I'm working through his lessons. They're very good.

I don't have a HackRF but I managed to get the "Hello World" flow, i.e., listen to FM broadcast radio going nicely with a cheap RTL-SDR by following lesson 1, but changing the sample rate.

The version of GNU Radio in the Ubuntu apt-get repos for 18.04 is fairly recent but the GQRX project has a PPA which includes GNU Radio which will hopefully be updated more frequently.

With default Ubuntu I had problems with the WX slider not moving. I didn't realize that WX widgets are old and the advice is to use QT. WX is removed in this latest version.

FWIW, I've since switched to Kubuntu on the same hardware and all widgets work well including WX but I have followed advice and now use QT.

The sound sink seems to work better if you bypass PulseAudio. Give the sink a device name, probably hw.

I'm eagerly waiting for one of these that I preordered. https://airspy.com/airspy-hf-discovery/ I don't have it yet so I can't swear by it but every report from those who have one seems to be very good if you want a general purpose receiver. It covers 0.5 kHz (yes 500 Hz) to 31 MHz and 60 to 260 MHz so not as wide as some but ... I'm mostly interested in HF so plenty wide enough for me.
Why was the CEO of Exxon allowed to do this in 1982? And why didn't the government fund science to figure this out first?
When you realize their objective is the commoditization of software and software development to further increase your dependence on their ecosystem (it's not just Windows anymore, it's Azure and the IDE and their other tools), it seems a lot less benevolent. No company worth their salt does anything for free, there's always a reason.
Anecdotally, i am noticing a steady decline in adsense RPMs for the exact same audience over past 2 years, and adsense is now most of the time not filling the ad slot.

Also, it has gotten very hard to rank in google for new sites. SEO blackhat tactics rule, and even local businesses use them. Google went from win win to win-get lost.

Sadly, now that webmasters need it the most, investments in alternatives to search and advertising have dried up. There is almost nothing except G.
Some technologies are not as obvious as the car but other science fields which are not immediate obvious have advanced a lot since the 1950s E.g medicine.
> I think mostly where it goes awry in the wild is people forgetting the paying it off part.

Which also fits the financial debt analogy perfectly.
This practice is a form of "bundling" in the antitrust sense, and while it is not inherently illegal different rules apply to such behaviors if you've been found to have monopoly powers.
> "Can it really? I saw something more like 130 kW when it started charging, because it was pretty low."

You need to be using the new V3 superchargers, which are just starting to roll out, to get the 250 kW rate. V2 superchargers top out at ~130 kW.

The charge speed does taper off as state of charge increases, but reaches 70% in 19 minutes. This is well over 200 miles of range, hence "decent" charge.

The Model 3 is also compatible with Ionity CCS chargers in Europe, and gets about 190 kW on those.
I've always believed that "debt" is not a great term for this. Because it does not really apply to financial debt.

Financial debt is often repaid simply by bringing in more revenue because of the benefits gained from bringing on the initial debt. The only risk involved in the debt is that there will not be enough money to pay it back later. It is a very predictable and obvious issue.

Technical debt is closer to educated gambling. You are taking a risk that the shortcuts you are taking will not pop up and hurt your company before you fix them. You are essentially saying, "We know this is a problem, but we are estimating that it won't hurt us for the foreseeable future".

The better analogy to technical debt is investing. You are getting a certain percentage increase in productivity(a dividend or other capital gain) for the (hopefully low risk) gamble that your investment will not have a problem and wipe it out or simply cause significant losses.

Developers typically do not like this because when the inevitable few cases of these "investments" turn bad, they tend to be the ones that take on the majority of the blame.
I remember setting up a T1 in the mid 90's. Our upstream was InternetMCI. There was no Web UI. There was no documentation of any sort. The guy (MCI tech) just had me read him routes over the phone and he announced them. Fun times!
Of course, but even the minified versions should net some benefits with compression. Most SVGs probably fit in 7-bit ASCII, which on itself should lead to improvements via (Huffman?) compression. Importantly, as was pointed out, I say “also” not “instead.”
Other countries could educate their citizens about what is really going on inside China in "retraining" camps.

I am sure there are a huge amount of hard evidence in the intelligence agencies about this.

It could sway public and companies from buying stuff made in China, not wanting to associate with this real-world dystopia.

A Chinese economic slowdown may result, causing severe internal problems for China.
A lot of "Safety-critical" certified versions of operating systems just don't include things like TCP/IP stacks or userspace applications. That's probably what WindRiver is referring to here. Otherwise they might actually have to do rigorous design verification and testing on their network stack which would cost a great deal.

