]]>Alcohol may prevent amphetamine action by impairing central insulin signaling.
These alterations produced by alcohol cause severe hepatic and central nervous system insulin resistance as the cells fail to adequately transmit signals downstream through Erk/mitogen-activated protein kinase (MAPK), which is needed for DNA synthesis and liver regeneration, and phosphatidylinositol 3-kinase (PI3K), which promotes growth, survival, cell motility, glucose utilization, plasticity, and energy metabolism
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4550293/
Because insulin and PI3K signaling have been shown to fine-tune DAT cell surface expression (Garcia et al., 2005; Wei et al., 2007), it is possible that inhibition of PI3K signaling in vivo, by reducing DAT cell surface expression, inhibits AMPH-induced DA efflux. Selective inhibition of PI3K via LY294002 results in a dramatic reduction in AMPH's ability to elicit DAT-mediated DA efflux in heterologous cells, dopaminergic neurons, and in vivo within the striatum of rats as measured by both in vivo voltammetry and fMRI (Lute et al., 2008; Williams et al., 2007).
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3518862/
Caffeine-amphetamine interactions were studied to determine whether attenuation of amphetamine-induced activity by caffeine pretreatment (30 mg/kg) is the result of increased or decreased sensitivity to amphetamine. Caffeine pretreatment attenuated amphetamine activity in the rats without producing a horizontal shift in the dose-response curve. Results support a reduction in sensitivity to amphetamine. A cross-tolerance design revealed an asymmetrical interaction between caffeine and amphetamine. Multiple caffeine treatments (30 mg/kg) produced tolerance and attenuation of subsequent amphetamine activity (1.5 mg/kg). Amphetamine did not produce tolerance or affect subsequent caffeine-induced activity.
To investigate mechanisms, additional animals were pretreated with the adenosine agonist, 2-chloroadenosine (2.5 and 10 mg/kg), before being challenged with NS, 90 mg/kg cocaine, or 42 mg/kg amphetamine. Pretreatment with 2-chloroadenosine had no affect in reducing cocaine or amphetamine toxicity. Combination pretreatment with caffeine and 2-chloroadenosine potentiated cocaine toxicity. The phosphodiesterase inhibitor, pentoxifylline, did not potentiate cocaine toxicity. The authors conclude that caffeine potentiates the acute toxicity of both cocaine and amphetamine, and that the failure of 2-chloroadenosine to alter this suggests that the toxicity of the stimulants cocaine and amphetamine may be modulated by nonspecific rather than specific adenosine- or phosphodiesterase-induced mechanisms.

Yes, Coinbase can send Bitcoins from your wallet without your permission.
Last week, Coinbase announced a promotion where new Coinbase accounts registered with a .edu address would receive $10 worth of Bitcoins for free.
My friend John (named as so for the purpose of this post) and I realized that not everyone we knew were going to be interested with Bitcoin. We came up offering $5 upfront for the Bitcoins each person received if they signed up for a Coinbase account.
John was able to get 18 interested individuals in sending him their account balances, coming up to a total of .47005 Bitcoins. I however had a less impressive amount.
Later, John received an email notification from Coinbase that someone had emptied his wallet balance.
That someone was Coinbase. Make no mistake that Coinbase in all intents and purposes is not a traditional wallet. They will "spend" your coins if it suits their interests, as is seen here.
Keep all of this in mind when we head towards increased adoption of Bitcoin.
Oh Grum, why did you choose to serve these fans such unfortunate news?
You can charge for hosting servers, but not for gameplay features.

So if you haven't been following the Minecraft drama in the past few hours (or days), you might be interested to know that Mojang is currently in the works to shut down Minecraft servers that give perks to players who pay, whether these be donations or not. Players and server operators are not happy.
As far as I currently know, and as the situation currently develops, Erik Broes (@_grum) on behalf of Mojang chatted up with server operators, namely MCPVP, Hypixel, and other ops to verbally serve them a cease and desist on their operations. I've been able to grab up a few snippets from Skype logs and from my friends [1].
