If you’re living in America, Thanksgiving’s a pretty big deal.  Everyone’s got a to-do list that’s got eating, traveling and a bit of cooking on it.  These snapshots encompass all of the above, intersecting at color, layout and theory. This farmers market spread showcases autumn’s rustic spectrum and is sorted by food and color. Following a similar path, this Scion xB advertisement taps autumn’s palette revealing a basic grid for display.  The tag line for this youth-oriented Toyota reads, Same Shape. Different Boxes, reminding us how we live our lives, sorting information as we go. Whether you’re a passenger or a driver this holiday season, you’ll undoubtedly find yourself scanning and sorting, be it food, family or football.

penghemat listrik

Salah satu cara untuk membebaskan diri dari tagihan energi besar serta peroleh dari mereka akhirnya adalah dengan mengaitkan rumah Anda untuk off grid listrik. Ini adalah akses yang Anda gunakan untuk menciptakan energi Anda sendiri dan kemudian pasangkan ke perusahaan listrik utama. Kelebihan kekuatan yang Anda hasilkan disalurkan ke konsumen lainnya sehingga penghemat listrik dapat menggunakannya juga.

Off grid listrik yang digunakan lebih mahal sepuluh tahun yang lalu dan sarana untuk dapat menghasilkan energi Anda sendiri akan sangat sulit untuk dipasang. Saat ini Anda akan melihat banyak tetangga Alat Hemat Listrik dan teman-teman Anda karena mereka sendiri dari aplikasi listrik jaringan di rumah mereka.

Ada beberapa manfaat yang bisa Anda dapatkan dari grid listrik dari setup selain memiliki sistem cadangan jika listrik Anda conks keluar. Seperti dijelaskan dengan melewati produksi kelebihan Penghemat Daya Listrik kekuasaan ini dibayarkan kembali kepada Anda oleh perusahaan listrik setempat. Tidak hanya akan Anda akan memperoleh sesuatu dari itu di beberapa negara beberapa pemerintah daerah memberikan kredit pajak untuk Penghemat Energi Listrik orang-orang yang mengembangkan sendiri energi bersih serta bentuk-bentuk lain dari subsidi untuk biaya pembangunan.

Merakit sistem seperti ini juga tidak terlalu sulit. Anda tidak perlu menjadi seorang insinyur Penghemat Energi Listrik atau ilmuwan roket untuk meletakkan satu bersama-sama. Ada banyak sumber di Internet yang akan mengajarkan Anda di mana untuk membeli bahan-bahan serta memberikan rencana pembangunan tentang cara untuk membangun satu. Anda hanya Hemat Energi Listrik akan perlu pengetahuan dasar tentang penggunaan alat-alat umum dan anda sudah siap untuk pergi. Bahkan remaja yang telah menaruh beberapa kit ini bersama-sama oleh mereka sendiri tanpa bantuan dari orang dewasa. Sejauh ketersediaan suku cadang dan komponen banyak situs sekarang menawarkan untuk mengirimkannya pintu ke pintu atau bahkan lokal Anda lakukan-it-yourself toko harus membawa mereka sudah.

Untuk panel surya kit sistem seperti ini bisa biaya rendah dan itu sudah termasuk US untuk para Hemat Energi Listrik amp dummies amp guide.

Tentu saja jika Anda hanya ingin mengambil mudah dan memiliki beberapa profesional melakukannya Anda bisa. Ini akan menjadi sedikit lebih mahal tapi cara apapun yang Anda pilih Anda akan tetap mendapatkan untuk menyelamatkan banyak dalam jangka panjang dan akan mudah untuk menghitung biaya yang telah dikeluarkan.

Fitur bagus lain tentang memasang panel surya Alat Hemat Listrik array adalah bahwa mereka dapat modular dalam arti bahwa Hemat Listrik Pln Anda dapat partisi mereka Hemat Listrik Pln ke Hemat Listrik daerah-daerah tertentu dari rumah anda atau untuk sejumlah peralatan saja. Penghemat Daya Listrik Anda tidak harus membangun semuanya dalam Alat Penghemat Listrik satu pergi. Yang anda perlu lakukan adalah menghitung konsumsi peralatan Anda yang menjalankan non-stop dan yang Anda gunakan dari waktu ke waktu. Setelah memberikan tunjangan ke beban maka Anda akan tahu berapa banyak kekuatan yang Anda akan perlu penghemat listrik untuk menghasilkan listrik jaringan dari setup.

