I help non-technical founders handle their tech so they can focus on growth.

If you're a B2B startup founder struggling to stay on top of your design & development processes while simultaneously juggling your business's sales, marketing, and operations, I can help.

Over the last ten years, I've contributed to over 25 products launched across app stores and the web. In that time, I've worked with Fortune 500s as a consultant at Google, with venture-backed startups as a partner at Gradient, and with non-technical founders as founder and project lead at SANE.digital.

As soon as next week, I can join your team as an independent technical co-founder, taking over your design & development processes and freeing you up to focus on the only thing that matters to an early stage startup:

Growth.

Don't just take my word for it. Listen to my clients:

“James understands what it means to work with a startup where every dollar counts. Thanks to him, we were able to bring our products to market much faster than we could have ourselves.” - Matt Ivester (CEO, A Rad Corporation)

“After three years of other agencies promising a lot but delivering little, getting to test a prototype after just a few weeks was very cool. From the first time we sat down, I really felt James got what I was trying to do.” - Andy Lin (Founder, Self Portrait Project)

“After an entire year of working with another firm, our app just did not work—the core feature was broken and the app drained the battery. James was able to research the problem and find a workable solution in a matter of weeks.” - Lachie Given (Founder, Knowhere)

What's the problem you are trying to solve here?

In general for the kinds of problems that intersect with economics, taxes are more efficient than outright bans.
See above comment for a great example of a perfectly executed HN joke that will not be hated/downvoted.

The bulk of the comment is not the joke, both in number of words, and ideas.

This would not only get a pass, but it would likely be recognized as a great comment in a more popular thread.
I agree on renewables and they are certainly part of the solution, but we can meet our energy without fossil fuels if we really leaned into nuclear the way the French did.

It's simply a matter of political will.

Musk looked at the regulatory tape around nuclear and said "I guess it has to be solar then" and I think that was a mistake. If we'd applied his economics of scale, and first principles thinking to nuclear we'd be far, far more along than we are right now and we'd probably have more medical isotopes to boot.
Just a few low-activity OS & mostly sleeping application threads will barely fill one or two of these typical 'slow' cores you see in big.LITTLE SoC's, so what's the point of adding more of them?

I don't think lack of general-purpose cores has been a problem for mobile for a long time. I see much more value in heterogeneous SoC's that integrate multiple application-specific blocks that can only do a few things but do them very, very efficiently. This is pretty much what the industry has been moving towards for the past few years anyway, the Apple M1 being a good example of that.
Right? Its pretty crazy. And extrapolating further, you can show that the concept of private property is what necessitates tax, since the modern state is in large part an apparatus for enforcing the concept of private property. Therefore libertarian complaints about taxation quickly fall apart under close scrutiny.
Bada bing, bada boom. I used to work with GIS data quite frequently, and I probably used this at least once a week at the time.

Reprogramming to recover youthful epigenetics and restore vision (in mice)
A new paper is out from David Sinclair's lab yesterday. They used an adeno-associated virus to overexpress OCT4/SOX2/KLF4 (three transcription factors involved in pluripotency) in the mouse retina. They found that this caused it to regenerate after damage, and they also suggested it might be used to reverse aging.

Safety concerns (e.g. teratoma formation) are only briefly mentioned. They write that, "After 10–18 months of continuous OSK induction, no increase in tumour incidence or negative effects on overall health were observed" but if this were to be used in humans, much more rigorous safety studies would be required.
Jailhouse: Linux-Based Partitioning Hypervisor
> if the report is correct and HD video streaming on a phone generates about eight times more in emissions than standard definition, then it is the kind of thing that service providers should be thinking about when developing services.

Because if it contributes .01% to climate change (the number is made up since the article doesn't actually say), then you're making a relatively significant inconvenience to yourself for a benefit that is entirely dwarfed by someone taking an extra plane trip.

Someone quoted in the article says as much.

> Another co-author of the report, Prof Corinne Le Querre from the University of East Anglia, told BBC News: “To be honest, digital tech is a small fraction of your emissions compared with, say flying even once a year – but every bit of CO2 saving is significant. [emphasis added]"

This is not a rational statement in the slightest. Most religious dogma is more sensible. There exist vast swathes of "savings" that are not significant (including, IMO, watching SD video). It is in fact counterproductive if it means that people sacrifice in a variety of ways to fulfill their mythic "every bit of savings is significant" duties while taking part in behaviors that contribute to climate change. (And this ignores the central dogma that all climate change is necessarily destructive and will have no benefits to humanity or Earth whatsoever.)

