This article examines how coaching using questions could assist novice teachers to promote mathematical thinking and discussions within time-constrained programmes.
Videos of rehearsals, reflective debriefs, and student teacher surveys were collected across a range of courses over 4 years.
Findings included that student teacher roles in rehearsals were enhanced through coaching with questions and co-construction was enabled. Coaching questions exposed effective practice, particularly in relation to orchestrating mathematical discussion, enabling student teachers to reflect, discuss, make decisions, and immediately trial teaching strategies. Questions appeared to lengthen rehearsals but improved their effectiveness through enhancing participation and enabling co-construction of meaning. Findings indicate that questions used in coaching of rehearsals inform and empower novice teachers, essential factors within initial teacher education for equitable and ambitious mathematics teaching.


How to copy file to s3 with aws cli example
This brief post will show you how to copy file or files with aws cli in several different examples. It will cover several different examples like:
 - copy files to local
 - copy files from local to aws ec2 instance
 - aws lambda python copy s3 file
You can check this article if you need to install and download files with S3 client on Linux Mint or Ubuntu: How to Download Files from S3 Bucket with AWS CLI on Linux Min
Step 1: Copy files to local with aws cli
One the S3 client is installed and correctly configured(check the link above). You can copy files from a S3 bucket to your local machine by command:
aws s3 cp
and example would be
aws s3 cp s3://some-space_bucket/my-file.txt.
The command above will copy the file located on bucket - s3://some-space_bucket/my-file.txt on the current working folder.
Step 2: Copy files to local with different AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
What about if you like to get files from a bucket which has different AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY from the configured one. And you don't like to store them on your machine.
In this case you can use the next command to copy files with custom keys:
AWS_ACCESS_KEY_ID=xxx AWS_SECRET_ACCESS_KEY=xxx aws s3 cp s3://some-space_bucket/my-file.txt.
Step 3: Copy files from local to S3 bucket
If you need to copy a local file from your local machine to aws instance then you can use the next syntax:
aws s3 cp
or as example:
aws s3 cp./test.txt s3://some-space_bucket/my-file.txt
This will copy the local file test.txt from the current working folder to the bucket path: s3://some-space_bucket/my-file.txt
Step 4: Python aws lambda to copy S3 file(s)
If you need to create a aws lambda to copy files from S3 buckets you can check: Using an Amazon S3 trigger to invoke a Lambda function
The Python lambda to copy files is:
import json
import urllib.parse
import boto3
print('Loading function')
s3 = boto3.client('s3')
def lambda_handler(event, context):
 # Get the object from the event and show its content type
 key = urllib.parse.unquote_plus(event['Records'][0]['s3']['object']['key'], encoding='utf-8')
 response = s3.get_object(Bucket=bucket, Key=key)
 return response['ContentType']
 except Exception as e:
 print('Error getting object {} from bucket {}. Make sure they exist and your bucket is in the same region as this function.'.format(key, bucket))
 raise e
Step 5: Python aws lambda to copy S3 file from one bucket to other
If you need to copy files from one bucket to another with a aws lambda you can use next Python snippet:
import boto3
import json
s3 = boto3.resource('s3')
def lambda_handler(event, context):
 bucket = s3.Bucket('some-space_bucket-1')
 dest_bucket = s3.Bucket('some-space_bucket-2')
 for obj in bucket.objects():
 dest_key = obj.key
 s3.Object(, dest_key).copy_from(CopySource = {'Bucket': obj.bucket_name, 'Key': obj.key})
This will copy all files from some-space_bucket-1 to bucket some-space_bucket-2

Octopus Deploy Documentation
Coordinating multiple projects
Last updated
When working with multiple related projects, it is often necessary to co-ordinate between them and take some action that depends on their combined status. For example, ensure a related project is deployed first or send an email when all projects are deployed. This section discusses some approaches to this problem and provides some examples showing how to query and control projects programatically.
For in depth code samples covering many of the processes discussed in this section, see the Project Coordination Code Samples page
Responding to events across multiple projects
There are various ways to respond to events within Octopus, which is useful for:
 - Sending an email after a set of projects is deployed.
 - Generating a report of the day's deployments.
 - Promoting all projects from one environment to another at a certain time.
 - Triggering another process, for example, another deployment.
 - Verifying that some conditions have been met.
The simplest trigger is a periodic timer setup through a Windows schedules task, Azure Function, or as a windows service. Alternatively, it can also be a project within Octopus as a project that re-queues itself when run (see the samples).
Subscriptions can call a web service or send an email when Octopus events occur.
The event can also be a script step in a project. If the script is defined as a step template it can be shared among the related projects. However, it is difficult to ensure that two copies of the script do not run at the same time.
Orchestrating the deployment of multiple projects
Below are two different approaches to orchestrating multiple projects. Depending on the projects and requirements, one or a combination of these two approaches may be used. This orchestration is useful for when:
 - A set of projects should always be deployed together or in a specific order.
 - A project depends on a certain version of another project.
 - A project should not be deployed while another project is being deployed.
 - A certain step should not execute at the same time as a step in another project.
Parent project
This approach consists of creating a project that co-ordinates the deployment of other projects and any other related actions. For example it could define steps that:
 1. Deploy and wait for projects A and B.
 2. Send an email informing users Project A and B have been deployed.
 3. Deploy project C.
 4. If the deployment of project C fails, redeploy an older version of A and B.
Cooperating projects
This approach consists of each project taking on the role of checking that the other projects are in the right state so that it can deploy itself. It is usually implemented as one or more script steps. For example the project could:
 - Trigger a deployment of Project A if it has not been deployed to the environment.
 - If Project B is running, wait for it to reach step 3.
Deploy release step
The Deploy Release step is helpful when implementing the Parent Project or Cooperating Projects approaches described above. It makes it simple to deploy a release of a project from another project.

