drone··on The Magician of Meat: How Pat LaFrieda Reinvented the Burger
We dry-age our own beef at home (usually buying a whole prime ribeye for the purpose).

We found that the bulk of the flavor change happens in the fat, and that we have a LOT of fat trim left over after cutting down from the whole to steaks (usually about 5+lbs of fat after trimming down and cutting steaks). So, what we do is save all of the trimmed fat, then grind it with cheaper/leaner meat (game, etc.) to make amazing burgers and sausages.

I haven't found that the flavor of a 100% dry-aged beef burger vs. one w/ up to 20% dry-aged fat is night-and-day different. Not to mention, this lets us use pretty much everything -- the bones make stock, so we have at best about 1/2lb of real "waste" after DA'ing a ribeye, which is mostly the crusty outer edge.

We did a taste test w/ fresh brisket trimmed to 10%, then added 15% DA fat vs. 30-day DA brisket burgers (trimmed to 25%), and only about half the people who tried it could tell a difference.

drone··on US Supreme Court strikes down federal law prohibiting sports gambling
Looks down into the syllabus, I think you'll find 2.(a), 2.(b), and 2.(c) have the key components from their regard:

1) “Congress may not simply ‘commandeer the legislative process of the States by directly compelling them to enact and enforce a federal regulatory program.’”

and

2) "The distinction between compelling a State to enact legislation and prohibiting a State from enacting new laws is an empty one. The basic principle—that Congress cannot issue direct orders to state legislature—applies in either event."

3) "... since the Constitution “confers upon Congress the power to regulate individuals, not States,” ... "There is no way that the PASPA anti-authorization provision can be understood as a regulation of private actors. It does not confer any federal rights on private actors interested in conducting sports gambling operations or impose any federal restrictions on private actors."

drone··on US Supreme Court strikes down federal law prohibiting sports gambling
It's right there in the beginning of the opinion:

The Professional and Amateur Sports Protection Act (PASPA) makes it unlawful for a State or its subdivisions “to sponsor, operate, advertise, promote, license, or authorize by law or compact . . . a lottery, sweepstakes, or other betting, gambling, or wagering scheme based . . . on” competitive sporting events, 28 U. S. C. §3702(1), and for “a person to sponsor, operate, advertise, or promote” those same gambling schemes if done “pursuant to the law or compact of a governmental entity,” §3702(2). But PASPA does not make sports gambling itself a federal crime. Instead, it allows the Attorney General, as well as professional and amateur sports organizations, to bring civil actions to enjoin violations.

That is, rather than say sports gambling shall be declared illegal, they made it a civil offense for a state to pass a law legalizing sports gambling.

drone··on A Floating Mass of Fire Ants in Texas
To be fair, as someone who walked into one of these masses during the Baytown flood of the 90's (back when the San Jacinto caught on fire, that one), I'll take screaming cows, snakes, and rabid raccoons over floating masses of fire ants. All the former can be shot or kept away with a stick, not to mention seen from a distance. Those ant rafts can sneak around between other floating detritus and catch you by surprise, and there is no defense once they catch you.

Fire ants are an invasive species which have wrecked havoc on the local ecology and cause serious human harm.
drone··on Why green olives come in jars, but black ones come in cans
No worries =)

Castelvetrano is one of those interesting olives for me, personally, in that I'm not a big fan since I prefer the richer, earthier flavor of the slow-cured (dry-cured are my favorite!) olives, but my wife loves them most of all b/c she doesn't like the earthier olive flavor.

So, it's one part plant, one part process that gives them their unique flavor. The olive its self has a bright, crisp flavor with a good buttery profile. The process used for these is an extreme example of the lye-cured process, where they are lye-cured for just a few hours, and then soaked in fresh, cold water for at most a couple of days (changing the water every few hours). Basically, one of the most minimal processing of the olive world. After this, they are generally kept in a lower-salinity brine than other olives, to avoid the "salty bite" of a standard olive.

So, the Castelvetrano olives are really an exemplar of how lye can be used to great advantage in curing olives, to create a unique flavor profile.

drone··on Why green olives come in jars, but black ones come in cans
I realized I left a few questions unanswered here, and for completeness' sake:

* Green olives can also be fermented (i.e. w/ yeast and bacteria, instead of using a lye- or pure-water 'cure'), to remove the bitter compound, and would thus be "pickled" in the traditional sense. These olives are not as green or firm as lye-cured olives.

* Why not pasteurize green olives, if you can do it with black olives? You can, but the heat would cause the green olives to become mushier, people expect green olives to be firm, and ripe (black olives) to be a bit soft. Soft green olives often are less desirable, outside of some specific preparations. (I.e. 'Greek-style' "crushed" olives.)

* Can you ferment, and thus pickle, black olives? Sure, why the heck not? Many Greek styles of black olives are done this way.