Erik Broes: doesn't matter at all, based on plugins or not, you cannot make money with Minecraft without our permission :)
[...]
Erik Broes: running servers is *NOT* A BUSINESS*
Even threatening the presence of lawyers.
Erik Broes: We'll ask nicely and then send really mean lawyers :)
It doesn't take a Bitcoin sheep to understand that Mojang is trying to rid of the community that currently surrounds paid servers. The community which currently surrounds pay-to-win servers is no small speck.
Erik Broes: It just made me sad someone spent $1200 on a server, he could have given 44 kids a copy of minecraft rather than paying again for pixels he already owned
While spending $1,200 on a server is odd in the grand scheme of things to begin with, it isn't unheard of in the gaming world. Often, you don't find individuals who spend several thousand on a hobby, such as rocketry or rc airplanes peculiar. But that's just what Minecraft is, a hobby. One serves an individual's satisfaction; the other is straight up charity.
When was the last time you donated $1,200 to charity?
While it is purely of Mojang's right to enforce their policies on their intellectual property, many players believe that this will have disastrous effects for the community.
A significant player base of Minecraft revolves around large servers (500+ slots) that take huge amounts of resources to run. Server costs, custom development work on plugins reach in the several thousands of $ a month to maintain a server of this size. Each is like an individual startup. Hundreds of servers of this size exist as to date.
Servers of this size usually operate on the model that users pay for game perks or in-game cosmetic items to receive appearance benefits. Models like these generally work well enough to support costs and provide a working salary for those who work full-time on the servers [2].
The issue is that Mojang is officially on the stance that server operators can only receive donations, and that no incentive for these donations/benefits can be given.
Eric Broes: donations are no problem, but only in that purest sense, you get *NOTHING* back for a donation
Pure donations at the current time are an unsustainable solution for servers of these size. With nothing to be given in return, many users are given no incentive to donate. Similar to the events of a deflationary spiral, the majority of servers whose cost to maintain is higher than that of a vanilla server will inevitably shutdown.
Development for multiplayer servers will have to rely on the goodness of developers to provide something other than the Vanilla servers that often many players get tired with.
It's interesting that this clause has been in the the EULA (end user license agreement) since at least last December, however it had never been enforced until now. It is likely that Mojang had been waiting to make this move for a while, but did not have the nerve to do so.

MINECRAFT END USER LICENCE AGREEMENT
[...]
So the one major rule is that (unless we specifically agree it – such as in brand and asset usage guidelines) you must not:
- give copies of our Game to anyone else;
- make commercial use of anything we‘ve made;
- try to make money from anything we‘ve made; or
- let other people get access to anything we‘ve made in a way that is unfair or unreasonable.
I was hit with a $48.96 debit on my Namecheap account balance yesterday for 17 WhoisGuard renewals.
Most of the domains that the WhoisGuard subscriptions were protecting were set to expire, and so each domain's auto-renew was turned off. Yet I was still charged.
Feeling outraged, I contacted their support trying to get the charges back credited to my account - that money would be better spent on domain renewals on some 40 pointless domains than on WHOIS privacy nonsense.
Namecheap's support great as always, granted me a one-time exception to their all-sales final policy. The support representative spent some 20 minutes on what seemed like deleting and refunding each WhoisGuard subscription individually.
It turns out that all WhoisGuard subscriptions are regarded as their own entity, and are not affected by the state of the domain (if any) it is protecting.
I turned off auto-renew on the rest of my domains, but it was painful. I couldn't help but feel that Namecheap had an agenda out to milk money out of their WhoisGuard customers.
Unlike domains, there was no real way to manage the rest of the 23 WhoisGuard subscriptions I had left without clicking on each subscription individually.
Namecheap's site is awfully slow most of the time. Turning off auto-renewal for your WhoisGuard subscriptions is a 40 minute task.
