Last time I piloted an M1A1 Abrams tank, great stress was placed on the oxygen-displacing effects of the halon fire suppression system. I would have the same concerns about a household halon system that I had in the Abrams. ex. You're in the most central part of your household and the halon system goes off. You're now [however] far from your front door and have what air you had in your lungs. Considerations for what might happen if it went off at night. Kids in the house? Hmmm..
for the tip on Carb media/plates. We use it as much as any other selection media, although it's more than twice as expensive.
Certainly, there are strains that are RecA pos, just as there are strains that express Tet and Cam resistance on their F' episome. I guess my point was more that there are such methods in place as to mitigate risk when working with engineered vectors. RecA is simply one layer of protection, and RecA- strains are used when it's needed.
As for curing a strain of a plasmid, I've never tried it directly, although you'll certainly lose your F' plasmid if you grow XL1-Blues without Tet.
I'm curious as to how you've accidently swallowed E. coli while doing lab work, though...multiple times? I can't think of a single time through all of the electroporations, ChemComp protocols, transformations, platings, yadda yadda that I ever got the pipette tip close to my mouth.;)
...to see the interface between engineers of two different fields. I would have expected to see more knee-jerk "OMFG" posts speaking about the supposed dangers of this, and it's refreshing to see that there's few. It's also nice to see a post get into the nitty of nucleotides, Watson-Crick base pairing and the base pair wobble rules.
For those concerned about unleashing a transgenic bacterium into the wild that could have horrible consequences, consider the following (wrt. academic research): The E. coli used in research labs are most often "recombinant deficient," and viruses are most often "replication deficient." What this essentially means for E. coli is that genes coding for proteins that integrate foreign DNA into the bacterium's genome have been "knocked out" by one method or another (gross mutation, removing significant chunks of promoter sequence and coding sequence, etc). Plasmids carrying the ampicillin resistance gene that are subsequently transfected into the bacteria confer ampicillin resistance to those that carry it, and even replicate to a high copy number within the individual bacteria, but the ampicillin resistance gene does not get integrated into the host genome. Unless the culture is grown in a media that has a constant selection pressure (ampicillin), the bacteria tend to lose their plasmid. Keep in mind that Amp is heat labile and generally has a short half-life at 37 degrees C.
Likewise, replication deficient virus vectors have certain necessary virus sequences (certain packaging genes, promotor sequences, and long terminal repeats), but they also lack the crucial coding sequences that would give them the ability to become harmful and fully replicative. Example: A lentivirus (a subset of the retrovirus) vector can be made to be self-inactivating once it integrates into the host's genome. Additionally, for a researcher to make virions, they must transfect the virus vector into a transgenic "packaging" mammalian cell line that produces the viral coat proteins. Once you have enough of a virus titer, you use these virions to infect other cell lines (which are minus the genes that code for the coat proteins).
In a lot of cases, removing any coding sequences for proteins that facilitate DNA recombination in a host makes this sort of research quite safe when carried out under Good Lab Practice(tm).
While scientists are generally held closely to the ideals of the scientific method by their peers, there are protocols for minimizing risk (using recombinant minus host organisms), and these must also be followed. No scientist wants to be known throughout the world as the one who unleashed the monster.
With respect to the original story poster's comment about "turning themselves off:" It may have caused some confusion. The action of a cell responding to a chemical presence is usually through an inducible promoter system. The presence of a chemical catalyzes the recruitment of transcription mechanisms to the necessary location so they transcribe mRNA that codes for whatever the response is. In this case (as in indicator), it's the enhanced green fluorescent protein (EGFP). If you remove the chemical, the transcription machinery isn't mobilized to the promoter, and ultimately, EGFP isn't produced. Quite elegant. Do some searches for the lac operon or the trp operon if one is curious.
To end this and tie back into engineers of 2 different fields, a molecular bio grad student around our lab often wears the "Code Poet" shirt from ThinkGeek. I tend to think it's as in context as in CE/CS, wouldn't you? DNA is code of the most ancient sort. After looking at lines of ATG GTC CCA CGT CAC... for a while, one could liken it to assembler.
We haven't figured out our compiler fully, though.
