purvis··on Ask HN: YouTube down?
I had the same problem, but it was because one of my privacy extensions had disabled WebRTC.
purvis··on Leonardo Da Vinci's to Do List (Circa 1490)
I believe he wrote in mirror script, as the article mentions.
purvis··on Ask HN: When is federation a better solution than decentralization?
Correct, but you only have to trust a centralized company within your own country. You don't have to trust a bank or money transmitter in a foreign country. In the case of people in countries where they don't have an adequate level of government protection over financial transactions, I think it becomes more interesting. In cases like those, it's possible they don't even value their own local currency as a store of value and might feel a cryptocurrency has better odds of being worth more than zero by the time they need to spend it.
purvis··on Ask HN: When is federation a better solution than decentralization?
Your argument against crypto is one of the more compelling I've read. I like the "deep local optimum" visual you painted. I definitely agree if you're comparing "crypto" directly to centralized companies doing traditional things -- they're not going anywhere.

However, I think it solves a different problem. It's a geopolitical problem. Blockchain technology provide a bulletproof (so far) way of exchanging value across borders without having to trust any middlemen.

There's a quote, I believe by Erik Voorhees, saying roughly: "Bitcoin is separation of money and state".

> about my language there's more info at https::/darklang.com.

I find it slightly reassuring that someone is actually working on a language/compiler with PaaS features built in. I'd thought of doing that and jotted it down in my notebook.. assuming it was just a crazy idea.

When do you plan to release an alpha version? I'd be interested in seeing it!

purvis··on Ask HN: What are the some passive income strategies you do beside your IT job?
My farm consists mainly of rx 580 graphic cards. Due to depressed markets, my returns are just okay right now. Luckily my equipment has been paid off since December. To put things in perspective, a single 8GB rx 580 costs around $400 (if you're lucky) and only makes $0.80/day. During the peak at the end of last year, they were making well over $3/day each.
purvis··on Ask HN: What are the some passive income strategies you do beside your IT job?
I know HN is rather negative toward cryptocurrency in general, but for me it's fun. I run a small mining farm in my basement. It keeps my sysadmin skills sharp and more than pays my electric bill.

On a side note: none of this is really passive.. mining, real estate, and drop-shipping are all very active income streams. Unless you were born with a silver spoon, you probably won't find truly passive income.

purvis··on How to keep your ISP’s nose out of your browser history with encrypted DNS
If what you say is true -- on top of that, your ISP can also (in theory) fingerprint you as someone who is avoiding their DNS servers.
purvis··on Autonomous vehicles are just around the corner
> Imagine a world where police no longer pull you over for speeding, running red lights, or other traffic infractions.

In that world, I can also imagine people modding their autonomous cars in ways which would still violate traffic laws.

purvis··on The dangerous downsides of perfectionism
> It's important to remember that anxiety and panic are neurochemical responses and can have strong physical and genetic components, they don't always need to have a psychological "cause."

Agreed. Members of my mother's side are especially known to be "worriers". Sporadic levels of anxiety on my father's as well.

> I've come to recognize it as a sign of what's to come and take steps in advance to try to curb it.

Via therapy, I've discovered my own version of this, mostly around breathing. I tend to hold my breath as I start to go into my head. If I catch myself doing this, I can sometimes reduce most of the physical effects by focusing on breathing again. It's easier said than done.

purvis··on The dangerous downsides of perfectionism
Thanks for posting this! I'm always interested in other people's experience with anxiety. I'm slightly jealous yours has an origin story though. I've been anxious for as long as I remember and can't recall any traumatic experiences nor come up with any logical explanations.
purvis··on Bitcoin Bubble Makes Dot-Com Look Rational
I get what you're saying, but your math is a bit misleading. As far as I know, the missing 4m are a subset of the 16m already mined. That still leaves ~5m to be acquired in the future, albeit rather slowly.
purvis··on Urbit and the blockchain wars
Does anyone know of a good introduction to urbit? Every few months it pops up, and I can never quite wrap my head around it.

