We're able to recognize simple ratios instantly. The fact is without number the actual digits, we know they instantly simplify into a handful of fractions. That is mind blowing.

What's even more mind blowing is Adam Neely's explanation of pitch ratios and how they're related to tempo. The short incorrect explanation is if you layer beats 4:4, 5:4, 6:4 ratios (which is the ratio of pitches against the root in a major chord), then speed it up to a ridiculous frequency, our ears hear a major chord. It would seem that Tempo and Pitch are very much intertwined and our brains decipher that very quickly without evening consciously dividing the frequencies.

Mistakes to Avoid When Choosing Your Logo Colors
Why does this matter? Users don't care and its easier to remember/understand that all websites are just "x.com" rather than sometimes being "www.x.com". If you have some server/troubleshooting/network/dev problem with it, the missing info should be moved to developer tools.

This is just removing data that is useless and confusing to 99.9% of users - whats the problem?
As the article mentions, lotteries protect themselves by making it logistically impossible for anybody to buy every ticket.

I wonder why they care. In fact, they need someone to win big, so as to entice future players...
This is so frustrating. I keep trying to use Safari just for this alone.
I am a big fan of dbt, and I believe they are on something really good to transform modern BI and data analytics
This is only visually what's displayed in the address bar, similar to how they started dropping http/https from the start of URLs a while back.

While I'd personally disagree with these kind of changes, and I would always prefer it to show the http/https and the www dot, it doesn't actually break things like copy and pasting the URL from the address bar. You still go to www.google.com when you type in www.google.com, it's just trimming away the www dot displayed in the address bar.

I think for the vast majority of non-technical people it's not really going to make even a little bit of difference. If anything it'll make it easier to spot what domain they're on, assuming they're even checking to begin with.
A saber is a type of sword. It’s pretty heavy and was meant for use on horseback (i.e. cavalry).
No, but Visual Studio (not Code) is rapidly integrating R# features into VS. Many people are disabling R# because it slows down VS so badly and Microsoft has been closing the gap (see recent 15.8 release with EditorConfig features).
plz stop.. PD should be a cash cow, stop 'innovating' and 'growing', just deliver what it says on the tin. Over the past few years I've been using PD it is becoming worse and worse, it seems to me because they have to keep their developers busy.

They could of course just make the core product better, but thats not cool enough i guess.

My colleague and I started the sales team at PagerDuty. We were both engineers. Happy to meet for coffee in SoMa if anyone with revenue would like a short 1:1. I've done this a number of times over the years and hopefully those folks have found it helpful.

Sorry, no remote/phone calls. I don't do calls with clients either - face-to-face only - lesson one :)

I'll add it to the list, thanks!
Wasn't this (partially?) solved by making the domain black and the rest of the text gray? That's how it appears in Firefox. It makes it very easy to see "ycombinator.com".
ideally it means no passive snooping
Photoshop had non-destructive editing for 15-20 years.

I think the issues are getting confused. Yes, Lightroom saves a separate file from your photos of the changes so in that sense it's non destructive, the original files are not changed.

Photoshop is non-destructive in that you can load an image into a layer and apply tons of layers above that layer each of which edits the layers below it in some way. The pixels in the image layer are never changed so it's also "non-destructive". But saving the file does overwrite the old photoshop file with your changes, unlike lightroom.

Amazing how a relatively niche product like this can have such a huge valuation. Shows how big the market is.
99.9% of users have no idea what any of the words you just said mean. The change was made for them, not for you (the .1%)
If you're an early-stage startup that's still determining product-market fit, then it's completely fair to eschew tests and accumulate tech debt; you're at a higher risk of running out of runway before you've even proven that your business works.

As soon as you have enough users that an outage poses a significant risk to your business, you need to invest in either refactoring to reduce tech debt, or a rewrite. And you NEED to add tests, and a robust deployment process that tests changes at multiple stages with monitoring on the basics (server speed and memory usage, database error rate, etc).

OKCupid got lucky in this case.

Simple save does the same function in Corel in general. It isn't that it isn't a photoshop clone that is an issue, though for a slew of folks, they are using it as an alternative.

When x is standard workflow for many of the other such programs (and things like word processors) and it isn't such in Gimp, that very thing drives people away. Most artists aren't going to care what the software engineers want in the program: Instead, they are going to care about things like this. When added up, it just makes for a frustrating experience. It doesn't really matter what the technicalities are if you are the artist.

