Show HN: Soft-launch, first page on HN – here are the numbers
[1/2]

Thursday evening (Mar 26) we made a soft launch for https://uidesigndaily.com (a UI website that I built for my wife)

The goal was to get some feedback, fix bugs and get about 30-40 subscribers in the mailing list, to see how the newsletter performs.

The launch went better than expected, and the feedback was generally positive.

Below are some numbers for those interested.

I posted it to 4 channels, IH, HN, Reddit and Twitter.

It was best received on HN with 203 points, it made it in the top 10, and it stayed on the front page for a good while. Reddit also surprised me, I posted in r/SideProject and got 26 upvotes and only positive comments.. ? That is so not what I expected from reddit... Was very pleasantly surprised to say the least.

- Mar 27 - 3693 Users
- Mar 28 - 706 Users
- Mar 29 - 186 Users
- Mar 30 - 190 Users

As you can see, there’s been a spike and seems like it’ll stagnate around ~150, but it remains to be seen. It might dip even further.

Newsletter:
- 546 Subscriptions
- 52.1% Open Rate
- 6.7% Clicks
- 7 Unsubscribes

Slack Community:
40 Members. Interestingly enough, the Slack ad only received 30 clicks total. This means most users came through the welcome email, which has a slack community ad included.

Ad Performance:
- 35744 Impressions
- 836 Clicks on Website

It's not end to end encrypted, and it apparently has the charming people of saving other people's "private" messages in the minutes if they send them during a meeting.

Why did zoom suddenly become so popular? It's not like there's a shortage of options.
[2/2]

Feedback/Critiques:
- Make the ads more distinguishable from the designs in the gallery.
- Subscribe popup on the post page comes in with delay and is annoying.
- Developers do not understand the software icons listed, they need labels.
- There was some confusion about the “open-source design” term, somebody thought it is created with open source software, instead of the design source file being available.
- Some developers don’t know how to open the source files. A tip should be included that Figma is free and it opens up most file formats.
- Find a license that is more in line with our permissive approach. Maybe public domain?

Bugs:
- 13 different bugs found in production
- 79 total errors thrown in production
- 27 users experienced issues in production

Operational Cost:
- $8 - $13 per day, most of which is egress traffic and server log storage.

Conclusion:
The soft went much better than expected, and it revealed some interesting insights about this project. We are going to make all the requested adjustments, fix the bugs, and prepare for the official launch.

1 km = 1000 m

1 m = 100 cm

1 cm = 10 mm

That said, it would be nice to see a generation of fractional numbers to just re-align... 4x50H/U for the refresh, then next generation, just wait.

It's far more about marketing... 4000 is higher than 3000, but you'd have to know there are no 4000 desktop CPUs when shopping, so it still creates confusion.
There is also no need for a central standard. My company just took an existing CSS framework (it doesn't matter which framework) and then slapped their own customization on top of it and then reused it in dozens of applications. Not much time was actually wasted on the design itself.

>• Beer served in pints by on-licenses, millilitres by off-licences

Sure but a pint is defined as 568ml. The only one that really is quirky is how people haven't yet grasped kilometers yet they're the easiest to grok, it's just 1.6 * miles.

Maybe Gitlab should also stop seeking profit from their project software.
... and maybe a certain charm. My VHS collection implies there must be some charm to VHS - and a grainy meme clip with 100% guarantee of no sound has a certain charm too.
Code availability is important too though. I'd much rather use something that had code available (e.g. Unreal Engine) than something that didn't (Unity) because sometimes things aren't documented and you need to read the source to find an answer.
Thanks Dude!
The goal of this is to spark discussion about everyone creating their own app at the moment. I want to explore the idea of existing applications enabling such a feature (opt in of course).
Canada has gone mostly metric, now, but growing up on a farm a few decades ago, I definitely got a hybrid. People's heights and weights were imperial, other things were mostly metric. Gravel roads were miles, highways kilometres. Oven temperatures were Fahrenheit, human temperatures Celsius. The really perverse one is that when referring to gallons, we had to specify US or imperial.

Honest question. Why not just completely outlaw code like:

Thanks, this is good but it's not for me.

> Your project must not seek to make a profit from the resulting project software

My project is my job, it's OS but I need to profit from it. I don't mind paying, but just per project. I just don't want to pay for the thousands of people on it who's just making spelling corrections.
It can be done, but most people, who don't work at just one desk prefer the laptop as you can quickly move it to a meeting room etc. When you move the small PC, you not only need to carry keyboard and mouse and have a screen, it also means restarting the machine. A laptop keeps running and has almost everything in one package.
This is going to sound subjective, but: you can't claim that something is a good desktop-app building experience in 2020 and lead with something that looks like... that.

Browsers have simply set the bar too high.
Similar thoughts here... and the single memory slot upgrade to single channel and only 24gb is a non-starter. My work laptop has 16gb and I'm running out regularly, but the performance drop for single-channel mode is unacceptable imho.

