Our second day at Applebee called for the only rain forecasted the entire trip, and as a result most people chose this as a rest day. Not wanting to take a rest day, or be trapped in a storm we chose an objective that was not only close to camp, but also didn't involve any commitment (so as to facilitate an easy retreat), the west ridge of Crescent spire. Eventually in the mountains weather will occur, and you will have to face it. I'm not one to shy from unfavorable conditions; so we headed out prepared to get wet and turn back. In the least would be a good scouting day, and for me a good cloudage day for photos.
We had been carefully monitoring the sky on our approach, and without a doubt in my mind rain was coming. Still, that wasn't enough to make me skip great photo opportunities in the hopes of a pre-storm summit. This is a view of Snowpatch Spire from on top of Crescent glacier. On the right is the Bugaboo-Snowpatch Col with Pigeon Spire in the background. The Bugaboo-Snowpatch Col was apparently in the best condition out of the past several years, and the trail was well travelled. Still the low snow cover left lots of exposed loose rocks which tumbled down the col frequently. I'm glad to have had an experience getting up and down that obstacle under 'good' conditions before coming back in future years. As it was I found it a terrifying experience navigating around bergschrunds on such steep terrain (un-roped).
The Bugaboos - August 12-18, 2012
Living in Squamish I am very lucky to be surrounded by excellent rock to train my technical climbing skills as well as many great peaks for scrambling. But, until last week I had never had the opportunity to combine the two skills I've been developing for years. That all changed when a friend invited me to be her partner on the yearly trip my friend group takes. Two months after the invitiation, a partner swap, and a week of careful packing and preparation I actually found myself driving east about to embark on what would be the greatest adventure of my life to date.
The moment I arrived at basecamp my lofty climbing aspiration were downgraded to starting with a 4th class route and going from there. I received tons of advice from friends that had been going for several years, but still nothing could have prepared me for the reality of being there. The ascent to Applebee basecamp, the scale of the spires, the difficulty of the glaciers, and the exposure did not translate well to maps and photos I found myself in awe and terror. Every single obstacle I encountered was more physically and mentally demanding that I could have expected.
Even though we were with a large group of friends, we were on our own when we headed out for the day and often learning as we went. As a result we learned many lessons the hard way, including when to put crampons on, when to switch into rock shoes, how hard preventing rockfall can be, and all the ways rappelling can go wrong.
It was both the single most terrifying and rewarding experience of my life. Never did I expect to learn so much in a week, or do so little actual climbing. Instead it was a wild ride of alpine obstacles, and a truly life changing experience shared with great friends old and new.
A brief summary of my adventure:
Aug 12 - Hike into Applebee base camp with 80+lbs pack full of climbing, camping, and glacier gear as well as 7 days of food, and clothes for everything from -10 to +30 degrees celcius rain and shine.
Aug 13 - Eastpost spire, combination of Northeast and Northwest ridges.
Aug 14 - Crescent Spire, W ridge. - Rained off first attempt, after self arresting and improv. anchor construction.
Aug 15 - Crescent Spire, W ridge - Successful ascent followed by rappelling disaster involving ditching a rope that was later recovered
Aug 16 - Pigeon Spire, W ridge - Got 30m up route then turned back to save terror management skills for descent back down the Bugaboo-Snowpatch col
Aug 17 - Eastpost spire again and bathing in the tarn
Aug 18 - Hike out and long drive home
Please feel free to contact me with any questions regarding my experience.
Photos from this trip were taken with a combination of my Nikon D7000, Olympus uT8000 & GoPro HD2
My first quick (before going home from work) attempt at a transparent monitor picture. Colors are bad, the monitor background image is blurry and the monitor placement (or camera position) could be better. I'll make other attempts some other time.

I bought a 19" LCD monitor today so I could have more screen space when working at home. It fits nicely on my desk. This way I can do something like chat and work on an essay or coding without having to flip through windows.

Added some legs from ikea to my monitor stand. Before the shelf just rested on top of two box type things. It is much more secure now.
To show the use of the multimemory plugin in Munin to monitor easily memory leak. As this Perl services was processing around 5000 DNS answers per second, I finally figured out that the the issue was coming from a specific Perl module use (Date::Manip). That's another good reason to extend munin to match your needs.