For example you can get a "medical grade" QNX but the certificate only covers the kernel, so you have to write and verify the entire userspace yourself.
I don’t have a way to convince you that I’m posting in good faith, but for what it’s worth, I guarantee you that I’m not trolling or seeking to cause disruption.

As others have pointed out, the traditional Western concept of the private-public division doesn’t exist in China. It is in fact similar to historical economic conditions in fascist Europe; specifically, the state-controlled labor unions (and ban on private unions), mandatory party cells within private companies, military involvement in commercial enterprises, and synthesis of the one-party state and a market economy.

I understand that some in the HN community are allergic to comparisons between fascist systems and contemporary societies. I understand they may downvote and flag such comments, and that this creates headache for you. I’m sorry for the headache. I don’t think I’m wrong, and I think my comment was a perfectly valid point to raise. If the sensibilities of HN readers and moderators will not tolerate it, then so be it.
This is why I haven't had future shock in nearly a decade!

also, the changes are coming slower than they once did.
> Whereas Google was previously a way for sites to be discovered and for sites to generate revenue, it is increasingly becoming the sole source system where data is scraped and imported into Google, and Google keeps all of the revenue to itself.

I wondered yesterday: if you provide microdata, Google scrapes it, and you later decide to remove your sites from Google - is Google allowed to keep the microdata and continue to publish it?
In my case, NVIDIA released a "bug" in the driver years ago which disabled the ability of Geforce cards to run in virtualized environments.

They have not addressed or fixed this "bug", and instead point consumers to their ridiculously expensive Quadro cards, which are prohibitively expensive not to mention overkill for most consumers.

This "bug" can be fixed in some hypervisors, for example in KVM, by spoofing certain system information.
> Since USB-C has made its way to some iPads, my guess is Apple is in the process of phasing out lightning connectors entirely.

It could also be more that Apple is trying to position the iPad Pro as a "laptop replacement" - and their laptop has type-C ports - so having the same port makes it feel and work more like a laptop.
Zero losses? No.
This is a complicated situation and I don't claim to have all the answers so I'm just offering a perspective here, but it's not at all clear that the world should loudly support Hong Kong. If the world loudly supports Hong Kong, and China sends in the military, will the rest of the world defend Hong Kong? Would that be a good outcome? If the rest of the world stays relatively quiet, it plausibly allows China to let the protesters win without creating the appearance of being cowed by the threat of violence from the rest of the world.

I agree completely that it's a homemade problem and I have no sympathy for the Chinese government, but that doesn't mean it isn't still very complicated from an international perspective. Of course, the right answer is that China just give the protesters what they want, but what's right and what's going to happen don't always overlap and it's not particularly helpful to end the analysis so quickly.
> This is not how to build concensus for your argument.

Sure, I'm not trying to convince the population being affected with that. Here's how I would say it:

"Your kids are going through 12 years of education. This change to the entire system will make it easier for them to learn, and to be smarter adults with better focusing habits. For some people the hours are tougher right now, I'm sorry, but it's not like those hours came out of nowhere. Your students were going to have school at those hours eventually. We've only changed which years."

It's not about how hard the change is. It's that a few years of early school starts are inevitable, so it's a fair trade.

> If you truly love and care about Hong Kong, give it freedom and leave Hong Kong alone.

But this is fundamentally incompatible with the mainland's entire long-term goal for Hong Kong, which is to strip it of all its distinctive characteristics (which are seen as undesirable products of foreign meddling) and turn it into just another Chinese province.

This is why the treaty with the UK that handed over Hong Kong specified that the "one country, two systems" policy would definitively end in 2047. The idea of Hong Kong as a distinct entity with its own political and economic traditions was something the CCP could only swallow if they knew it came with an expiration date.
Do queries to voice assistants count as zero click searches?
We were presented with an interesting challenge from a potential lead for our edtech platform where they want to be able to run an online course platform in countries where internet connection is a luxury. So it has account for bad/low/unstable internet connection but still provide a way to learn online. For example, when we build applications like those, we don't think about the internet connection necessary since we assume it has to exist. But offline sync etc for this learning platform will be key. This is not an entire startup by itself but part of our current business and a fascinating challenge to solve.
>But then of course the aircraft got saddled with requirements from three different branches of the military at once which made it extremely difficult to design and build and thus very very expensive.

