This is good science. In 1924 we didn’t have any strong reasons to think that there wasn’t intelligent life on Mars. If anything, the evidence seemed to favor the other direction. Moreover, simply having ships listen in wouldn’t have cost that much money. So this was an experiment with potentially very high pay-off compared to the resources it took.

They discovered that an ice sample containing pyrimidine exposed to ultraviolet radiation under space-like conditions produces this essential ingredient of life. ‘We have demonstrated for the first time that we can make uracil, a component of RNA, non-biologically in a laboratory under conditions found in space,’ said Michel Nuevo, research scientist at NASA’s Ames Research Center, Moffett Field, Calif. ‘We are showing that these laboratory processes, which simulate occurrences in outer space, can make a fundamental building block used by living organisms on Earth.’”

Possible Interpretations… - by interactive_civilian (Score: 5, Insightful) Thread

I have a feeling that this will lead to the speculation that Earth was therefore seeded with fundamental biomolecules from space and this paved the way for life to begin on Earth. I hope people don’t jump to this conclusion too quickly. Personally, I find it unlikely and think there is a more likely interpretation, which I will get to in a moment. The reason this is unlikely is that just having biomolecules is not enough to start life processes. Especially in the time frame when life is hypothesized to have originated (~3.8Gya), as the surface of the Earth was completely covered by ocean at that time, and any seeding of organic molecules from external sources runs into the concentration problem: the problem of getting enough of the right molecules in the right place with the right concentration and the right inputs of energy and raw materials for biochemistry to begin. Any such seeding from external sources would end up very dilute, and biomolecules would likely break down before they could be gathered in sufficient concentrations.

Personally, one possible interpretation which I prefer is that these findings (and similar ones of finding amino acids in comets and such) indicate that organic biomolecules are fairly common and will form anywhere you have C, O, H, N, S, etc and energy. Not only would this indicate that biomolecules could form fairly easily on Earth, but that they are common in the universe, and organic life may arise just about anywhere you have an input of energy and raw materials and a way of concentrating those molecules so they will react and form self-organizing and self-replicating biochemistry.

My current favorite hypothesis about the origins of life on Earth are those championed by Martin and Russell. They hypothesize that life on Earth began and alkaline hydrothermal vents in the ocean, around which porous rocks of iron and nickel sulfide would form semi-permeable cell-like compartments in which basic organic molecules formed by the geochemistry of the vent could concentrate and react with each other. Raw materials would be constantly input from the vent, and there would be a constant energy gradient in the form of heat, pH, and proton-motive force. This neatly solves several problems of many hypotheses of abiogenesis: the energy problems, the raw materials problem, and the concentration problem to name a few. They outline the overall picture of going from geochemistry to biochemistry to prokaryotes to eukaryotes in this 2003 paper:

On the origins of cells: a hypothesis for the evolutionary transitions from abiotic geochemistry to chemoautotrophic prokaryotes, and from prokaryotes to nucleated cells - Martin and Russell, Phil. Trans. R. Soc. Lond. B 29 January 2003 vol. 358 no. 1429 59-85

They further clarify the possible pathways for a shift from geochemistry to biochemistry in this 2006 paper:

On the origin of biochemistry at an alkaline hydrothermal vent - Martin and Russell, Phil. Trans. R. Soc. B 29 October 2007 vol. 362 no. 1486 1887-1926

A search for either of those followed by clicking on the “Cited By” link on Google Scholar will yield many papers, including some actual experiments supporting them, which expand and clarify these hypotheses. Definitely worth a read if you are interested in the possible origins of life on Earth, as well as perhaps some ideas of what to look for when looking for life elsewhere.

Anyway, point being, this is fantastic work by NASA, and an excellent example of showing that these molecules can form naturally. Just be careful about drawing any definite conclusions from them other than the simple conclusion that Uracil can form in these natural conditions, and possibly or probably others.

They would “report” the current events and either mail, telegraph, telex or eventually send the “story” in through radio or a satellite TV link. All of this cost money, and news companies had to sell a lot of advertising to cover costs.

But guess what? Times have changed. Now anyone with a cell phone and internet access can provide “breaking news”. How often do I see CNN or other “news” channels showing the EXACT same video that was on LiveLeak.

- Begin with the history of the building, when it was built (1995), why it was build (result of Andrew in 1992), and how it is constructed (twin T, poured tilt wall).

Infastructure: 
- Take you through the gen room, show you it is internal to the building, show you the roofing structure from the inside, explain the N+1 redundancy, the hours on the gens, when they are ready for maintenance, how they are maintained, by whom (the vendor), how the diesel is stored, supplied, duration of fuel at max and current loads. Explain conduct before a hurricane or lockdown, how we go off grid 24hours ahead of a storm, mention our various contracts for after storm refill and our straining / refill schedule. 
- Take you to the switch gear room, explain the dual feeds from the power company, how the switch gear works, show you the three main bus breakers, show you the numerous other breakers for various sub panels, etc. Explain and show you the spare breakers we have in case replacement is needed. 
- Take you to the cooling tower area, explain the piping, the amount of water flowing, the number of pumps, how many are needed, the switching schedule, explain the N+1 capacity and overall capability of the towers, explain maintenance, show you the replacement pumps in stock, explain the concept of condensed water cooling if needed. 
- Take you through the UPS and battery rooms, explain the needed KW capacity, what the UPSs back up and what they do not. Show the various distribution breakers out to floor, their capacity, the static switches, bypass, explain the battery capacity, type of cells, number of cells, number of strings, last time the jars were replaced and how they are maintained. Explain max capacity of the load vs time. Answer questions relevant to switching from utility->UPS->generator and back.

