windlep··on Vocore2, a ridiculously small Linux PC
The Neutis is $49, the VoCore2 is $18. They seem to have different power consumption as well. While it might be similar in size, the cost difference is substantial. The best choice as usual depends on the project.
windlep··on Star Citizen's ARK Starmap
Lovely site, I'm guessing this is still an early draft so there hasn't been much optimization. I'm on gigabit fiber and it took awhile to load.

FF Network panel shows:

- 131 requests

- 32.74 MB

Many of the graphics requests could likely be wrapped up, sprites, etc. Looking forward to a more optimized version.

windlep··on How Firefox is using Pocket to try to build a better news feed than Facebook
You can disable Pocket. Once disabled, there is no change in the browsing experience.

> The true history of Pocket suggests otherwise -- in 2015 Mozilla integrated Pocket, which was at that time a private company separate from Mozilla, into Firefox.

What in this true history you cite indicates otherwise?

Please elaborate on how some config settings are altering your browser experience.

windlep··on How Firefox is using Pocket to try to build a better news feed than Facebook
Hover over pocket area on new tab, click the '...' in the top right, click "Remove Section", done.

Firefox is about letting you control your browser experience, that's why the ability to easily remove options you might not like will always exist. If/when this ever changes, that would be a significant departure from their Mission statement.

windlep··on Ask HN: Work from home (WFH) setup
What model of TV is that? I've been looking at going to a larger 4k screen for a similar reason, but am wary of the increased input lag all TV's seem to have (the dreaded molasses feel of the cursor).

Would love to find a screen around 43" or so without the lag.

windlep··on The Boring Company raises $112M from Musk, early employees
> Labor: they want to increase automation so there are fewer workers needed, and tunnel faster so they can pay for fewer hours of work.

Musk has not had a great track record of reducing costs by increasing automation.

windlep··on Supersonic Flight Prepares for Takeoff Again
And if it had conference rooms, high-speed internet, a fitness room, and the slower trip helped minimize jet lag... I'd be quite happy with that as well.
windlep··on How the Irish Teach Us to Die
The stats here seem to indicate Ireland is immediately behind the US in cancer rates: https://www.wcrf.org/int/cancer-facts-figures/data-cancer-fr...
windlep··on Brooklyn Bitcoin Mine Causes Static for T-Mobile Users
It says the person shut it off and claimed it was an Antminer s5, not that the FCC verified what was causing the interference. Was there some additional 3rd party confirmation of what it actually was?
windlep··on Google doesn’t necessarily need innovation
I doubt its healthy for people to sit around all day while everything is delivered to them so they never have to go anywhere nor interact with anyone else socially in public.
windlep··on Firefox bullshit removal
The person that pays my paycheck tells me what to do. The only thing Mozilla was told to do in the contract with Google is to have them as the default search engine.

Besides for the search engine requirement per contract, how is Mozilla's product beholden to Google?

I'm somewhat surprised that was downvoted, as I thought people knew how these contracts were arranged and what they included. They're about the default search engine placement, that's it. Google obviously doesn't get to provide input/requirements into Mozilla product design, marketing, etc.

windlep··on Firefox bullshit removal
Ok, so that makes Mozilla beholden to them how exactly? Is Google calling up Mozilla asking them to do them favors in the product? Are Mozilla engineers being asked to write in special features that Google asks for?

Yes, Google provides 90% of the revenue or somewhere around there. But I still haven't heard how exactly Mozilla is doing special favors to Google or is in some way beholden to it.

Mozilla has a contract with Google to be the default search provider for a set period of years. I have never heard of anything else being in there that allows Google to make any product requests on Mozilla.

How come no one wants to say how exactly Mozilla is doing what Google wants?

windlep··on Firefox bullshit removal
I was under the impression the search deals are merely which engine are the default. How does having the default search be Google make the Mozilla corp beholden to Google?
windlep··on The Most Expensive Mile of Subway Track
Not only that does it occur, but it also occurs that the same people messing it up have bought off both sides. So it's not like voting for Dems or Republicans will magically make it cheaper. They'll just change who pays the insane prices, if that.
windlep··on Mozilla’s revenue increased significantly in 2016
Mozilla has around 1050 employee's give or take a dozen (at the Mozilla Corp at least, Mozilla Foundation has a few as well, but is accounted for separately afaik).