I always have to hunt down the snippet in some other project, of which I can never remember which, to do this. So, as I said in my intro post – This is where I store snippets of code to do things.

checked=’<%# Eval(“Required”).ToString().ToLower().Equals(“true”)?Convert.ToBoolean(“True”):Convert.ToBoolean(“False”) %>’

To bind a boolean value requires a small trick. I’ve seen other methods of doing this, I just find this one to be the most elegant and adaptable.

I usually write at the end of the week. Usually saying how the week has gone. Usually feeling pretty weary. With today off though, I feel a lot happier!  The mocks are coming up in two weeks, and I prepared for them today – just making revision sheets with all I need to know on them. I have the feeling I will do really well in them, and (the big-headed part of me says) the teachers will be begging me to do their subjects on parents evening in January. Let’s hope! Hehe.

At grid (my youth club) tonight, we were talking about the computers we have blown up. Emily was saying the other day how her screen was playing up. So she hit it! Then she got more violent… until finally this big cloud of smoke poured out the top. “There was this awful smell as well” she said. Frazzled electronics never smell good. She explained the trouble she got into. Then it reminded me of when I was younger, and I just turned on the computer and this evil mushroom cloud of smoke came out of it. It was like an atomic bomb. And it smelt dreadful too.

Those evil smells were rather as evil as Katherine’s hiding behind the door. She was standing there, and as Emily walked into the chillout-room she jumped out on her, giving her a nasty shock! Tonight was hillarious!

Continuing our seven-part blog mini-series entitled “7 Things You Need to Know About Oracle 11gR2″, Integra Senior DBA Jason Buchanan, recently one of just twelve people from around the world hand-picked by Oracle to participate in the Oracle 11gR2 final beta, offers his thoughts on the CRS to Grid transition in Oracle 11gR2:

Oracle 11g Release 2 provides a streamlined upgrade solution for the database and supportive products such as CRS and ASM. It’s important to take into consideration some of the changes in 11.2, specifically the location of where CRS and ASM binaries are located.

For the most part, upgrading the database and database binaries is much the same as upgrading previous releases – but CRS is different.

CRS isn’t really CRS anymore, either. It is now the Oracle Grid Infrastructure which is comprised of CRS and ASM, rolled into a single Oracle home. An existing CRS installation is upgraded by creating and installing to a new Grid Infrastructure home. From a migration/upgrade perspective this implies the requirement of approximately 4GB of storage for the Grid Infrastructure home. The old CRS home can eventually be archived or deleted.

The CRS to Grid upgrade procedure is streamlined and relatively worry-free – I have done this dozens of times this year and have not experienced upgrade problems except for problems that were pre-existing misconfigurations by the client. Network issues such as incorrect subnet masks, static routes, MTU size mismatch, etc. are usually caused by improper setup and not an Oracle software problem.

Ideally, the best upgrade method from 11.1 to 11.2 is in the form of a migration rather than an in-place upgrade. This is the quickest path to upgrading not only the database but the hardware, storage and OS, and a means to clean out Oracle homes with several patch levels applied.

Please check back soon for Jason’s next entry in this blog series: “Top 5 Tips for Reducing TCO with Oracle 11gR2″.

As always, I’d love to hear your thoughts and comments here, or on our Facebook discussion board!

Thanks!

{Colors for a Large Wall (1951)}

There are an increasing number of virtual worlds, in addition to Second Life, that offer virtual experiences to educators and students. I stopped by Heritage Key the other day to view their King Tut’s Tomb exhibit, and brought back the photos below. HK is still in its alpha version and doesn’t run quite as smoothly as Second Life yet, but it will catch up. You do need to create an account and download a viewer, which uses Second Life technology, so the viewer and the navigation in HK will be familiar to SL avatars. Currently, HK is much like a virtual museum, and a good one, but I hope it evolves to offer more creative experiences for the average user. In the meantime, enjoy the photos. They were accompanied by professional audio narrations of the meaning of the wall drawings, adding to the value of the experience.