Raised floor: 
- Take walk on raised floor, explain connectivity, vendors, path diversity we have, how the circuits are protected. Show them network gear, dual everything, how we protect from a LAN or WAN outage, and specific network devices we have for DDoS, Load Balancing, Distribution, Aggregation. Explain how telco and others deliver DS0 to OC-12 capacity, offer information on cross connections regarding copper, fiber, coax. Explain our offerings (dedicated servers up to 5K sq ft cages) and ask what they are interested in. 
- Explain below the floor, size of raise, that power and network is delivered under, what are on level one trays, level two trays, and the piping for cooling. Show the PDU units and how they related to the breakers in the previous rooms. Show them the cooling panel and leads out to CRAC units, explain the cooling capacity, plans for future cooling, explain hot/cold aisle fundamentals, and temperature goals. At this point, there are usually more questions about vented tiles, power types available and overall floor density in watts/sq ft. 
- Explain the fire detection / mitigation system, monitoring of PDU’s, CRAC units, and FM200. Explain the maintenance of the fire system, show them the fire marshal inspection logs and the panels that alert the police and fire departments (both on floor and in our security office in front). 
- While finishing the walk on the floor, show cameras, explain process to bring in and remove equipment, tell them the retention on the video, explain the rounds the guards make, the access list updates and changes.

NOC: 
- At this point we’re back to the front of the building, go into the NOC, explain what we are monitoring (connectivity, weather, scheduled jobs, etc). Introduce NOC and security staff, explain they will always get a person if they call, submit a test ticket from a e-mail on my phone, they will see the alerts light up and the pager for the NOC will signal. The final steps are to introduce them to security and then I’ll lead the customer(s) to the conference room so they can continue the conversation with the sales associate.

The sales person is normally with us. During the tour we will explain our SAS certifications and disclose any other NDA information. I see two types of tours, the first is the discovery tour, which is when a company or government entity is on a fact finding mission to see if we are close to their needs, then they talk with the SA. The other type (more common) are the tours taken after the agreement has been worked out and this is the final “sales” procedure. Our facility really sells itself. Once on tour, most sign up (if they are serious) within 24 hours. I probably missed a few things, so if you want me to follow up I can. For me, everything I present are things the customer NEEDS to know before installing in my building.

- Power quality: never seen a big datacenter without a Liebert, or at least UPS in every rack. Power does not have the be contitioned except between the UPS and the machines/devices. A whole data center power conditioner is often more efficient, but unnecessary for the little guys. either way - check. 
- Age is irrelevent as long as it’s under support. If it’s not, replace it. Generators need to be run several times a year to validate their condition, and also to grease the innards… See too many good generators get kicked on and fail an hour later because the oil hand’t been changed in 3 years… 
- Outages should be tracked, by system, rack row, and power distro. When system seem to be going down more frequently in one area, there’s usually an underlying reason… As Google recently proved as well for us all, do not ASSUME all is well, routine disgnostics including memory scans should be performed on ALL hardware. Even ECC RAM deteriorates with age (rapidly) and needs to be part of a maintenance testing and replacement policy - Check. 
- Fire suppression is usually part of your building codes, and a given, as is the routine checks (at least anually) by law.

In addition, we deploy: 
- Man traps on all enterences to data centers. You go in one door, it closes, then you authenticate to a second door. A pressure plate ensures only one person goes in/out at a time (and it it’s tripped, a scurity guy looking at a screen has to override). 
- Full 24x7 video surveilance of the data centers. 
- in/out logs for all equipment. To take a device in/out of a datacenter requires it being logged in a book (by a designated person). This is for anything the size of a disk/tape and larger. All drive bays are audited nightly by security and if drives go missing, security reviews the access logs and server room security footage to see who might have taken them. 
- clear and consistent labeling systems for rack, shelves, cables and systems. 
- pre-cable just about everything to row level redundant switches, and have no cabling from server to other servers not passed through a rack/row switch first. Row switches connect to distro switches. This ensures cabling is simple, and predictable. 
- Colorcoded cabling: we use 1 color for redundant cabling (indicating their should be 2 of these connected to the server at all times, and to seperate cards in the backplane and seperate switches to boot), a seperate color for generic gigabit connections, another color for DS View, another color the out management network(s), another color for heartbeat cables, and yet another for non-ethernet (T1/PRI/etc). Other colors are used in some areas to designate 100m connections, special connectivity, or security enclave barriers, and non-fiber switch-to-switch connections. Every cable is labled at both ends and every 6-8 feet inbetween. 
- FULLY REDUNDANT POWER. It’s not enough to have clean poewr, and good UPS and a generator. In a large datacenter (more than a few rows, or anything truly mission critical), you should have 2 seperate power companies, 2 seperate generators, and 2 fully segregated power systems at the datcenter, room, row, and rack levels. in each datacenter we use 2 Liebert mains, each row has a seperate distribution unit connected to a differnt main, and each rack has 4 PDUs (2 to each distro). Every server is connected to 2 seperat PDUs, run all the way back to 2 completely independent power grids. For a deployment of 50 servers or so this is big time overkill. We have over 3500 servers, we need this… We can not rely on a PSU failure taking out racks at a time which may server dozens of other systems each.

