Hi HN

PodTalk is a podcast app that lets you add voice comments and talk with other listeners.

It features a Reddit-style comment system with upvotes and all that.

Right now there is only one podcast available: EconTalk. If there's enough demand, I will add a couple more. I'm deliberately limiting the podcast selection.

I made this app because I often talk to myself while listening to EconTalk. I thought there might be other people doing the same.

I choose to take the thesis route, but I still have 27 hours of coursework to complete as well. My goal was to have 2-3 publications over the next year, but I am not sure how feasible it is. I am in the middle of determining a route for my research right now. Leaning towards AI, but also enjoy Operating Systems, Networking, and Security.
What happens for that scientist when they have to dive into Julia’a stack to debug something weird? In Python and C, you have established debuggers, semantics etc, which means that, yes, there are two languages instead of one, but neither is a moving target compared to a language which just had a 1.0 release.

I get the issue with scientists writing poor code, but Numba has largely solved this problem, by packing an LLVM JIT into a decorator which can be applied to any numerical code to get same speed ups as Julia, except no language switch required.

Citing slow code in the wild with a fast rewrite is a hilariously poor anecdote performance wise. I’ve rewritten Fortran code into Python and gotten speed ups. Regardless of the language, garbage in, garbage out.

Stan is an example where the modeling is “just” a DSL implemented as C++ templates. Does that make that a good choice?
That isn’t true. In most states, the local district sets their own budget and legislators might provide some additional funding/oversights. Prop 13 in California gave state legislators more power (since school districts had to rely on less property taxes and more direct state funding) but that is unique to California.
That agency would have jammed communications in the area so no alarm would have been raised, unless raising an alarm was their actual purpose.
The thieves would have been wiser to take something, anything to make the narrative of the original break in more believable. They didn't sell the narrative well enough, which left people curious.
f.lux author here, still slogging through the article. It is hard to understand the light levels used because they use "power" (uW, mW) from a laser, and not "irradiance" (uW/cm^2 or mW/cm^2), so which area they have concentrated that light over is hard to understand. All I can see is it is from a laser, so the irradiance could be extremely high.

The human lens filters most light at the peak of the given spectrum for free retinal (383nm), and so once you get to 450nm like an LED, the hazard data in the visual range is 100x less sensitive, see Fig 1 here:

https://onlinelibrary.wiley.com/doi/pdf/10.1111/j.1751-1097....

It bears repeating that computer screens have <5% the hazard-weighted irradiance of a blue sky. (Can't make a direct comparison with lasers.)

Not sure the conversion to white light is correct, and it is unclear to me right now if this much retinal is available in vivo.
I imagine there has to be a significant enough scaling difference between the capital raised by IPOs, which is a one-time event, and subsequent cash returns to shareholders in various forms, which can be characterized as interest payments on that one-time liquidity event (absent subsequent share issuances to keep this description simple) that never ends, versus a loan-then-repayment or bond issuance-then-repayment, that makes the IPO compellingly attractive. I've also heard that many leadership teams choose an IPO because it is easier and faster to raise the sums involved than going to the private markets, and when in a "move fast and break things" mode, competitors hot on your heels, that's got to weight heavily in favor of an IPO.
Thank you for asking the question I was about to ask.

I am ambivalent over whether it has multiplexing or not. When I need parallelism I fall back to OS threads if available or processes. One or the other is usually always a first class citizen. Whats not that common, are real lightweight coroutines.... I want my laptop to be able to simulate the transport layer over a sizeable portion of the internet, while I watch youtube.
> People who are into more secure communication do not randomly click on anything

Even if that wasn't wrong, it would be a fatal limitation for a social app which relies on network effects. Even if you were actually super-humanly capable of not making mistakes you'd end up using the apps that everyone else you know is actually on.
So I have two responses to your comment (which I thought was great btw).

1. I think your assessment of Confucianist culture correct, however, as a counter argument, I think that Western culture can sometimes under value the importance of duty as a facet of happiness. People, to some degree, need to feel useful to be happy. Whether its being useful enough to get a paycheck or to be able to fulfill the needs/wants of friends/family, it doesn't seem to me that the importance of duty is merely an artifact of E. Asian culture.

2. I actually think there is a third problem to the "immigration-fueled sociopolitical rifts" you describe. In my own personal experience, you can fully understand (and even appreciate) the cultural perspective of another and yet fully reject the impact said values have in your life. Understanding != acceptance. Just being you understand something cognitively does not mean that you are required to accept it as an acceptable element of your life emotionally or socially. In fact, when the situation is zero-sum (like you can only spend a certain amount of time either doing your own cultural thing or the cultural thing of another) choosing the other can signal a rejection of your own culture for that of the other, which may very well have some serious social consequences. I don't think the response of "let's just not choose to believe a particular perspective is correct" is effective enough.
Using explosions to put out fires isn't an entirely novel idea: it's actually used in oil-well firefighting[1]. That said, I have some serious concerns about the applicability of this technique to wildland firefighting.

