techscruggs··on Show HN: Dropflow, a CSS layout engine for node or <canvas>
This is the first site I've run in to that uses neumorphic design. Love the aesthetic -- just never seen in it the wild before.
techscruggs··on You Don't Need a Dedicated Cache Service – PostgreSQL as a Cache (2023)
This appears to be riding the [Solid Cache](https://dev.37signals.com/solid-cache/) idea that DHH has started espousing. At the core of this idea is that SSD's are sufficiently fast for caching. Sure, this may work for 37signals, but that is because they manage their own hardware. That is the exception and not the rule. And, per [this discussion two weeks ago](https://news.ycombinator.com/item?id=39443679). SSD's aren't as fast for most of us that leverage "the cloud".

Sure, you can do it, but why? I am all for removing complexities in my infrastructure. That said, Memcached and/or Redis are both rock solid and dead simple.

This just seems to be a waist of time 99.999% of use cases.

techscruggs··on First new U.S. nuclear reactor since 2016 is now in operation
This is a win for the environment and for human rights. A lot of people on here are talking about how solar and wind are better alternatives. The problem with that is that they typically need to be stored in batteries made of cobalt. The vast majority of cobalt mines exist in the Congo where modern day slavery exists to extract it. This affects everything from your Tesla to your iPhone.
techscruggs··on Has gratuity culture reached a tipping point?
Because not tipping someone that makes their living off of tips is a jerk move.
techscruggs··on Reddit sparks outrage after it demands app developer pay $20M/yr
The reason why everyone is upset is because Apollo works perfectly for the Reddit use case while the official client does not. Sure it is technically superior, but it is "better" from a product management perspective.

Reddit, Tumblr, TikTok, Instagram, etc, all attract a similar type of user but they are different products that engage people in different types of social interactions.

You can't port that.

techscruggs··on Amazon EC2 Mac Instances
At Amazon's scale, betting on M1 servers for a niche subset of their EC2 offering doesn't seem to be really risky.
techscruggs··on GoodJob – a Postgres-based ActiveJob back end for Ruby on Rails
What are some of the other exciting things happening in the Rails world these days?
techscruggs··on GoodJob – a Postgres-based ActiveJob back end for Ruby on Rails
This looks great. I'd love to remove Redis from my tech stack on applications with low throughput background jobs. Sadly, it doesn't appear to have a UI.

Resque and Sidekiq are both good enough solutions, but what makes them my defacto choice is the robust web UIs that comes with them.

techscruggs··on GoodJob – a Postgres-based ActiveJob back end for Ruby on Rails
You can implement background processing with less operational complexity. This allows you to leverage activejob to get something up and running quickly and easily.

Granted, if you start having higher throughput, you want to move on from using postgres as your message bus.

techscruggs··on Ask HN: How do you make sure your servers are up as a single founder?
1) Setup a status page for what you want to monitor (/health/queuelength) 2) Point statuscake at that url 3) Connect statuscake to pagerduty.

This approach is easy to implement and scale

techscruggs··on Ask HN: Has anyone ever been hired from “Who wants to be hired?” threads?
I hired the best Engineering leader I have ever worked with early in his career from posting on an HN "who's hiring thread".

Step1 | Head of Marketing | Austin TX | https://getstep1.com/head-of-marketing/

Step1 helps Realtor's organize the home buying process while putting their clients first. There are plenty of tools that organize this process (known as Transaction Management), but none that put their client first. As we know, the best products put their users first. We are taking that idea into the Real Estate industry.

Step1 is currently in a closed beta and we are going to need a lot of help getting the word out. Lay the foundation of a Marketing Department that you will build in your vision.

techscruggs··on Gwern's Law: Ads cost you a tenth of your users
Isn't this the inverse experiment? The theory that removing ads will increase your user base?
techscruggs··on Ahead of IPO, Airbnb achieves profitability for second year in a row
EBITDA is intended to reduce the possibility of "financial engineering".
techscruggs··on Ways people trying to do good accidentally do harm instead and how to avoid them
The medical field has a term for this: iatrogenic.
techscruggs··on List of Websites not available in the EU because of GDPR
The majority of these websites appear to be US based local news outlets. They have very little motivation to comply with GDPR.

As a side note, a lot of the comments here suggest that few people are reviewing the list at all before offering their opinion. Yes GDPR is a great step forward for data privacy, but there is little reason to shame "The Pueblo Chieftain" for not complying with GDPR. What is more likely:

1) compliance doesn't matter to them or their audience 2) they are trying to exploit and monetize your data

techscruggs··on Reddit Security Incident
Reddit can't contact them because Reddit didn't require an email address to create an account back then.

If they did require an email address, they could restore their database backups to retrieve that information.

techscruggs··on Facebook officially loses $123B in value
Stock analysts should have to share what percentage of their portfolio is in any company they write about.
techscruggs··on Ask HN: Senior developers, what would you tell a younger you?
It is a team sport. Learn to recognize when to ask for help and who is the best suited to help you.
techscruggs··on Cookies Lack Integrity: Real-World Implications
The user couldn't be signed in as the attacker if search.com required their cookie to be signed. Only search.com would have the secret key.

EDIT: Just read https://news.ycombinator.com/item?id=10279794 ... NM, you are correct.

techscruggs··on Cookies Lack Integrity: Real-World Implications
Another great argument for using signed cookies.
techscruggs··on Tech industry's persistent claim of worker shortage may be phony
That's a rather entitled viewpoint.
techscruggs··on Drat – Ruby has a double splat
What exactly would you like to see?
techscruggs··on Amazon Echo Released
I have two at my house and absolutely love them for the simplest tasks: weather, time, timer & shopping list. It's other features are fun, but I haven't found more useful than grabbing my smartphone.

For me, it's a more useful Siri.

techscruggs··on Fifty Shades of Manipulation
I disagree. The primary purpose of language is to help one give form to their thoughts. Communication is secondary to this.
techscruggs··on OpenSSL Security Advisory
Also, this is only an issue if you are running version 1.0.2. It doesn't affect any other version.
techscruggs··on OpenSSL Security Advisory
So, this exploit allows for a Denial of Service Attack. While this does mean a single person could bring down your site, it does not appear that it will allow someone to gain access to your server via this exploit.
techscruggs··on Introducing GIFV
No, probably not anyone who is reading hackernews, but imgur has a much wider audience.

GIFV will help communicate 2 things: 1) this file is audio free 2)this file is safe (people don't generally worry about getting a virus from a gif).

techscruggs··on PostgreSQL columnar store benchmarks on SSDs
Seems like you might want to consider getting all of your data in the same place. A Foreign Data Wrapper feeding a Materialized View might be a neat way to solve your problem: http://www.postgresql.org/docs/9.3/interactive/rules-materia...