The hydrothermal corrosion behavior (320 °C, 20 MPa, 168 h) of high-purity chemical-vapor-deposited (CVD) SiC pre-irradiated with 5.1-MeV Si ions at 400 and 800 °C and 0.1-2.6 dpa was studied in order to clarify the effects of irradiation damage on SiC corrosion. Regardless of the pre-irradiation conditions, selective corrosion was observed at the grain boundaries and stacking faults even at the unirradiated regions. In contrast to the complete loss of the irradiated regions observed in the specimens irradiated at 400 °C during the autoclave test, a number of large grains survived in the case of the specimens irradiated at 800 °C. The corrosion rates at the irradiated regions increased with increasing irradiation fluence, with a significant dependence in the lower dpa regime similar to that observed in the point-defect swelling. SiO2 formation was not detected in any case. Cross-sectional scanning transmission electron microscopy (TEM) and electron energy loss spectroscopy (EELS) analyses of the surfaces of the surviving grains revealed oxygen diffusion to a depth of 3.0 nm from the surface. A significant reduction of the oxygen diffusion barrier at the surface was implicated as one of the key mechanisms of the acceleration of the ion-irradiated SiC corrosion rates.

The ability to adapt is critical to survival and varies between individuals. Adaptation of one motor system may be related to the ability to adapt another. This study sought to determine whether phoria adaptation was correlated with the ability to modify the dynamics of disparity vergence. Eye movements from ten subjects were recorded during dynamic disparity vergence modification and phoria adaptation experiments. Two different convergent stimuli were presented during the dynamic vergence modification experiment: a test stimulus (4° step) and a conditioning stimulus (4° double step). Dynamic disparity vergence responses were quantified by measuring the peak velocity (°/s). Phoria adaptation experiments measured the changes in phoria over a 5-min period of sustained fixation. The maximum velocity of phoria adaptation was determined from an exponential fit of the phoria data points. Phoria and dynamic disparity vergence peak velocity were both significantly modified (P < 0.001). The maximum velocity of phoria adaptation was significantly correlated with the changes in convergence peak velocity (r > 0.89; P < 0.001). There was a strong correlation between the ability to adaptively adjust two different oculomotor parameters: a tonic and dynamic component. Future studies should investigate additional interactions between these parameters, and the ability to adaptively change other oculomotor systems such as the saccadic or smooth pursuit system. Understanding the ability to modify phoria, dynamic disparity vergence, and other oculomotor parameters can yield insights into the plasticity of short-term adaptation mechanisms.

text: The initial molecular steps of the acid-catalyzed silica sol−gel process de-parting from tetraethylorthosilicate (TEOS) were investigated by in situ 29Si NMR and UV−Raman spectroscopy. The use of a substoichiometric H2O:TEOS molar ratio (r-value 0.2−1.2) slowed the silicate oligomerization reaction and allowed unraveling the initial steps of silica condensation. Molecular modeling confirmed Raman signal and 29Si NMR shift assignment. A comprehensive listing of all Raman and 29Si NMR assignments is provided, including unique Raman assignments of cyclosilicates and the linear tetramer. The combination of experiment and modeling allowed an analysis of the reaction kinetics. The derived kinetic model and the experimental observation both revealed that the H2O:TEOS molar ratio had a strong influence on the reaction kinetics but not on the reaction pathways. The multianalytical approach led to development of an oligomerization scheme. As dominant oligomerizations, chain growth, cyclodimerization, and branching were identified. Under the investigated conditions, chains did not grow longer than pentamer, and ring sizes were limited to 6-rings. Chains of 4 Si atoms and 4-rings were abundant species. Branched rings and chains were formed by attachment of dimers and trimers. Gelation proceeded from branched 4-rings and branched chains with limited hydroxyl functionalities.

Ecosystem stability: How a Plant Community Blows Off Wind Pressure
This research paper aims to understand how Aruba's plant ecosystem is shaped and affected by the constant wind pressure present on the island. This was achieved by evaluating and comparing multiple variables related to ecosystem stability, resilience and service provision with wind exposure (leeward and windward) and wind strength through data collection and analyses and a literature review. Results showed leeward sides present higher plant population, density and species richness, while windward slopes present higher biodiversity. Furthermore, the slopes with the highest wind strength were found to have the highest variations between exposure and the lowest values. These results point to the wind having an apparent hindering effect on plant population, richness and cover while showing that biodiversity is a more robust characteristic and could thus remain unchanged under environmental stress. Defining which slopes present higher stability and resilience cannot be concluded, but windward slopes, which present plant deformation and patchy distribution, could be better adapted to stronger winds that could occur with climate change, than leeward slopes, which have vegetation that is less affected by current conditions.


