So these are my notes on setting up Nagios 1.2 on Mac OS X Server 10.3.5. If nothing else, it'll add to the Google Database. Nagios, for those unfamiliar with it, is an open source network monitoring application, ala Intermapper, or Lansurveyor. (Although if you don't know what Nagios is to begin with, you're going to want to check out the Nagios site before you do all the work I talk about here.) Note, this is not with MySQL support compiled in, since that's going away in favor of an n-tier structure. There are a few requirements for Nagios, namely zlib, libpng, libjpeg, and GD lib. if you have current versions of them already, you're golden. otherwise, follow the appropriate steps (If you're installing this on a stock Server setup, you don't have them). You also need Apple's Developer Tools, otherwise you have nothing to compile with. All of this is from my experience installing this on a G4 Tower running Server 10.3.5 and now into the breach...
Nagios is great. Here's how to set it up on OS X, instead of the typical Linux. bynkii.com's Network Notes: October 2004 Archives |

This page is intended to give somebody interested in GEF most of the things he has to know to get started. This includes a description of the purpose of the library, a global view of the library with descriptions of the different components and how to use them, and some practical guidelines to build a simple GEF editor. At least that's what I have tried to do. I wrote most of this for myself a few months ago but I think this is better here than on my personal hard drive. Maybe it could be useful to you.

Wondering what your pre-money valuation will be if a VC ever puts a term sheet on the table? Valuing a startup is intrinsically different from valuing established companies. Because of the high level of risk and often little or no revenues, traditional quantitative valuation methods like P/E comparables or discounting free cash flows are of little use. Startup valuations are largely determined based on qualitative attributes. We've been told by several investors that our valuation model produces reasonably good valuations. Of course, every situation is different, so your mileage may vary. Answer the following 25 questions, and we'll calculate an approximate range for you. For each of the following questions, choose the answer that most closely describes your situation. If you don't know the answer, select the first choice.

That's it. That's all we're looking for. Memorize that. Recite it to yourself before you go to bed every night. Our goal is to hire people with aptitude, not a particular skill set. Any skill set that people can bring to the job will be technologically obsolete in a couple of years, anyway, so it's better to hire people that are going to be able to learn any new technology rather than people who happen to know SQL programming right this minute.

Samar is a very radical community. One of the stories that circulates around the Kibbutz Movement about them is the story of their common purse. They used to have cash freely available in a basket in the dining room, whoever needed any could go and help themselves. This wasn't actually denied, but I saw no evidence of this basket when we had lunch together there. However, they do set their own budgets, both of money and of labor days, and the different members differing needs are respected and catered for. They are not strong on committee work, preferring to give themselves an anarchic freedom to do the things that seem best to each one. And they keep themselves solvent, generating a profit each year to invest in projects of various kinds. On the way down to the dairy farm Brian showed me some solar powered glow lights, enough to mark the path on moonless nights.

Judicial Watch released this Defense Intelligence Agency (DIA) Intelligence Information Report (IIR), declassified and released to Judicial Watch on October 30, 2004, in response to a Freedom of Information Act (FOIA) open records request filed by Judicial Watch in January 2000, concerning the decision of the Clinton administration to bomb the al Shifa pharmaceutical factory in Sudan, and suspected al Qaeda terrorist training camps in the vicinity of Khost, Afghanistan on August 20, 1998. The dual-site bombing operation was codenamed ȁCInfinite Reach.ȁD The bombing was reportedly in retaliation for the August 7, 1998 bombings of US embassies in Kenya and Tanzania. The DIA is derived from handwritten documents obtained through a classified intelligence project with the unclassified nickname ȁCSwift Knight.ȁD According to the report, the documents were written during the first two weeks of October 1998. The spellings, references and phrases in the report are verbatim transcriptions from the original handwritten document (e.g. Osama bin Laden [OBL] is referred to as ȁCUsam ben LadenȁD). The IIR provides basic biographical information concerning bin Laden and traces key points in his public, militant activities, resulting in the formation of al Qaeda. The IIR includes language from the document that describes how al Qaeda envisions achieving their goals, including ȁCethnic cleansingȁD and ȁCcontrol over nuclear and biological weapons.ȁD An additional reference is made to ȁClatent penetration,ȁD a reference to so-called ȁCsleeper cells.ȁD A good deal of information concerning bin Ladenȁ9s and al Qaedaȁ9s efforts in Chechnya, the Caucasus, Crimea, and the Central Asian Republics is covered in the IIR.

Sensors placed in the borehole could detect changes in strain, tilt and pressure in the ground miles below the surface. "That will be a great advantage in giving us a few days or hours warning before something happens. Current warning systems in Japan only warn us 10 minutes before a large earthquake strikes. We need real-time data from the exact point."

On a larger scale, such as a continent surrounded by oceans, heat build up on land over time will result in lower density air masses, or areas of low pressure. Conversely, denser air associated with high pressure dominates ocean surfaces. Wind and ocean currents that result from air flowing from high to low pressure mix areas of warmer and colder air and water, contributing to the global energy balance. This exchange is evident at different levels of the atmosphere. Air converging into a low pressure center at the surface rises, leading to moisture condensation and the subsequent release of heat into the upper atmosphere. Diverging air at the surface in a high pressure center is associated with subsiding air from the upper atmosphere and evaporation, a mechanism for energy storage. Just as energy imbalances develop between land and water surfaces, the variation in space and time of solar heating due to the earth's tilt create seasonal hemispheric energy imbalances. The hemisphere receiving the most direct radiation (during the summer months) experiences a net radiative heating (more energy is gained from the sun than is lost to space). The winter hemisphere is at the same time experiencing net radiative cooling. As part of a global compensation, heat is transported from warmer to cooler areas by ocean and wind currents. Since the areas of heat surplus and deficit change throughout the year, as in the sea breeze example, the direction of transport must change as well. Figure 3 shows low latitude surface wind directions averaged over the summer and winter seasons. As noted earlier, climates dominated by monsoons experience the most pronounced seasonal wind shifts, indicative of a pronounced land-sea effect. In the South Asian example, the rainy season, typically beginning in June, is preceded by nearly two months of scorching temperatures, cooled only with the commencement of the summer rains brought by the southwesterlies. January is the peak of the dry season, which is marked by cool, dry northeasterly flow over most of the region.
