Comment Re:DHCP? Huh? (Score 1) 154

Exactly. All that is required is that the packet reaches the intended destination. The easiest way to do that on a TCP/IP network is the magic packet sent to one of the broadcast addresses (either network specific i.e. 192.168.0.255 or the general purpose one: 255.255.255.255). Every switch knows how to handle network broadcasts (and every hub, though I haven't seen an actual network hub in ages since small switches are commodity hardware now, transmits every packet to every connected port).

With the exception of professions where there is either very little expansion of knowledge, but a vast knowledge base (such as literary professions) or an ever increasing knowledge base where knowledge is seldom replaced (such as medical professions), most of what a college degree proves is that you have learned how to learn. This is especially true in the IT professions where the industry changes so quickly that the curriculum is already multiple generations behind by the time changes have been approved.

My advice for those entering the IT professions: Try to get in with a start-up. The work is not stable, but they will be more willing to take a risk on those with less experience (due to the fact that the more experienced will be looking for something more stable.)

Using VNC, one can now ... power up,

Before I VNC in to power up the box, I need DHCP running so I have an IP address to connect to. No problemo, I'll just power up the box to get a DHCP address before I power up the box to power up the box. Its turtles all the way down.

I'll take it you've never heard of Wake-on-LAN. Third-party services such as LogMeIn actually can turn on remote machines as long as there is another computer on the network with LogMeIn installed. That doesn't even require an IP address. It's a packet addressed to the MAC of the NIC (which is why the originating packet needs to be on the same network).

...and then once you have learned what you set out to learn by programming in C, immediately stop programming in it unless you are doing some heavy-duty programming (like writing an OS or bleeding-edge game development) You can write robust apps in nearly any language, but the language you are using when you make a mistake (and you will make mistakes) will determine what happens. Screw up in Python, Perl, BASIC, Java, etc. and your app will crash. Screw up some memory management in C or C++ and your OS will crash.

You are aware that visible light is also electromagnetic radiation (as well as infrared and ultraviolet - both provided in gratuitous amounts by the sun... far more than produced by any artificial light source)

Of course the back pain reported by workers of electronics stores has absolutely nothing to do with the fact that they are likely moving heavy objects (probably without taking proper precautions to prevent injury) and are on their feet for most if not all of their shifts.

Ignorance does not improve the credibility of your field.

Here's a logical usage taxation for vehicles: Tax the tires. They have a limited lifespan which is already measured in miles. Additionally, the lifespan is reduced if they are not maintained properly (which also leads to increased wear on the roads). Wear out the tires sooner, you'll have to buy new tires sooner, which means that more taxes will be paid for higher roadwear vehicles. The more tires your vehicle has, the more wear you are likely placing on the roads, and thus the more taxes your vehicle will be providing for road maintenance. You can even have varying taxes based on the intended usage of the tires: Farm tractor tires would pay less in road maintenance taxes (since they spend most of their time off the road). Racing tires would also pay less (perhaps almost none) since they would rarely, if ever, be used on public roadways.
