Do tell us all about the huge labor savings Tesla is running away with[1].

It blows my mind away how you can even begin to compare the predicted reliability of a complex touchscreen interface stuffed with active electronics to dumb buttons and wires with a straight face, let alone what fielded production units only a few years in have clearly demonstrated.

> ...DOORS doesn’t come on the list with Word.

Got to give the hiring manager some credit. Listing DOORS as a proficiency requirement is a sure way to prolong vacancy.

You're reading the job description all wrong...you've got to think like a hiring manager in the defense industry to make any sense of it, i.e. reverse qualification priorities and the actual job you'll be hired to perform will become crystal clear.

> I'd like to say that I'm astonished that modern aircraft still use the 1553 bus...

What's wrong with 1553? It's reliable, battle-tested, and the latest revision C was published 28-Feb-2018. In contrast, the RS-232 PHY dates back to 1960, yet it's quite alive and well in modern commercial devices. As a consolation, be glad you've never had to deal with the monster that is STANAG 5516/MIL-STD-6016...if there was such a thing as a "modern" interface standard whose sheer page count (11,410 pages!) would make any sensible engineer reconsider future career prospects.

Hope you're prepared to swallow; I can think of several dozen young engineers across 5 states (California, Indiana, Florida, North Carolina, and New Jersey) with VAX/OpenVMS domain expertise, myself included. Legacy systems with 30-year lifecycles are a thing...they're just not what most of commercial industry is accustomed to supporting. If you think LM would have an issue filling this position internally (for the right price), you'd be mistaken.

System engineers in the defense industry have an insidious infatuation with SLOC metrics. To the detriment of many a development engineer, CMU SEI hasn't developed a better way to keep them preoccupied.

The only mention of VAX/VME from the job post:

> Experience with troubleshooting equipment such as Pass1000/5000 1553 bus monitor, fiber-optic test equipment, digital storage oscilloscopes, and familiarization with the VAX/VME based computing environment.

Seems apparent to me that the context is development+ATE environment; VME is likely VXI interface to ATE instrumentation. In any case, the VMS and/or VME angle to this job post is the least of any prospect's concerns.

> ...I don't really know what I'm allowed to do, or not, with the project, and that just makes me uncomfortable.

If your interests weren't somehow commercially aligned--be it directly or indirectly--why would it really matter? Perhaps I'm the real radical here who still parades around with a false sense of hacker ethos.

> ...and I then fork it and makes some modifications as part of some non-commercial hobby project, and then the author of the original project sends a DMCA takedown notice against my non-commercial hobby fork, then legally I would not be in a very strong position.

In agreement with the pragmatic implications, but I still genuinely struggle to see the point. The financial constraints of legal defense is what strikes me as the killer of non-commercial hobby projects if the hypothetical scenario would arise; with or without appropriate licensing terms, there's really nothing to stop an original project with the financial means and intent from issuing a DMCA takedown and outspending an unfunded project in legal maneuvering. IANAL but at least it sure does feel that way in my limited experience.

> ...anything that relies on people taking it upon themselves to protect their data is doomed.

This isn't enlightenment...this has been meta since...the internet was born?

> Why do I speak up about it then? Simply because I think clarity in open-source licensing is important.

Fair enough and thanks for clarifying.

To be sure, using the term "risk" in the context of licensing speaks quite clearly in my mind of interests aligned with commercialization (or the prohibition thereof).

My current phone is a Key2. Before that, I had 3 Privs, a handful of Curves, and several Palms.

For me, it has always been about tactile feedback: I habitually text and drive, so a physical keyboard that allows for high accuracy without looking at the screen is an absolute imperative...everything else is a secondary consideration.

Any test is only effective if it's actually performed during acceptance, and there's no requirement provision for such test in any acceptance qualification that I'm aware of.

In either case, it's kind of a shitty test given defense applications aren't constrained to the same EMC regulations as the rest of the commercial world.

Although admittedly ad hominem, I was instantly turned off by the article upon learning Hao Li[1] was solicited to remark in his affiliate capacity with USC.