Take the 2-minute tour ×
At the behest of Gerhard Paseman I'll describe the problem that I alluded to in name for a partial order.
Let $M = M(\infty)$ denote the set of all finite subsets of the positive integers $\mathbb{N}$. As I mentioned in my other question, $M$ has a partial order defined as follows: If $S \in M$ and $i \ge 1$ is an integer, denote by $S_i$ the $i$-th largest element of $S$. We say that $S \ge_R T$ if $|S| \ge |T|$ and $S_i \ge T_i$ for $i = 1, \dots, |T|$. For any finite subset $A \subset M$ define the polynomial $$ f_A(t) := \sum_{S \in A} \sum_{T \in A} t^{|S \Delta T|},$$
where $S \Delta T$ denotes the symmetric difference. If $ p \in (0,1)$ say that a finite subset $A \subset M$ is optimal at $p$ if $f_A(p) \ge f_B(p)$ for all subsets $B \subset M$ with $|B| = |A|$. Say that $A$ is optimal, if there is some $p \in (0,1)$ for which $A$ is optimal at $p$. Say that $A$ is isomorphic to $B$ if there is a permutation $\pi \in S_{\infty}$ (permutations of $\mathbb{N}$ which only move a finite set of elements) and a subset $T \in M$ such that $B = \{ \pi(S) \Delta T : S \in A \}$. It's easy to see that if $A$ is isomorphic to $B$ then $f_A(t) = f_B(t)$.
Another way of thinking of $M$ is to consider it to be infinite sequences of 0's and 1's with only a finite number of 1's (i.e. infinite bit-strings). Then cardinality becomes Hamming weight and symmetric difference becomes exclusive or. Isomorphic sets of bit-strings would be obtained from one another by permuting coordinates (every bit string in the set gets permuted in the same way), and then xoring everything with a common bit-string.
In (Gordon, Miller, Ostapenko) we proved that if $A$ is optimal then it is isomorphic to an order ideal for the order $\le_R$. For a fixed value $N$ for $|A|$ we were then able to make a search for all order ideals of size $N$, and then determine the optimal ones (for some $p$) among those. We were able to do this by looking at the subposet of $M$ of elements $S \in M$ such that $|\{ T : T \le_R S \}| \le N$. In particular we were interested in optimal sets whose cardinality is a power of 2. The search for cardinality 64 took about 1/2 hour. Unless we have a new idea the search for $N=128$ is out of the question. For $N=64$ there are _PHONE_ order ideals of cardinality 64, but less than 100 of them are optimal. Thus I was hoping that if there are theorems around about the structure of the order ideals of $M(\infty)$ that that might help us to make a more efficient search. In the previous question, Richard Stanley pointed out that the partial order that I was using had been studied before in one of his papers.

Thank you for showing this problem. I assume in the definition of A isomorphic to B you want B= instead of A=. Also, I apologize for an earlier error. The partial order I and Libor Polak used involved multisets, not sets, of the positive integers. I shall contemplate upon this problem. Gerhard "Ask Me About System Design" Paseman, 2011.08.11 – Gerhard Paseman Aug 11 '11 at 19:03
Also, it is easy for me to get confused. A in M suggests that A is a set of numbers. A finite set A from M is a finite subset of M. By a finite set A in M I am guessing you mean the latter, but I would expect A subset M instead of what you have, which is A in M. Can I consider it a typo, and mentally substitue the subset symbol for the member of symbol in those places to get your meaning? Gerhard "Ask Me About System Design" Paseman, 2011.08.11 – Gerhard Paseman Aug 11 '11 at 19:11
_USER_: I fixed the typos (I think that I got all of them). One other thing: you can also define a different partial order on subsets of M: Say that $A \ge_D B$ if $f_A(t) \ge f_B(t)$ for all $t \in (0,1)$ (the $D$ is for dominates). It's necessary (but not sufficient) for $A$ to be maximal in this partial order (at least restricted to sets of cardinality $|A|$) in order for it to be optimal. I found empirically that almost all of the maximal sets for $N=64$ were optimal. – Victor Miller Aug 11 '11 at 22:36

How can I make a consecutive numbering with my e-mark?
Creating a consecutive numbering imprint in the app
To create a numbering imprint, go to "New imprint" and "start without template". In the editor you can add a numbering element to your imprint. Alternatively, you can choose one of the pre-installed numbering templates and click on the numbering element.
You can choose the following numbering settings:
 - Starting point/First number
 - Steps to count upwards
 - Digits of your number (00123 would be 5 digits)
 - End point of your numbering
 - Change after 'x' imprints (an imprint/number can be printed several times before it counts upwards)
 - Define a prefix or suffix to your number
Printing consecutive numbering imprints:
Since one of the latest updates, imprints with numbering function are automatically counted up from the e-mark. For this purpose, a numbering has to be added in the editor or a template has to be selected from the numbering category. Then send it once to the e-mark, the rest will be done by the e-mark itself. The e-mark continues to count even if the app is closed or the e-mark is switched off between two prints.
Please note that prints with numbering function cannot be stored on the e-mark at the blue, pink and orange positions or added to the print queue.
Furthermore, please note that by removing the battery or having had a battery level of 0 %, the e-mark resets numbering and will not print the right information any more.