My favorite nonsense recommendation in the article is to run all computing in the cloud - I guess the Google donation is paying off[1]. ARM is listed as another donor, so if Apple joins, expect buying M1 Macs to be yet another way to help the planet! Sarcasm aside, we could consider things like nuclear energy, traveling by train (it's quite affordable and enjoyable), "trillion tree initiatives," and a host of other programs that might actually make an impact assuming climate change seriously concerns you (it's only of mild concern to me).

This is great, though I wonder what we would do about laminates. For example, a can of cola has a plastic lining to protect the aluminium from degrading, tetrapak containers are laminates to prevent leakage, counter tops and flatpak furniture tends to be plastic-wrapped chipboard.

A lot of these laminates can be replaced, but some are rather harder to. Progressive taxation based on recyclability is an easy win which incentivizes correct packaging (and transport packaging as well) and would be an easier sell.
Additional, homogeneous packaging would be taxed less.

The branding that goes on the packaging is still open to design, so there's room for differentiation there - a necessary component for adoption.

Lastly, standardizing recyclability across the state/county/country would be useful as then tourists etc. can also understand a simple recycling message.
The angle measure i acos(x) is the logarithm of the rotation x + i√(1 − x²).

If you want to compute the product of two rotations, you can take logarithms and rewrite it as a sum of angle measures:

[x + i√(1 − x²)][y + i√(1 − y²)] = exp(i acos(x) + i acos(y))

[x + i√(1 − x²)][y − i√(1 − y²)] = exp(i acos(x) − i acos(y))

Now if you just look at the real parts, you can write:

xy − √(1 − x²)√(1 − y²) = cos(acos(x) + acos(y))

xy + √(1 − x²)√(1 − y²) = cos(acos(x) − acos(y))

Taking the sum on each side:

2xy = cos(acos(x) + acos(y)) + cos(acos(x) − acos(y))

This method is rather more cumbersome (due to rescaling and then converting the factors to rotations as an intermediate step) but fundamentally based on the same concept as:

xy = exp(log(x) + log(y))

It'd be nice to work for an org like that.

My entire career, any performance tweaking has had to be skunkworks, has never been rewarded.

At my very first tech dev job, my coworker and I speed up a novel workflow, as in brand new technology (think OCR for blueprints), about 4x faster. Made our new service practical. We were so thrilled. Boss man was unimpressed. "You should have thought of that before." I'm still angry about it. Clearly.

Ok. Wait. That's not entirely correct. A recent team did claim to have targets for P90, P99. So we measured. But it wasn't systematic, nor global. None of the other web services (teams) bothered, so our effort didn't actually matter. And even then my team wasn't willing to sacrifice our sacred cows to consistently attain the P90, P99 targets.
You can speak out anonymously in media interviews. Ryanair pilots do this frequnetly when it comes to unions/working environment...
And that is exactly why blaming individual behavior is so harmful. Everyone is solving the prisoner's dilemma by playing tit-for-tat.

If your neighbors cheat by emitting more carbon then you will eventually start cheating as well. The only way to solve the dillema is by ensuring that people can't reap the benefits of cheating.
Bad title. It's not mushrooms but "some fungi".

It's pretty normal for lower complexity cores to be more power efficient than higher complexity cores. Many structures in a processor scale as N^2 with width in terms of both transistors and power usage.
I've seen Soviet-era posters with his birthmark airbrushed out, so I guess it's possible.
FYI, I cannot find a source report for this. I would expect better from a UK accredited charity with "Royal" in it.

Why no link to source? Or numbers? In an era of "fake news", does traditional media not differentiate itself by providing those markers of quality?

The last report I saw on this theme credited half an hours' netflix with 1.6 kg CO2 emissions, by "the Shift project". With a typical grid, that's 4 kWh in half an hour, or 8 KILOWATTS to sling video. By their own emission, they overestimated by a factor of 8 (https://theshiftproject.org/wp-content/uploads/2020/06/2020-...). Even after that they're still an outlier. About the only thing vaguely correct is that mobile data does appear much more intensive than landline.