purvis··on My Sudden Synaesthesia
Does this affect how you perceive designs with colored text in them?
purvis··on Ask HN: What's your relationship with coffee?
It still does a pretty good job at preventing jitters. However, now that you say it, I think the first few times it had more pronounced effects. I'll have to try resetting my tolerance!
purvis··on Ask HN: What's your relationship with coffee?
I drink about 12oz of black combined with L-theanine every morning. Caffeine alone tends to induce anxiety.
purvis··on Spaces: Scalable Object Storage on DigitalOcean
Yep, thanks. Didn't change it to TB on the calculator.
purvis··on Spaces: Scalable Object Storage on DigitalOcean
Do you have something else in your estimate? It shows as $5.63 for me.
purvis··on Azure Container Instances
Your story sounds so familiar, someone could read what you wrote above and think it's me.. though I like to think of myself as a generalist rather than "fullstack". I tend to believe "fullstack" is a marketing term for acquiring slave labor. You're right though, it's required at this point for smaller startups.

> I wonder if I could ever possibly get into that fight

I wonder this too. I've been using AWS for 4+ years at my day job(s). The main pain point for almost all users, including myself is the cost. I think a product/tool that helps companies save on cloud costs would be invaluable. The difficulty is convincing crusty old ops people that the product is something worth trying.

Anyway, after my current employer runs out of money, I'm going to do a startup of some sort. While one of my many idea was like the one we outlined above, I'm actually starting to shy away from the infra/op verticals lately.

My email's in my profile, if you ever want to bounce ideas.

purvis··on Show HN: Chromeless – Headless Chrome Automation on AWS Lambda
It's parallel because AWS Lambda is inherently parallel? Or are you referring to within JavaScript?
purvis··on Azure Container Instances
> Terraform is basically this tool, but I want an even easier interface, terraform still feels somewhat too specific to me -- I don't want to even have to write config or specify some "aws" adapter that will make my config work on some provider. I want instant, multi-cloud (possibly) heroku, using only the network, hard-drive-space, ram, and lxc "primitives".

This sounds very similar to some ideas I've been stewing on over the past few months. One of them being a multi-cloud terraform-like tool which abstracts away the low level details of which provider an instance is provisioned onto (whichever is currently cheapest). It could also automatically determine how firewall/security groups/networking should be configured.

If you happen to create two instances in two different providers that need to communicate privately over say port 443, the security groups would be updated automatically to account for this, bridging the two providers.

One major thing to consider in doing this is the bandwidth. If you look at the fine print in these providers, the outgoing bandwidth is where they really get you. So if your backup server is in a different provider than your database, you might see some hefty data transfer fees while performing a daily backup.

Just curious, what's your background? Are you an infrastructure type, or are you a general developer who just wants a tool like you've described? Sometimes I can't tell if this is something people really want or if I've just drank too much of the infrastructure automation koolaid.

purvis··on On Password Managers
I've recently installed Enpass and I'm currently in the process of evaluating it. I really like the idea so far. My main concern is that they're not charging enough and wonder if the business model is sustainable.
purvis··on Ask HN: How do you manage your daily non-work related tasks?
I've been doing something similar to your everydaycheck app, but manually using google sheets for about a year now. Works great for me too. Your app looks pretty neat!

Does it get much interest from others, or are you the main user?

purvis··on Show HN: Quilt – manage data like code
The main thing is how you are able to offer unlimited disk, when anyone can start uploading data? Some users might upload very large amounts of innocent data, others might simply abuse it as a sort of data backup system. More nefarious users might even try to distribute malware.
purvis··on Show HN: Quilt – manage data like code
Do you plan to curate the free plans? If not, how will you prevent abuse? (thinking in terms of both the service and its users)
purvis··on Should I invest in startup or in crypto currencies?
How do you keep track? Individual wallets or do you keep them on exchanges?
purvis··on SecureLogin Authentication Protocol 1.0
My initial concern was an aggressive server timeout on nginx/haproxy. I think the defaults should be long enough, but it's entirely possible to have something lower than 20 seconds. (and the app developer might not even be aware of this)

I have no reason to think it's unacceptable, was just curious. Interesting project!

purvis··on SecureLogin Authentication Protocol 1.0
I'm not too familiar with ruby/rails, but does this mean the HTTP request just sits open for up to 20 seconds? Is this common/acceptable practice?

    # user is given 20 seconds to approve the request
    20.times{
      sleep 1
      sltoken = REDIS.get("sl:#{state}")
      break if sltoken
    }