In the interest of full-disclosure, I am a former firefighter, but I was mainly focused on structural firefighting. We did respond to wildland / brush fires, but only got involved in direct suppression activities on the smaller fires. Larger wildfires we just provided protection for exposed structures and let the Forestry Service handle the primary suppression efforts. Anyway...

One of the main dangers of wildland fires involves something called the "wildland / urban interface"[2]. This is where homes and urban construction border on and/or intermingle with wildland areas. When you hear about "Wildfire X destroyed N homes" this is usually referring to events that happen in the WUI. I don't think it's hard to see how dropping bombs in this area could be problematic - even using the specially tuned bombs referred to in the article.

Also, a wildland fire isn't like an oil-well fire in that you don't have all the fire concentrated in one small, well-defined area, where you can quickly "snuff" it out. In a wildland fire - especially in the driest, most dangerous conditions - it seems likely to me that the same shockwave that snuffs out flames in a certain area, might well spread embers that actually spread the fire to an even larger area.

Maybe there's something to this, but overall I'm somewhat skeptical.

Not a problem in bases divisible by 3.

It's exactly 0.1 in base 3 and 0.4 in base 12, for example.
I find it disconcerting.
> it’s every bit as deluded and cringeworthy as I’d expect.

Not deluded at all. Sorry if you didn't get it. It's very strange that puritanical adherence of America has been rolled back (mostly) but the pedo label is still so toxic in American culture that it's assumed that other cultures share the same values.
(Totally unrelated, sorry, but about a month ago you and I had a brief exchange about the placebo effect.[1] I got distracted and missed your last reply and never responded. Sorry about that. It's too late to reply on the original thread, and I don't want to hijack this one, but while looking for an old comment I saw your reply and felt compelled to mention it to you. It was a good exchange IMO and I didn't mean to "ghost" on it.)

Can you be more specific about "severe eyestrain"? E.g. if there is pain, where? Eyes dry, red? Difficulty focusing? Peripheral vision? Have you had an eye exam when the strain is present? When the strain is present, what happens if you switch to reading paper? Or switch to distance vision, e.g. looking out the window? How long does it take to recover from the strain when reading or looking into the distance?
I don't think your argument holds. Case in point: it is possible to make poison tasty.
Do you think it make sense to judge the entire work/life of someone by an affirmation made at some point in the past on a public forum ? From a moral point of view people are not black and white, there are infinite shades of grey in between.

If you dig deep enough you will find morally questionable things in everybody's past.

That being said, that tweet was a bad idea.

SilenceIM and pidgin-otr add e2e over existing networks. That means I can attempt to send messages to people who won't be able to receive them. That is the opposite of 'just works'.

With Signal, or other services, where e2e support is a mandatory part of the client and is the only way to send messages, if someone is available on the platform, I know that I'll have a e2e message stream. (subject to MITM of key exchange, of course)
1 Trick to Learn Something New – A Day in the Life of a Software Engineer
I'm not an expert either, I just know some and have heard of some of these issues—so I don't have anything definitive to say, just that it's not a clear win in my eyes.

I also don't know if the wheat plants are even sugar-limited, for that matter! I guess what I'm saying is "plants are complicated". :-P
Not without conspiracy or organization.

Those who say yes when asked to engage in profit-generating yet morally ambiguous or immoral behaviors will rise and be rewardedm; those who say no will be marginalized and removed.

This is an essentially inevitable outcome for anything other than a nonprofit or benefit corp. Witness the decay of Google's moral compass, and more recently, the outright contempt for ethics at darlings like Uber.
What if the research options available are not something you're too interested in? I had a professor tell me I could work with him, but he said I had to work on what he has decided. That doesn't seem very attractive to me.
Do you have a spectral output chart for those LEDs? You might be surprised how much blue is still in the output.
Just added and deployed docs above the fold on home screen. Thank you!

- Whoops - we forgot to update that - we added it to cloud a few weeks ago. Updated our docs - thanks!

- Hm - good question! I think there's currently no limit, but yes, that's a good idea as we scale. We want to have a "generous" free tier because most engineers we meet find Retool fairly interesting. And so we want to allow people to play around with, without having to pay us.