Oracle is a big Eclipse supporter too - OEPE - by jambay (Score: 5, Interesting) Thread
Disclaimer - I work for Oracle and came from the BEA Systems acquisition.

My personal opinion is that Oracle is very dedicated to the entire Eclipse ecosystem as well as to JDeveloper. It’s about choice. There is an entire free download product that is continually being enhanced called the Oracle Enterprise Pack for Eclipse (Oh-Pee is how we say it within Oracle). In fact I believe it was one of the first, if not the first commercial IDE to support the latest Eclipse 3.5 Galileo. http://www.oracle.com/technology/products/enterprise-pack-for-eclipse/index.html OEPE is targeted for Java and JEE developers and is mostly about supporting the Java standards. Additionally, the majority of the TopLink code was donated as the EclipseLink project and is currently the JPA reference implementation. Just take a look at the presence has at the next Eclipse conference and I think you will see that Oracle is committed to Eclipse. http://www.eclipse.org/eclipselink/

When you get into the “upper-stack” components like SOA Suite for integration and WebCenter Suite for enterprise portal development, and Oracle’s Application Development Framework (ADF) that Oracle strongly recommends JDeveloper. Those products have been based on JDeveloper for a long time and the user-experience developing for those products is extremely smooth because Oracle can influence everything about the IDE. If you want to do Java and JEE development in JDeveloper, you can do that too. It’s your choice.

Unfortunately for Netbeans zealots, it has never caught up with Eclipse. It may have surpassed it temporarily for certain apps (think Grails support - but look at STS 2.2.0). It’s also not as good as IntelliJ IDEA (previously, always non-free).

Yes, both Netbeans and Eclipse are also RCP platforms, but how many real Netbeans platform apps are there? (The Nokia one on the web site is vapourware - yes it shows a real customer RAN - without their permission, I should add! - but it’s never been a product delivered to customers). Real Eclipse RCP apps do exist (XMind, Lotus Smartsuite…). Realistically, they both over good RCP platforms (one pure Java, one SWT) but Oracle won’t really care about that.

As for JDeveloper - well it’s a typical Oracle product - if you’re in an Oracle house, it’s pretty good, but no, it’s not got a large userbase or community supporting it.

Oracle should let Netbeans drift off into open source land. Perhaps it’ll thrive? I don’t know. JDeveloper’s functionality should be ported to Eclipse (along with SQL Developer, while we’re at it).

There are two things that I like it better than Eclipse: 
- it’s 100% Java and runs fine on anything that has a JVM (Eclipse’s SWT has platform specific dependencies which prevented me from using it on 64bit machines, it took ages for it to have proper x64 support) 
- better developer experience because of a cleaner and sensibly chosen set of plug-ins that all work out-of-the-box with no dependency hell (Eclipse plug-ins is a mess unless you pay for commercially packaged versions like MyEclipse)

Noise graph of Researchers Neutralize Parkinson’s Dopamine Killers Researchers Neutralize Parkinson’s Dopamine Killers - by ScuttleMonkey (47% noise) View Skip
futurity.org writes with news that Iowa State researchers have made a breakthrough that could eventually lead to a cure for Parkinson’s. Identifying the protein that kills the dopamine-producing cells in the brain has allowed the researchers to disable it and could be the first step in the development of new treatments. “Now, Kanthasamy’s group is looking for additional compounds that also can serve to neutralize protein kinase-C. By identifying more compounds that perform the function of neutralizing kinase-C, researchers are more likely to locate one that works well and has few side effects. This discovery is expected to provide new treatment options to stop the progression of the disease or even cure it. ‘Once we find the compound, we need to make sure it’s safe. If everything goes well, it could take about 10 years, and then we might be able to see something that will truly make a difference in the lives of people with this disorder,’ says Kanthasamy.”

Re:Skepticism may be warranted, here. - by reverseengineer (Score: 4, Informative) Thread
“Protein kinase C” is really at least 10 different proteins in humans- “isozymes” that have similar function, but different structures and different regulation mechanisms. All of the protein kinaseC variant belong to the larger class of serine/threonine kinases (about 100 different enzymes), and all the work that any of those enzymes do is to add a phosphate group to a serine or threonine amino acid on a protein. That role is important because protein phosphorylation is used as a molecular switch to activate or deactivate a protein. There’s nothing special about this particular protein kinase-C isozyme, other than the target it phosphorylates.  
 
