wamatt··on Slack Acquires Screenhero (YC W13)
As a user of both Slack and Screenhero this makes me happy.

I've always felt they would make a cute couple. That said, integration seemed kind of sparse (limited to /username in Slack). We also struggled to have it work reliably in daily use.

Thus we mostly reverted back to the Skype/Slack combo. However this has proved to be suboptimal, partly because links and chatlogs shared in Skype are not archived in Slack for easy retrieval.

Hopefully this marriage will bring about a bunch of deeper and more polished integrations for users.

wamatt··on Wire – Modern Communications Network
To be fair, Slack is much more than simply an IRC clone
wamatt··on The world's smallest self-replicating program
I would think the opposite may be true, given that compressed information tends to be more sensitive to error, than uncompressed.
wamatt··on Pantelligent: Intelligent Pan – Cook Everything Perfectly (YC W13)
Love the concept! This would be perfect for someone like me, that likes to eat home cooked meals, but loathes the time it takes to prepare.

One thing however, I'm somewhat surprised to see no apparent mention of PFOA and PTFE being used? [1][2]

The price point of $199, puts this product squarely in the high-end of cookware, where Teflon based non-stick has fallen out of favor these days.

A smart pan that competes with Le Creuset's increasingly popular enamel pans, would be amazing. [3]

wamatt··on Pirate Bay Founder Peter Sunde Released from Prison
>The cost of 'specialty' food for a few tiny percent of prisoners is a minuscule figure in the total cost of imprisonment, and could easily be accommodated within the wider food offerings.

Agreed, this would seem to be manageable without much burden on the system.

On the other hand however, this reasoning discounts scenarios where inmates are pushing these subjective demarcations, for furthering their own needs, at the expense of being fair to everyone.

For example, in many states prisoner's may earn exemptions based off their religious practices.[1] If, an atheist prisoner, was denied sex, just because of their beliefs, I suspect they would have a right to be upset.

One should keep in mind, that it's quite possible to be supportive of increasing prisoner's rights and benefits, whilst also pushing for prisoner equality.

wamatt··on Lyft Accuses Former COO of Stealing Confidential Docs Before Joining Uber
Ok that was weird; tbh I'm genuinely confused. It would be helpful if anyone can explain what is so awful about my comment?
wamatt··on Lyft Accuses Former COO of Stealing Confidential Docs Before Joining Uber
Is it just me, or does Uber's behavior seem a bit Microsoft-in-the-90's?
wamatt··on Will a Breakthrough Solar Technology See the Light of Day?
While your critique is certainly true of the first generation of trackers, I'm not sure if you're familiar with a company called Qbotix[1]?

They're just one example where innovation in the space is producing cheaper and more reliable tracking. The basic idea is instead of having per panel tracking devices, rather, use a simple robot run around a fixed track and adjust the panels as needed. Then repeat again and again, throughout the day. If the robot malfunctions, swap it for the spare.

wamatt··on Plover: Thought to Text at 240 WPM (2013) [video]
Fascinating talk, thank you. I was curious, I saw it mentioned that stenographers have their own styles around the edges of the language.

Would it be possible to capture each users' idiosyncrasies, and work them in to the core to keep it expanding? (Perhaps using statistical analysis of shared chords?)

A goal could be to have the best of both worlds: flexibility to customize as one sees fit. Yet, also have the idiomatic ways bundled in. That way a user could minimize the amount of time spent tinkering, if they so wished.

wamatt··on Entrepreneurs think they’re badass
The author makes a familiar point, though it's worth repeating, if only as a reminder to stay humble.

That said, I can't help but recall a quote from one of the greatest pro golfers:

"The harder I practice, the luckier I get" - Gary Player

Note: the logic only flows one way, in that working hard does not mean one will be successful. Also, there are scant examples of self-made (eg. not inherited) successes without working extremely hard. In other words it's a mostly necessary, but not sufficient condition.

wamatt··on What Is Google Chrome Helper, and Why Is It Hogging My CPU Cycles?
Chrome actually has a built in Task Manager which can be super useful for this sort of thing.

For example, it allows one to see CPU & Mem usage per tab. It also has the ability to kill problematic tabs, extensions and background processes with ease.

Chrome's Task Manager can be found under Menu Icon -> (More) Tools.

In fact, this feature was being used often enough, that I ended up assigning it a shortcut. (for me: command-shift-1)

wamatt··on We Got Accepted into Techstars and Turned Them Down
Well, we both agree that high pressure tactics are not cool. Also encouraging startups to skip consulting with lawyers would be uncalled for. However on the second point, I can't see any mention of that. Do you have any evidence, or is this speculation?

In this specific case, I can see it going both ways.

So I guess where we perhaps differ, is that I would prefer to be certain of intent. Ideally, before reaching for the pitchforks to publicly shame someone.

wamatt··on We Got Accepted into Techstars and Turned Them Down
Not that I have any affiliation, though was curious. So I reached out to Troy on Twitter. He claims he extends more time if needed/requested, and they move quickly to close deals.

Is it possible, that maybe what transpired here, wasn't in fact a calculated tactic, designed to screw the applicant?

wamatt··on On a farm in Missouri, a radical experiment in self-sufficiency (2013)
They can both be, but there are two things to note. One is to make the distinction between being logical and being rational. So in this man's context I think it's fair to he may have logically coherent reasons for doing what he's doing. (ie it's internally consistent within his own framework).