This example shows how to use the Graph Cut option in the Image Segmenter app to segment an image. Graph cut is a semiautomatic segmentation technique that you can use to segment an image into foreground and background elements. Graph cut segmentation does not require good initialization. You draw lines on the image, called scribbles, to identify what you want in the foreground and what you want in the background. The Image Segmenter segments the image automatically based on your scribbles and displays the segmented image. You can refine the segmentation by drawing more scribbles on the image until you are satisfied with the result.
The Graph Cut technique applies graph theory to image processing to achieve fast segmentation. The technique creates a graph of the image where each pixel is a node connected by weighted edges. The higher the probability that pixels are related the higher the weight. The algorithm cuts along weak edges, achieving the segmentation of objects in the image. The Image Segmenter uses a particular variety of the Graph Cut algorithm called lazysnapping. For information about another segmentation technique that is related to graph cut, see Segment Image Using Local Graph Cut (Grabcut) in Image Segmenter.
Read an image into the workspace. For this example, read the sample image
baby.png into the workspace.
b = imread('baby.jpg');
From the MATLAB® toolstrip, open the Image Segmenter app. On the Apps tab, in the Image Processing and Computer Vision section, click Image Segmenter.
On the app toolstrip, click Load, and then select Load Image from Workspace. In the Import from Workspace dialog box, select the image you read into the workspace. The Image Segmenter app displays the image you selected.
You can also open the app using the
imageSegmenter command, specifying the image:
On the Image Segmenter app toolstrip, select Graph Cut.
The Image Segmenter opens a new tab for Graph Cut segmentation. As a first step in Graph Cut segmentation, mark the elements of the image that you want to be in the foreground. When the Image Segmenter opens the Graph Cut tab, it preselects the Mark Foreground option. To mark an object as foreground, draw a line (also called a scribble) over the object. When you draw a line, try to include all the different values in the object you want to segment. You can draw as many separate lines as you like. If you are not satisfied with the lines you draw, you can always edit them. Click Erase and move the cursor over any part of the line you want to remove. If want to start over, click Clear Markings.
Next, click Mark Background and draw scribbles to mark the elements of the image you want to be the background. When you finish drawing the lines, the Image Segmenter immediately performs the segmentation (shown in blue).
To refine the segmentation, continue drawing foreground and background lines. For example, there are several areas near the bottom of the image that need to be removed from the foreground. To fix these problems, draw additional background lines on these parts of the image.
To get a better look at the segmentation, click Show Binary.
When you are satisfied with the segmentation, click Create Mask in the toolstrip on the Graph Cut tab. The app closes the Graph Cut tab and returns you to the Segmentation tab.
When you return to the main Segmentation tab, you can use tools to refine the mask image, such as Morphology and Active Contours. To save the mask image, click Export. You can also use the Export option to obtain the code the Image Segmenter app used to create the segmentation.

Canada Chemical Management Plan – Canada Challenge
About The Canada Chemical Management Plan
Canada's Chemicals Management Plan aka the "Challenge" regulates chemicals that are harmful to human health or the environment. The Prime Minister, along with the Ministers of the Environment and Health put the "Challenge" into effect on December 8, 2006. The Chemicals Management Plan is the collection of information on the properties and uses of approximately 200 chemical substances identified through the categorization process as high priorities for action. Under the "Challenge", approximately 200 substances of the highest priority were divided up into a number of smaller groups of substances. The Government is using the mandatory information gathering provisions of section 71 of the Canadian Environmental Protection Act, 1999 (CEPA, 1999) to gather information that is deemed required for improved decision-making. Industries are being invited to submit additional information that may be used to inform risk assessment and to develop and benchmark best practices for risk management and product stewardship.

"The truth will set you free, but not until it's finished with you." David Foster Wallace
Have choices you made in the past led to consequences that are still working themselves out?
When you look back on those turning points, have you felt that the truth was right there but you missed it? Or that you persuaded yourself not to believe it?
Regret can can be a motivator for change, and can facilitate our journey to truth.
Writing helps.