Would like to see this with a dual-slot memory access and up to a 32gb model at the top end, upgradable to 64gb would be nicer still. Dropping the GPU in favor of just the APU would be an option for me as well, I don't play games on the work computer, and don't use a GPU in a meaningful way.
The Mathematics of Predicting the Course of the Coronavirus
We know they had a larger brain volume than us, even when correcting for overall body size. That much is an established fact. What that means, if anything, regarding their behavior & abilities is strictly, and highly, speculative.

(Still lots of fun to think about. If I were to hazard a guess, it would be something along the lines of greater neoteny in h. Sapiens sapiens. For an analogy, compare dogs and wolves. Wolves have larger brains, but dogs have a greater ability to read social cues.)

The private message thing was completely overblown though, wasn't it?

From what I understood it only saves your own private messages in the log. So the only time you could get in trouble is if you exported the log and then shared the file with others without removing your private messages. So just like you took a screenshot and didn't censor the parts you wanted to keep hidden.

Hardly the massive scandal that some people on Twitter seemed to try to make it.

The metric fuel efficiency measure is litres per 100km.

Video/sound quality is much better than any alternative I have tried. You can see video from up to 25 (or even more now?) people at the same time. It's easy for people to set it up and join meetings. Easy to share screens/audio.
Sure but a pint is defined as 568ml.

. . . which I have previously determined to be within 0.5ml of the traditional volume.
The project started out a bit more ambitious (creating yet another tracing app), I guess it was good that from the 20 people who wanted to contribute only 2 were left actually doing work, so we had to make it as simple as possible. I hope others will create SDK's so other devs can easily integrate it into their apps.
It works.

I tried multiple other tools over time, zoom was the first one where all attendees had it working on all systems without problems.
From my personal experience with one of the above, you can't get hired as remote, but if you are considered a "top-perfomer" (i.e. regrettable attrition), then you can probably pull it off.

I don't think this is the right mental model of coding.

It seems a bit too similar to the idea that "most people simply cannot read".

We all accept that nobody can read without instruction, practice, and feedback. Why is coding somehow different? If anything, I think reading is more foreign/difficult, because coding is explicit thinking, and we all think. Whereas reading is a completely synthetic act that starts with arbitrary symbols that must be memorized by rote before you can even take the next step of using them.

None of us start out life being literate, but few people lack the ability to become literate. Why is coding different?
I'm surprised an Indian person has used US units

How long does it take immigrants in the US to "go native"?
Personally I found that my productivity as a software developer was much higher when I was young and didn’t think so much about the cleanest code or the perfect architecture for a problem and instead just tried different approaches. Now I often feel paralyzed by having to “get it right” from the beginning.

Valid (in my opinion) lessons I cherish today are keeping individual parts of a code base simple and understandable, documenting and testing a lot and preferring simpler solutions over complex ones.
You got it wrong. Airspace over cities is very limited. At some point you get to the height in which long distance flights travel.

It's possible it has fallen out of favor. I'm a tad on the old side.
That's quite a lot considering that nature of the platform. It explain why most of the stuff I see these days seem to be more small commercial classes rather than just the meetups that it started as.
In an odd way, the US is fully metricized: they’re one of the original signatories of the Treaty of the Metre, and redefined all of their legacy units in terms of SI ones [1]. SI units are used directly in the sciences and most products have the SI equivalent listed alongside the traditional measure. I understand that industries with international supply chains, like the auto industry, are also mostly metric these days.

There just hasn’t been much of a reason for the purely-domestic parts of the market to switch: house builders are looking for 2x4 lumber, and won’t buy from a lumberyard that calls it 50x100mm. Knowing that, the sawmills continue producing the 1.5x3.5 inch profile that’s called “2x4” and anything else is a specialty item. Who has an incentive to push through the change?

Hm, as far as I know, the problem most people have with Electron is not around the language, React or bindings but the fact that there is a embedded browser in there that adds a lot to the size and memory consumption (and security issues).

I'm curious to hear why you're glad we're going away from Electron into something that seems to be about the same thing, albeit a different language?
On one hand it looks really cool, on the other hand it gives me flash-era flashbacks. But he is not trying to pass this as an useful homepage to unsuspecting small business owners who should know better, so I guess this is fine.

A decade is not enough in my experience. I think the answer is never.
Both "dumb" and abstracted code can be hard to read and change. The most important part is consistency.

It is generally easier to write dumb code that is consistent. It requires less mental energy and is often a very good starting point for refactoring into something more declarative and DRY.

The pain comes from inconsistent code, often either based on wrong previous assumptions, premature optimization or time pressure.
The Fizzbuzz test sounds like a joke when you first hear about it, but it's incredibly effective at weeding out these people.
It's not distracting - it's actively helpful. It helps you understand how the parts of the user interface are separated, and so guides in how to interact.

I yearn for the menus of Windows 98 whenever I'm forced to use a new/updated ios app, and don't understand where to swipe to get it do to what I want.