However, I'd question the overall rationality of this. I mean we're on a path of accelerating technologization, AI, robots etc, and this guy wants to head back to the bronze age. So while there's a certain charming appeal to his vision, one should consider being a simple land dweller has traditionally not worked out so well, for those less advanced cultures. [1]

wamatt··on On a farm in Missouri, a radical experiment in self-sufficiency (2013)
One has to admire this man's grit, discipline and inventiveness. It's inspiring in a way, and makes you want to cheer him on.

OTOH, a part of me feels this effort more resembles idealism driven by a historical scarcity event. I suspect this emotional subroutine could be fueling his mission, rather than the logical post-apocalyptic rationalization he puts forth.

wamatt··on Using Machine Learning and Node.js to detect the gender of Instagram Users
> My guess is that gmail is using a linear classifier.

Yup, the Google "Priority Inbox" feature does indeed use a linear classifier, in particular logistic regression [1] for the reason of scale as you point out.

Also, IIRC Gmail's original spam detection used naive bayes. It may have evolved since then.

Congrats guys. It's been fun following your progress. Love the technical updates and overall direction :)
wamatt··on This Man Has Nothing to Hide – Not Even His Email Password
FYI, he's doing a Kickstarter to raise awareness and funding:

https://www.kickstarter.com/projects/noahdyer/a-year-without...

Philosophically speaking, the idea of a society where every actioned is monitored, recorded and made available, is a potentially interesting thought experiment.

That said, I find it rather difficult to feel too excited, for this specific campaign.

wamatt··on How the Napa Earthquake Affected Bay Area Sleepers
Did they really dispose any of the users data though? It appears they displayed a chart.

That graphic, it could be argued, is based on an entirely new data set.

So while individual data sets may been used at some point behind the scenes, it's not like those data sets are the ones being disposed.

wamatt··on Y Combinator And Mithril Invest In Helion, A Nuclear Fusion Startup
It's insanely cool that YC is now part of this. Also love that pg credits Sam for making it happen.

On a somewhat related note. Despite the setbacks and the bad rep nuclear gets, fusion really could be a better future. The energy density is in a class of its own, compared to that of renewables. Prof David MacKay demonstrates this quite effectively here[1]. This of course is not to take anything away from renewables or imply we shouldn't pursue funding both.

One group of companies I find particularly interesting, are those attempting aneutronic fusion.[2]

Like many good ideas, that became bad ideas (in the 60's), it appears to now be back in fashion.[3] Theoretical advancements have pushed the achievable temperature ceiling northwards, allowing a move towards commercialization.

Whether this particular line of fusion innovation will ultimately pan out, is perhaps anyone's guess. Personally however, I suspect there is a chance it can work. The benefits would be almost too good to pass up. Small, modular, cheap and safe (with almost no radioactive waste)

Some examples in the industry:

wamatt··on HTTPS as a ranking signal
The OP was referring to the webmasters, not the search engine end users, as the ones being 'dictated'* to by Google.

Unlike end users, webmasters themselves switching to Bing or DDG in their personal capacity would have little influence on their visitor's (end users) behavior.

* 'firmly encouraged' is perhaps more appropriate ;)

wamatt··on Show HN: QuoDB – Movie quote search engine based on subtitles
Nice design; fast and functional too. Kudos!

So while the fuzzy matching is neat, sometimes it's handy to be able to perform an exact search as well.

Typically this is done using "quotation marks" around the search term(s).

wamatt··on Ask HN: Should a fledgling SaaS website consider internationalization?
Good suggestion, Ty. We've at added support in code and data for the LTR languages.

While that means Arabic and Hebrew won't be supported without refactoring, it should be an appropriate compromise.

wamatt··on Ask HN: Should a fledgling SaaS website consider internationalization?
Yes, I'd agree with that.

In this case there is an established market (eg competitors) which would suggest there is ongoing customer demand. Whether visitors will like our service though is anyones guess, but we hope so!

We're placing most of our effort into making it simple to use, and helping users beam with happiness

wamatt··on Nukes of Hazard (2013)
Thanks for catching that. It struck me as odd too.

Disappointing to read needless hyperbole in the New Yorker.

wamatt··on Can Reddit Grow Up?
OP makes a compelling argument regarding the tensions between advertisers selling hype, and your average redditor's desire to tell it straight (anti-hype)

Here's an idea: there are some companies/services that are genuinely awesome and yet not marketed well. Now one may say they hardly need advertising because reddit promotes them naturally.

However, not all aforementioned companies explode and make it huge on reddit. So, what if you had a system whereby one incentivizes honest disclosure, whilst downplaying overselling?

In other words, a genuinely awesome small startup/service might submit itself and gain exposure (with full disclosure.) Upon a success, they would subsequently make a proportional payment for advertising to reddit, to help sustain the ecosystem.

It has parallels with a freemium model whereby some users (in this case successfully advertised companies) sustain the the others (non-paying users and companies).

wamatt··on Book review: Bad Pharma
>It's what doctors and patients said about knee arthroscopy for rheumatoid arthritus until they did a trial involving sham operations.

small correction; The NEJM studies (below), to which your comment was probably referring, were actually for arthroscopic surgery in osteoarthritis patients, not rheumatoid.

It's quite common to think these conditions are similar, but are really rather different, with diverse etiologies. RA is considered an autoimmune disease, whereas OA is not.