Presumably, the target of this particular kinase C form is involved in the apoptosis pathway for dopamine-releasing neurons, so keeping the molecular switch from being turned on could prevent the cell death from being carried out. Since the structures of isozymes are different, you could develop a drug that knocks out this variant of PKC without turning off PKC globally.  
 
However, preventing apoptosis of neurons, while possibly leading to an effective treatment, still does not address why brain cells would feel the need to kill themselves. For instance, in at least some Parkinson’s patients, neurons suffer from a buildup of improperly folded protein called alpha-synuclein (compare amyloid and tau in Alzheimer’s, prions in prion diseases). (However, overall there are many possible causes of Parkinson’s and related syndromes, including unknown causes.) Cell suicide is meant as a protective measure for the remaining cells so they are not in turn poisoned by the output of misfolded proteins. What happens when you turn off apoptosis, and cells which turn “sick” are no longer able to die?

First of all, there isn’t just one Protein Kinase C. There are a number of different versions with different jobs. Hence the list of the various isozymes in the article. The one in question is Protein Kinase C delta (PKC), and is NOT covered in the wikipedia article. 
 
PKC mediates apoptosis, or programmed cell death, in certain dopamine producing neurons. By blocking the enzyme, you can prevent the apoptosis. Reading some of Dr. Kanthasamy’s papers, it’s clear that he’s already found some agents that do this in animal models. This is, of course, a long way from human trials (10 years if things go well, I believe is what he said in the article). But this is very promising avenue of research. 
 
What I can’t figure out is why this is recent news. Dr. Kanthasamy has clearly been following this line of research for a few years. There’s a 2007 paper entitled Neuroprotective Effect of Protein Kinase C{delta} Inhibitor Rottlerin in Cell Culture and Animal Models of Parkinson’s Disease, so clearly he had already connected PKC with PD and was already investigating agents to block it.

Noise graph of The Big Questions The Big Questions - by samzenpus (61% noise) View Skip
Frequent Slashdot contributor Bennett Haselton changes things up today by reviewing The Big Questions: Tackling the Problems of Philosophy with Ideas from Mathematics, Economics and Physics. Questions that big need a big review and you can learn what Bennett has to say about it all by reading below.

The first thing that I have to admit as a reviewer is that I enjoyed the book — not just reading it, but scribbling out pages of scratch paper working on the puzzles inspired by the book — that I probably would have paid up to about $200 for it (despite the fact that I disagreed with many of the conclusions, and even thought some of the arguments were pretty weak). I certainly don’t mean that it’s better than books by Richard Dawkins, Daniel Dennett, Steven Pinker, Malcolm Gladwell, or Steven Levitt and Steven Dubner (the Freakonomics and SuperFreakonomics team), but it will appeal to many of the same people.  
 
Those authors’ books typically marshall a large amount of research data and evidence in support of a thesis that seems contrarian but turns out to be probably true. The Big Questions (released November 3rd with a companion website and blog doesn’t do that. The book is divided into many self-contained vignettes and side topics and independent arguments, which are based more on logic and reasoning than externally gathered evidence, and the arguments don’t always convince you of the conclusions. But that’s part of the fun: many of the arguments in the book are structured so rigorously, almost like mathematical proofs, that if you disagree the conclusion, the challenge is to figure out why you think the conclusion is wrong. (Nobody ever scribbled equations in the margins of Malcolm Gladwell’s books trying to figure out if he was “right”.)  
 
You’ll probably enjoy the book the most if the following are true for you:

  • You enjoyed math all the way through high school, especially the paradoxes that seemed to grow out of elementary rules of logic or probability. Sometimes the paradoxes resulted from a flaw in one of the reasoning steps, so that identifying the flaw led to a deeper understanding of how to conduct those steps. And sometimes there really is no flaw in the reasoning, so that the conclusion, no matter how counterintuitive, must be true.
  • Eventually, though, you ran out of “paradoxes” that could be described in the language of intermediate mathematics. There are other paradoxes lurking in mathematics, of course (like the celebrated Banach-Tarski paradox), but most of them require you to learn so much mathematics just to understand the paradox, that there aren’t enough hours in the day.
  • So, you’d be delighted to discover paradoxes in an entirely new field, where arguments built from elementary rules of logic, lead to a conclusion that seems at first to make no sense, but leads to a deeper understanding the more you think about it.

The core philosophy of The Big Questions — not embodying any of the conclusions, but rather the rules of the game by which those conclusions should be reached — is expressed in two lines near the end:

If you’re objecting to a logical argument, try asking yourself exactly which line in that argument you’re objecting to. If you can’t identify the locus of your disagreement, you’re probably just blathering.

Many of his arguments read like he started off with the intention of writing somethingn entertainingly contrarian and counter-intuitive, then assembled an argument to defend it. And, of course, a book author has the advantage of only taking on arguments that he himself allows in the book, gets to decide which factors of the problem are relevant, and so on.