The name of the piece and the square it moves to – and a few other easy to learn rules including x = takes, + = check, 0-0 castle King side, and so on. The tedium comes in having to “learn” the grid which comes about by noting many games, right? What about learning to “think” and “speak” the grid, keeping the mind focused on the physical space referred to by a grid address, and saving the mental and physical energy required to see the piece, then look off to the side and edge of the board to figure out where it is? Once the grid is learned, writing it down becomes merely an excercise in discipline.

Open Source Software (under development) can be used to quickly learn the grid much like the addition/subtraction math facts and multiplication tables. (see http://www.chibcha.com/kids/index.html )
Used in conjuction with a SANCS chess board concentration can then focus on learning the game.

If you thought you might not see another green energy or less-dirty energy exchange traded-fund, there is a new ETF for you.  First Trust Advisors is launching the First Trust NASDAQ Clean Edge Smart Grid Infrastructure Index Fund of the First Trust NASDAQ Clean Edge Smart Grid Infrastructure Index Fund (NASDAQ: GRID) today.  So far we are seeing a gain in the ETF by 0.8% to $30.39, but on fairly thin trading volume of about 134,000 shares as of 11:20 AM EST.  We have seen many other green ETFs, but this is actually the first designated ETF or ETN that is geared solely toward the smart-grid rather than just to green energy.  There will be some overlaps in this ETF with others, but that is often the case.

This ETF aims to track equity index called the NASDAQ OMX Clean Edge Smart Grid Infrastructure Index, which is designed to act as a “transparent and liquid benchmark” for the grid and energy infrastructure sector.  The most interesting aspect of this is that it may highlight which individual companies are making leaps and bounds here in the smart grid.  As you might expect, there are many overlaps in here with the other clean or green ETF products via the PowerShares Global Clean Energy (NYSE: PBD), PowerShares Cleantech (NYSE: PZD), PowerShares WilderHill Clean Energy (NYSE: PBW), and the First Trust NASDAQ Clean Edge Green Energy (NASDAQ: QCLN).

The Index is a modified-market cap weighted index and includes companies that are “primarily engaged and involved in electric grid, electric meters and devices, networks, energy storage and management, and industry-related software.”  The index is also jointly owned by the NASDAQ OMX Group,
Inc. (NASDAQ: NDAQ) and Clean Edge, Inc.

There are many overlaps in here as you might expect with electric and clean/green ETF products already on the market.  We have listed notes here on each if they are in the top ten components of other ETFs such as PowerShares Global Clean Energy (NYSE: PBD), PowerShares Cleantech (NYSE: PZD), PowerShares WilderHill Clean Energy (NYSE: PBW), and the First Trust NASDAQ Clean Edge Green Energy (NASDAQ: QCLN).

Some of the components are as follows (and noted if they are in top ten holdings in other clean or green ETFs):

• Advanced Energy Industries (NASDAQ: AEIS)
• American Superconductor (NASDAQ: AMSC) (also in PBW, PBD)
• Comverge Inc. (NASDAQ: COMV)
• Digi International Inc. (NASDAQ: DGII)
• Echelon Corp. (NASDAQ: ELON) (also in PBW)
• EnerNoc Inc. (NASDAQ: ENOC)
• ESCO Technologies Inc. (NYSE: ESE)
• General Cable (NYSE: BGC)
• General Electric Co. (NYSE: GE)
• Intellon Corp. (NASDAQ: ITLN)
• ITC Holdings Corp (NYSE: ITC)
• Itron Inc. (NASDAQ: ITRI) (also in PBW and QCLN)
• Mastec Inc (NYSE: MTZ)
• Pike Electric Corp. (NYSE: PIKE)
• Power-One Inc. (NASDAQ: PWER)
• Quanta Services Inc. (NYSE: PWR)
• Satcon Technology Corp. (NASDAQ: SATC)
• Valmont Industries Inc. (NYSE: VMI)
• WESCO International Inc. (NYSE: WCC)