Would you happen to have a citation for that? Truly interested in knowing if the diff is significant or marginal.

> Move fast and break shit.

Ironically, also a core fighter pilot mantra to the detriment of flightline maintainers and field support engineers alike...you might call it a symbiotic relationship.

Wow they've really jacked the price up!

No disrespect to Saleae's Logic as even their 1st gen product was indeed outstanding value (and may still be at the current price point; software front end is well executed). But to be sure, there's still a significant hardware gap that sets it apart from "the real deal".

Yes, instrumention amps are often used for low-voltage amplification...primarily because the topology enables the elimination of impedance-matched input termination with the distinct benefit of minimizing parasitic load on the UUT. Apparently, readily-available integrated instrumentation amps on the market are designed for relatively low-bandwidth applications as a quick DigiKey parametric search suggests, but the canonical topology itself isn't fundamentally bandwidth-constrained...which is part of the reason why I pointed to max GBW results from the search and left it at that.

No, that's not what I'd be looking for, especially in response to your question with the specific constraint of "an integrated version of a differential amp"; given the sensitivity of the in-circuit measurement application being considered, this effectively suggests integrated instrumentation amp. With your suggestion of what I should be looking for, how would you go about input termination without loading the UUT to the detriment of SI?

The author does indeed briefly discuss his prototypes and even released his Eagle design on GitHub[1] with still more notes.

For the record, I didn't downvote on first response, but your "oh-so-brillant-ones" snark may have earned one.

A quick DigiKey parametric search yields instrumentation amps with GBW <= 35 MHz.

...when using Arathane 5750, in storage, and at ambient temperature. The devil is in the details.

> The advantage of an eutectic alloy is that it’s far easier to get a good-looking joint with it.

Strange how shiny joints were highlighted as opposed to repeatability of automated manufacturing processes and generally lower melting points when compared to alternatives in the same class.

> The application of a conformal coating...can help limit the formation of tin whiskers.

A very misleading statement with more than a few caveats[1].

I suppose that partially explains the historical revisions of this spec[1] circa 2006, including new IP agreement and criteria for "mini" products.

The receptacle shown above "Micro USB" is incorrect; it's a Mini-AB receptacle.

> ...but standard VMs allow the use of standard operating systems that solved all the hard problems decades ago, whereas Docker is struggling to solve those problems today.

What are these supposed "hard problems" the author speaks of?

> what battery can you hold in your hand that can output 50W?

Laptop batteries all day, so to speak...more typically for about an hour of runtime at that power consumption level between recharge. Not quite following your analogy.

  Etsy is the first major online shopping destination to offset 100% of carbon emissions from shipping.*

  *According to research conducted by 3Degrees.

The fine print[1] is interesting. This isn't some save-the-planet-from-the-goodness-of-our-heart-no-strings-attached campaign...if anything, it's a subsidy brokered through a for-profit carbon credit consulting firm designed to directly benefit certain for-profit companies.

> Why should our overburdened local governments carry the cost of picking up a profitable business' garbage?

As an outsider looking in, perhaps because local governments are largely funded by taxpayers, and taxpayers are ultimately the root cause of the litter?

Consider the status quo of litter in countries like Japan and Singapore.

I think if the problem is to be effectively solved, things need to happen on 3 fronts: local government that establishes effective law/infrastructure, companies with cognizance that take meaningful action, and a population with the right cultural values.

Issuing receipts is part of the cost of doing business which requires investments in infrastruture, maintenance, records keeping and reporting. They're a direct liability traceable to and accountable by the business noted.

Furthermore, a business that accepts returns is the cost paid to increase customer confidence; it's called risk mitigation. Any return accepted is revenue rescinded and indirect cost incurred by the business to restock with the aim of winning future conversion.

A business issuing receipts as required by law is a consumer protection mechanism; a business retaining its receipts is for tax compliance.

Your assertion doesn't even make 1st base by simply considering cashier = owner, as is the case of many small businesses; it conflates one possible usecase as the only valid usecase.

If you own and actually live in the house, why would it matter? Property tax and HOI also drop...that's a net win IMHO.