- Yes - that's correct for now. Once we have a better on-premise process, we'll open it up! :)

Thank you for the questions and feedback!
I think you aren't using the term API correctly. This discussion is about APIs for third party developers to write apps. The fact that banks own mobile apps often use REST to communicate with their backend does not make such a protocol an API. For one it's not documented, for another it may change without notice.

Of course if you define "API" to mean literally any form of communication between processes or devices then sure. But then you'd have to consider GSM or FTP or TCP/IP itself to be APIs and I never saw them described that way.

My main point is that an interface that's just being driven by human interaction has very predictable load characteristics. If you open up a true API to third party developers they may come up with new uses that aren't directly human driven or may even be batch jobs. You don't have much control over your inbound workloads anymore.
I'm not sure I'd be so paranoid. We've read of people managing to hack the key openers, etc. They're an attractive target.

I mean, if you were going to leave a box containing $30,000 on your doorstep. A box not only containing 30k, but a box that was labelled that it contained 30k. How would you protect it? Put a serial number on it so you can prove it's yours? A bike lock? A motion sensor? Cement it into the ground?

What lengths would you expect someone to go to, to try to walk away with this box? Just give it a little kick to see if it moves? A screwdriver or a pry bar? Angle grinder?

Once you divorce yourself from the commonality of a car, it's quite bizarre to think that not only do most people leave their second most valuable possession (or most valuable, if you rent your home) on their doorstep .. but that they just assume it won't happen to them. It doesn't take a targeted attack for someone to realise that that exposed, valuable, mobile asset is .. well, exposed, valuable and mobile.
I can't imagine joining a startup in today's day and age named after the founder (Rigetti computing/ Chad Rigetti). Props to the work they have done so far, but I personally would not have enough faith in the CEO's motives to join a company with a name like that.
Here here, re: content.

My usage of Facebook would probably increase if there was a way to filter-on site-keywords in and out of my newsfeed instead of relying on a browser extension.

As it is, I'm constantly hiding posts, snoozing or unfollowing people altogether-thinking "Fine Facebook, if you want to use algorithms based on how I use the site to customize my newsfeed, customize this".

Seems the site hasn't yet picked up that I don't want everyone's oversimplified political hot takes (but I like one Nicholas Cage meme and suddenly FB reacts "Would you like ALL the Cage recommendations??" No, not really). I like checking in on my friends, and that's the extant of how useful FB is to me, but there's a real fatigue to the political fatalism front and center.

So, twitter it is. So I can get my oversimplified sports hot takes. Those are at least humorous and entertaining.

If a social network comes along and grants me that kind of control, I would gladly beta that.
It's an interesting choice, and while I saw it coming after they added a page to view your friends' gaming habits, it's not the long-term move I thought they would take.

Discord basically started out as "Slack for gamers", and very quickly (IMO) surpassed both Slack and Skype in terms of functionality. I don't have to have a different account for every server I'm in unlike Slack, and their video and audio calling has always been much more stable than anything I've gotten on Skype.

With that in mind, I would've thought that their next plan would be to improve on what they do best, and try to market to the professional markets and take Skype and Slack head on. Instead they seem to be veering off and doubling down on the gamers. Judging by the number of people I see who have it, I imagine the profit from Nitro may be enough to keep the company going, and the Slack crowd won't be as lucrative as the opportunities from taking some of Steam's marketshare.
Cool idea! We built a lot of internal tools at my last startup (bloc.io) because it was an operationally intensive business. I would have definitely tried this out.

Your premise that most internal tools use the same building blocks seems accurate based on my experience, a lot of it is collecting and analyzing data.

I'd also add that the most underrated cost is maintaining a tool, developers are usually excited to build something new and when they're working in a fresh codebase they can build and iterate quickly. The real pain is when no one has used a tool in a couple months but needs it now, and the original dev has moved on to some other project so there's no one available to update or fix it. That's one of the biggest reasons we started using more third-party SaaS options instead of building our own, even if they were expensive and only an approximation of what we actually wanted.
I had a blast playing this. I cant be critical at all.
I can't wait to see what the ancient systems that need support in 30 years will be.
That makes me think it's even more likely not his full time job.
That would make me crazy. Before an important meeting that would seriously throw me off. It's a good play
First of all, if you screw up and say something is in stock when it's out and that thing is critical to someone's life, someone could die. Even with mismanagement of an inventory system.

So let's not descend into "but lives are at stake" hyperbole.

The vast majority of the database are fines and tickets. And it's likely a lot of this stuff is duplicated elsewhere. If the police have a warrant for someone's arrest, that warrant is also on file at the courthouse where it was issued. If they booked a suspect and he went to county jail, the county jail has that information. If the entire evidence log is wiped out, all of the necessary information is written on the bags.