Great! Just what I needed.
Bitstamp, the current largest Bitcoin exchange in volume, tweeted
yesterday that their customers should be careful with phishing emails
sent to them impersonating Bitstamp.
ATTENTION all Bitstamp USERS - new phishing attempt. Ignore all email with the subject "Bitstamp trading will be suspended for 24 hours".

This is really concerning. How did these attackers gain access to the email addresses of Bitstamp's customers?
I remembered that I stumbled upon a /r/bitcoin thread
a few days ago from a user that warned users of suspicious emails from
Bitstamp. He was wondering how the attackers were able to acquire his
email, since he had given Bitstamp an address unique to them (e.g.
[email protected]).
In the thread, eleuthria [1]
confirmed that Bitstamp's support had been somehow compromised through
his experiences with support.
Bitstamp's email list was confirmed stolen ~2 weeks ago, when a boatload of emails claiming to be from [email protected] (but not sent from any of the BTC Guild mail servers) went out talking about a 3.201 bitcoin transfer. After replying to the people shouting at me for being a scammer, I was eventually able to narrow the source of the leak to Bitstamp at the very least, and likely a few other sources on top of it.
I informed Bitstamp that they had at least a breach on their email list, if not the rest of their system. At first they denied it, but in a follow up they eventually admitted to it.
They then sent out a little security update email mentioning 2FA/password security.
It's already been 2 weeks, and Bitstamp hasn't given any transparency into this issue. It sure feels like they're pulling off a Linode, and trying to sweep this under the rug.
Bitstamp, you're now the replacement to MtGox. Don't screw this up.
[1]: If you don't know eleuthria, he operates BTC Guild, one of the first and largest Bitcoin mining pools.
At approximately 18:25 UTC, Bitstamp's trading engine reported a matched market order approximately 7% below the highest bid.
In an optimal matching scenario ~4,000 Bitcoins were needed to strike the price of 633.64. However, the volume at 5 minute interval was only 89.27 Bitcoins.
Something is seriously wrong with Bitstamp's matching engine, and apparently it's not the first observation by the community.
]]>The following was imported from my old blog.
Earlier this week, Ozcoin, a popular Bitcoin pool, had their payout script hacked, leaving them in the negatives of ~900 Bitcoins (~$132,000 USD). Today, the operator of StrongCoin, a online Bitcoin wallet, notified the Bitcoin community that he had intercepted the pool's coins from the attacker using their service, and sent them back to Graet [1].
Public Disclosure.
On Saturday afternoon I was notified that Strongcoin was holding 568 BTC believed to be from the Ozcoin theft. Everytime you make a payment from StrongCoin the fee goes to 1STRonGxnFTeJiA7pgyneKknR29AwBM77 so any payments from strongcoin held accounts are easily traced back to the site
I was asked by 2 separate people on this forum if I could hold the funds (Sorry to the people I didn't reply to). The evidence that these funds came from the heist seemed plausible to me.
At 8am yesterday morning the funds were intercepted when the user made a payment.
https://blockchain.info/address/1DsFCAZaxhJ9YGw5X8NCW9VkSMDZMyXzMF
I've spoken to the user in question over email. The user says he sold a car for BTC but can't reveal who to due to an NDA agreement.
Graeme and I had a conversation over the phone and some evidence came to light, that to me, made it very likely the user I have contact with was connected to the heist. I'm not going to reveal any details of the user accept to legal authorities if asked. I believe we should abide by due process.
I have sent a link to this post to the user so he/she can comment. Otherwise in the next few hours I will return the funds to Graeme, he can then decide what happens to those funds.
While this may appear to be a seemingly nice gesture, there are all sorts of wrong in this in incident. Lets look a bit closer on what StrongCoin is.
Then strong encryption became available to the masses, and trust was no longer required. Data could be secured in a way that was physically impossible for others to access, no matter for what reason, no matter how good the excuse, no matter what.- Satoshi