Cranky? Heh, heh. Perhaps. Perhaps I had also been in the organic lab quite a bit, in addition to studying for an AdvOrg test. The crankyness wasn't directed towards the submitter of the article, however. The submitter of the article was right on. They asked a rather interesting question, too. The misinformation jibe was most certainly directed towards those who answered incorrectly, making the "It's cyanide" connection and not bothering to back it up or do even the most basic of research behind the question.
As for the non-blue dye. That's entirely possible, which is why I included the alternative dye, phthalocyanine. It's non-blue. It still contains cyano groups.
Firstly, a cyano group is simply a carbon atom bonded to a nitrogen atom with a triple bond. In the term cyanide, the ide simply identifies the CN as an ion. Hydrogen cyanide (HCN) is the colorless, poisonous gas that may, or may not smell like almonds. (Go ahead...smell it.)
The blue dye you are thinking about is called cyanine, which is simply the common name for 1,1-diisoamyl-4,4-cyanine iodide.
If you go here, you will see a structure of cyanine. The only nitrogen present in the chemical is firmly rooted in a benzine ring (called pyridine). It's not going anywhere, and there's certainly no cyanide.
Additionally, the other dye used in CDRs is called phthalocyanine. Structure here. As you can see, the molecule is circular and the CN groups are in rings and in bonds between the ring structures. No hydrogen cyanide will be evolved.
While this doesn't answer why CDRs smell like almonds after/while they are being burned (do they? I've never smelled that), it does cast away some of the misperceptions.
OMG, yes! I remember this program. At the time (10yo, I think), I didn't even realize what AND and OR gates were, and I was using them to solve the problems.
I forgot to mention that it's point'n'click like QuickBasic is, so it's suitable for younger children.
Additionally, here's a link for game creation resources for those who are non-programmers. Since games keep interest up, this could be a way to teach programming.
Stagecast Creator is a fairly elementary language that can introduce the young ones to object oriented thinking. You can program multi-level games and applications like calculators. Each object is defined by its set of parameters and how it interacts with other objects. A few friends of mine have used it to introduce their kids to programming and have found it to be pretty successful.
On the whole, I agree with you. The abundance of anonymous places that offer wireless is rising. If I were hacking via wireless, I'd want to be in a public place, as it is less suspecious.
I wasn't arguing an analogy (ie. bulletproof glass, etc) or comparing computer crime to meat-space crime. I'm stating one of the reasons why I don't run a wide open web, and I think that the risks are legitimate, although not widespread. I trust most of my friends who use wireless, and they could have a node on my network anytime. On the other hand, I live in a university town. What does that have to do with anything? Our EE/CE/CS departments are pretty strong and have a long and proud history of pranks. Additionally, there are lots of kids with lots of free time.
While you may protect your data with your VPN, and it's nice to have a little drive-up internet access for your friends, I wouldn't say that personal data is my main concern, given those things are in place.
Think about what could be outgoing instead of incoming, and what that could mean to you, the owner of that IP address, and ultimately the responsible party for the traffic originating from it. Someone drives up, pauses for a little while, and:
1. Sends spam from your IP 2. Hacks something from your IP 3. Unleashes an IRC bot DDOS, with the command originating from your IP
The secret service follows up on every threat against the president, and if some spoofed e-mail stating that you thought it would be a good idea to do just that might equate to a visit from the black helicopters and men in sunglasses. Would you be able to say that you didn't send it? Perhaps....after they confiscate your computers and search through your hard drives and question your dog and kitchen sink...
Is it likely? Probably not, but considering that escaping the law is paramount to a h4x0r, wiping it off on Joe Luser via wireless would be pretty attractive. Sure, after it all gets straightened out and they let you out of Room 101, the only thing that may show up is that some unidentified MAC address popped up on your AP and sent it.
Come to think of it... now they may want to question your friends who use the AP to see if they own the card with the MAC address.
In all, I think an unsecured AP in the wild can open the owner of said AP up to some scary legal areas.
The recorder, sources told ABCNEWS, starts 10 minutes before Columbia's descent and measures the ship's temperature, aerodynamic pressure and other data. The information would not have been transmitted to NASA mission control during the flight.
Blackmail? I think you're thinking about extortion, but even that doesn't fit here.
From the dictionary...