Pixel e DPI - Definições:
Tecnicamente falando, um pixel é um conjunto formado por 03 micropontos de luz (01 vermelho, 01 verde e 01 azul), formando um triângulo. Cada conjunto desse é um pixel, o ponto de luz (ou ponto de cor) que "vemos" a olho nu no monitor. Quando falamos que uma imagem tem 800 x 600 pixels (largura x altura), por exemplo, significa que ela possui 800 pontos de luz vistos a olho nu em cada linha, e 600 pontos de luz vistos a olho nu em cada coluna. Nessa macro que tirei da tela de um monitor, se você ver a imagem no tamanho large - farm1.static.flickr.com/215/497800786_5e7fb1902b_b.jpg - dá pra ver esses micropontos vermelhos, verdes e azuis. Aliás, é por isso que os monitores trabalham com a paleta RGB (R = Red, G = Green, B = Blue).
Por isso que, quanto maior for a quantidade de pixels em uma imagem, mais detalhada a imagem fica - Quanto maior for a quantidade de pontos de luz definindo a imagem, mais detalhada ela fica.
Agora, outro fator que também é importante (se não o mais importante) na resolução são os "DPI" da imagem. DPI significa pixels por polegada (dot per inch) e vale a pena lembrar que, quanto maior for a quantidade de DPI de uma imagem, mais nítida ela fica. Uma imagem que tem 800 x 600 pixels pode, por exemplo, ter o tamanho de 28 x 21 cm, assim como também pode ter tamanho de 5,5 x 4,2 metros, ou qualquer outro tamanho físico. Agora, o que vai definir a nitidez (a resolução da imagem) é a quantidade de pixels por polegada. No caso de uma imagem que o tamanho de 800 x 600 pixels, no tamanho de 28 x 21 cm, ela será mais nítida do que no caso de a mesma imagem de 800 x 600 pixels no tamanho de 5,5 x 4,2 metros (vendo as duas imagens uma ao lado da outra). O porquê disso? Uma polegada equivale a 2,5 cm, então vamos fazer um pequeno cálculo no caso da imagem de 800 x 600 pixels no tamanho fisico de 28 x 21 cm ------- 28 cm/2,5 cm = 11,2 polegadas de largura, e vamos fazer o mesmo calculo com a altura --------- 21 cm/2,5cm = 8,4 polegadas. Então, 800 pixels/11,2 polegadas = 71 pixels por polega (71 DPI); e 600 pixels/8,4 = 71 pixels por polegada (71 DPI). Então, nessa imagem de 800 x 600 pixels, com tamanho fisico de 28 x 21 cm, vai nos dar uma resolução de 71 DPI, ou em outras palavras, uma quantidade de 71 pixels por polegada.
Se fizermos o mesmo cálculo para a imagem de 800 x 600 pixels, no tamanho físico de 5,5 x 4,2 metros, vai nos dar uma resolução de 4 DPI, ou seja, apenas 04 pixels por polegada.
Concluindo: 01 pixel significa 01 ponto de luz (ou de cor) visto a olho nu. Quanto maior a quantidade de pixels de uma imagem, mais detalhada ela fica, e quanto maior a quantidade de DPI, mais nítida ela fica.
Ufa! Depois de tanta palavra, espero ter esclarecido algo pra quem tem dúvidas quanto a isso...........

During the time the North Bloomfield Gravel Mining Company operated, as many as eight monitors were in use at the same time. Fashioned after Civil War cannons, the large monitors could weigh as much as 1 1/2 tons. The large monitors in the Diggins were capable of using 25 million gallons of water in a 24 hour period or over one million gallons an hour. The wooden box toward the rear of the monitor was loaded with rock to raise the barrel of the monitor and act as a counter balance created by the bucking water pressure leaving the nozzle.
The blasting power of a monitor or water cannon came from elevation drop alone. No mechanical devices were used. The water that came from a nearby resovoir exited in large pipes then graduated down in size until they reached the monitor and through a 10 inch nozzle. A large monitor would blast water at approximately 5,000 pounds per square inch, enough pressure to move a boulder the size of a small car. Different sizes of monitors had various functions. Large monitors were used to bring down the mountain, while small monitors were used to keep the debris moving down the sluice or long toms used to collect the gold and then on to the final exit point.
The miner that operated the monitor was known at the “piper.” He was paid the most for he had to know how to operate that big monster properly. If he didn’t, cave-ins occurred catching men unprepared thus causing injury and even death.
Legend has it that a miner with a dirty shovel set his tool into the stream of the water exiting from the cannon and the force of the water against the shovel moved the monitor’s aim with the greatest of ease and thus led to the invention of the ball and socket design we know today.
Monitors were made at the Joshua Hendy and the Parke and Lacy Company in San Francisco. Also monitors and hydraulic equipment were made locally in the Nevada City Foundry. The Malakoff mine pit on the San Juan Ridge is a testimony to the avarice that was part of the California gold rush, and to one of the nation's first environmental protection measures.
In 1850 there was little gold left in streams. Miners began to discover gold in old riverbeds and on mountainsides high above the streams. In 1851, three miners headed northeast of what is now Nevada City for a less crowded area to prospect. One miner went back to town with a pocket full of gold nuggets for supplies and was followed back by many prospectors. These followers, however, did not find any gold and declared the area "Humbug", thus the stream was so named "Humbug Creek". Around 1852, settlers began to arrive in the area and the town of "Humbug" sprang up. These miners could not decide how to move the dirt to a place where there was water.
By 1853 miners invented a new method of mining called hydraulic mining. Dams were built high in the mountains. The water traveled from the reservoirs through a wooden canal called a flume that was up to forty-five miles long. The water ran swiftly to the canvas hoses and nozzles called monitors waiting in the old river beds. The miners would aim the monitors at the hillsides to wash the gravel into huge sluices. Over time the monitors became bigger and more powerful. Their force was so great they could toss a fifty pound rock like a cannonball or even kill a person. Over 300 Chinese worked on this project and two Chinese settlements existed in North Bloomfield (Humbug).
In the late 1860s, the towns of Marysville and Yuba City were buried under 25 feet of mud and rock, and Sacramento flooded repeatedly. The farmers in the valleys complained about the tailings that flooded their land and ruined their crops. Thousands of acres of rich farmland and property were destroyed as a result of hydraulic mining.
By 1876, the mine was in full operation with 7 giant water cannons working around the clock. The town had grown to a population of around 2000 with various business and daily stage service.
In 1880, electric lights were installed in the mine and the world’s first long distance telephone line was developed to service the mine, passing through North Bloomfield as it made its way from French Corral to Bowman Lake.
By 1883, San Francisco Bay was estimated to be filling with silt at a rate of one foot per year. Debris, silt, and millions of gallons of water used daily by the mine caused extensive flooding, prompting Sacramento valley farmers to file the lawsuit Woodruff v. North Bloomfield Mining and Gravel Company. On January 7, 1884 Judge Lorenzo Sawyer declared hydraulic mining illegal.