Most of you had created many programs for various purpose. But have you ever thought of some animation in your program..
Here I am going to mention a small tutorial on creating a blinking text effect. It is for pure beginners.
First of all open the Visual Basic using Start>Programs>Microsoft Visual Studio>Visual Basic 6.0.
Then select Standard EXE and click open.
You will get a blank Form.
From the toolbox(in left side), select Command Button and create two buttons in your form(say, Command1 and Command2).
Also, create a Timer in your form(say, Timer1)
Then open the code window(View menu> View Code).
Then write the code as below:
Private Sub Command1_Click() Timer1.Interval = 100 'interval of the timer Timer1.Enabled = True'starting the animation Label1.Caption = "Welcome" 'text to display End Sub Private Sub Command2_Click() Timer1.Enabled = False'stopping the animation End Sub Private Sub Form_Load() Timer1.Enabled = False 'disabling the animation on loading the form End Sub Private Sub Timer1_Timer() If Label1.Visible = True Then 'checking whether it is visible Label1.Visible = False 'if visible then, make it invisible ElseIf Label1.Visible = False Then 'checking whether it is invisible Label1.Visible = True 'if invisible then, make it visible End If End Sub
I had included most of the comments in the code itself. I think you understand my coding. If you have any doubt, please feel free to contact me....

Automatically update and restart node applications when you push to GIT.
TF Monitor (Work in Progress)
Note: TF Monitor, at this point, isn't being written with Windows in mind. Only Linux and Mac OS. Also, we expect your system to have git, cron and node installed in the default locations.
TF Monitor automatically restarts node applications when they crash or any file in their directory changes. In the future you will be able to:
 - specify an application to launch on bootup
 - automatically update and restart your app whenever you push to GIT
npm install -g tfmonitor
Use sudo if necessary.
TF Monitor uses a file called Procfile placed in your project folder to launch your application. This file should contain one or more lines that:
 - start with a name followed by a colon
 - after the colon is the command to start your application
See the "Launch Application" section for example.
A package.json file with a valid name is also required.
Run the following from your applications root folder:
tfmonitor start web
Or, if you want to run tfmonitor in the foreground so you can use ctrl-c to stop it use:
tfmonitor start web --foreground
You may also enable logging for this command with the --log command line parameter. This is useful if you want to know when your application restarts or you want to see any errors thrown by TF Monitor (the software is still early in development, so don't rely on it in a production environment).
Your Procfile for this example should look like:
web: node myapp.js
tfmonitor stop web
Where web is the command name in your Procfile.
tfmonitor register web
Note that your application will start on boot without using tfmonitor for restarting... This will change soon.
tfmonitor unregister web
tfmonitor list
This will return a list of running applications each with a pid and name. Note that the pid is for the tfmonitor process that is monitoring your appliction and not your application itself. If you kill this process it will not automatically restart like your application will.
First, make sure your application is fully setup to work with GIT. Try a git pull from your apps root directory.
Once this is working simply add -git to your start or register command like so:
tfmonitor register web -git
This will do a git pull once per hour. The advantage of this is your computer can be behind a firewall with no exposed ports.
The following features are not yet implemented. This defines how we plan to make them work in the future!
If your computer is not behind a firewall, or you have the ability to open ports, the better way to setup git is to use a "hook". Your hook should point to:
Then use our -githook [port] command like in the following example:
tfmonitor register web -githook 8989
Note that tfmonitor will run a small web service on your chosen port and that the application tfmonitor runs cannot use the same port.

[ki-ga uku]
Literal translation: Wood floats.
Meaning: wood is such a material, if to put it in water, it will stay on the top, it will not sink.
Let's add ～やすい / ～にくい pattern (as auxiliary adjective, not i-adjective).
[ki-wa uki-yasui]
Literal translation: Wood floats well.
Meaning: wood is a good floating material, that it is a good itea to make something floating from that, for example, a boat.
Question: why -yasui/-nikui makes us use は instead of が?
Is it legal to say [木が浮きやす] or with ga-version of -yasui/-nikui we make some shift in meaning?
Good question! This question is an actually an entire topic. For example, see this article.
So we have four patterns here:
(1) 木が浮く
(2) 木は浮く
(3) 木が浮きやすい
(4) 木は浮きやすい
The short answer is that they are all correct grammatically. However, they have slightly different nuances.
"は" is called the topic particle for good reason; it marks what the speaker's statement is about. Without any context, (1) could be a statement about the environment from a book. The statement describes what simply happens. On the other hand, (2) is a statement about the tree itself. An example usage is, 石は浮かないが木は浮く (Stones don't float, but trees float). Here, we compare stones and trees. The statement isn't about what happens generally; it specifically compares stones and trees, the topics.
Now, alone, (3) seems slightly strange alone. Note that as "浮きやすい" is an adjective, the whole sentence seems to describe the tree, which wouldn't make sense if tree weren't the topic. On the other hand, it could be used as in "なぜ、海水では人が浮きやすいのでしょうか". Here, the topic is seawater; not people.
(4) alone is a natural statement about trees themselves. It describes trees, saying trees float easily.
I hope this helps a little bit!

How to Stretch Content Across the Funnel
Everyone has different preferences when it comes to consuming content. The same person's preferences might even change based on what day it is, what time it is, what device they're using, or any number of unpredictable factors.
As a result, B2B marketers are challenged to produce content in a variety of formats in order to appeal to the widest possible range of audiences.
Of course, creating even a single piece of content can be time-consuming. But if you consider each asset you produce as part of a larger package, you can easily stretch that individual piece of content into multiple assets that fit all stages of the funnel.
Here's an example of how one report sparked the creation of many more assets to support prospects all the way through the funnel:
- Highlights video: B2B Content Marketing Spotlight Report
- Blog post: Generate more leads with a variety of content formats
- Webinar roundtable: B2B Content Marketing Trends – Survey Results and Analysis
- Download: B2B Content Marketing Spotlight Report
Other ideas could include infographics, briefs, or video case studies. It's important to produce a mix of static and dynamic content, but rich media assets like webinars and videos play a particularly important role in nurturing prospects down the funnel.