Blackmail: Extortion of money or something else of value from a person by the threat of exposing a criminal act or discreditable information.
Extortion: Illegal use of one's official position or powers to obtain property, funds, or patronage.
The key word is illegal, and last I checked, it wasn't illegal to put stipulations on a donation. I could put any stipulations on a donation. ie. I'll give NASA 3 dollars, but only if they send me to the moon. NASA has every right to turn me down. There's nothing illegal in that. On the other hand, if they're so strapped for cash that I bought my moon ticket for 3 bucks, there's nothing illegal about that, either.
Sure, this could ignite a thread about [insert software vender of your choice] and their hole-filled software with respect to how fast service patches come out, but it's not meant to. It's about the reality of technology and the responsibility that goes along with it. You want the privilage of live internet? I think you need to know the basics of networking and security first, because it's a public forum and what you do has an impact on others. Don't want to step up? I've got an AOL CD with your name on it.
The security of my computer (and therefore, my bandwidth) is my responsibility. The physical security of my house is my responsibility. What about my car at the parking lot? Most places say they're not liable. So...I take the responsibility of making sure my doors are locked (and taking the risk of an actual glass-break-in) if I want to shop at [department store]. Being live on the internet isn't much different. You're still traversing among the public, only now the population is MUCH bigger. As soon as I stick my Cat5 in the wall, security IS my responsibility. I don't buy the stance of "it's Microsoft's fault my box is insecure, and there was no patch." We're all adults. You run what you choose on your equipment, and that's your decision. My ISP runs wide open, and they make it known that there isn't any filtering and firewalling going on. They like to deal with the computer savy customer and encourage the use of a non-windows machine for your firewall, and have free classes on how to set it up. If my WinNetOpenBeOSFreeBSDLinuxBox gets hacked and there's a patch or a config file that I neglected to update/change/whatever, isn't it my responsibility? I think so... You take your lumps, learn, and do better next time. The internet, like the circus, is a place where the smart get sifted from the ignorant, and usually the ignorant get parted with their money. Pay your nickel (ie. know your network), ride the ride...otherwise, you're in Soviet Russia....
After April 16th of this year, the HIPAA standards will go into effect for health care orginanizations. It's a set of guidelines that outline billing, among other things. One of the big issues is patient privacy. Take a look around. It's pretty interesting. Networks are required to be locked down, or the HCO is subject to an XX,000 fine for each patient privacy violation. (I think it's 35K, but I'm not sure.)
Implications:
802.11b? Hohahahaha. Nice try. Not until there's a better implementation. Backdoors? They're right out.
All of this is nice, in theory, and I'm sure that there will be HCO's that might try to cut corners, but this is an issue that is being pushed quite a bit with respect to the technical aspects of patient data storage and access. LET THE FINES BEGIN.
So far, 3 tech savvy docs have asked me to do a war-walk of their hospitals because they knew that they weren't going to pass muster come April, yet their administration (IT or otherwise) wasn't concerned. They simply wanted some proof that they could lay on the table, and I was one "of their techie friends." (yeah,yeah, perhaps a little risky) One was running their WiFi wide open (!!), and the other 2 were using WAP, but after an afternoon of sitting in a lobby, I got enough 'interesting' packets to yield the key. I hope it helped light a fire under someone who mattered.
Heh, this piece of equipment is pretty useful, thanks for the link. They've got a demo of their product in some 150Mhz machine running BSD that you can reboot. It took a while to connect, so I think curious/. readers have found their demo, too.;) Somewhere in a closet you can hear:
One can try looking at booq, also. They make a nice (albeit pricy) laptop/notebook backpack. It's the only one I could find that would fit my Sony GRX570 and its huge footprint. (the 16.1" screen is nice, though)
I hump one of these around on campus and have been pretty pleased with it. Our campus has started going wireless, so occasionally I'll pack my laptop and my 8dB omni and sit...where ever the heck I want. The antenna sticks out of the pack, so I look like an RTO.
That's so negligent it's not even funny. Kudos to your friend that patched their server, taking the security high road. Boo/Hiss to the guys who don't even pay enough attention to their own installation to know it's been tweaked.
...about the desk bursting into flames, people, and why all the "insightful" mods that go along with it?