Back then, software even came with manuals, and often a useful "help" menu right in the application. Now, when you google "how to x in app y", you end up on some spammy help-page that spends 5 paragraphs (with ads) to tell you to "pinch and then swipe" or whatever.
I wonder if anyone has tried cljfx->Android with Gluon's stuff
Agreed.. would love to see some Ryzen 4000 options from System 76 and Dell.
Just saying 100 tabs = 1.2 GB or 10 tabs = 2 GB doesn't make much sense as it depends on a lot more things than just the count of the tabs.

You'll need to also outline what pages are in those tabs, how much each tab consumes, what extensions you have installed, how your config looks, what your OS is, how much history you have, what is your usage pattern, what experimental flags have you/the system activated and more.

It just depends on so many variables. 10 tabs of CNN is gonna use way more memory than 100 tabs of Hacker News comments, as a basic example. But you have a content script that is injected on every HN page with live feeds of something, now 1 HN tab might use more memory than 10 tabs of CNN.

India is a Commonwealth country, and I wouldn't be surprised if a lot of people still think in imperial (not US customary) units.

Also, here in the UK, for the purposes of identifying COVID-19 symptoms, a fever is being defined as 38.6 °C = 100.0 °F, so US recommendations are clearly having an influence in other countries.
> Once the JVM has allocated heap space it will never let go of it.

While this used to be true in the past, some of the GCs available to the JVM may now uncommit heap memory. This is for sure the case with ZGC [1], G1 [2] and I think also with Shenandoah [3]

Disagree. I think GP is correct: most of the market value of paintings is in provenance of the physical object.

The "nexus point for many values and inspirations that speak highly to the culture that produced them" is fully encoded in the information content of the painting. With sufficiently good copying techniques, a physical painting can be copied or digitized while preserving all this. After all, whenever discussing "values and inspirations", you're usually not staring at an original, but at a cheap photocopy in some book or on a webpage - and yet the "values and inspirations" get communicated and discussed.

The aesthetic value is indeed only the part of a work - but again, contained within the information content. This includes provenance of the information. E.g. you derive joy from knowing this image was painted by Picasso, even though you're looking at a compressed digitization of a copy of a copy of the original painting.

GP's proposal would crash the art value to aesthetics + "values and inspirations", letting the culture partake in it better, and cutting out the scarcity.

Last time I tried, cljfx (actually JavaFX in general) doesn't play too nice with GraalVM, I'm not sure Gluon actually addresses that, so it'll be hard to add another layer (Android) when the basic layer doesn't work.

> One of the nice things about IPSec is that it's a standard

I would love to agree with this, but in practice, IPsec across vendors (or even across product lines from the same vendor) is often a nightmare. There are so many moving parts to IPSec, whereas Wireguard is drastically simpler.
> and the imperial part there for old people's convenience.

And also because that's what was used to actually design the container. Milk bottles in 1 / 2 / 4 / 6 pints (imperial pints, not US pints), 454 g jam jars.
Interesting. Thanks a lot for sharing that, it seems to indeed confirm the birds were much braver than I thought.
> so how could Git have succeeded because of Linus, other than Linus originating the genius design of it?

Perhaps that is exactly the point. There was a fair amount of hype and press coverage over Git when it was first unveiled. And it was because Linus wrote it, and wrote it in an unexpectedly short time. And it was on the coattails of the whole Bitkeeper saga.

This invites the sincere, honest technical inquiry as to why OpenBSD doesn't have an SELinux-style Mandatory Access Control (MAC) facility, but is OK with the traditional Discretionary Access Control (DAC).

You are ignoring the fact that cars have to navigate what is basically a set a of 1 dimensional corridors on a 2 dimensional plane. Airplanes don't have these limitations and can fly point to point at their choice of altitude.

Currently most of the congestion in aviation is around airports which are necessarily optimized for large jets. With a small airplane, you can fly to a much larger variety of airports, around ~50K world wide and it's relatively straightforward to build even more of them as needed.

Noise is a function of propeller size, rotation speed, and engine noise. Simply put, lots of small propellers rotating at faster speeds driven by electrical engines are a lot less noisy than larger props driven by combustion engines. The physics around this are complex and involve things like the speed of sound of the tips of the propeller (you break that limit at lower rpm for larger props), the mass and thickness of the propeller, vortices, etc. Basically, all of that improves with smaller props.

Compared to a loud helicopter, an electrical plane at the same altitude could be a lot less noisy to the point where in a busy city you'd hear one but not the other above the ambient noise.
>It can never settle into a steady, viable state where it just does its job.

I agree with your argument that numerically, playing the odds make sense, but I don't see how this necessarily rules out the possibility of settling into a steady business if that's what the company's owner(s) want.

Especially with the backlash/burnout from VC demands, it seems to me like there would be plenty of business owners who would prefer the stabler "lifestyle business" over the moonshot because for emotional reasons, they prefer to leave potential money on the table in exchange for stability.