Knowing CO2e per GB would be useful (possibly CO2e per GB.km). Unfortunately, and inevitably, the space is filled with bad actors. The BBC should know better than to give them oxygen.
Script to paste clipboard contents into a VM without guest utils and data leaks
I hate having to install VM-specific guest utils all the time when I just want to paste some text into the VM. Here's a script that emulates keyboard input and just works. ASCII-only, sadly.

Also, in VirtualBox, when you turn host-guest clipboard sync on in the VM settings (or set it to "Bidirectional"), it automatically syncs host clipboard contents to the VM clipboard, even if you never actually paste the clipboard contents into that VM. If you're running untrusted software in a VM and have guest utils installed, this might be a data leak vector you're not even aware of. So, install this script and only use guest-host clipboard sync if you really need it.
What may be easier is to move the heating element to the top, and add a pump to move water to the top when heating.

Hot water will stay at the top of the tank, so that means you can use most of the hot water without a significant drop in temperature.

There's a company making tanks like this: https://www.youtube.com/watch?v=z1Z4JCoPAGc
You run into diminishing returns with screen and radio power on a cell phone pretty quickly. If your phone is sitting in your pocket in airplane mode those aren't a problem, of course, but your processor will be sleeping then anyways.
The parameters matter a lot though. With social distancing/mask wearing there is a very measurable risk that's immediate to you and the people around you. With climate change your actions make a tiny tiny impact that's spread disproportionately over the entire planet and takes effect over decades - this makes it much easier to ignore.

If people could get infected with climate-change disease and x% of them die, there would be a lot more action to prevent it.
What's the best way to scrape Yelp listings to .CSV? – JustPaste.it
Why would they have to? Not all the best engineers are on Silicon Valley, and many who are would gladly move out.

Sure, they won't hire the ones who are there and not willing to move out but that's probably a small pool compared to the rest of the world.
I don't see why not. Renewables already means periodic negative power prices for most countries that have them. They will likely use this electricity to make these chemicals closer to where they are needed. This is already happening with aluminum in, e.g. Germany.

Even if they don't, 1/3 of the countries in the world are drenched in sunlight. The competition will make margins on these industries pretty pitiful.

>- Developers don’t want to write css so they add insane amounts of nuisance in templates. Impossible to read the design language.

I don't think this premise is very shaky, unfortunately, if it was shaky I doubt we would be seeing all these solutions coming around trying to help developers avoid writing css, solutions which seem to have uptake in the market.
I've seen surveys that have open fields like that before but they usual use some keyword analysis to distil the results down (though I've always been sceptical how well their NLPs interpret messages like "I always use for personal projects" and "I never use for personal projects" as polar opposites despite the similar wording).

Anyhow, in this instance you're right that there isn't even a need for open fields, there's enough examples online already of IT being separated into distinct sectors for field selection on forms.

But what really grated me the most about the results was that there didn't even seem to be any deduping of the results (or if there was, it was case sensitive):

("Everything" "everything")
("Personal" "projects")
("web development" "Web development")

And there was even an instance where prototyping appeared twice because one instance had \s afterwards!
> The Chrome team has considered removing Push support since at least 2018. The main reason being that they hadn’t really seen the performance benefit for pushing static assets.

Because they probably benchmarked Google properties that are already using something akin to HTTP/2 Push, because they are inlining a lot of their assets and data.
Oh, good to know. But then it wants me to create a Hue account and link that with Google... which I don't really want / care for. So I'll be sticking with my widgets.
“No one in the organisation will be able to use productivity score to access data about how an individual user is using apps and services in Microsoft 365.”

How cute :) Organization don't get it. Microsoft get it all for itself :> More data for the ads ! And not only that.

All that experience or even code done by MS for China scoring system must be enforced on the rest of Earth population !

Not to mention typical metrics stupidity: lines of code, keypresses, count of videocalls ?

Such thing is just proof to not use that online-desktop apps. Or straight outlaw them.

