be > an order of magnitude.

My work brings firms up to ISO9001 standards, provides a quality management system, and implements as, customer satisfaction, team engagement, client retention and a host of procedures that SMEs haven't been able to think about or implement effectively.

Point being that (unlike many in this thread) I want to be asked this question from a prospective client, to show exactly what I can bring to the table.
It allows me to show the true opportunity cost of not hiring me (I.e., stagnation and hundreds of thousands of dollars in following years).
There is only so much spectrum to go around. Even with tight beams, providing high speed to everyone in a densely populated area is much easier to do with fiber than with any radio-based system.

In many regions this will be serious competition to comcast, but in cities traditional ISPs won't go away in the next 30 years.
Lower latency and much higher data rates.
Most likely you'll need to buy spectrum wherever you plan to do this.
I think it's important to understand the way that younger teenagers view this sort of thing.

For older people, it's impressive that a teenager goes out there and makes a name for themselves on youtube and then older people will go on and talk about the merits of the media/product being made as you've done.

It's my understanding that for many teenagers the idea of this sort of fame isn't really that big of a deal, it's essentially commoditized, where anyone who's serious about it can achieve a certain level of success. This leads to younger kids to understand that they too can succeed by driving their ideas forward, and I imagine we will see all sorts of entrepreneurship come from Gen Z when they have the skill sets and experience to both raise money from VCs and develop truly innovative new products.
Analog controls have a lot of physical feedback that a screen cannot mimic. Switches vs knobs. Some knobs are multi-detent switches. I can look at a radio, see the frequency, and know how many detents to get at or close to the desired new frequency while looking elsewhere because I can feel the increments happen, same for transponder codes, same for changing mode or view.

And in turbulence and/or at night, or heavy workloads, it's even more handy.

About the only replacement I can imagine being better is the Firefox (film/novel) interface. I'd even learn Russian just to have that interface. You must think in Russian.
Satellite can be amazing tech. But it's still not going to be the best viable option for high bandwidth connections in medium to large sized cities. As companies like centurylink build GPON and 10GPON based FTTH networks (example: Capitol, Hill, Seattle) it's quite possible to do 900 x 900 Mbps symmetric, though slightly oversubscribed, residential connections.

DOCSIS3.1 over old copper coax cable, with enough RF channel bonding, can also do 300 to 900 Mbps downstream, again slightly oversubscribed. With much less upstream because the RF channels are usually allocated asymmetrically at a ratio of 10:1 or thereabouts.

This is by no means going to hurt Comcast. Comcast (and similar companies like Wave, RCN, Charter, Shaw, etc) are building DOCSIS3.1 and also overbuilding their own networks with fiber. They have the established right of way through major cities, both on pole and underground, and can incrementally build a FTTN/FTTdP architecture with existing copper, and will eventually overbuild everything with singlemode fiber to the customer.

What this will be revolutionary for is small towns, remote/rural areas. In the US as an example the market for ISP last mile connections that is presently served by either WISPs, or in places where no WISP exists, two-way Ku/Ka-band VSAT terminals (HughesNet, ViaSat, etc). The capacity constrains on traditional geostationary consumer grade VSAT services result in terrible things (TDMA oversubscription that pushes latency to 1150ms during peak hours), and things like 20GB/month transfer quotas. That's for a typical $100/month, 24 or 36-month term with the latest generation of Viasat's services.

For polar regions this will be a big deal because they are presently almost entirely dependent on geostationary C and Ku-band satellite capacity.

On ships: Very relevant and has the potential to capture a ton of market from Inmarsat's I-4 and I-5 series satellites and tech, and Iridium's upcoming maritime products. With a sufficient number (thousands!) of polar orbit satellites it can cover mid ocean areas very effectively.
What will the latency be like? My understanding is that these satellites will be in lower orbit, allowing for shorter round-trips... But how much shorter exactly? And how would that translate to real-world latency? Presumably there would be multiple hops involved in traversing the SpaceX network?
Right, but low latency and high bandwidth since the satellites are in low earth orbit. So, a threat to legacy ISP providers. And a boon for rural dwellers.
For many things, this is exactly what I want. Walmart has great prices for the same as their competitors and their service is ok.

They aren’t Costco, but they deliver exactly what they promise - minimal quality for the best price.

