Network operators basically choose bridging vs routing based on how fast they want it to go and how much they hate configuring DHCP servers, which they really hate very much, which means they use bridging as much as possible and routing when they have to.

It’s hard to give a firm but general answer, because every possible perversion has been visited on TCP since its inception, and all sorts of people might be inserting RSTs in an attempt to block traffic.

Chlorine trifluoride, ClF₃, or “CTF” as the engineers insist on calling it, is a colorless gas, a greenish liquid, or a white solid. It is hypergolic with every known fuel, and so rapidly hypergolic that no ignition delay has ever been measuredIt is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water —with which it reacts explosively. It can be kept in some of the ordinary structural metals — steel, copper, aluminum, etc. — because of the formation of a thin film of insoluble metal fluoride which protects the bulk of the metal, just as the invisible coat of oxide on aluminum keeps it from burning up in the atmosphere. If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. For dealing with this situation, I have always recommended a good pair of running shoes.

At an inconspicuous signal, one of my henchmen would drop the finger of an old rubber glove into a flask containing about 100 cc of mixed acid —and then stand back. The rubber would swell and squirm a moment, and then a magnificent rocket-like jet of flame would rise from the flask, with appropriate hissing noises. I could usually tell from the candidate’s demeanor whether he had the sort of nervous system desirable in a propellant chemist.

neat trick

lai apčakarētu laptopa waitlistu wi-fi kartei, izrādās, nevajag censties par katru cenu atrast karti no waitlista.

man, piemēram, OS X instalācijai der tikai Atheros 168c:0030 ar subvendor un subsystem ID 103c:1627.
Tāda, HP laptopam paredzētā, zem OS X neiet, neredz nevienu SSID. Savukārt AR9380 tipa kartei pāršūt eprom, lai nomainītu subsystem un subvendor ID, ir sarežģīti, jo nav piemērotu rīku.

Tātad, ņemam AR928X karti, kas strādā zem OS X (tādas ir vairākas), pāršujam vendor ID uz 168c:0030 (ar modificētu iwleeprom), tiekam garām waitlistam.

Pēc tam OS X iestāstam, ka mums tomēr ir tāda karte, kāda tā fiziski ir, ar Fake PCI ID.

Linux pēdējā soļa figņa nav nepieciešama, draiveris pats saprot, kā darbināt dzelzi. Dabiski, Linux vispār nav vajadzīga šāda figņa 🙂
