AgentK20··on Missing the Point of VR
I think one thing that's being skirted past by the author with regards to allowing freecam movement is that freecam is the #1 way to cause motion sickness in VR. The purpose of the realism isn't _just_ to keep the user engaged/sell units/have a good experience, it's also because alignment between "what you see" and "what you're doing" is a critical part of the inner-ear feedback loop. There's a reason that so much effort goes into comfort reticles, motor controls, etc: That if you do it wrong your users puke.
AgentK20··on Regarding the eSIM-only iPhone 14 models in the U.S.
Personally I feel that this is a step in the right direction, albeit at the cost of some user pain in the short term. Prepaid SIMs are already manufactured, packaged, and shipped to convenience stores, so why not a Prepaid eSIM QR code? I imagine that it'd be cheaper to print a simple QR code for an entire factory run than to have SIM cards manufactured with unique data on them, and the savings can be spent upgrading the infrastructure to support eSIM (a one-time process).
AgentK20··on Cost of ultra-rapid EV charging increases by almost 50%
Of course it is. EV charging doesn’t exist in a vacuum, nor do gasoline prices. In most situations the electricity is still derived from fossil fuels of some form, with peak power coming from natural gas plants. Until the grid itself is primarily powered by renewables, we won’t see divergence between fossil fuel prices and electrical prices.
AgentK20··on Why META's career page is broken?
Try using Chrome. I had numerous issues with it in Firefox that don’t appear in Chrome.
AgentK20··on Verizon customers might want to check their privacy settings ASAP
Is this only for Verizon Mobile customers, or are Verizon FiOS customers affected as well?
AgentK20··on MangoDB: An open-source MongoDB alternative
Another important resource for developers looking for alternatives to MongoDB itself is Percona Server for MongoDB (https://www.percona.com/software/mongodb/percona-server-for-...), which is based on the MongoDB community edition (and is therefore still bound to the licensing issues with it) but adds almost all of the features found in MongoDB Enterprise for free, with costs paid by support licensing similar to Percona's other offerings.

AgentK20··on Buried in the 2700 page infrastructure bill
I'm sure this will be replacing the gas tax, not in addition to it. /s

In actuality I do believe there should be a "fair" way for EVs (which I think this tax is probably targeting, as they currently do not pay gas taxes which are supposed to aid in roadway repair) to pay "their share" of roadway maintenance burden. Gas sales tax happened to work out quite neatly because it was a) proportional to the amount of use of the vehicle(s) and b) encouraged further and further efficient vehicle use, but there's no 1:1 parity for EVs.

Personally I wouldn't object to some level of vendor integration where the car itself reported its mileage on a yearly basis for tax purposes and then was billed as part of your yearly registration fee.

AgentK20··on Google Cloud reported an operating loss of $5.6B in 2020
HOW?

Google Cloud Platform has MASSIVE markups compared to equivalent service providers, either from "the big three" or smaller service operators. These smaller service operators have far less margin to work with, yet manage to not only break even but to turn a profit! Either GCP has some product that is a metaphorical black hole consuming all of their excess revenue, or Google generally is spending far too much money doing the same thing that everyone else is doing.

One of the things I've noticed GCP prides themselves on is uptime, and I'm wondering whether they're doing something like _doubling_ their costs to have seven nines of uptime for the entire platform, which practically doesn't matter for anyone other than a handful of clients (healthcare, government, military, etc)

AgentK20··on Tesla silently charges $14k when activating Autopilot on non-enabled vehicle
Would love to see if this is actually a thing (already have purchased the package for my M3, otherwise I'd go test it myself). If so, it should be changed, but I can't imagine this is actually how it works as we would have heard of numerous incidents of this occurring accidentally (unless this is a recent change on Tesla's part).
AgentK20··on IPv4 pricing
Per ARIN (and pretty much all regional RIR) rules you're not allowed to purchase IPV4 space without proving the need for it, with a moderately thorough review process (https://www.arin.net/participate/policy/nrpm//#8-5-specified...)

Any other purchase reason is likely to result in ARIN pulling your "ownership" entirely when they discover it.

From what I understand most of what's being sold off right now on ipv4 auctions are from companies who had too much IPV4 that they no longer need, or companies that were liquidated.

