DC Entertainment Won't Allow Superman Logo On Murdered Child's Memorial Statue

koreanbabykilla Re:Superman logo is a Trademark (249 comments)

You are retarded, they could easily issue a no-cost perpetual licence for this. They just don't want to. There are ZERO legal issues stopping them. Licensing your trademark does not make you lose it. It is not going after unlicensed uses. I don't know how the fuck you have such a low UID and haven't read this here 100000 times.

Google, Detroit Split On Autonomous Cars

koreanbabykilla Re:US car companies are NOT finance companies (236 comments)

"Just because Google has a bunch of smart people working for them doesn't mean they understand the business of selling cars."

Just because Tesla has a bunch of smart people working for them doesn't mean they understand the business of selling cars.

hmmmmm.......perhaps you may want to rethink that last part?

i feel bad for you. You have really never read a book that you again want to read years or decades later? There are many thousands of books i have read many times. You are either young, or base your reasoning on only having read what you can get from the magazine section of the grocery store.

Cracking Atlanta Subway's Poorly-Encrypted RFID Smart Cards Is a Breeze, Part II

koreanbabykilla Re:The REAL value of the transit system (170 comments)

where i live the bus is always at around 10% capacity. The people on it are low income people with free passes. They charge me more to get to work than it costs in gas. I do only get 15 mpg, but own the car outright. Charge me 1 dollar there and back and i can put up with the order of magnitude time cost increase. I bet busses would be full and not just a crazy tax sinkhole then....

Why NASA's Budget "Victory" Is Anything But

koreanbabykilla Re:Neil DeGrasse Tyson says a 1% increase for mars (267 comments)

Not a huge Tyson fan, but saying methane was not mentioned is a lie. It was mentioned at least once when talking of the permafrost melting and the organic matter decomposing. He also didn't say climate was easy to predict, you just pulled that out of your ass. The dog thing worked great to help my kids understand the difference between climate and weather, just as it was intended to.

'Godfather of Ecstasy,' Chemist Sasha Shulgin Dies Aged 88

koreanbabykilla Re:It's just sad... (164 comments)

Phenethylamines. http://en.wikipedia.org/wiki/P...

Phenethylamine /fnlmin/ (PEA), -phenethylamine, or phenylethylamine is an organic compound and a natural monoamine alkaloid, a trace amine, and also the name of a class of chemicals with many members well known for psychoactive drug and stimulant effects.[1] Phenylethylamine functions as a neuromodulator or neurotransmitter in the mammalian central nervous system.[2] It is biosynthesized from the amino acid phenylalanine by enzymatic decarboxylation. In addition to its presence in mammals, phenethylamine is found in many other organisms and foods, such as chocolate, especially after microbial fermentation. It is sold as a dietary supplement for purported mood and weight loss-related therapeutic benefits; however, orally ingested phenethylamine experiences extensive first-pass metabolism by monoamine oxidase B (MAO-B), which turns it into phenylacetic acid. This prevents significant concentrations from reaching the brain in low doses.[3][4]

The group of phenethylamine derivatives is referred to as the phenethylamines. Substituted phenethylamines, substituted amphetamines, and substituted methylenedioxyphenethylamines (MDxx) are a series of broad and diverse classes of compounds derived from phenethylamine that include stimulants, psychedelics, and entactogens, as well as anorectics, bronchodilators, decongestants, and antidepressants, among others.

http://www.erowid.org/archive/...

and last in honor of shulgan, his synth:

http://www.erowid.org/library/...

SYNTHESIS: (from MDA) A solution of 6.55 g of 3,4-methylenedioxyamphetamine (MDA) as the free base and 2.8 mL formic acid in 150 mL benzene was held at reflux under a Dean Stark trap until no further H2O was generated (about 20 h was sufficient, and 1.4 mL H2O was collected). Removal of the solvent gave an 8.8 g of an amber oil which was dissolved in 100 mL CH2Cl2, washed first with dilute HCl, then with dilute NaOH, and finally once again with dilute acid. The solvent was removed under vacuum giving 7.7 g of an amber oil that, on standing, formed crystals of N-formyl-3,4-methylenedioxyamphetamine. An alternate process for the synthesis of this amide involved holding at reflux for 16 h a solution of 10 g of MDA as the free base in 20 mL fresh ethyl formate. Removal of the volatiles yielded an oil that set up to white crystals, weighing 7.8 g.