Birth on the Land
Memories of Inuit Elders and Traditional Midwives
In Birth on the Land, elders and traditional midwives from ten Nunavut communities share memories of traditional birth.
They share how they sometimes laboured and birthed quietly and alone, while other times they were surrounded by the love and support of their family or community. They describe, and even demonstrate, what they did to facilitate an easy birth and give newborns the best possible start in life.
The elders and traditional midwives also share memories about the transition from giving birth in igluit or tents to having to do so in the company of strangers in institutions introduced by southern colonizers. They remember a time when pregnancy, birth, and death were accepted as a part of life, and when elders, rather than southern caregivers, were the sources of wisdom and authority.
Birth on the Land reintroduces contemporary readers to the time-honoured midwifery practices that were used in Nunavut for generations, and provides invaluable insight for caregivers in contemporary Nunavut about caring for pregnant women and giving birth the "Inuit way."

 - PARTNER IN CHARGE: Alessandro Orsini

 - TEAM: Ronald Dapsis
The proposal for the solar park takes on a mixture of environmental responsibilities and experiments in the form of pursuing new solutions to our persistent energy problems. In the process of finding further efficient ways to travel, the older roads are left behind unused. To invigorate the older route and give it purpose, we propose to combine the hard science of solar energy experiments and the soft ideals and principles of interacting with nature through parks while researching environmental and sustainable energy studies. The solar park emerges through phasing, which initiates between the furthest point away from the faster new route and the slower old route. The pressure from incoming and outgoing traffic engages the parts that are existing agriculture, indicated in yellow, and introduces the areas that can be allocated for solar energy collection and sustainable energy experiments, indicated in blue. We propose to convert the slower route as a bike route and along which both the agriculture and solar park begin mixing. The final phase would introduce a terracing technique along the side of the mountain when the solar park begins expanding past the plateau of the mountain and wind power collection coming of the sea along the viaducts. The introduction of the solar park can appear anywhere along the highway and can spread the entire stretch of Calabria from Bagnara Calabra to Scilla. The provisional cost for the first and second phases would be estimated lower than the cost of the destruction of the older route. Depending on how successful the solar proposals are in the first two phases, ideally the first two phases would self generate the costs of the third phase.

Satellite Image of Lake Carnegie in Australia
Lansat 7 (15m) Satellite Image of Lake Carnegie in Australia
Click on image to view in high resolution.
Lake Carnegie is an ephemeral lake in Western Australia. It fills with water only during very rare periods of significant rainfall, such as during the huge 1900 floods and in numerous recent tropical wet seasons when the monsoon and tropical cyclones have been moved south by recent climate change. In dry years, it is reduced to a muddy marsh.
Water entering the lake, unlike in more easterly playas of the Australian arid zone, does not come from well-defined river channels since the soils of the region are so weathered – lacking tectonic or glacial activity since the Carboniferous ice ages – that sediment is completely absent and the terrain so flat that only the most unweatherable rocks remain on the surface and well-defined river channels cannot form especially since the extreme age of the soils and consequent high rooting density of native flora limits runoff to an extreme extent.

Water Project H2Ooooh! is a TV-series of 3D cartoon animations that were created based on story boards developed by Italian schools. In 2010 this initiative was devised by Gruppo Alcuni in collaboration with the UNESCO Venice Office and Rai Fiction.
With "Water Project H2Ooooh!" 6,000 students ages 6 to 16 from 280 Italian schools were actively engaged to create a storyboard (or in other words a series of drawings representing the main scenes of a cartoon) on the theme of water and the issues related to its use, to its exploitation and to its limited supply. The schools took part in an educational course which included videos, books, etc which on the one hand allowed children to learn about the creation of animated cartoons and on the other hand it also encouraged a greater understanding of the situation related to water resources in our world today.
The project has been carried out during the 2008-2009 and 2009-2010 school years and was aimed at all teachers open to participating in a creative activity on the theme of water and science with their Primary or early Secondary school classes. The result is a 3-D animated television series in English and Italian (Italian subtitles) with six Pet Pals as main characters focusing on the issue of water protection, which has been broadcast on the public national broadcaster Rai Due in May and June 2010.