* Yes, you can pack cured green olives in oil too, like black olives. Anything to reduce the bacterial and oxygen activity in the olives will help to preserve them.

drone··on Why green olives come in jars, but black ones come in cans
"Pickling" may be an incorrect term here.

Green olives are unripe olives, black olives are ripe olives. Unripe olives contain very high levels of oleuropein, which is especially bitter and thus green olives cannot readily be eaten. Ripe olives have little, if any, of this compound.

To make green olives edible, they have to be cured (typically using a lye-based process for speed, but can be done with plain water over a longer period of time) to remove the oleuropein, and thus making them edible. After curing, they are typically kept in a salty brine to extend their shelf life.

Black olives do not need the curing process, but can be brined in either a salty water brine, or oil, or no brine at all via pasteurization.

drone··on Pcb-stackup: Generate beautiful and accurate SVG renders of printed circuit boards
You're right, sort of! =)

We use gerber-to-svg (it is the best we've ever worked with) server-side, but we use svg-stacker to generate images for the cases where we need them (thumbnails, printouts, etc.)

On the front-end, we use html5 canvas rather than a pre-stacked SVG.

drone··on Show HN: Kitnic – A new way to share your electronics projects
Sorry about that 404, we did a bit of content re-architecturing last week and it looks like that file got missed, should be fixed now.

Our XYRS (X-postion, Y-position, Rotation, and S[ide|ize]) is combined placement and bill of materials format. For several EDA tools, we extract that automatically (Eagle, KiCad, Diptrace, and anything ODB++), but it provides a complete set of details for us to do the assembly.

For helper visuals on DIY builds, have you seen Copper App? They have one of the best DIY-walkthrough for building that I've seen, on-par with what we've built for our assembly techs, but very clean and polished for casual users.

As you finish building out the platform and start thinking about whether or not you want to provide some direct ordering connections, please keep us in mind. Also, if I can help with structuring data for our service in any way, please don't hesitate to ask!

drone··on Show HN: Kitnic – A new way to share your electronics projects
Hi Kasbah, I'm Chris from MacroFab.

We actually have a lot of people asking us to provide this kind of functionality for open-source projects. In a lot of cases, the projects have complex assembly requirements (like BGAs) that restrict self-assembly to the most capable makers. By making it really easy and affordable for people to order a single unit, they see it as an excellent way to spread their project to the world.

Our model is designed to support the business-side of electronics manufacturing and operations, and our intention is to be impartial to which marketplaces/how makers sell their products. Instead, focusing on enabling connections to those market places. This is why we have not chosen to create this sort of marketplace for our customers directly. (We are integrating with a lot of other popular platforms for makers/inventors that want to sell their designs later this year.)

I'd love to help you create this sort of integration, or to answer any questions you have - please feel free to reach out to me here, or at church at macrofab net. Our API documentation is also available here: https://factory.macrofab.com/apidoc/v2/

drone··on Startups Can’t Manufacture Like Apple Does (2014)
There's nothing wrong with CNC for that type of product, and it is necessary as well. Many of the higher-end products in that market use nearly 100% CNC, whereas lower-end mix casting and CNC.

I'm not sure the quoted statement is fully correct, CNC and Casting are processes and each have advantages as well as capabilities the other cannot easily replicate. (Try casting threaded holes -- there are ways to add threading to a casting process, but it's not the same.)

I think the original quote intended to convey the following idea, instead of never CNC: if you have a high-volume product, while CNC machining can effectively handle shaping operations, casting will be less expensive for shaping in the long run, leaving CNC to more difficult to cast operations and final product fit.

In the camera market, there are tons of companies selling equipment in thousands and tens of thousands of units that are fully-CNC'ed and no casting. (See Kessler, Dynamic Perception, CamBLOCK, etc.)

drone··on Nikola Motor Company
The answer to #1 provides some insight as to what might make this play a little more interesting. Reading into the truck page, check out this gem:

"At Nikola Motor Company, we’ve decided to invest in American energy. Nikola owns the rights to its own natural gas wells along with the Nikola One fleet that transports the natural gas from the wells to the stations. With 7 wells on a single property, Nikola can pump out millions of gallons of clean natural gas each day. Nikola plans on having more than 5 well sites for redundancy throughout the United States. Complete vertical integration removes market uncertainties and allows Nikola Motor to control its own prices and keep them that way for Nikola customers. Nikola bypasses all the gas companies, liquifies the gas on site, then delivers it to the station through its fleet of electric trucks."