Yes, you do lose some information depending on the format. Heck, I notice loss simply looking at an image on different screens. The fact is, though, that folks actually need to save in different formats. Sure, I keep my layers and information in tact while working, but folks also need to be able to share their work, print it, and things like that. For that sort of thing, you need the different formats. The exact format depends on what one is doing: PNG works for facebook and instagram. Some sites have file size limits, and with some printing you have a bit more leeway.

I'm not even a photoshop fan myself: I chose my software based on both if it was easily integrated with a Wacom pen display and how well it mimicked traditional artwork flow and styles. Hence my use of Corel. Photoshop is basically a renting program now, and I generally welcome alternatives. Gimp has always been somewhat frustrating because of little stuff like this.
ROS can be an super enjoyable and productive environment to build software in. It gives you access to a set of common sensor and actuator drivers, motion planning, navigation, perception libraries, and implementations of the latest IROS papers. I’ve seen it used to prototype lots of non-robotics applications too; really any local distributed system integrating, calibrating, and coordinating sensors. Personally I think the standardized data types it provides for robotics and perception data is one of its greatest assets [1], and could be a standards effort in itself. And it’s home to a great community.

But it definitely has its limits, especially as applications mature, and the ecosystem can feel siloed from the technology landscape evolving so quickly in, for example, backend distributed systems. Knowledge transfer between the robotics community and the software engineering happening in distributed systems, databases, gaming, web development, etc. is a huge untapped opportunity. Hit me up if you want to talk more about this!

Why does www matter?
I have an iPhone 5s still working fine, released in 2013..
Just updated to see it in action. Seems like a nice improvement for end users. Don't think there is any reason not to do this, other than a nostalgic desire for things to stay the same. Most sites already have a www. to . redirect in place and if you don't its a trivial change.
As true as this is, hiding the "www." subdomain isn't the right solution.

For starters, it doesn't work for non "www." subdomains, for example... news.ycombinator.com isn't protected by this solution.

A better solution IMHO, would be to do it like firefox, grey it out.
Of the reasons I'd buy for Google being incentivised to do this, preventing spearphishing would be low on the list.
(Off Topic -- Rant regarding Webpage)

Can I take a short moment to bitch about "sidebar" frame or whatever the hell this domain is using? The webpage looks like a fluid single frame but the left side is static. The browser page has a scrollbar but I need to have my mouse over the correct div before my scroll wheel will move the page, its a bit aggravating since there's no visual break between the "sidebar" and the content.

Then you haven’t been paying attention.
As someone else that's spent a large amount of time looking into this, I'd like to offer a dissenting opinion.

I agree with the analysis linking the groups.. however, the final conclusion is because the other attacks were attributed to NK, then we must also attribute these attacks to NK.

I think these assumptions need to be questioned.

The sophistication of the attacks is so out of proportion with North Koreas abilities, it almost reaches the point of absurdity.

I mean we're talking about an entire country full of people that are denied access to the internet, most do not have computers, and many don't even have the electricity to run them. We're talking about a country where refrigerators are luxury and purchased by the middle class to store books since they don't have steady electricity that would allow them to keep food cold.

When you look at the sophistication of the attacks, it's an amazing leap to assign such sophisticated cyber attacks to a country that runs it's entire computer infrastructure as an government controlled Intranet that people still access over dial-up modem.

I mean even just using Occams razor on the South Korean bank attacks...

You're going to require extremely educated people, who have the requisite hacking skill and mindsets, which often require unfettered access to information that is denied to most everyone, and small details like the fact that the attackers also are knowledgeable in multiple spoken languages and other things that are so out of the ordinary for NK.

What is more likely.. that all of these sophisticated attacks are being done by a country that can barely keep the power on, or that they are done by someone pretending to be North Korea and using them as a scapegoat?

Personally I think it's the latter.
As someone who has spent about 10 years in the software development industry, I have mostly worked with people with either less experience than me or no experience at all. I felt like I wasn't progressing much and the feeling of a stagnation in self-growth became a burden, so I sought a new job where I thought I could learn different methodologies from people who have been in the industry longer than I have.

What I have mostly learned is that everyone has different opinions as to which approaches are best and that engaging in discussions with your peers is an important part of teaching each other different aspects and perspectives of your work.

Learning programming languages and its quirks are generally things you can learn on your own, but there are a lot of little tidbits and good practices you can pick up from peer code review. As my horizon expands from working with different people on different projects, I feel more confident with my work and while coaching others afterward.
Mostly agree, but:

Can you define what you mean in particular? Because half of the nonsense in the dietary space is talk about "toxins" (and "chemicals").