The larger ADRs listed in the index are as follows:

• ABB Ltd. (NYSE: ABB) ADR (also in PZD)
• Cooper Industries Plc (NYSE: CBE) ADR
• Jinpan Intl Ltd. (NYSE: JST) ADR
• National Grid PLC (NYSE: NGG) ADR
• Siemens AG (NYSE: SI) ADR (also in PZD)
• Telvent GIT SA (NASDAQ: TLVT) ADR

In order to keep companies like GE from being the entire weighting, there is a methodology used to keep the weighting down or in-check.  These have to have smart-grid exposure and traded on an eligible stock exchange.  Pure-play components are given a collective 80% weighting, and the more diversified components not deemed pure-plays are given a 20% total weighting.  The pure-play components must derive 50% or more of revenues from smart grid, electric infrastructure, and other grid related activities.  Companies with a market cap of under $100 million are not eligible and the average daily share trading volume must have averaged $500,000 per day.

What is important to look at is the disclosures and risks associated with all ETF and ETN products so you know exactly what you are investing in…

There is a tracking-risk here which the release noted as “NON-CORRELATION RISK” where the ETF’s return may not match the return of the Index for a number of reasons: operating expenses for the fund not applicable to the index itself, and costs in buying and selling securities.  The ETF will generally not sell a stock because the stock’s issuer is in financial trouble, unless that stock is removed or is anticipated to be removed from the index.  The ETF will also invest in securities of non-U.S. issuers, which can be subject to additional matters of U.S.-traded stocks; and that also brings in a currency risk into play as the Net Asset Value is determined on the basis of U.S. dollars each day.

A NEGATIVE NUCLEAR POWER STORY

Well here it is.

Adentrarse en los secretos de la materia y conocer el momento previo a la creación del universo constituye el principal objetivo del CERN, el Consejo Europeo para la Investigación Nuclear. Para llevar a cabo su trabajo, el CERN se nutre de la participación y colaboración de los fabricantes del sector de las TIC como Intel, HP, Oracle o Siemens.

Driving past a few towers this morning I remembered a conversation I had a while ago. Why don’t they mount wind turbines or solar panels to the towers? Some of the new turbines are cheaper and quieter than before. Something like the Conenergy “Proven 15” which can generate enough power for 6 homes should make a big difference to the carbon footprint of an individual tower.

Most towers are in suburban areas and sound from turbines could be an issue. Some of the sub 6kW turbines 30-40m up a pole are not going to make too much noise. There will always be that one little old man who needs to write another complaint letter.

There are also new turbine designs like the Helix being  tested in the US which looks like a ripped-in-half colorbond water tanks. The trial of turbines in the progressive US state of California will be watched closely by network providers world wide (or should be). More information on the Helix test.

“Helix remains committed to developing innovative solutions that can power cell phone towers with wind power,” noted Ian Gardner, Helix Wind CEO. “We are actively pursuing opportunities in this space, and are excited to be working with Core Communications on a test so close to home.

Even grid connected cell phone towers can benefit from renewable energy, and wind power can dramatically reduce the emissions and carbon footprint associated with them. Under the right conditions, the towers may even be able to produce surplus energy, providing an additional revenue stream to tower owners. We look forward to getting started on the test.”

The idea would be power the tower’s electronics or to at least supplement. Any surplus stored or sent into the grid.

Optional solutions – off-grid.

It seems that in the developing world, where electric grids are less reliable or non existant many phone towers have to generate their own electricity. Many of these are powered with diesel generators. With new efficient systems the cost per kW has dropped but fuel and maintenance increases this may not be sustainable. I’ve also read that theft and vandalism are also a big problem in some parts of the world. Bio-diesel is another option but it may take the next generation of diesel mechanics to make it a real sustainable option. Many options are now available for solar and wind that have small land footprint.