Sounds rather like the Space Transportation System. During design, it went from a compact inexpensive passenger shuttle with modest payload capability, to a complete pig of a ship. And all because the Air Force contributed cash on the condition that it be capable of classified high-payload-pass missions to polar orbits.

It is nothing short of a tragedy that fully-reusable compact shuttles with flyback boosters (like the Rockwell P333) lost out to the disposable-booster design that was eventually built.
JS-mandatory text-only blog posts are bad tech debt.

> Yet companies are adopting it like gangbusters.

Are they though? I don't see any evidence for that. If you are just going by what seems to be popular on HN or tech blogs, that's not really how things pan out in the real world. Most companies are running on "boring" tech.
Leveraging a Developer Blog to Gain Awareness to Your Personal Brand
I lived in this city for many years. I was born here. The problem is, there are now so many other people who live here that what was once great shortcuts aren't any longer. It's been a shift to "light traffic = unusual" from "avoid rush hour and you'll be OK".

I am getting used to checking Google Maps before going anywhere near a freeway. Just a few days ago, I noticed that traffic heading south seemed bad as I was going north to drop off my daughters. I checked Google Maps and it said that going south on the freeway was fastest. I dithered and then got on the freeway. The choke point that was there 25 minutes ago was gone and I saved a bunch of time staying off surfaced roads.

The state highway department has cameras and road reports and announcements of construction. 20 years ago, I would have been on their website. Now I don't have to. I just use Google Maps.

I'm an iPhone user and I do try to use Apple Maps more often because of privacy concerns.
One thing this article gets right is that this seems to be a move back towards the good old "Where do we want you to go today?" Microsoft of yore.
> Basically no academics care what the literal name or publisher of the journal are.

This is patently false. Some universities and even governments enforce whitelists of reference publications, and each researcher is evaluated based on how many papers he manages to publish on them. Failing to meet quotas has a negative impact on the researcher's evaluation and ultimately may result in termination. Researchers may not care if a paper they read was from GloriousJournal or ModestPublication or even arxiv, but researchers without tenure who need to publish to avoid perishing do care. If you're starting out and you manage to produce 1 or 2 papers a year, you'll obviously care a lot where your work will be published
Yeah, that's not like China has a history of successful guerilla warfare or if they were studying the precursor of these tactics at school...

nah other cities are as patriotic as it ever can be at this point.
The issue you are missing is that the sites Google stole that information from often invested money in gathering it.

The CelebrityNetWorth example: https://theoutline.com/post/1399/how-google-ate-celebritynet...

If Google kills CelebrityNetWorth's revenue, Google no longer can scrape updated data from CelebrityNetWorth, because they killed it already. So Google data gets worse or remains static, which quickly becomes inaccurate.

The EU is attempting to fix this issue with the so-called "link tax" everyone has claimed is horrible for the Internet, but really, it's a way to correct the industry. For Google to have good information to scrape, the content creators need to be fairly compensated for that, or else the whole thing falls apart.

Because right now, what Google has done, is acted as a parasite, but a poor one, that actually kills its host.

It really isn't simple. Humans are host to multiple microbial biomes. Why is not understood, but younger people are more biologically active. Hormones are certainly involved, but with smells the bacteria and yeasts living on the skin and in the lungs contribute the most to odor.
Literally the militia was holed up in a compound that could have been erased through missile strikes. No need for exchanging gun fire.

That's the whole point. The military capabilities are very asymmetric.
It sounds like a lot of those problems could be solved, or at least mitigated, by better communication between these developers.
128GB of ECC RAM itself is going to be ~800-1000$ as far as I can find some to fit in a Ryzen build. So it won't be trivial to reach the price point for a full build although Ryzen is clearly great value anyway.
The August 2019 Security Update Review
Right, take the Intel i486 chips. Intel sold 486SX, and 486DX chips, plus a 487DX. Now, as far as an end user was concerned, the 486DX was a CPU as you'd think of it today with integrated FPU (relatively novel at the time in desktop) the 486SX was missing an FPU (still fine to run workloads that were at the time predominantly integer only) and the 487DX was an upgrade to make your 486SX have an FPU

But that was never what was really going on, all these were the same CPU design, except that when yield rates for the FPU weren't so good Intel disabled it and sold those as the 486SX. When sales of the 486SX outstripped supply of dodgy FPU 486DXs Intel removed the FPU altogether from new ones. Meanwhile the 487DX wasn't "upgrading" anything, it just disabled the 486SX and replaced it with a full CPU.
> You mean like a browser?