AgentK20··on AWS's Egregious Egress
Not when we don't control the game client. We're the largest Minecraft server in the world (220k peak concurrent users) yet we operate entirely as a third party with no involvement from Microsoft.
AgentK20··on AWS's Egregious Egress
I would say the exact opposite in some ways for teams who are not using AWS yet. My team for example has been operating bare metal for 8 years now, and we know how to do that. Transitioning our team to the "bespoke way" that AWS does things has a huge opportunity cost, too.
AgentK20··on AWS's Egregious Egress
Working in realtime games that require high bandwidth usage, AWS and basically every other public cloud is fundamentally unusable for us because of this exact problem. Our bare metal infrastructure for the Hypixel Minecraft network uses 3-4PB per month, so we simply lease a 100gbps transit link billed at 95th percentile.

Last I checked, AWS wanted ~$200k per MONTH, for just bandwidth (no compute, memory, storage, or anything else). We'd love to be able to use the cloud, but not at the cost of increasing our monthly expenses by an entire order of magnitude, so we just stick to bare metal colocation.

I honestly believe that if you have the technical skill in-house, and are spending more than, say, $30k/mo on public cloud hosting, that you should seriously evaluate whether bare metal could significantly decrease your costs.

AgentK20··on MongoDB Wire Protocol Specification License
We had a pretty bad experience with our company as well, being bounced along nearly half a dozen sales reps (each of whom insisted on having a meeting) before actually managing to get a quote, which was ludicrously high for the one or two features we wanted. For anyone who IS looking for MongoDB enterprise, just use PSMDB (https://www.percona.com/software/mongodb/percona-server-for-...) instead. OSS version of all the enterprise features of MongoDB.
AgentK20··on Virgin Galactic Unity 22 Spaceflight Livestream [video]
Stream "live" for 10 minutes now with just a static image. Definitely should take some things from SpaceX's book, re: making a dynamic "We'll be live soon" screen.

Edit: Youtube stream is properly live now. 12 minutes of "dead air".

Should be tagged with (2020). Also, that particular quote I can't seem to find in the linked article. It's an interesting interaction nonetheless, but the title should not misquote (unless I'm just not seeing a folded down section of comments).
AgentK20··on 1 in 5 EV owners in California switched back to gas because charging is a hassle
Honestly this sounds more like what I'd regularly expect for _any_ new purchase of high value. Many people rush into buying "the hottest thing" without doing their proper research ahead of time, determining what the impact on their life will be, etc. This says less to me about EV charging being a "hassle" and more about humans being resistant to change, not to mention the lack of general public acceptance (landlords) of charging infrastructure.
AgentK20··on Auth0 Down
This type of incident is exactly why I dislike identity federation as a service. Yes it's difficult to get right, and you open yourself up to additional risk and technical complexity to do the federation yourself, but simultaneously how many businesses are currently completely down and just sitting on their hands waiting for Auth0's engineers to fix their systems?
AgentK20··on International Backup Awareness Day (2009)
Should have the year in the title, post was from 2009. Still relevant and a good read, though, and a reminder to CHECK YOUR BACKUPS.
AgentK20··on The spot price for electricity in Texas is currently about $9000 per MW-hr
While I can definitely agree that there's shortcomings in putting all your eggs in one basket, this seems to be more of a problem of the lack of interconnectivity between the Texas grid and the rest of the US. They chose to keep a totally segmented system, and now as a result of that are unable to effectively import power from areas where it is more readily available.

AgentK20··on Google outage – resolved
And somehow Pokemon Go is down, too. They use GCP for hosting, but I'm not seeing other outages on GCP. Maybe they have deeper integration with Google's Cloud than publicly disclosed?
AgentK20··on Creative Director of Stadia suggests streamers should pay license fees for games
Can't update the link anymore, but a better link might've actually been https://twitter.com/BangBangClick/status/1319305553454288896 since that was the root of the conversation
AgentK20··on Cloudflare Radar
I would say likely due to the uneven population distribution around the world, combined with day-of-week trends due to people being off work/school.

The more interesting datapoint to me is the hour-by-hour breakdowns of HTTP vs HTTPS, likely due to particular countries that discourage (and have ISPs that block) encrypted traffic.
