The whole idea of the grants is to get things going. While Tesla got most of its startup funding from Musk, most high-tech companies need money from either a venture capitalist or, if seen as too risky, some sort of grant.

In general, the funded firms companies were long-shots with a very significant up-sides for the nation and the economy, and the environment if they succeeded. It was completely expected that many would fail. If the odds were not long, most of the companies would have gotten private capitalization.

And, yes, several more may yet fail, but even the failures are far from a complete write-off. Some produced some potentially useful tech that could not be monetized before the cash ran out or the value was clear enough to get private funding.

Time passes and people forget the past (basically before their parents were adults).

Back at the turn of the century (1901, not 2001), according to the US Bureau of Labor Statistics the average work week was 53 hours and the "normal" work week was six 10 hour days. It really didn't change much until 1926 when Henry Ford reduced the work week at Ford Motor Co, to 40 hours, though the average work day had been slowly dropping from 10 to 8 hours before that time. But Ford was most likely the first major company to drop from a six to five day work week.

So, yes, people CAN work 60 hours a week and your grandparents (or great grandparents) probably did unless they were farmers. Farmers worked longer hours.

Thank you for that. Very informative.

Do modern switches signal fake collisions to attached ethernet devices when their switch memory is exceeded?

No. 802.3 added flow control to the spec and that is the only standard method of dealing with this. It is optional and not all devices support it.

Faking collisions is not really practical as a collision is signaled from the transceiver, which used to be a separate physical device, to the MAC (Media Access Control) of the transmitting system. There is no mechanism on Ethernet to support sending a collision to a remote system. If running half-duplex (again, mostly obsolete), you could set your transmit line to block the transmitter, but that would trigger an error (collisions are not errors) that would disrupt the transmission and result in a packet being dropped. This would be way to disruptive, though dropping a packet due to lack of buffer space would be similarly disruptive.

This all gets into very complex issues as to much buffer space will break TCP congestion detection and severely impact performance. This is not for forum to discuss these issues, so I'll stop here, but you can search for buffer bloat" for lots of information.

I also highly recommend the use of the Netalyzer tool from ICIS.

MAC addresses specify the backoff time for collisions on a LAN and aren't used at "worldwide" scales. They get stripped by the first router that sees them.

MAC addresses have nothing to do with collision back-off time. The back-off time is an algorithmically specified value that depends on the number of collisions (up to 16) that have occurred while attempting to transmit a frame and a random number. Collisions only occur on half-duplex Ethernet which is not normally used on modern LAN implementations. They are dropped (along with the entire frame header and CRC) by the first layer 3 (routing) device to process the frame, but are potentially used globally when an Ethernet frame is wrapped in another frame such as in some VLANs and increasingly popular Software Defined Networks (SDNs). Since they are guaranteed globally unique, they can be very handy for many things.

Only hardware vendors that need to provide unique collision avoidance characteristics on any customer's LAN need MAC address allocations.

Again, MAC addresses have noting to do with collisions and most LANs installed in the past decade have no collisions. They are used for addressing at layer 2 of the OSI reference model (Data-link). They are not actually a part of the Ethernet (IEEE 802.3) spec, but of a more global specification for creating globally unique hardware identifiers for network devices (IEEE 802) and are used by several LAN types which never had collisions (E.g. token ring, MAP (EtherBus), and FDDI).

As has already been pointed out, 16 million is the SMALLEST block of MAC addresses assignable, so this is far, far from massive. It does indicate that they plan on providing a globally unique ID for every machine which may or may not be actually used for addressing purposes.

For some reason nobody considers "I have no idea, we're still investigating" an appropriate answer.

Actually, almost everyone involved in some official capacity gives that answer. But that is not what the press wants, so they keep asking (Reporter: "Do you suppose speed could have been an issue?") until someone says something else that the reporter considers interesting (Tired cop: "It's possible") and uses that quote, or some mangled version of it. (Press: "Speed may have led to fatal accident").

I've been horribly misquoted by reporters and stopped talking to them about a decade ago.

Gee, isn't that the lesson of Google's initial success? Keep it simple and clean. No need for eye candy and extra bells and whistles. They add bugs and detract from the purpose of the site. As time has gone on, Google has drifted away from this concept, but the KISS principle remains valid and clearly had worked well for Kentucky.

Web sites, especially those with a single purpose, don't need 7 fonts, cool graphics, Flash flash, Java, or even CSS. Not that any of these (excepting Flash flash) are bad, but too many web designers seem to think that they are mandatory. The cost in development times, reliability, and ease of use is only justified by ego of developers and their managers. The purpose of the site is to provide important information and not to make health insurance look sexy!

IANAL, but...

"Illegal' is not the correct term. Being an undocumented resident of the US is not a criminal act. It really can't be because that would require engaging the full criminal justice process which would be totally impossible to scale. Instead it is a civil issue with no penalties other then being removed from the US. Deportation can be done quickly and with minimal overhead. (This has both good and bad sides as citizens have been deported on occasion.)

So undocumented IS the correct term. I suppose "extra-legal" would also be correct, but that is mostly a legalese term and is less specific than "undocumented".

Again, wtf are you on about? Mint didn't fork GNOME 2. They forked GNOME 3 and created a new DE based on GTK3. The GNOME 2 fork is called Mate and is independent of Linux Mint.

Seriously, no one is going to take you seriously if you can't even get the basics straight.

Lots of pot calling the kettle black. Mint has two DEs, GTK3 (but not really a Gnome3 fork) based Cinnamon, and Gnome2 fork MATE. While Cinnamon is GTK 3 based and certainly uses Gnome 3 code, it has very little similarity to Gnome3, retaining the configurability of Gnome2 rather then shoving someone's idea of how you should work down your throat.

The USPS does not promise that "they will deliver through rain, sleet, snow or hail". That "promise" was just a phrase carved into the New York City Post Office and 8th and 33rd. The actual sentence is "Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds."

According to the National Postal Museum , the USPS, the successor to the Post Office Department, has no official motto and there are remarkably few guarantees offered by the quasi-governmental organization.

People seem unable to read papers any longer. This is especially true of the news media. The study on earthquakes repeatedly pointed out that there was NO evidence that fracking itself led to earthquakes. It said that the practice of pumping the toxic waste from fracking into deep wells for disposal, a common, but not universal practice, could and did lead to quakes.

Back in the mid 1960s Colorado experienced a series of quakes, some strong enough to cause damage. Those earthquakes were tracked to the use of deep well disposal at the Rocky Mountain Arsenal. The well was used for disposal of chemical warfare agents (toxic gases and their components). The strongest was felt quite strongly in Trinidad, CO, some 200 miles south of the well. I grew up there and felt it personally. This led to the discontinuation of this disposal method.

I am simply amazed that half a century after this well documented and researched event that it seems to have been forgotten.