I can see this being a nice alternative to a few browser options for checking the latest across multiple sites. Pinned tabs, "Open All" bookmark folder, loose tabs, etc. Not ideal, imo, so having them all in one place and unified under a single UI might be kind of nice.

Can't really speak to the UI though since this is unfortunately macOS only :(
An Intro to Flake8
The CPC would like the world to believe that nobody can tell it what to do (not least of which for domestic political reasons), but it's not really the case. China may be bigger and more powerful now, but the (media) spotlight on it is consummately brighter.

I'm not terribly optimistic about the developed world's response to a hypothetical Tiananmen 2.0, but I also recognize that predicting what will capture the public imagination is an uncertain business. And in the case of actual worldwide widespread outrage (and accompanying economic penalties), you can look to pre-JCPOA Iran to see how that turns out. Even the US would buckle under that sort of pressure.
Removal is irrelevant because Google doesn't rely on a license for its index.

You can level a whole block when your troops are attacked and "win".

If China does that, it goes from "that not-fantastic-country that produces cheap iPhones" to "this-is-where-blood-diamonds-come-from".

The way it will act can have a direct and profund impact on its exports and GDP.
Pick any group of feminists and ask them to rate the offensiveness of the terms "toxic masculinity" and "toxic femininity".

Hypothetical question: Suppose in the past hundred years a new species of gnat evolved to live in asbestos insulation. As asbestos is phased out, this species faces an extinction crises. Should humans intervene to preserve the species?

Daily reminder: extinction and speciation go hand-in-hand. It's not like there's a finite number of species and we're going to run out of them.

"So profound is our ignorance, and so high our presumption, that we marvel when we hear of the extinction of an organic being; and as we do not see the cause, we invoke cataclysms to desolate the world, or invent laws on the duration of the forms of life!" ~Charles Darwin

In addition to wattage, my other concern for a home server was fan noise. If it's anywhere that I am, I really don't want to hear it. So I got these amazing Noctua fans and simply can't hear the server. (Updating language based on replies) A datacenter-like server probably isn't designed for that. So it wouldn't necessarily work out.

I have an 8 core i5. I bought Intel (18 months ago) because I didn't want to deal with any AMD incompatibility especially since I wanted to also run it as a gaming machine using VT-d. If I were doing it again, I'd definitely go with Ryzen.

Slowing progress? Why is this a surprise?

Take HN threads on drones, where it's taken for granted that they should be regulated so as to be "perfectly safe".

New personal transport tech, that I hear of mostly via they're being variously banned.

Shenzhen with few-hour delivery on assorted scooters, vs NYC's long-term debates over just what kinds of scooters to un-outlaw.

A visiting teacher from a high-school that still has lathes, near a middle-school with bandsaws, and their New England colleagues shock.

Fire and building codes that are a century thick accumulation of violations of the guidance that you shouldn't make major life decisions in the immediate aftermath of disaster trauma. Built on assumptions of decades-old now obsolete tech.

A high-water mark of running directly onto the BOS-LGA shuttle, with flight attendants later walking the aisles to collect two twenties from everyone, now sunk to security theater and prohibitive expense.

Greyhound leveraging corruption in politics and law enforcement, and press incompetence, to crush low-cost competitors. Leaving a black market mostly for illegals, the poor screwed, and the labor pool less flexible.

An industrial policy around patents that's been recognized as badly adjusted for tech for my entire multidecade career, and I don't expect to be fixed before retirement. Extensive valleys of death between research and commercialization, and between commercialization and long-term availability.

Progress in human interface devices being straightjacketed for decades into DIY by patents, then building towards ferment around VR/AR, only to be laid waste by acquisitions. If the soviet-design-bureaus of FAMG quickly achieve mass deployment, then it may have sort of been worth it, but what a cost of missed opportunities.

One could go on, but I'm unsure even this was useful.

The US has been a major driver of world technological change. And it seems the US has come to embraced friction over ferment, a geriatric peaceful quiet over the dirty disruptive inconvenience of progress.

Watching US writing about China, I'm repeatedly reminded of an old Europe writing about a new US. Sclerotic societies marveling and contemptuous and angry at one less mired. They did eventually improve - rebuilding after massive death and cities become rubble. Hmm, the Black Death had a similar effect. Perhaps with improved social tech and AR, we can manage a less painful rejuvenation?