I did pass the test the reviewer offers here: I had specific points at which I disagreed with his argument. But I didn’t find that fun; it’s no fun halting all agreement with an argument at step 4 and having to go on and read steps 5-9 while holding a little asterisk in your head that says “none of this matters because 4 is clearly wrong”.

As an example, the heart of his “more sex is safer sex” argument used in the title is that overall risk is reduced if *certain* *people*, those with lower odds of having disease, have more sex. Then the people they have sex with are having safer sex than if with someone else. Alas, it rests on the contention that if the “safer” people have more sex, every act *displaces* another sexual interaction - the possibility that simply more sex will occur, the added interactions being safer, but *not* displacing a less-safe one, is not allowed for. Recommending that certain prudent people have more sex, while assuming that the amount of total sex in the world will remain a constant, is not, to my mind, a safe assumption. But it wasn’t slashdot; all I could do was sit there, frustrated at my inability to argue with the book.

So I’ll give this one a miss. Thanks anyway.

Free will ain’t no argument against time travel! - by Dr. Manhattan (Score: 4, Interesting) Thread

Basically you have a situation where there is a physics question (are CTCs possible, and if so, how would they work?), where one of the strongest arguments available is based on the assumption of free will (the feeling that older-me can *choose* freely to warn younger-me away from the CTC).

From my own far-too-long-and-obsessive meditation on time travel:

A lot of people don’t like this model because it would seem to eliminate any possibility of free will. Personally, I don’t particularly worry about whether I have free will or not. If I do have free will, then I don’t have to worry about it. If I don’t, then there’s no point in worrying about it. Either way…

But this model doesn’t necessarily pose problems for free will. Consider normal ideas about time and free will. Your parents freely chose to have you, right? At the very least, their free choices led them to the point where they did have you, though hopefully they were happy about it.

Now, assuming no time travel, those choices cannot now be changed, right? They cannot now decide not to have had you. The moment of choice was back then, somewhere in the past. Once that choice was made, it was fixed. Assuming free will, it was not totally determined by what led up to it in some physical deterministic sense, but once made it could not be changed. This is not a constraint on free will.

Now, just by adding in time travel we needn’t change anything about this. Choices are freely made at the moment they are decided. It’s just that now it’s possible to know what those free choices “were” at a point in time “before” the choice “will be” made. (English again forces us to use strange tenses to speak about this. Oh, well.) Remember, in this model, there is no privileged point we can pick out and call ‘the present’. Every moment is past to some instants, future to others. Every moment is a “present”.

(Note that some people use this idea to reconcile the idea of God knowing what we will do with the notion of free will. God, existing outside of time, doesn’t ordain what people do, It just sees them doing it. I only bring it up to point out that lots of people have no problem in principle with the idea that they both have free will and yet someone knows with certainty what they will do. I don’t see why it’s any different if someone besides a God has that knowledge…)

If you see a movie of yourself from the future doing certain things tomorrow, from a certain perspective it doesn’t mean that you are “fated” to do those things. It just means that you know, when that time comes around, that doing those things will seem to you to be the best available choice.

Perhaps the future choice seems silly, or even terrible. Well, can’t you think of a moment where you’ve made a choice, and then later (perhaps only a second later) thought, “What was I thinking?” The fact that it seems unlikely to you that you will make that choice doesn’t mean that you won’t make it. People do things they never expected to do, even said they wouldn’t do, all the time.

Seriously though - I know many major religions are of the gnostic type… hvae to have higher knowledge, enlightened, etc. But what exactly does “beyond discussion” mean? Not doubting/convinced? It seems that not-being-in-doubt and being-convinced are feelings reserved for atheists, now. Only someone dogmatically believing in the non-existence of an entity are allowed to be sure of their belief. Which is odd, since most logicians will tell you that it is much harder to prove non-existence than it is to prove existence. I wonder why Landsburg didn’t mention that? Seems like that is a “big question” - why are many logicians and scientists atheists, since they are so careful not to deny existence of other things that we don’t even have evidence for; they simply understand that denying existence is a big logical step in that you have to disprove every possible existence first. When it comes to the supernatural/God though, they are quite willing to believe in a non-existence and not be open to discussion. Why does Landsburg only pick on those who are convinced, perhaps illogically, that God does exist?

Incidentally, you can be illogically convinced to believe an correct thing, and you can be logically convinced to believe an incorrect thing. Logic is an argument; what you logically deduce or induce from makes a big difference, as your premise may be wrong, thus your conclusion could be wrong as well.

virtually no one behaves as if they actually believe in everlasting damnation after death as punishment for sin.

Most people don’t behave like there is death at all. Most people don’t want to talk about death, don’t want to hear about death, and don’t even want to think about death. Many people “defy” death and live like they won’t die. I guess that means death doesn’t actually exist! Cool!

I’d wondered before about how many people really did believe in God, but in just a few pages this argument had me thinking that the number was a lot lower than I’d ever thought before.

So without seeing any numbers and going entirely on the basis of logical deductions from unproved and perhaps disputed premises, you are coming to new conclusions on what people actually believe - without asking them.

In addition, this same idea could be used in the US and other locations to beam 10 MWs into disaster locations. The ability to bring in say 1 MW into multiple locations within 1 hour would make a HUGE difference in say hurricane, earthquake, or even another 9/11.

