8. Blood, Sweat, and Urine

Q. Ethan McCallum O'Reilly Media ePub

I spent six years working in the statistical modeling team at the UKs Health and Safety Laboratory.[23] A large part of my job was working with the laboratorys chemists, looking at occupational exposure to various nasty substances to see if an industry was adhering to safe limits. The laboratory gets sent tens of thousands of blood and urine samples each year (and sometimes more exotic fluids like sweat or saliva), and has its own team of occupational hygienists who visit companies and collect yet more samples.

The sample collection process is known as biological monitoring. This is because when the occupational hygienists get home and their partners ask How was your day?, Ive been biological monitoring, darling is more respectable to say than I spent all day getting welders to wee into a vial.

In 2010, I was lucky enough to be given a job swap with James, one of the chemists. Jamess parlour trick is that, after running many thousands of samples, he can tell the level of creatinine[24] in someones urine with uncanny accuracy, just by looking at it. This skill was only revealed to me after wed spent an hour playing guess the creatinine level and James had suggested that we make it more interesting. Id lost two packets of fig rolls before I twigged that I was onto a loser.[25]

1.29. Ruby Documentation

Michael Fitzgerald O'Reilly Media ePub

Ruby documentation refers to the documentation generated by RDoc (, a program that extracts documentation from Ruby source files, both from C and Ruby files.

The documentation is stored in comments in the source files and encoded so that RDoc can easily find it. RDoc can generate output as HTML, XML, ri (Ruby information), or Windows help (chm) files.

To see the RDoc-generated HTML documentation for Ruby, go to If you have Ruby documentation installed on your system, which you likely do if you followed the installation instructions earlier in the book, you can type something like the following at a shell prompt to get formatted documentation in return. Type:

and you will get this output:

Here are the RDOC formatting basics:

Paragraphs in comments become paragraphs in the documentation.

Words preceded by equals signs (such as === Example) will be headings in the result, varying in font size depending on the number of equals signsthe more you use, the smaller the font of the heading. One = for a level-one heading, two == for a level two, and so forth.

CHAPTER EIGHT. Dream architecture: signs and symbols

Marcus West Karnac Books ePub

One of the hardest things for people new to interpreting dreams is to begin to make sense of the wealth of dream images and to orientate themselves within the dream. In my experience, and that of many others, there are certain dream images which commonly symbolize certain kinds of thing (they are archetypal). I offer these as starting points for understanding the dream image, although an individual’s personal associations to the image will usually have more significance and should be considered to take priority, even if the general, archetypal meanings might also apply.

Symbols and signs

To explore this caveat a bit further, one must be wary of immediately equating a dream image with a particular meaning, for example, horse equals body. Jung was critical of Freud in this respect. He thought that Freud interpreted symbols, which Jung thought had many layers of meaning, as signs that point to just one thing. For example, he accused Freud of interpreting anything pointed: a church steeple, a cigar, a pencil, a sword, a walking stick, etc., as a penis; and any container: a handbag, a box, a coffin, a purse, a cul-de-sac, etc., as a vagina. As Jung put it, “You can say that a church spire is a phallic symbol but when you dream of a penis, what is that?” (Jung, 1957, p. 305, quoted in Colman, 2005, p. 641).

Blair Howard Hunter Publishing ePub

There are four main shopping areas in Bermuda: the City of Hamilton,  St. George's, SomersetVillageand the Royal Naval Dockyard. Most of them have been covered in the section on sightseeing. Despite the small size of the island, you won't be disapointed by the high number of sophisticated, multi-story department stores, specialty shops, gift stores, jewelry outlets and perfumeries on the main streets and waterfronts of all four areas, not to mention the hidden shops tucked away all around the islands.

Service in retail stores is, for the most part, helpful and courteous. Sometimes, however, the pressures of the tourist industry will overcome even the most patient of service personnel, who tire toward the end of the day and whose tempers can become a little ragged. This doesn't happen often, but if it does, just smile and pass right along. There's always another store just down the road.

The best bargains in Bermuda are goods imported from Europe. Such items as Italian, German, English and French knitwear can often be purchased at prices far below those in the United States. Watches (Rolex, Omega, Patek Philippe), jewelry, French perfumes, Icelandic woolen goods, and fine china can be 50% cheaper than at home.

17. Monitoring Multivendor Networks

James Sonderegger O'Reilly Media ePub

Assuming you havent skipped too many chapters, if you have made it this far into the book you have learned how to transition routing, switching, Multiprotocol Label Switching (MPLS), and the related signaling protocols from a single-vendor to a multivendor environment without risking the availability of the network. A major part of the transition is retaining the ability to monitor the performance and stability of the network. The primary purpose of network monitoring is to protect the availability of the network from hardware failure, configuration error, unauthorized access or activity, and performance degradationin short, making sure the network is capable of providing performance and services as designed.

This chapter describes configuration elements and gives tips to support classic monitoring and management of fault, configuration, accounting, performance, and security (FCAPS) in a network with high availability requirements. The chapter describes both JUNOS and IOS configuration elements pertaining to Simple Network Management Protocol (SNMP), system logging, remote access, and simple traffic monitoring in relation to their ability to support high availability.