In normal line integration, from what I understand, you are measuring the area underneath $f(x,y)$ along a curve in the $x\text{-}y$ plane from point $a$ to point $b$.
But what is being measured with complex line integration, when you go from a point $z_1$ to a point $z_2$ in the complex plane?
With regular line integration I can see $f(x,y)$ maps $(x,y)$ to a point on the $z$ axis directly above above/below $(x,y)$.
But in the complex case, when you map from the domain $Z$ to the image $W$, you are mapping from $\mathbb{R^2}$ to $\mathbb{R^2}$ is not mapping a point to 'directly above/below' I don't have any intuition of what is happening with complex line integration.
share|cite|improve this question
It is not just that the function is not mapped "above" or "below", that actually doesn't change the intuition much (you can treat the real and imaginary parts separately if that were the only difference). The main difference is that the line elements $ds$ and $dz$ for the two integrations are very different. – Willie Wong Feb 17 '12 at 14:26
Instead of comparing with the scalar line integral, a much closer relative of the complex line integral is line integrals for vector fields. – Willie Wong Feb 17 '12 at 14:28

Forget about areas for the moment.
Consider the following situation: At the begin you are at the origin of the $x$-axis and have to compress a spring which is attached far away to the right. Assume that when the left end of the spring is at a given $x\geq0$ then it presses back with force $f(x)$. If the force were a constant $F$ then the work $W$ done when pushing a cart from $x_0$ to $x_1$ along the $x$-axis would be $W=F\cdot(x_1-x_0)$. But in our case the force is variable. When you compress the spring by pushing a cart to the right, and after some time you are at the point $a>0$ then the total amount $W$ of work done in this process is represented by $$W\doteq \sum_{k=1}^N f(\xi_k)\ (x_k-x_{k-1})\doteq \int_0^a f(x)\ dx\,$$ where $0=x_0 < x_1 < \ldots < x_N=a$ is a partition of the interval $[0,a]$, and $x_{k-1}\leq\xi_k\leq x_k$ $\ (1\leq k\leq N)$.
Analogously in the complex domain for the purpose of line integrals you should not consider the given $z\mapsto f(z)$ as a mapping of the $z$-plane to some other domain, but as a "complex scalar field" which defines at each point $z\in{\rm dom}(f)$ a certain "complex force" $f(z)$. For a constant such force $F\in{\mathbb C}$ the "complex work" done when pushing a cart from $z_0$ to $z_1$ along a straight line is given by $F\cdot(z_1-z_0)\in{\mathbb C}$, where $\cdot$ denotes the ordinary product in ${\mathbb C}$.
Assume now that you are given a curve $$\gamma:\quad t\mapsto z(t)\qquad(a\leq t\leq b)\.$$ Then the total "complex work" done when you push a cart along this curve would be represented by $$W\doteq \sum_{k=1}^N f\bigl(z(\tau_k)\bigr)\bigl(z(t_k)-z(t_{k-1})\bigr)\doteq \int_a^b f\bigl(z(t)\bigr) z'(t)\ dt =:\int_\gamma f(z)\ dz\.$$

As far as I can see, all this answer does is explain the definition of complex integration, and attach the word "complex work" to it. Despite being kind of catchy, I do not see how this conveys any more intuition. How does it relate to "real work"? – Steven Gubkin Aug 31 '14 at 20:46
The most important calculation in all of complex analysis is the following:
$$ \int_C \frac{1}{z}dz = 2\pi i $$
Where $C$ is the unit circle centered at the origin. Let's see if we can understand this integral geometrically. Hopefully this will illuminate the general meaning of the complex integral as well.
Cut the unit circle up into a million tiny directed line segments (all pointed in the "positive" direction). Each one of these is a small change in $z$ along the curve: each one of these is a little "$dz$". The directed line segment from the origin to that point on the unit circle is $z$. For points on the unit circle, $\frac{1}{z} = \overline{z}$ is the reflection of $z$ in the real axis. Remember that complex numbers multiply by multiplying the moduli and summing the arguments. Since if the argument of $z$ is $\theta$, then the argument of $dz$ is $\frac{pi}{2}+\theta$ by geometry (radius is perpendicular to tangent of a circle), and the argument of $\frac{1}{z}$ is $-\theta$. So the argument of $\frac{1}{z}dz$ is $\frac{\pi}{2}$! Also since $|z|=1$, $|\frac{1}{z}dz|=|dz| = ds$, the length of the little line segment. Thus $\frac{1}{z}dz$ is a little line segment of length $ds$ pointing straight up, where $ds$ is the length of a little arc of the circle. In other words, $\frac{1}{z}dz = i ds$ Summing all of these around the unit circle we get $2\pi i$.
Hopefully this picture helps you to visualize all of this:

Think of it as separately tallying the real and imaginary parts of the function. That is, the path integral
$$ S=\int_C f(z) dz $$ could be written as a sum $S=R+iI$ of the real and imaginary parts $$ R=\int_C \Re[f(z)] dz $$ and $$ I=\int_C \Im[f(z)] dz $$
This works for $n$-dimensional coordinate integration as well, where you are separately tallying each coordinate of the vector-valued function $f$, though by the time you get there you are well on your way to connections on manifolds and the cliffs of insanity.