Some top executives and board members are paid 1-3M according to documentation out there, sure. If you compare to other companies where they'd be in charge of as many people at a similar level, this is substantially under what they could demand.

As an employee, they pay us well with great benefits, though I could likely make 2-3x as much at another company (just like the execs). I rather like Mozilla's mission and my work though, and the work-life balance is nice.

windlep··on Apple has proven me wrong about HomeKit
I was originally considering openhab, but then I discovered Home-Assistant (https://home-assistant.io/) and I've been hooked since. It ticks off a bunch of check-boxes that made it a great home OSS solution:

Pro's

- No internet required, can run entirely on a Rasberry Pi

- Integrates with most everything thanks to the huge component library (https://home-assistant.io/components/)

- Easy to write your own Python component to integrate with new stuff

- Can use existing SmartThings/etc hubs or Z-wave usb stick to talk to most anything

- Fairly easy to write automations

- Well written Python 3 code-base that's fairly easy to read and see what's going on yourself

Con's

- Definitely more for the DIY tinkerer

- Need to write YAML for the automations, though a new GUI makes this easier for many cases

Setting up an SMS to me when a motion sensor tripped was pretty easy, my automation was:

    - alias: Alerting on bedroom motion
           initial_state: False
           trigger:
             platform: numeric_state
             entity_id: sensor.bedroom_burglar
             above: 0
           action:
             - service: notify.aws_sns
               data: 
                 message: "Bedroom alarm sensor has been tripped!"
                 target: HassAlert

I've had it running for over a year now, and it's been quite nice.
windlep··on Out of all major energy sources, nuclear is the safest
Indeed, it also fails to mention hydroelectric. Nor is there any mention of how much it costs per TW/h, especially when you factor in the insane cost from just a single accident or the fact that the waste has to be safely and securely stored for a very long time.
windlep··on Meet the Man Traveling the World on $25M of Bitcoin Profits
It's worse than just liquidity, if he can unlock his wallet on his phone to verify it and its balance on the spot.... not only is it liquid but he's effectively carrying it on himself in cash at all times.

At least it's only $2.5 million or so remaining, since the rest is now likely in assets that require more effort than merely access to this person+phone (and attempts to rob a person of assets in a bank are usually more traceable than stealing bitcoin). Still seems a bit crazy though.

windlep··on There are very few suitable use cases for DynamoDB
Sorry about that, I had difficulty finding anything about the consistency model of BigTable. Upon further reading on SSTables and how BigTable distributes them across nodes, it appears there is full consistency but if a node goes down the data on it is inaccessible?
windlep··on There are very few suitable use cases for DynamoDB
Agreed entirely, I do wonder what kind of internal constraints led Amazon to have these limits. Maybe in the future they'll go away, as so many other seemingly arbitrary limits do.
windlep··on There are very few suitable use cases for DynamoDB
I said it was per node (which is a shard), it's not a limit per table. Did you read the original article or my reply? Both of them state this is per node and how DynamoDB decides when to shard to more nodes.

Edit: Sorry, I did mention 10GB originally in relation to a table. That was incorrect of course.

windlep··on There are very few suitable use cases for DynamoDB
I don't know what the article author is storing, but it's noted that 10GB of data is stored per node. That's quite a bit of data for a single table, and the 10GB is per shard of a table, not per 'database' (DynamoDB only has a notion of tables).

Amazon has deep dive talks on DynamoDB on YouTube[1] that go into lots of these details and how to avoid problems from them. It's not that different from understanding how to structure data for Cassandra, Mongo, etc. All the NoSQL systems require an understanding of how they work both to structure your data and ensure optimal performance.