A solution of 7.7 g N-formyl-3,4-methylenedioxyamphetamine in 25 mL anhydrous THF was added dropwise to a well stirred and refluxing solution of 7.4 g LAH in 600 mL anhydrous THF under an inert atmosphere. The reaction mixture was held at reflux for 4 days. After being brought to room temperature, the excess hydride was destroyed with 7.4 mL H2O in an equal volume of THF, followed by 7.4 mL of 15% NaOH and then another 22 mL H2O. The solids were removed by filtration, and the filter cake washed with additional THF. The combined filtrate and washes were stripped of solvent under vacuum, and the residue dissolved in 200 mL CH2Cl2. This solution was extracted with 3x100 mL dilute HCl, and these extracts pooled and made basic with 25% NaOH. Extraction with 3x75 mL CH2Cl2 removed the product, and the pooled extracts were stripped of solvent under vacuum. There was obtained 6.5 g of a nearly white residue which was distilled at 100-110 C at 0.4 mm/Hg to give 5.0 g of a colorless oil. This was dissolved in 25 mL IPA, neutralized with concentrated HCl, followed by the addition of sufficient anhydrous Et2O to produce a lasting turbidity. On continued stirring, there was the deposition of fine white crystals of 3,4-methylenedioxy-N-methylamphetamine hydrochloride (MDMA) which were removed by filtration, washed with Et2O, and air dried, giving a final weight of 4.8 g.

(from 3,4-methylenedioxyphenylacetone) This key intermediate to all of the MD-series can be made from either isosafrole, or from piperonal via 1-(3,4-methylenedioxyphenyl)-2-nitropropene. To a well stirred solution of 34 g of 30% hydrogen peroxide in 150 g 80% formic acid there was added, dropwise, a solution of 32.4 g isosafrole in 120 mL acetone at a rate that kept the reaction mixture from exceeding 40 C. This required a bit over 1 h, and external cooling was used as necessary. Stirring was continued for 16 h, and care was taken that the slow exothermic reaction did not cause excess heating. An external bath with running water worked well. During this time the solution progressed from an orange color to a deep red. All volatile components were removed under vacuum which yielded some 60 g of a very deep red residue. This was dissolved in 60 mL of MeOH, treated with 360 mL of 15% H2SO4, and heated for 3 h on the steam bath. After cooling, the reaction mixture was extracted with 3x75 mL Et2O, the pooled extracts washed first with H2O and then with dilute NaOH, and the solvent removed under vacuum The residue was distilled (at 2.0 mm/108-112 C, or at about 160 C at the water pump) to provide 20.6 g of 3,4-methylenedioxyphenylacetone as a pale yellow oil. The oxime (from hydroxylamine) had a mp of 85-88 C. The semicarbazone had a mp of 162-163 C.

An alternate synthesis of 3,4-methylenedioxyphenylacetone starts originally from piperonal. A suspension of 32 g electrolytic iron in 140 mL glacial acetic acid was gradually warmed on the steam bath. When quite hot but not yet with any white salts apparent, there was added, a bit at a time, a solution of 10.0 g of 1-(3,4-methylenedioxyphenyl)-2-nitropropene in 75 mL acetic acid (see the synthesis of MDA for the preparation of this nitrostyrene intermediate from piperonal and nitroethane). This addition was conducted at a rate that permitted a vigorous reaction free from excessive frothing. The orange color of the reaction mixture became very reddish with the formation of white salts and a dark crust. After the addition was complete, the heating was continued for an additional 1.5 h during which time the body of the reaction mixture became quite white with the product appeared as a black oil climbing the sides of the beaker. This mixture was added to 2 L H2O, extracted with 3x100 mL CH2Cl2, and the pooled extracts washed with several portions of dilute NaOH. After the removal of the solvent under vacuum, the residue was distilled at reduced pressure (see above) to provide 8.0 g of 3,4-methylenedioxyphenylacetone as a pale yellow oil.