Now maybe if they converted the solar to hydrogen first, and then used that to fuel spaceships to colonize Mars and other planets, it might make sense.

What I do … - by Grayputer (Score: 5, Informative) Thread

Alrighty, I AM a CTO of a 20 person company with a single admin and here is what I’m interested in.

1 - problems and their resolution

2 - potential issues

3 - time sinks.

So I get info on: 
What broke last week and how did we fix it: a list of hardware software outages, their root causes, the fix applied, whether that fix is a long term of short term fix, if short term, a recommendation for a long term solution

Issues that my admin sees as ‘near term’ problems (2 months): list of systems low on resources (disk, cpu, ram, …), applications that have repeat issues, upgrades that are due and are non trivial (potential downtime, critical app where the ‘upgrade gone wrong’ may lead to down time, …), etc. This includes a list of any planned downtime and a description of the planned downtime (including ‘the plan’/timetable of events) so I can remind or co-ordinate with others.

Issues that my admin sees as ‘mid term’ problems (12 months): list of systems due for replacement, applications/OSes that are near end of life, need for additional hardware (network switches, firewall upgrades, …), etc

Any single issue that he spent more than an hour on or anything he is repeatedly spending time on, those are my definition of time sink.

Why am I interested in those specific items: 
    Items in category 1 are apt to come up in conversation with my boss. They are also items I need to monitor to ensure that the systems, applications, and yes the admin staff, are not causing the company headaches.

Items in categories 2 and 3 fall into planning and budget issues that I need to plan for, or co-ordinate with others.

Category 3 also allows me to eventually understand that application A or staff member B or ‘department’ C are killing us and I need to find a better way for the company to work. It also allows me a better understanding of whether the week is an anomaly or if I need additional admin staff or training.

None of this is in a rigid format, so no I can’t forward you a template :). It is currently done via office visits/conversations, emails, and hallway conversations. That is working and I see no need for a more rigid structure unless we start to have communications issues. When we do, I’ll setup a more formal status reporting system (currently, if it ain’t broke …).

Bottom line, in a small company, single admin case where that admin reports to the CTO, the CTO is effectively the systems/IT manager as well as the development manager, the CTO or corporate level planner, and the executive level consultant/evangelist on IT matters to the CEO and CFO. I do NOT necessarily expect the admin to be an IT manager, being an admin is frequently hard enough. However, that ‘department’ is not my only concern so to some extent the admin needs to summarize stuff and not ship me logs/raw data, I have too many hats.

I’ve worked in large and small companies, and the one unifying truth of executive communication is that they do not want details. In their mind, they hired you to take care of the details, If you say you need $100,000 to increase bandwidth at remote locations, you had better have a one or two sentence explanation about how this is going to make them money or help them make money. If they want to see a utilization chart or two, have that ready, but you’re going to be tuned out if you launch into a long explanation.

I’m not an MBA, but my guess would be that they teach MBAs to focus on strategy and leadership, and to hire people to do the nuts-and-bolts work. Same goes for small business owners, but double — they’re doing crazy 120 hour weeks growing the business - why would they want to listen to a report from the guy they hired to make sure they wouldn’t have to deal with “all that IT stuff?”

As long as you keep that in mind, reports to executives will go well. Short, simple, money- or productivity-focused explanations, very little technical information, etc. Think like they are thinking — “Why am I paying for this?” “How does this make me money or keep me from losing money?”

I started working at an organization a while back and I would file a trouble ticket whenever I came across something broken, even if it was unimportant and with an overflowing workload might not be done for a while. A manager was hired after a while who decided to use the trouble ticket system as a meter of progress for tasks done. When he announced this, I immediately closed all of these types of tickets, saved them locally on my machine, and even went into the database so as to delete all vestiges of these tickets. I began only creating tickets when I knew a task would probably be done on-time and quickly. The manager was canned after about two years there - the thing that saved him for so long is that his manager changed three times while he was there, the third one axed him.

What management wants to see is that their investment in you is getting results. If they spend X amount of dollars on something, they want to see how it is helping the company or whatever. Show how successful your projects have been, how your uptime rate is always increasing etc. Use lots of colorful charts, lists with 20 goals and “accomplished” next to 18 of them and “partially accomplished” next to the other two. That type of crap. I mean, if management wants this nonsense from the sysadmin, you’re in Dilbert land already.

After 13 years in this industry, I’m becoming convinced that the dumb, pointless things management makes you do does have some strange psychological point along these lines. I’ve quit agreeing with my co-workers that these presentations are dumb and pointless, I think they do have a point - keeping us disciplined, from requesting sane hours and on-call rotation and all of that.