Aesthetics

Ericsson has created the Tower Tube a self contained concrete tower that has less visual impact and a smaller carbon footprint. Since they use concrete instead of a steel these towers release approximately 20% less CO2 than conventional towers. Funky tower design concepts / APRS Solar / Wind / Weather montioring on a steel tower

Fake Trees (errk) Throughout northern San Diego County, these trees are springing up everywhere. Unlike most trees that take many decades to grow, these “new” trees appear within days. They are commonly used in indoor landscaping and to camouflage unsightly communication towers.

From a quick search design of practical and aesthetically pleasing (well better than the ones in Melbourne) towers. I’ll drop in more images as I come across them such as the Sunflowers below.

A few weeks ago I started my work placement, in the electrics department on an ABC comedy — Lowdown, written by Adam Zwar and Amanda Brotchie. Production goes on as we speak, but I’ve already wrapped because I went to Bali for a week and got replaced. Fair enough. But still.. it frustrates me that I couldn’t come back in some capacity, as I was just starting to feel comfortable doing my job before I had to leave, and being on a professional set was an incredibly valuable experience in general. Sucks that I couldn’t stay on for the 6 weeks of shooting. But that’s the way it had to happen, as I’d already locked down other commitments before I knew that I’d have the work attachment. I got a call from Rachel Wilson and rocked up to production the next morning, very short notice, and as a result my working schedule was very erratic.. I tried to fit Lowdown in wherever I could. Anyway, it pains me that I couldn’t work for longer, but regardless, the placement was awesome, so all is well.

Right. So technically I was working as a “lighting assistant”, under the command of Darryl (the gaffer) and Chris (the best boy, but a gaffer in his own right). On a professional shoot there are so many more roles, a much larger and more disciplined hierarchy, and even the lowest roles are occupied by extremely skilled people (I’m not meaning me). Chris gave me great guidance throughout my time on Lowdown, and Darryl made sure I learned from my mistakes. It feels quite harsh at first, very old-school to be verbally punished for slipping up, but it works. You grow a thick skin and make sure to do things better next time.

For now, I want to regurgitate some of the things I’ve learned about lighting while on set.. technical things. I’ll come back to my actual experience of the production at a later date. So.. from here on, it’s all raw information. Enjoy.

HMIs
HMIs are extremely efficient lights. A 1.2K HMI outputs about as much light as a 5K tungsten lamp. Hence you can blast your scene with light without tripping any circuit breakers as you’re well under 2400W. HMIs are also extremely expensive and potentially dangerous — all HMIs are covered by a special sheet of UV-filtering glass. Without this sheet of glass, the light could literally burn your skin off because of the extreme UV output (you can get sores from ~1-2 minutes of direct exposure). Note that UV is on the complete opposite side of the light spectrum in relation to red and infra-red — the primary output of tungsten lights. Hence it follows that HMIs have a stronger output of blue light, running at 5600K (daylight temperature), and are used to mimic sunlight (which is why ARRI’s HMIs are labelled ‘ARRISun’). Also, as the light functions by sending an arc of electricity through mercury vapour, the current would alternate and the light would flicker without a ballast. The ARRI ballasts are relatively small and extremely quiet, but as a rule, the ballast must be connected to the HMI BEFORE it’s plugged into power, or there’s a chance that the ballast explodes.. not pretty. As with other high output lights, HMIs become extremely hot, meaning that if cold rain falls onto the lens or UV-filtering glass, the drastic change in temperature could crack or shatter the glass.. again, not pretty.
Anyway. If someone asks for a 575W HMI PAR to be set up, here’s what you need:
The lamp itself (an ARRIsun 5, or 575, is about the size of a 1K ARRI tungsten lamp, very high output for such low wattage)
The header cable (connects lamp to ballast)
The ballast
The lens box (PAR lamps are used with lenses that disperse the light in various ways. The default setup is to insert the green lens unless otherwise stated)
The stand (generally not a C-stand, something sturdier such as an Avenger combo, made specifically for lights, with two sizes of spigot)
A shotbag