To 40 g of thin aluminum foil cut in 1 inch squares (in a 2 L wide mouth Erlenmeyer flask) there was added 1400 mL H2O containing 1 g mercuric chloride. Amalgamation was allowed to proceed until there was the evolution of fine bubbles, the formation of a light grey precipitate, and the appearance of occasional silvery spots on the surface of the aluminum. This takes between 15 and 30 min depending on the freshness of the surfaces, the temperature of the H2O, and the thickness of the aluminum foil. (Aluminum foil thickness varies from country to country.) The H2O was removed by decantation, and the aluminum was washed with 2x1400 mL of fresh H2O. The residual H2O from the final washing was removed as thoroughly as possible by shaking, and there was added, in succession and with swirling, 60 g methylamine hydrochloride dissolved in 60 mL warm H2O, 180 mL IPA, 145 mL 25% NaOH, 53 g 3,4-methylenedioxyphenylacetone, and finally 350 mL IPA. If the available form of methylamine is the aqueous solution of the free base, the following sequence can be substituted: add, in succession, 76 mL 40% aqueous methylamine, 180 mL IPA, a suspension of 50 g NaCl in 140 mL H2O that contains 25 mL 25% NaOH, 53 g 3,4-methylenedioxyphenylacetone, and finally 350 mL IPA. The exothermic reaction was kept below 60 C with occasional immersion into cold water and, when it was thermally stable, it was allowed to stand until it had returned to room temperature with all the insolubles settled to the bottom as a grey sludge. The clear yellow overhead was decanted and the sludge removed by filtration and washed with MeOH. The combined decantation, mother liquors and washes, were stripped of solvent under vacuum, the residue suspended in 2400 ml of H2O, and sufficient HCl added to make the phase distinctly acidic. This was then washed with 3x75 mL CH2Cl2, made basic with 25% NaOH, and extracted with 3x100 mL of CH2Cl2. After removal of the solvent from the combined extracts, there remained 55 g of an amber oil which was distilled at 100-110 C at 0.4 mm/Hg producing 41 g of an off-white liquid. This was dissolved in 200 mL IPA, neutralized with about 17 mL of concentrated HCl, and then treated with 400 mL anhydrous Et2O. After filtering off the white crystals, washing with an IPA/Et2O mixture, (2:1), with Et2O, and final air drying, there was obtained 42.0 g of 3,4-methylenedioxy-N-methylamphetamine (MDMA) as a fine white crystal. The actual form that the final salt takes depends upon the temperature and concentration at the moment of the initial crystallization. It can be anhydrous, or it can be any of several hydrated forms. Only the anhydrous form has a sharp mp; the published reports describe all possible one degree melting point values over the range from 148-153 C. The variously hydrated polymorphs have distinct infrared spectra, but have broad mps that depend on the rate of heating.

Need some advice on VPN

koreanbabykilla koreanbabykilla writes  |  about a year ago

koreanbabykilla (305807) writes "I do lightweight IT support for a small shop of 2 dentists. I have firewalled the crap out of of everything. This is now causing an issue as the media server in a closet is now wanting to be used as a client to schedule appointments and such. I think it's a horrible idea to switch up the VLAN's so the wifi and the lan can communicate. I tried openvpn before here and the speed made it unacceptable. should i put the wifi back on the bridge or does anyone know of a VPN solution that would be accepable?
Understand this is for a friend for free so the "Hire a professional to do it" answers are not an answer.(I'm still expecting most answers to be this)
What VPN tech do you use when you need it to be responsive? Speed is important as the front desk girls hate a second or 2 of latency.
Also, dentrix(the dental software used) needs windows so windows software is required.
if anyone has tips for moving to opendental from dentrix, If i can get it working thats an option. They just moved to all digital X-rays so getting wifi clients working would be sweet.
I have the wifi and the wired on separate subnets now, How would you handle this?"