Noise graph of Verizon Droid Tethering Comes At a Hefty Price Verizon Droid Tethering Comes At a Hefty Price - by timothy (89% noise) View Skip
Pickens writes “Tom Bradley reports in PC World that the new Motorola Droid smartphone will cost users $199.99 with a 2-year contract, with an additional $30 per month for the mandatory ‘unlimited’ data plan that has a monthly cap of 5Gb. Verizon will charge $50 for each additional gigabyte over the 5Gb limit on the unlimited data plan. Verizon has confirmed that tethering will cost another $30 per month for an additional unlimited data plan that is also limited to 5Gb. If you want tethering you will pay $60 above and beyond the monthly contract for service for an ‘unlimited’ 10Gb of data per month, and if you plan on connecting with an Microsoft Exchange email account you have to pay another $15 a month. ‘Verizon seems to be doing everything it can to make the Droid as unappealing as possible by nickel and diming customers so that actually using it is not cost-effective,’ writes Bradley. ‘After all of the hype around Verizon’s marketing efforts, and generally favorable reviews of the Motorola Droid, users that rush out to get the new device may be in for a shock.’ Droid users will have to wait until sometime in 2010 for tethering. ‘That service is on our schedule for next year,’ says Verizon spokeswoman Brenda Raney. The delay is because ‘the service has to be tested on the phone so until we know it works, we don’t offer the service. It is not uncommon for us to introduce the phone and continue to test the service and offer it later.’”

PC World Has it out for the Droid - by limaxray (Score: 5, Informative) Thread
I’m convinced PC World has it out for the Droid and has only been carrying negative articles about it. This article is particularly misleading. First of all, the unlimited phone data plan IS unlimited - it’s the tethering, WAN card, Mifi, etc plans that are limited to 5GB a month. Just head over to the Verizon website and check out the fine print. Now the catch is if they think you’re tethering without a tether plan (which is really easy to do) they’ll charge you for tethering. So if you use 10GB a month of phone data (which, lets be honest here, is not realistic using just your phone) they’ll hit you for tethering. 
 
Next, the $15 a month for Exchange is if you’re an enterprise customer. I’m not really sure what that means - if they host the account for you, or handle some extra securtity stuff, or what - but if you’re just average Joe user with your own personal account, you won’t need to pay it. There is no problem using Exchange with the regular personal data plan. 
 
These facts can easily be confirmed by checking out Verizon’s website, but the boys over at PCWorld are too busy making out with their iPhones to do any fact checking.

This crap has been circling the web and it’s not completely accurate. With the $30 and $45 data plans for smartphones, you get unlimited data for the phone itself. If you want to tether, it’s an additional $30 for the $30 plan or $15 for the $45 plan and will allow you 5GB of tethered data and unlimited on the phone. In any case, if you want to tether and be within their TOS, you need to pay $60. It’s still possible to tether without the extra cost and their software, it’s just not within their TOS  
 
The difference between the $30 and $45 data plan isn’t documented well and leads to a lot of confusion. I fault VZW for not getting this strait. All the $45 gets you is access their WirelessSync service and supposedly allow you to do Exchange ActiveSync within the TOS. The $30 plan CAN DO Exchange ActiveSync, but it’s supposedly not ok within their poorly documented TOS and every VZW employee will tell you that you need the $45 plan if you’re going to do Exchange ActiveSync.  
 
If you do use a lot of data on your phone, VZW can cancel your data account according to their TOS. I’ve used >5GB/month without a peep from VZW and any additional charge on my bill. It has been said in HoFo, if the data usage is extreme by VZW opionion, they could consider that your must be doing something that’s violating the TOS. If VZW was smart, they wouldn’t do much canceling since they’re launching a bunch of Android phones and saying streaming YouTube and music is ok, which obviously will soak up a lot of bandwidth.  
 
I suggest that Pickens and the article author do some fact checking before publishing assumptions and hearsay.

All of this would be fixed by a very simple law - anybody ought to be able to set a limit on their monthly bill. If I call up evilphoneco and tell them that my cell phone bill is capped at $90 per month, then I don’t care WHAT services I consume - they can’t charge me more than $90 per month. It is their job to keep me from using services I haven’t paid for - not my job to avoid accidentally incurring them. And no incurring of debts either - if they deliver me $10k worth of services they can bill me $90 once and then we’re even.

Oh, the second part of that law would be that everybody’s cap starts out at whatever their basic monthly rate is. Unless somebody specifically requests a higher limit they couldn’t be charged for any “optional” services.

And no giving people limited choices like $10/month or unlimited only. People should be able to name their own limits as arbitrarily as they’d like.

It seems like phone companies depend on people making $500 mistakes with their cell phones, and they almost count on people doing it. They get zero mercy when it happens. At best they might be offered an option for $10 per month to cap their bill. That should NOT be something that costs money.

Seriously. Far too many fat people basically think that their life is on hold until they lose weight. “Once I get skinny, everything’s gonna change.” This is, of course, fucked.  
 
I’ve been fat pretty much my whole life (currently 260 on a 5’11’’ frame). I (quite truthfully) eat a pretty sane diet, rarely drink (maybe a beer or two a week), don’t smoke and get moderate exercise (biking, walking, etc.) (And I don’t own a game console, or a car for that matter.) I probably could be thinner if I hit the gym for an hour or two and stuck to a 1800 calorie diet every day for the next 50-100 years. But I’d rather just live my life, thanks. 
 