That is the main part of my monitor hanger. The whole thing sort of looks like an old (US) football goalpost. The monitor hangs from a crosswise 2 x 4, narrow side up. The main assembly of the monitor hang looks like an upside down T. A narrow round aluminum tube sticks straight up from a crosswise square aluminum tube. That lower juncture uses some very large washers and HDPE plastic for lubrication, and allows the square crosswise part to pivot/rotate. At both ends of that crosswise aluminum tube, the 26 inch LCD monitor hangs from thin nylon ropes (new lightweight monitor design helps greatly with this setup). Hanging the monitor on ropes allows it to tilt forwards and backwards to any angle.
If you are thinking "What's the big deal?"...
Look up to where the vertical aluminum tube connects to the crosswise 2 x 4. The part that holds the tube to the 2 x 4 is barely visible. It is a single piece of 1/8 inch thick aluminum flat bar, about 1 1/2 inches wide by about 6 inches long. That is all it is, a piece of aluminum, but it functions like a complex device. It is bent in half at slightly less than 90°. It has a large hole on one side (hidden from view) where the round aluminum tube slides through it. So all you do is stick the aluminum tube through the hole in that single piece of aluminum flat bar, and hang it on the crosswise 2 x 4. No fasteners are required. The monitor can be raised with a single hand, and lowered with two. Thanks to that extremely efficient device, both the vertical and horizontal positions on the 2 x 4 are infinitely adjustable. Leverage at the hole where the tube goes through the flat bar keeps the tube from sliding downwards (aluminum sticks to aluminum). That same force keeps the tube snug against the 2 x 4 so that the monitor does not sway.
That point is also usable for swiveling the monitor, if it were needed.
Still don't get it? Oh well. Beauty is in the eye of the beholder. Because it's not complex, it might seem insignificant. It's the most efficient device I have ever made, or ever even seen (except for something like a wheel).
On one side of the goalpost is a desk with a chair. The uprights include small jutting shelves to hold various stuff. In between the uprights is a bed. Right now I am sitting at the desk, later when playing Supreme Commander 2 for hours I will be lying down. Cordless keyboard and mouse are very useful.
Edit:
Three and a half years later it still works perfectly. Maintenance free.
This is a better look at the junction, raising the monitor with one hand.
Un monitor és un tipus de vaixell cuirassat amb grans canons en comparació amb la seva mida, i destinat al bombardeig de la costa. Aquest és un sopervivent de la Primera Guerra Mondial, on serví als Dardanels.

A monitor is a warship specialized in shore bombardement, with its heavy guns. This one served in WWI, mainly in the Dardaneles campaign.
There are many options available allowing patients with diabetes to monitor and manage their glucose levels. The Continuous Glucose Monitor (CGM) shown here includes a glucose level sensor and transmitter, a data receiver which displays the patient's glucose levels, and an insulin delivery system (pump), which administers doses of insulin decided by the patient and their health care provider. Patients should always make insulin and other diabetes dosing decisions using a blood glucose level result. Insulin may be delivered by pill, syringe, pen, or pump.