The trucks appear, in part, to be a method of arbitraging future LNG prices which have been going down, and can be expected to continue to fall for the foreseeable future as more and more wells keep coming on line.

drone··on Lyft and Uber to Halt Operations in Austin After Voters Reject Proposal
In Texas, there are established commercial businesses which provide finger printing services already using a quick electronic process [0]. In my experience, it takes about 5 minutes to get done w/ an appointment. Uber already has a page set up for their Houston drivers to schedule an appointment via a Morpho Trust office [1].

I doubt that the city would accept Uber doing its own fingerprinting. In Houston, the city's argument was that Uber's background check failed to catch felons, persons convicted of sexual assault, and homicide [2].

drone··on The Neurofix
Sadly, even exercise and good living doesn't always work. I have a family member living with dementia right now who lived a model life as far as diet (vegetarian), exercise (daily for life), no drinking or drugs, and an overall focus on doing everything possible to be as healthy as possible. Conversely, my own grandfather watched all of his coworkers die from cancer due to the chemicals they worked with, was generally sedentary, and lived into his nineties with no major degenerative diseases.

That said, I agree that one is more likely to have positive late-life outcomes if one chooses to live more healthfully in younger life.

drone··on How I Made a Cheap PCB
Hi there! I am the founder of MacroFab, and I'm happy to answer any questions. Quick summary though: we do US-based (in Houston, TX) assembly, we offer low-cost prototyping options along with production quantities all with real-time quoting down to the component level, build-box assembly, programming, testing, inventorying, and fulfillment. We have APIs to allow direct integration and we have a number of integration partners coming online this year.
drone··on SpoonRocket shuts down
I think part of the problem here is failing to use correct terminology. We might say, in GAAP terms:

* For 40% of the orders, they achieve a positive gross margin * We anticipate reaching positive gross margin on 100% of orders by the end of year * Even after reaching positive gross margins, non-COGS operating costs are sufficiently high to result in a negative EBITDA

drone··on How Hackers Stole $100M from the New York Fed
Play craps? You'll cycle chips pretty much all of your chips, and chips you throw to one side get replaced with chips from another side when making field bets -- for example.

Typical player tracking is done through comp cards, where they account for your buy-ins at the table, and buy out at the cashier.

drone··on SimpliSafe Alarm System Replay Attack
It depends on what one means by "garbage", but I've found that hard-wired systems (i.e. wires for all sensors) backed by something like the standard Honeywell Ademco Vista series attached to a real cellular uplink works most reliably. We use them at home and at business, and for what a home security system is supposed to do (make noise when an intrusion occurs and send a signal out so that you know about it) its the most reliable setup I've ever used. (Not to mention, provides a ton of options for "hacking" your system to your needs.)

Just, whatever you do, do NOT let some crazy internet-connected service, like XFinity Home hook up to it. All of your reliability goes out the window the second they hook up their stupid takeover devices.

drone··on A house that costs $20k
A lot of the poor, rural, families these low-cost homes are targeted at are living on land owned by the family for generations. They often do small-scale farming or large-scale gardening (depending on your definition) and hunting/gathering on the property for food.

In many cases, there will be multiple generations of the family living in separate houses on the same property. At least, these things were all true when I lived in family property in West Virginia in the 80's. We had four houses on about 200 acres in a valley, nearly an acre of garden, and other relatives would regularly stop by from nearby valleys on hunting trips, sharing what they managed to catch for what we managed to grow.

drone··on Inside the Goth Chicken: Black Bones, Black Muscle and a Black Heart

drone··on Born in the ’70s: Jack Ma’s Memo to Alibaba Employees on Management Shuffle
Interestingly, a newer book with a different focus, Boards that Lead [0], lays the blame on the ultimate demise/downfall of those two companies on the boards as instructive of things not to do. Both books are quite good, and worth reading -- even if it is better not to treat them like roadmaps =)

drone··on Hey startup parasites: We don't have time for you
Yeah, we had the same thing with the web summit run by the same people who run Collision. "Hey, we think you've got a great startup, and we'd love to talk to you to see if you qualify for our start-up track."

After the interview, of course, they follow up with the exact same sort of line:

"As you know, we can't invite everyone. However, I'm happy to say that it seems XXX is doing great things in an exciting space and you've been selected for XXX, the later stage startup track at XXX."

Followed by this...

"Your code will reduce the cost from €12,950 to €1,950. As discussed the package includes 3 attendee tickets, plus a complimentary exhibition stand for one of the three days."

Afterwards, if you interact with them in any way, expect to get 5-15 average spam mails a week with "Guess who's going to be at our conference!" If you unsubscribe from the list, it seems like they just invent another conference to spam you with.

Not surprisingly, their "exhibitor" costs rival some of the largest and most successful industry conference costs, even though, in the case of the one I inquired about, it it was the first event that they had put on in that track. Afterwards, of course, "oh, but you qualify for our start-up track which lets you stand in this hall for one day for $5,000!"

Agree with earlier poster to avoid.