But I’d never buy non-consumables from them.
I wonder if you'll be able to get a device small enough for this to replace satellite telephony. I enjoy backpacking and would like to get a sat-phone for emergencies, but it's kind of cost prohibitive.
I think it's smart for Walmart to diversify it's business into something other than retail. They need to grow revenue for shareholders, I don't think there's any more large-growth opportunities for Walmart in that sector.

I do think this move is rather unoriginal, and is a 'me too' effort vs CVS & Aetna.

Walmart is the #3 largest Pharmacy in the US, so there are potential savings and efficiencies to be had with a health insurance merger.
This is the most fucked up thing I ever read.

Gogo works over water on their new(ish) 2ku band installations. Two years ago I flew to Hawaii on one of the first Delta flights outfitted and got some pretty good speeds (and oddly enough it was free because of "limited connectivity").

Also pro-tip, if you have T-mobile you can use Gogo for free. There's a small upgrade fee to make it work the entire duration of the flight. It's intended to be mobile only but I'm sure some people here can figure a way around that ;)
Ahh, yes. That makes sense. No batteries included.
The same thing they do today with VPNs: outlaw it, put reasonable restrictions in place, accept that some amount will slip through (or heavily police it and hand out lots of jail time, depending on local situation, political climate etc.)
I opened the comments half expecting comments more inscrutable than the discussion itself. Didn't expect the extant sentiment.

So, maybe, this question isn't so stupid:

...what's the point of this type of discussion? What real-world, non-theoretically-based situations, would I use this type of understanding in?

I've tried to figure it out and I'm not coming up with anything relevant. I know there is relevancy to be had here, I can see that, I'm just not figuring it out myself.
const Name = (props) => <div>{props.name}</div>

const Age = (props) => <div>{props.age}</div>

const App = () => <div><Name name={'Zed'}/><Age age={20} /></div>

Is about as simple as it gets. This sort of composability can go _very_ far without needing any of the other API methods.
SpaceX will obey local laws and geo-fence the service.
Not a pilot but like you I can't stand them cars. Tactile means I can keep my eyes on the road, which is the only thing that matters while driving. I found myself glancing at the screen before touching it and got rid of the touchscreen only device that was in my car and replaced it with something that has the major functions under a button. And I don't use it for navigation, I have a dedicated device for that I've placed on the right of the rear view mirror.

Airplanes have to deal with turbulence and I really would not want to change any critical settings on a touch screen while being bounced around, I remember when I still had the bloody touchscreen device in the car I mis-touched and I had no idea how to get back to where it was before, it took a stop at a gas station to reset the interface. In general I think the obsession with getting rid of knobs and buttons is a bad thing.

I'd love it if there was a general prohibition on touch screens in cars, I'm pretty sure that it is a safety issue. Any device that requires that you take your eyes of the road in a vehicle is a bad device.
Facebook Scandal: 31% Tech Employees Say They’ll Delete Facebook
Well, yes, but Ku band means all the benefits of the simple antenna are gone.

Do they try to enforce "mobile only" solely with a MAC prefix database?
They also treat newlines (\n) in the XML payload as an invalid character for <airquotes> security reasons </airquotes>. Authorize.net is an antiquated company that is slowly disappearing, having lost the race versus Bluesnap and Braintree, just to name a couple of providers in the field.

Good riddance.
So, they'll lose their 5% margin on you.

If your odds of noticing the bump, and caring enough to drop them were <80%, they still made money.

States passing laws to govern “smart contracts” have no idea what they’re doing
I was just looking at Iridium and they seem to have very low latency of around 40ms roundtrip [0] but very small throughput. If SpaceX (or whoever else) can address the latter, then 40ms will challenge any ISP. If you combine this with the adoption of new protocols like HTTP/2, the user experience will be definitely comparable.

Comcast is no more just a dumb pipe. Thanks to their acquisitions they would, in case of this scenario, simple reinvent themselves as a content producer (which they already are).
Thanks for the feedback. The videos I have on my YouTube channel to-date are all from my Twitch streams. For or better or worse, these streams capture my working habits: when the camera isn't running, I'm doing the exact same thing -- even talking to myself. :) For some reason, suffering from ADHD, music helps to focus my attention. I've never been able to explain why.