There is a ton of redundancy both intentional and accidental built into law enforcement. No one is dying because you need to restore the database from a back up because Larry deleted the database again.

And even still. Even if the consequences are that much dire, the work is the same. There is nothing special about the data that makes it any more or less difficult to store.
> Statistics is just so much more useful outside of the niche domains where DL is extremely effective.

This. Sorry had to.
"The researcher found that a molecule called alpha tocoferol, a Vitamin E derivative and a natural antioxidant in the eye and body, stops the cells from dying. However, as a person ages or the immune system is suppressed, people lose the ability to fight against the attack by retinal and blue light."

Does this mean that consuming alpha tocoferol can combat the toxic effect of blue light? If so, at what dosage?
I don't think that's "the problem". There's plenty of demand for the cars. Elon Musk fatigue may be a real thing, but that's more related to the news cycle (and the Twitter cycle), in my opinion, than Musk himself.
Baltimore is in striking distance of the DC area, where salaries aren’t known for being paltry due to federal largess.
On the contrary in fact, I find gazing at the blue sky to be calming and enjoyable, and find it promotes diffuse thinking, which can greatly speed up problem solving.
Nah, BMW-thieves are incredibly resourceful. They managed to steal parts of the dashboard and airbag from my neighbours car, without further damage, while in the driveway with the alarms not triggered on a modern 3-series. All the neighbour noticed was the dog barking a few times at night. We all sleep within 30 ft of that car. Practice makes perfect. Those parts are sourced to eastern Europe and are stolen on demand.
8 years is a long time though, and could potentially be more than one company.
What's your twitter username. I want to add you as a maker to the producthunt project :)
I have a friend who gets regular migraines. He takes triptans to abort them, but if the frequency becomes too much he takes a low dose of psilocin and it banishes them for a couple months.
So LED bulbs would be even worse, right? Is it time to go back to incandescent bulb?
Numba has user defined types,

https://numba.pydata.org/numba-doc/dev/user/jitclass.html

No one intends to fix Python but it’s straightforward to do things like Numba: use a decorator to read out the AST for a function, reimplement it however you like and pass back the compiled function, and document the semantics.
Probably because it's not quite an opinion piece. A buyout at this massive scale would've been rumored by now by the potential suiters. The only other alternative is single-buyers who are willing to put up that much personal capital, also highly unlikely.
Quantum Computing: Will It Kill Blockchain?
Haha, this sentence:

Widely considered, I love it.

Where is the "e-mail message going around the globe" gif and the "made in FrontPage '95" banner?
The Scapegoat
They aren't calling their fellow white males "crackers". By using such slang intended as an insult, there is an implication that the "other" is "lesser"
How’s this Elon’s fault? He’s endlessly criticized in unjustified ways. That guy didn’t reasonably critize Elon’s plans, he instantly attacked his motives and said to stick his submarine up his rearend.

And 10% of Thailand’s GDP is based on the sex industry or $6.4 billion a year. “Pedo” is kind of a misused connotation but when people get attacked their impulse is to respond with a personal attack.

It’s not a “meltdown”. It’s just human nature magnified by Twitter.
> so that high earners who have accounted for most of the wage growth recently contribute a fairer share

I don't disagree with removing the wage ceiling, but if you word it like that you're pretty much guaranteed to fail, because the equal and opposite to that is "Cut the payroll tax so I don't have to fund the bozos that decided to party all through school instead of working their tail off like I did."
>Doesn't that indicate that my pupils were initially dilated in the darkness and then constricted when I began looking at my bright phone?

Somewhat constricted. They're still more open that if they were in a fully lit environment, even more so in the sun.
Sounds interesting, tnx for the info! I'm interested in new promising ICOs. I just read about iTrue platform at https://itrue.io/ which will enable businesses to improve authentication through biometrics and eventually build and market their own applications on the iTrue platform and ecosystem. I think it will be win-win project too.
> All my friends with PhDs are unhappy, and do not enjoy doing research. They are all intelligent, some a little bit creative, and only curious when forced. They are experts of citations (a tease that never gets old to me, sorry) and I’m afraid are most concerned with not being left behind or achieving prestige.

> Having had countless long late-night chats with them in empty bars about this, I gather their habits of conformity got them that far and let them down once they were on their own. They consistently think what I’m doing in my life is more interesting than theirs. I think the opposite and would die to be in their shoes.

Huh. You'd think they'd just leave academia and go into industry after getting their Bachelors or maybe their Masters.

I mean, I'm fairly uncreative and conformist, but I noped out of college after getting my Bachelors and went right into industry. I'm currently more than happy working at an enterprise telecom in a conservative suburb, and I'm glad I didn't stick around in academia.
