ropiku··on American Airlines agrees to purchase Boom Supersonic Overture aircraft
Due to noise constraints supersonic flight is banned over land right now. If they lower noise pollution maybe laws will be changed.
ropiku··on Coinbase to go public on 4/14
GBTC has no redemption mechanism, you can wrap more BTC into GBTC but not the other way around. For ETFs this is what solves the arb. You can do your arb but you still need to offload GBTC at some point and the only option is to another buyer of GBTC.
ropiku··on Google Cloud SQL now supports PostgreSQL 13
There's a big difference between AWS Aurora and AWS RDS PG. Both are managed services.

Amazon supports PG 12 and 13 is in beta. Aurora is Amazon's fork of Postgres which has different storage and replication so will always be behind.

Huawei 5G CPE Pro (if you don't mind Huawei) has good reviews, has ethernet and you can use external 5G antennas.

On the way back unfortunately you have to stop in Brussels because Amsterdam/Rotterdam do not have passport control for departure.

ropiku··on Ask HN: What cities have gigabit fiber internet access?
Happy with 1G Hyperoptic too. There's IPV6 or £5/month if you want your own IPv4 otherwise it's CGNAT.
ropiku··on A 100k Botnet Turns Home Routers to Email Spammers
I have no problems with a gigabit symmetrical line on ERLite-3. UniFi Security Gateway is the same hardware but in a nicer interface that works with UniFi APs & Switches if you want to go that route but you have to also host a controller. You can also upgrade to a ER-4 for a much faster CPU but I don't think you need to.

ropiku··on Ask HN: Who is hiring? (March 2018)
We're open to people outside the US (and we have a few) but as mentioned we're looking for people with a high overlap with PST for easier collaboration.
ropiku··on Ask HN: Who is hiring? (March 2018)
We're open for remote engineers/data scientists, not quite all the positions unfortunately.

Envoy | All types of software engineering jobs | San Francisco, CA and distributed | Full-time | https://envoy.com

We're on a mission to create the office of the future and visitor management is just the beginning. We already launched our second product (Deliveries).

We’re building a world where you know instantly when packages are delivered; where your office unlocks securely and automatically when you arrive; where you can book a meeting room simply by walking through the door.

We have 1/3rd of our team working full-time remotely but continental US time zones are preferred so we can easily collaborate.

Our stack is built on Ruby&Rails, PostgreSQL, Redis, Elixir, JavaScript (Ember, React Native), and a few more things. We’re currently hosted on Heroku with some AWS (mostly Lambda) though we are constantly reevaluating as we scale.

We value being a top-notch organization with a strong engineering-driven culture, and have the same high standards with our code, systems, and people. We value learning and growth (and not being bored) and hire diverse, well-rounded, communicative people we can envision being friends with and trusting.

You can get more info on our jobs page https://envoy.com/jobs/ Or just apply to https://goo.gl/GEy3JE and we’ll make sure to get back to you.

ropiku··on TomTom ditches map updates for some sat-navs
You are technically true but if you don't have internet connection to get the almanac (future position of satellites) you have to wait 12.5 minutes to download it very slowly from the GPS itself. That's what parent was saying. It works but the time-to-fix is very high.
ropiku··on Three months of content moderation for Facebook in Berlin
> And it's not like Facebook (or Twitter) couldn't get the money

What makes you say that ? Facebook barely makes $5/quarter (3 months) in revenue. They couldn't even afford $1/month/user. Meanwhile Twitter has never turned a profit ever.

ropiku··on Building a Lightroom PC
Try Capture One since they have specific support for X-Trans since version 10. Or if you want to continue Lightroom you can bulk transfer the raw files with Irident X-Transformer then import them in Lightroom. Only worth it if you really want the best quality.
ropiku··on A Message to Our Customers about iPhone Batteries and Performance
It's not just battery life, some people might live with 50% battery but due to chemistry they can't put out the designed voltage leading to the iPhone suddenly turning off.
ropiku··on $17B Modernization Plan for Puerto Rico's Grid
It is a good investment until due to mismanagement they don't make enough revenue to pay up. PREPA is already in default on their bonds so I don't see how they can convince anyone to lend them even more money. The previous bondholders probably have dibs on the income stream already.
ropiku··on Net Neutrality’s Holes in Europe May Offer Peek at Future in U.S
How is it unfair ? They are in a totally different business.

ISPs are providing a service to their users: the internet. Their users pay for internet access (not just a certain subset) and they decide that they want to use the bandwidth for Youtube or Facebook. 5mbps on a "cable in the snow" is 5mbps regardless if it's coming from Youtube or Netflix or some indie company.

ropiku··on Automated package management using Google Vision OCR
Happy to answer any questions about our new product! We're very excited about the combination of OCR and ML to solve everyday problems.
ropiku··on Delta Lyft – Link Skymiles and Lyft
There's an Uber + SPG (Starwood) program but you need one stay with SPG. Those points can be then transferred to airline miles.

ropiku··on Verizon Throttles Netflix Subscribers in Test It Doesn't Inform Customers About
But if you're in a longer term contract you're out of luck for a while. If they are allowed to change the service then they must allow customers to switch providers without exit fee.
ropiku··on Twist – Mindful Team Communication
Looked at the Twist mac app and looks all native, using Swift. Unlike Slack which is an Electron webapp.
ropiku··on The EU’s new roaming rules
Yep, iOS 10 added it.
ropiku··on Google’s modular apartment plan hailed as possible housing crisis fix
What tax loopholes are used to avoid local taxes ? From my understanding corporate tax doesn't go to the local government. Looking at City of MV page they only tax Business license, property and sales tax. From what I know they prefer offices due to prop 13 which limits property tax growth.
ropiku··on Microsoft will make the most from WannaCry
Afaik AV wouldn't even protect against WannaCry until after its signature was already in the wild, when it was too late. But Windows update would've prevented the SMB hole by which it spread in networks.
ropiku··on Why Doesn’t the Surface Laptop Have a USB-C Charger?
I'm thinking the cost for not including Thunderbolt 3 (needs a chip, more power, etc.) but not for missing USB-C.
ropiku··on Why Doesn’t the Surface Laptop Have a USB-C Charger?
You can get the same from other kinds of USB-C docks, not just proprietary Microsoft. Griffin makes magnetic USB-C cable if that's what you are looking for and possibly other producers will start.
ropiku··on Symantec CA Response to Google Proposal and Community Feedback
There is a risk but they would already lose all Android users. If Apple and Mozilla then join in they pretty much would lose all iOS and macOS users.

For a bank maybe a user would temporarily accommodate but it would affect online stores and SaaS business a lot.