However, with all that said, I am producing non-stream content that will start airing on my YouTube channel soon (within the next 30 days). This content will be more structured and focus on a specific topics with a set lesson plans. These videos won't feature any background music. I hope you'll be able to enjoy these when they're available.
Crap, you're right. Wait, I mean, of course I meant volume when I said "size".

But I think you can seriously make the argument that not only is "largest number" an empirical question, but the answer depends on your units. I'm not sure that's more absurd than the stuff in TFA.

The problem with that is that it places a fiscal incentive on the companies to make the government as ineffective as possible, in hopes of exploiting regulations and quashing competitors.

The solution to corporations breaking the government isn't to just say "well, it was ineffective anyways".
Charting Deaths: Reality vs. Reported
This lifecycle exists for a fairly rare use case. Why do you use it often? Instead of keeping state “in sync” with the props, can you just read it from the props?

For the rare cases where you do want to retain previous props, yes, we’re asking you to be explicit about it. This will allow better memory usage in future versions of React, and also avoids the need for an extra `prevProps !== null` check that would need to happen in every `getDerivedStateFromProps` method.
99.9% of the time FCC conditional approvals for new tech will eventually convert into final approval. It's just a procedural thing.
Maybe we read different articles (or different comments) but my sense is that commenters here as a whole were earlier and are more consistent in their criticism and dismissal of "crypto" scams. I'd already been reading warnings here for a year or two by the time I started seeing this stuff mindlessly hocked in mainstream sources.

(Your broader point may be right, I just don't think the current crop of scams is a great example.)
This is really good because of the attention paid to the ease and ergonomic physics of dragging the nodes. Keep up the good work.
Recalling when I was at college I used machine code to pre-fetch data into cache to improve an algorithm by 40x, even the professor did not believe that and asked me to explain all the hacking code I did and later on gave me the highest grade for that class. Yes ASM and machine-code are fantastic...

Yeah. Teleconverters are true lens "stress" testers.
>Do they try to enforce "mobile only" solely with a MAC prefix database?

Nope, way simpler than that. Just a simple user agent check. Although recently they've made some changes that make it harder, but just loading up the iphone simulator gets around it.

Now watch someone from Gogo see this and fix the loophole.
I would guess that the burden of proof is also less for deportation than for criminal conviction.

I've had 130Mbps on my 4g line. I work frequently on mobile hotspot, it already works nice if you are on a non-congested tower.
Geosynchronous orbit is 35k kilometers up, which a calculator tells me is 119 light milliseconds from the surface.

Iridium satellites were the first set of satellites I could find numbers for that made any kind of relevant example. They orbited at 781 kilometers, or 2.6 light milliseconds away. Over 45 times closer.
Sometimes i wonder the evolution of cockcroaches' grossness has something to do with its high survivability?
That's quite a minor recall compared to almost any typical recalls in recent history is it not?

Although that's not to say it isn't still a serious issue for a smaller firm like Tesla.

Unless the rooftop CPE can be significantly disguised, it'll be difficult for places like Iran. The Iranian government periodically goes on (not very successful) campaigns to get people to remove rooftop Ku-band TVRO, Rx only satellite dishes. Those don't transmit. With a portable spectrum analyzer it will not be difficult to identify starlink rooftop CPE radios.

This is ultimately the same problem that applies to rubber hose cryptanalysis. From a network engineering perspective, if an authoritarian state can use sufficient local resources to control the OSI layer 1, it doesn't matter how good your L2 to L7 are.
Show HN: SF Data Weekly, for people interested in building data platforms
Agreed. I read the first edition and it was a pleasure.

The second one felt like "what's the point? I'd rather learn C".
We maintain more than 50,000 components at Facebook, and I don’t believe your assessment that “APIs undergoes drastic changes every few months” is accurate. The component API has barely changed since the initial release five years ago.

When we need to make changes, it’s the team of 8 people that need to port all those dozens of thousands of components to new APIs. It would be infeasible for us to break APIs every few months, or to do so in a manual way. This is why we embrace automatic codemod scripts.

There have been some breaking changes between major releases (which have a roughly yearly—not monthly—cadence) but we always provided automatic scripts that convert your code as much of your code as possible automatically: https://github.com/reactjs/react-codemod.