Fluorescents
A 4-ft kino box is freaking heavy. It’s long, unwieldly, and does my back in. Seasoned gaffers and best boys obviously get by, but otherwise it’s a two-man job.
A 4-ft kino runs at 75W per tube on high power. We were using a 4-bank (ie 4 slots for tubes) which ultimately pulls 300W max.. that’s incredibly efficient, considering the light output of the 4-ft tubes. The kino ballasts allow for each tube to be turned on and off individually, so that intensity and colour temperature can be manipulated on the fly. Each kino box comes with a set of tungsten and daylight balanced tubes — you can tell the difference by the colouration at the ends of each tube (blue socket means daylight). A “mixed grille” is where you’ve installed one tungsten tube, then a daylight, then a tungsten, then a daylight. This makes the colour temperature 4400 — right in the middle of 5600 and 3200. It’s important that you alternate between tungsten and daylight tubes to ensure the colour temperature remains even.. or else half the frame will be daylight and the other half tungsten.. you get the picture.

DIY Lighting
On many days of the shoot, Darryl chose to use home-made lights for different purposes. The most popular was the China ball, which is exactly what it sounds like. A regular tungsten bulb inside a china ball to soften the light and spread it in all directions. Good for a fill, but it’s a bitch to gel because you’ve got to get a sheet of CTB inside the ball and clamp it into position without hurting the paper on the outside.. c’est difficile.
Another DIY light I saw on set was the spacelight. It consisted of 4 long incandescent bulbs arranged on a metal cross inside a cylinder of diffusion. You unzip the diffusion like a tent if you need to gel it or change the bulbs. I’m fairly sure that you hang the spacelight high above the scene to provide a reasonably soft toplight and/or fill. It’s a lightweight construction, easy to hang, and provides quite a bit of light as it’s made from 4 redhead bulbs.

Frames, grids and diff
Lowdown is an ABC comedy. Lighting on set required a great deal of softening compared to what I was used to on student films. To simulate the sun, we’d run the big 1.2K HMI behind a mammoth frame of grid or diff. Essentially, you piece together a large metal frame and tie a large square of diffusion material to it, then clamp the frame onto two C-stands and set it up in front of the light. The diffusion material comes in various strengths, and ‘grid’ is different to straight diffusion (or ‘diff’). Softness also varies depending on the distance between frame and light source. The further away you move the frame of diffusion, the greater the softness, but light output lessens dramatically as well. Hence you need huge lights behind the frames if you want to make the scene ultra-soft. And the larger your frame, the softer the lighting quality, hence the huge frames that must be broken down into separate components to fit into the truck

Lighting safety
Shotbag everything.
Gaff down cables where people are likely to walk
When lighting indoors, watch for water sprinklers, and if necessary, tape a cup over each sprinkler to make sure it doesn’t overheat and destroy your equipment. (when taping things to ceilings, stick the tape to your shirt a few times to make sure that it won’t pull paint off the walls)
When lighting outdoors, prepare for rain by pegging rolls of hogwire over lights and ballasts. Hogwire is a robust mesh coated in waterproof resin.. it’s very noisy, so you’ve got to be careful with it during a take.
When hogwiring ballasts, make sure that there’s enough space for them to ‘breathe’.. they need some space around them to prevent overheating.
Don’t touch lightbulbs that draw more than 200W of power. It’s a universal rule.. I previously thought it only applied to Quartz-halogen bulbs, but the deal is that anything drawing so much power will run extremely hot— touching these bulbs impregnates them with natural oils from your skin, and said oils will superheat and may explode the bulb.. so many potential explosions in lighting dept..

ClassAds enable a lot of power in Condor. ClassAds are the data representation used for most everything in Condor. Generally, a ClassAd is a set of name-value pairs. Values are typed, and include the usual suspects plus expressions. In Condor, jobs, users, slots, daemons, etc. all have a ClassAd representation with their own set of attributes, e.g. a job has a Requirements attribute whose value is an expression such as FreeMemoryMB > 1024, and a slot has a Memory attribute whose value is the amount of memory allocated to the slot.