Funny that you mention that, i never noticed, but firefox displays "ycombinator.com" in the URL "https://news.ycombinator.com/" in black, while other parts you are talking about are light gray. Seems more reasonable then hiding parts.
You could direct them to the download link itself.
So everyone who hosts a website has the obligation to read up on the legality of that particular website for all countries in the world, and block accordingly?

That doesn’t seem reasonable to me.

The fact it's also a completely accurate and concise summary of human political behaviour is beside the point.

Sorry i don't trust URLs from strangers, can you tell me the google search i need to do for this?
This seems fine.

I'm assuming you can always click to expand and show the full URL.

For a lot of people (devs especially) it would be nice to be able to change an option to see the whole URL at a glance, but for most people it's just a confusing mess they have to look through for the domain name.
Thank you to whomever submitted this. My main annoyance is that when I want to go to a subdomain, I'll typically start typing foo.domain.com, but now the browser sets it to www.foo.domain.com. Annoying.
>URLs are useless for normal people, normal people don't know what URLs are.

This is a truism, but I'm not certain it's true. Is there actual data to back this up? What definition of "normal" is being used here.. the average person using the internet, or non-technically trained people?

The web has been around for decades now, and everyone including my nearly 70 year old mother uses it, and URLs have been pretty ubiquitous for a long time. Not knowing what a URL is seems about as likely as not knowing what a TV channel is, or that they have a bank account number.

It seems more likely to me that normal people do know what they are, but find avoiding them to be more convenient than using them.

Check a representation of one of the stays, here:

Basically the concrete around the steel cables is nothing but a "protection box".

From the little I know about explosions, the idea is that there is a sudden expansion from the inside to the outside.
For having any damage to parts near the "core" there must be sufficient "containment", that the concrete simply cannot represent IMHO.

The actual steel used for cables is high tensile and - believe me - extremely resistant besides rather hard while concrete (particularly concrete so ammalorated to let the water creep in) has very little tensile strength.

So, IF actually there was a steam explosion, the result/effect would have been much more likely (besides "nothing") unscathed cables and ruined concrete around them (with no structural failure of the bridge)

As an alternative to explosives it is common to use expanding cement grout in actual concrete demolition, which essentially is explosive on slow motion.
When dealing with reinforced concrete you normally need to cut the rebars with a torch (or other means) after the concrete has cracked.

Check (just an example this kind of cement originated in Japan in the '70's and now there are more similar products than stars in the sky):

Same exact reason that api.domain.com or beta.domain.com matters - you're on a subdomain, not the root domain. That the internet and world at large made www the "kind of" root domain in many cases is an unfortunate thing, but I've not seen a modern server configuration that doesn't handle this case by default.
Hi, Trevor!

I get that concern. But the Agile movement didn't trademark anything and came to regret it as the word got more and more watered down. All things considered, I prefer this outcome; at least the term still has meaning. If I had to pick next time, though, it would be making the trademark but building up enough of a community to carry the flame and then handing over the trademark.
So they can be hacked in serene bliss. A stupid decision.
I stumbled upon this bug too, and here's why this is not okay to me:

For a couple of hours, I thought Citibank Singapore's website was down.

If one tries accessing citibank.com.sg, there's no redirect to the www. subdomain. (That's still the case, if anyone wants to try.)

If Chrome didn't hide the www., I would have been able to tell from Chrome's search/address bar that the various banking services that I've been accessing were all on the www. subdomain.

While that is shoddy implementation on Citibank's part, hiding the www. most definitely didn't help with the troubleshooting process.
The clearly announced intent of at least Mozilla and Google (and I'd assume Apple and Microsoft but I don't pay as much attention) is to focus on highlighting the insecure state because that has much better security UX. Labeling one site you visit today "Not Secure" stands out. With luck it might be enough that you don't type in your credit card details.

> The "brand new car" thing isn't a great example either. You can lease a new car for under $100/month which likely has lower insurance costs, is safer, and no maintenance fees other than gas (which you'll also need less of since its probably a more efficient vehicle).

Few people (like yourself) buy commodities in increments limited by their needs. Most people buy commodities limited only by their total borrowing capacity.

The unofficial Theory of Consumer Spending holds that "where credit is extended, it will inevitably be utilized." It's no coincidence retail chains push their own credit cards. Offered a $300K loan, people will buy a $300K house.

Most consumers are ignorant of terms. If the possibility exists to literally sign a dotted line and drive away in a new Range Rover, few people will opt for your plebeian Accord.

> Avoid: Plurals—use the more natural collective term where possible instead. For example "staff" instead of "employees" or "people" instead of "individuals".

What if a word doesn't have a collective term, or the term isn't very good? For example, what would you do for "computers"?

Additionally, does this mean that "employee" is better than "employees"?