We also call attention to the automated migration scripts in all major release blog posts (for example: https://reactjs.org/blog/2017/09/26/react-v16.0.html#upgradi...).

That’s the only way we could maintain dozens of thousands of components while still moving the library forward.

I hope this information is helpful. You can read more about our commitment to stability without stagnation here: https://reactjs.org/docs/design-principles.html#stability
Yep. Say you have ten days of vacation per year (welcome to the USA!) This means you can “get serious” with max 10 companies per year. I’ve in the past interviewed with that many companies in only a month! You need to be very creative with your time to do serious interviewing while still working.
Facebook is more powerful in Washington than you realize.

Components are just functions -- HOC's are higher order functions. The pattern dropped out like all patterns drop out -- from use. Its nothing specific to React, but to functional programming
Unlike the quality issues with the Model 3 that continue, this is no big deal. It happens to other manufacturers all the time.

Seems like a quick fix.
Most automakers sell millions and millions of units in a short period of time, but Tesla does not. I’d be more interested to see what percentage of Tesla’s have been subject to recalls vs the total shipped, and compare that to a similar mainstream metric.

> All they said here is that the passwords are hashed and with a reasonably secure method -- bcrypt (although without knowing work-factor and percentage of passwords, it is hard to know just how strongly)

Speaking of proper password hashing--are there any methods similar to bcrypt but where you can increase the work factor on the currently stored passwords without having to have access to the plain password?

E.g., suppose you have a database of hashed passwords with work factor 4. You want to up the work factor to 6. The usual way to do this that I've seen is to start using 6 for new passwords, and when people with existing passwords log in you verify the password with the 4 hash, and then before discarding the plain password you 6 hash it and update the database with that.

But that leaves 4 hash password still working for however long it takes people to get around to logging in. If you are raising the work factor it is presumably because you think the old work factor is no longer secure enough, so you probably don't want the old 4 hashes to keep working.

You could remove the 4 hashes of anyone who doesn't login and get updated within a reasonable time, making them go through the "forgot my password" routine, but that will annoy them. Hence, my curiosity about ways to updated the work factor more directly.

There's a kludge way to kind of do it. Go through the database, take all the 4 hashes, and treat those hashes as if they were the passwords, and 6 hash those and store them, along with a flag that marks this as a transitional password. When a user with such a password logs in, you 4 hash their plain password, 6 hash the result, and if it matches, you then 6 hash the plain text password and store the hash, and remove the transitional flag. But this is really quite ugly.

Careful.

Major advances in communication technology also precede major military upsets. Only the victors labelled those as progress.
My outlook is there are definitely more important things than money like time - time for whatever you want - loved ones and friends, relaxation, enjoying life, charity work, etc. Money buys you time and unless you're reckless with it - it can remove or reduce a lot of stress. It makes a marriage and having a family much easier among other things.

I think we worship obscene money (ex: celebs, athletes, tech founders) and get rich stories but probably don't worship money as a whole - if we really did we wouldn't be in such debt buying crap and having no savings. 63% of Americans don't have enough to cover a $500 emergency. [1]

College students could be having that financial outlook you mentioned as a result of the crazy debt they took on. And the fact that 75% said raising a family was a life goal, which is higher than boomers and Gen X, at a time when raising a family is way more expensive than it used to be. If this is the case, then they actually value education and raising a family over money and money is just a means to attain those things. So I don't think that's alarming.

What's alarming to me is poor financial education and decisions and the desire to get rich quickly or feel like you're owed $X salary because you have $Y debt which I see with many new graduates.

Where can I find top notch designers who can create high quality landing pages?
In real world practice Iridium's current satellites (not the next generation) have latency from 700ms to 1400ms to the gateway. It's also 2400 baud for data, something like 2400baud+1200bps of FEC for voice. Actually kind of amazing that they can fit intelligible voice through that bitrate with voice codec technology that was finalized 19 years ago.

The raw RF latency of Iridium in its present state does not correspond with the network topology at layers 2 and 3.
This is 2018; time to stop coming up with half excuses and fix your security bugs instead of protecting yourself by removing a potential character from being used.

I think it's more intended to be utilized as an abstraction in something like Apollo. It'll be interesting to see what sort of cleaner patterns emerge out of using Contexts under the hood.