ClassAds are schema-free, which means they can be arbitrarily extended. Any given ad can have any attribute a user or administrator wants to put in it. Attributes are given meaning by when and where they are referenced.

On a slot there are different classes of attributes. Resource statistics, such as Disk and LoadAvg; resource properties, such as NumCpus and HasVM; policy expressions, such as Requirements or Rank; etc.

One attribute not provided by default on a slot is a statistic representing the total amount of free memory on the system. There are multiple interpretations of what free memory might really mean. On Linux, it could be the number in the free column on the Mem: row reported by the free program, e.g.

$ free -m
             total       used       free     shared    buffers     cached
Mem:          2016       1790        225          0         93        845
-/+ buffers/cache:        851       1165
Swap:         1983          0       1983

or it might be the value on the buffers/cache line. It might be some combination of totalram, freeram, sharedram, bufferedram as reported by sysinfo(2). It might also include information about totalswap and freeswap, also from sysinfo(2).

The meaning is often a function of what kinds of policies are desired in a Condor deployment.

Once you have picked a meaning for your deployment, Condor provides you with the STARTD_CRON mechanism to include a FreeMemoryMB attribute in your slot ads. From there the attribute can be referenced by policy on jobs, during negotiation, and slot policy.

You need two things: first, a way to calculate the value for FreeMemoryMB, we’ll use the simple bash script below that pulls FreeMem: out of /proc/meminfo; second, configuration available to the condor_startd to run the program.

free_memory_mb.sh:

#!/bin/sh

FREE_MEMORY_KB=$(grep ^MemFree < /proc/meminfo | awk '{print $2}')
echo "FreeMemoryMB = $((FREE_MEMORY_KB / 1024))"

condor_config.local:

STARTD_CRON_JOBLIST = FREE_MEMORY_MB
STARTD_CRON_FREE_MEMORY_MB_EXECUTABLE = $(LIBEXEC)/free_memory_mb.sh
STARTD_CRON_FREE_MEMORY_MB_PERIOD = $(UPDATE_INTERVAL)s

Notes: First, the documentation is out of sync with 7.4.0 and the units on _PERIOD must be specified; second, UPDATE_INTERVAL needs to be defined, it specifies how often the condor_startd will periodically send updates to the Collector.

After reconfiguring the Startd, or just restarting condor, you can view the new attribute with condor_status:

$ condor_status -long  | grep ^FreeMemoryMB | sort | uniq -c
     10 FreeMemoryMB = 174

Yes, the values are different between FreeMemoryMB and free. The amount of free memory is changing constantly and we are just sampling it. You can increase the sampling rate, but beware that means you will generate more frequent updates to the Collector. Maybe not a problem when you have 32 machines and 256 slots, but definitely something to consider when you have 3000 machines and 24000 slots.

Final note: A better name for the attribute representing free memory on a system is TotalFreeMemoryMB to remain consistent with other attributes. For instance, Disk is a slot’s share of the TotalDisk free on the system.

Heya,

there are still some outfits I put toghether for you after my shopping tour. This one is spicy, comfortable, but still has an elegant look. And…its red , and, what may be the best, you don#t have to spend a fortune for this style!!

As I am not a lover of real fur, but do like the look, I absolutely fell in love with this wonderful faux fur jacket. From the different available colors, i decided to get the red one, thinking about matching it with my red bax boots. Simone has a lot of nic and really reasonable clothes, you really should have a look there!! Matching the Simone faux fur jacket, my eyes fell on a turtleneck at Simone in a nice rust tone. I just added a simple black jeans from coco and a simple leather belt from Maitreya, which is in a faded red and rounded my look. Looking for a hairstyle to go with it, I remembered the sale at Truth and got this great style for little money. Some simple , but fantastic crafted gold studs from gems & kisses as the icing on the cake and I feel great dressed for an autumn day, or even an early winters days, bringing some color into the grey days and matching the red falling leaves, this season brings us. I hope you liked my outfit tip and I would highly recommend to check out these stores!

Stay tuned, my bag isn’t empty yet…*LOL

Yours,

Svenja