But managers will love it ! Just today news: Google spies on emploeyes before firing them - no more "spying" necessary, everything will be in the "data" ! :>

"Decompose" would imply they also break down toxic chemicals, which would be even better - do they actually do that?
If it’s any consolation, the US has increasingly moved its diplomatic channels out of their traditional venues into the Pentagon over the past few decades, and it’s absolutely packed to the gills with Vindmans and Hills.

While the State Department might get a new coat of paint under Biden, it’s been being “gutted” for decades.
Nice post! Thanks
They are getting paid to research different ideas so thats why they might be proposing ideas you find to be misguided.

There are instances where researchers spend their time where the outcome was mostly thought experiment / not directly applicable, and there are instances where the work was useful from an application perspective. Such is life
GDP per capita is a measure of consumption. Consumption has increased on every continent bar Africa since WW2. People are a lot less poor.

If you want an illustration of this look at this graph of the cost of 66 technologies dropping over the 1951-2013 period. That’s people getting richer.

https://ourworldindata.org/grapher/costs-of-66-different-tec...

This is increases in broad based prosperity, the same kind of thing we think about when we consider how antibiotics went from cutting edge technology to ho hum, or how air conditioning made large parts of the world amenable to industrial civilization. You know the kind that reduces poverty.
> Okay, and what good are those features if users are afraid to run the app lest it eat all their RAM for breakfast?

There is no evidence to believe that users are concerned about RAM usage to any level that would move them over to competing apps.

> The "work faster" argument is pretty dubious on its own anyway; yeah, maybe web devs ain't particularly productive with Qt or similar frameworks, but desktop devs absolutely can (and arguably should) be productive with such a framework.

There are orders of magnitude more web devs than devs who are even just familiar with desktop GUI toolkits. Even if you can find people who are just as productive with (for example) Qt, they'd be (way) more expensive than the average web dev.

And, again, now you have less budget to spend on things that actually gets you users.
I only just realised that the character Arkady Bogdanov in Kim Stanley Robinson's Mars trilogy was named after this author!
>Could you explain where is multiplication in cases below?

There's some confusion in this question. A log normal distribution is proof enough that multiplication exists.

3 and 7 are trivial because there are clear compounding effects - they are most obvious in finance. 5 is easy too, more rainfall means more water evaporates, it's a simple multiplicative cycle. 1 because larger response is more likely to generate more larger responses.

There's no causal relation between multiple factors in block propagation. It snows and latency to starlink rises. There's congestion somewhere because a new tv series is being massively downloaded. A node has random clock skew of 1 s. These are all additive.
I think 2-5x the cost, 10-1000x the capital intensity, and the industry's demand of a $200 million liability cap to make plants insurable.

Maybe if we had adopted nuclear en masse in the 80s we could have avoided current climate issues, but we didn't. I don't see why anybody thinks there's any point subsidizing this industry to hell and back now given the cost and the cheaper, less capital intensive options available that don't need subsidies.
Yes it has improved a lot. Still more improvements to come!
> if I want to look down

then you move the joystick down. That's the rationale for us non-inverted Y players :-)

The inverted Y would make more sense if they also used inverted X.
As an even simpler example, hydrocarbons can be burned to water and C2O. You can feed those to plants just like anything else.

(But going that route would waste a lot of energy.)
Why would you want to do the Machine Learning within the DB anyway? To me this looks like rather a corner case. E.g. I usually want to scale my MLE infrastructure independent from the DB. To it seems much to pipe the Data into log like Kafka to compute the result, just because that is much easier to scale. Similarly for training it seem to be that using some files on an Objectstore as the input is usually much easier to scale.

I would call this “being so skeptical that your brain falls out” since you could make the same argument (about either politics or money) with scientists, human rights advocates, programmers, etc. “Actually you can’t trust anybody and all viewpoints are equally suspect” isn’t as enlightened as you think.

In this specific case Apple and Samsung have been proven dishonest and manipulative, and they have a far stronger legal/financial incentive to lie than separate groups of prosecutors in the US and many separate EU member states. I also find a conspiracy internal to Apple/Samsung much more plausible than a conspiracy across attorneys general from 34 US states.
As I said before: technicalities don’t work. You’re not getting out of this. If you told the judge that, he’d change his order to hand over the data in a different way. Have fun sitting down with the police while they copy all of the data off by hand while you show them each item.