This isn’t to say I haven’t tried in the past. Not too long ago for about a year and a half I used to bike commute (10 miles each way) and hit the nearby gym for some additional workout (I needed the gym to shower anyway.) I did lose some weight during that time but nothing dramatic - I was still a fat guy. But I bike-commuted mainly because it was fun, not just to lose weight. When my company changed offices bike commuting was no longer practical, so I also stopped hitting the gym. I still get my biking in on the weekends, because biking’s still fun. 
 
My advice if you’re fat - and it took me far to long to accept this myself - is to go live your life. Get out of the house. Have fun. Meet people. Be adventurous. Hang out. volunteer. Buy good-looking clothes that fit well. Go dancing. Go to the beach. If anyone snickers at you doing something that’s considered strictly at thin-person activity, just say “Fuck ‘em if they can’t take a joke.” and keep going. If you’re fat and doing all this already, more power to you. 
 
And since this is one of the main objectives with weight loss: If you’re single, go out on dates. Again, seriously. Fat people date, have sex, fall in love, etc. etc. all the time. Heterosexually speaking, there are plenty of women who don’t mind if a guy’s big. There are even plenty who like big guys. And there are certainly plenty of guys who like or don’t mind big women (Raises hand!) You can look online, natch, but don’t be afraid to give someone you like the eye. Ask them out. If you get the brush off or get shot down, well it happens to skinny people too. And remember that nothing is sadder than a fat person who hates others for being fat. Karma can be a bitch. 
 
If you’re looking to get exercise and eat better, go for it. But don’t let an image of a skinny you dominate your life. Be one of those many people out there living long, happy, loving, fulfilled lives. Who also happen to be fat.

Finally he shows how fat has been wrongfully vilified over the past 50 years, and so if you take fat (high-density energy storage) out of the diet, it is replaced with carbs, and that itself is what triggers the storage system.

In practice, many studies have been done, and none have shown notably higher weight loss from low card diets than from low fat diets.

Because my job is IT, I’m sedentary for long periods of time, and as such, will accumulate fat, especially given that in my mid-30’s I still eat just like I did in my mid-teens.

Due to my particular personality - mild OCD, extremely impatient - I am very, very good at modifying the way I look in short periods of time. I lost 19 pounds in a week, just to prove a point. I ate 3 hard boiled eggs per day, 1 slice of whole wheat toast, lots of water, lots of coffee, and never stopped chewing sugarfree gum. I also exercised for 4-5 hours per day. It takes incredible willpower. It absolutely sucks. You’ll feel like shit. But it does work.

Swimmers who cross the English Channel and Florida Straits also lose huge amounts of weight in very short periods of time. Susie Maroney lost 22 pounds in just over a day when she swam from Cuba to Key West. Not all of it fat, to be sure, but a lot of it was.

Much hype was made about Michael Phelps’ diet when he trains. He consumes between 10,000 - 12,000 calories per day while training. So imagine your daily food intake, and quadruple it. That’s how much he eats. And that’s just to prevent him from losing weight. He has to eat that much to stay the same.

I also freedive. Freedivers are some of the leanest athletes in the world. They tend to stay away from gyms as too much muscle burns too much oxygen. The repeated depletion and replenishment of O2 across the cell membrane really burns the calories. After a 4-day freediving training session off the coast of Florida, I had lost 6 pounds of fat in 4 days.

As others have noted, most people feel like they’re doing a lot of exercise, but they simply aren’t.

This post is extremely misleading and dangerous. Why anyone would want to propagate this lie is beyond me.

Exercise does lead to weight loss. The article cited clearly says it does. It’s just that a small amount of exercise — aerobic exercise for short periods over a mere three months, without strength training or diet changes — is less effective than you’d want it to be. Well duh. But even in those circumstances, with all those factors stacked against weight loss, the participants still lost some weight.

A counterexample: A mildly overweight or average person, who has no heart problems and is otherwise healthy, can engage in much more vigorous exercise. An hour on the elliptical can burn approximately 700 calories. An hour in an intense gym routine can burn more (ever see those ads for LA Boxing touting the one-hour 1000 calorie workout?). Lets say you do an hour of 700-calorie cardio every morning and dont change your diet. That’s an additional 3500 calories you’re burning per workweek. If you give yourself weekends off and don’t change your diet and don’t strength train, you’re still losing a pound a week, mostly of fat. If you add in proper diet — not calorie restriction per se but just switching from soda to water or cutting out one or two greasy meals a week — you’re doing better. Add in strength training and you’re be doing amazingly.

But it’s not enough to just diet. The health benefits of good cardiovascular health and muscle strength are important in their own right. Things like the Hacker’s Diet work to lose weight, but they are very unhealthy, even possibly dangerous. It condones a quantitative instead qualitative approach; the Hacker’s Diet seems to take the position that you can eat microwave pizzas for every meal as long as you keep it under about 2000 calories. What it doesn’t tell you is that in the process you’ll be failing to provide muscular support for an aging skeletal system, adding cholesterol to your body, hardening your arteries, and atrophying major muscles.