For example, maybe one's consistency constraints are better met by DynamoDB instead of BigTable's varying consistency on different query types[2] (the author of this article didn't address consistency at all). With DynamoDB, you can get strongly consistent reads and queries all the time [3].

Overall, it seems like a kind of weak reason to make the strong statement about "probably shouldn't be using DynamoDB". Maybe a better title would be "Understanding drawbacks of large datasets in DynamoDB". I do hope the author understands the consistency changes they may experience in BigTable, as it could easily require large changes to the code-base if strong consistency was assumed on all queries.

Edit: Fixed inconsistency in what the 10GB limit was referring to, not per table, but per node (shard) of the table.

windlep··on Eye-witness stories from Chernobyl
What's even creepier is that the main reason Kodak was notified is because they were able to determine when the testing was occurring based on their manufacturing defects (and it meant they lost a lot of product to sell). They sued to stop the US Govt but got an agreement to know the testing schedule so they wouldn't produce film on those days.

The article mentioning this was on HN awhile back,

windlep··on ActivityPub: a federated social web standard
Small section about how Spam should be handled somehow by a server. Sigh. How about we build a federated spam/harassment prevention system first?

I have little hope that a spec not designed to reduce/stop harassment up front can have it bolted on later successfully.

windlep··on The Boring Company FAQ
Indeed, strange how that's not mentioned at all. Or whether any transportation engineers have evaluated what kind of traffic reduction would occur from using all these tunnels for a subway system instead of just moving a few cars around.

Edit: The more I think about it, the worse it seems. Compare how much space is eaten out of the road above for a few cars... per minute?...to go up/down to this tunnel vs. how many a stairwell could take up/down to the subway. Even if the car's were relatively crammed close together in the tunnel, I can't imagine it would be anywhere near the density you could fit on subway trains. The economics of this make no sense.... unless you consider that this will be something that only the incredibly elite will be able to afford. The majority of people in rush hour LA traffic will remain stuck there, the rich will go down I guess.

windlep··on US Government Fears Another Explosion Of The Ransomware Plague It Helped Create
Liability.

If the NSA was actually forced to be liable for the damage of their hoarded 0-day's should they leak, that might have a bigger effect than any 'guidance' I would imagine politicians might pass in a law. I hate to suggest something that involves yet more lawyers, but its amazing how effective that can be to make people in charge do some serious risk-assessment analysis about what they hoard and for how long.

windlep··on Human behavioral complexity peaks at age 25: study
I wonder how/if this relates to the fact that many mental illnesses fully manifest around 25 as well.

"Roughly half of all lifetime mental disorders in most studies start by the mid‐teens and three‐fourths by the mid‐20s." - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1925038/

windlep··on Chrome will aggressively throttle background tabs
The amount of people that will understand what that means is not very substantial. Usually asking for more permissions confuses users as well, people get permission fatigue.
windlep··on Why Many Cities Have No Money
I've seen the infrastructure thing come up for awhile now, and it's definitely true. In my area, as in others I've read of, they're smashing paved roads into gravel roads as the paved are too expensive.

The thing that fascinates me is that it feels like a forgone conclusion that infrastructure costs cannot be made cheaper. Have we really hit the most cost effective, cheapest, most sustainable method of laying/replacing sewer/gas/water lines and roads?

There's no innovation left at all when it comes to making pipes that are more easily replaceable without digging the entire road up? There's no brilliant ideas left at all on how to 'pave' roads so they're smooth enough in a way that costs less money, or lasts way longer? Heck, while we're talking improvements maybe we should have a way to pave a road such that we don't have such massive runoff and its more resilient to minor settling underneath without opening large potholes.

I do wonder whether the shit really hitting the fan, and massive chunks of the population having their roads smashed back to gravel might shake a few new ideas out.

windlep··on One More Sign World Is Shrinking – eBay Is for Suckers
How would you prove you were opening the box as shipped?

If investigative news meant anything, they'd be all over this. But most investigative news is gone, and there's so few investigative reporters and trustworthy news outlets left that its hard to hold ebay's feet to the fire.