We develop an efficient estimation procedure for identifying and estimating the central subspace. Using a new way of parameterization, we convert the problem of identifying the central subspace to the problem of estimating a finite dimensional parameter in a semiparametric model. This conversion allows us to derive an efficient estimator which reaches the optimal semiparametric efficiency bound. The resulting efficient estimator can exhaustively estimate the central subspace without imposing any distributional assumptions. Our proposed efficient estimation also provides a possibility for making inference of parameters that uniquely identify the central subspace. We conduct simulation studies and a real data analysis to demonstrate the finite sample performance in comparison with several existing methods.

'my.organization.MyActivity.myProperty' # private property, prefixed with activity name to avoid name clashes
Due to bug #4662 only some known properties are retained! The list is at the bottom of datastore/ (fixed in Sugar 0.83)
And custom properties must have String values for now (bug #5134).
And since Sugar 0.83 all former String values are now stored and returned as Arrays of Bytes. You can still set them as Strings.
Keeping and Resuming
To create an item in the datastore, call create():
object_id = datastore.create(properties, filename, transfer_ownership)
The metadata properties are a dictionary (type "a{sv}") containing (at least) the entries mentioned above. If filename is not empty, the file will be moved or copied to the datastore, depending on the transfer_ownership flag. The activity should delete the file once the call completes (if transfer_ownership was false). Otherwise (if transfer_ownership was true) the datastore will remove the file. For this to work under rainbow you must place the file in the "instance" directory. The returned id will be a string like '4543af91-7be9-404e-b2f1-3e27cb15a15d'.
To update an item use update():
datastore.update(object_id, properties, filename, transfer_ownership)
Again, if a filename was given and transfer_ownership is false, the activity is responsible for deleting the file after the call returns.
To retrieve an object's properties and file:
properties = datastore.get_properties(object_id)
filename = datastore.get_filename(object_id)
The returned temp file should be deleted by the activity as soon as possible, latest when the activity quits.
The metadata properties need to be preserved and stored again when updating an entry. An activity should also track updates to the properties made in the Journal while editing the datastore object. For this it should subscribe to the Updated signal:
An efficient way to do this is registering a DBus match like path='/org/laptop/sugar/DataStore', member='Updated', interface='org.laptop.sugar.DataStore', type='signal', arg0='objectId' --Bert
Activities may query the datastore:
(results,count) = datastore.find(query)
It returns the results as array of properties and a count of matching items (the array may have fewer items if the query was limited). In addition to the usual metadata items, the properties will include the object id at key 'uid', the mountpoint of the item at key'mountpoint', and possibly a 'filename' if requested.
The query can be a:
string: fulltext search
the given string is searched in all text properties
dictionary: structured query
the key-value pairs in the dictionary specify the value (or array of values, or dictionary specifying range) for a specific property, e.g.:
'title' = 'First Project' (but see note below)
'mime_type' = ['image/png', 'image/jpeg']
'mtime' = {'start' = '2007-07-01T00:00:00', 'end' = '2007-08-01T00:00:00'}
also, there are a few specific keys to adjust the query:
'query': fulltext search term
'order_by': key (or array of keys) to order results by, to reverse order use '-key' (but see note below)
'limit', 'offset': return only limit results starting at offset
'mountpoints': array of mountpoint ids to search (or all if not specified)
'include_files': if true, generate files as if get_filename() had been called for each item. In results, a property 'filename' will be added.
NOTE: Since Sugar 0.84 only very few keys are supported ('uid', 'activity', 'activity_id','mime_type', and 'keep', see here). Other keys are ignored so you may get back more results than expected. Results are ordered by timestamp by default. Sort keys are limited, too (none in 0.84, in 0.86 'timestamp' and 'title', see here).
You can also retrieve an array of unique values for a field:
values = datastore.get_uniquevaluesfor(property, query)
Note that currently (2007-07-25) the query is ignored in this call, it looks for all values in all entries.
Progress Display
To add a progress bar to a Journal entry (like the Browse activity does while downloading files), create an entry with a "progress" property in the meta data. The value is the percentage done (0 to 100). The file cannot actually be stored incrementally in the datastore, it needs to be saved to a temp file first. But the entry metadata can be updated continuously to inform the user of progress while creating the temp file (by not giving a filename yet in the update() call). Once the temp file is complete, it can be checked-in as usual. The user can cancel by clicking the x icon next to the progress bar. This deletes the entry, so you need to watch for the datastore's "Deleted(id)" signal.
meta =... # regular metadata
meta["progress"] = 0
id = datastore.create(meta, "") # create with progress bar
while (done() < 100) {
 if (got_signal(datastore, "Deleted", id))
 return user_cancelled();
 meta['progress'] = done()
 datastore.update(id, meta, "") # update progress bar
datastore.update(id, meta, # check-in file, remove progress bar
Journal UI
The Journal activity provides a D-Bus service to allow activities to bring up an object chooser dialog, focus searches etc.:
Service name: org.laptop.Journal
Object path: /org/laptop/Journal
Interface: org.laptop.Journal
Choosing Objects
Call this method to bring up the Chooser dialog (which looks like a small journal overlayed on your activity):
chooser_id = org.laptop.Journal.ChooseObject(xid, what_filter)
The xid should be your activity's X window handle, or 0. The filter says what type of Journal entries is preselected in the drop-down menu (this parameter was added in Sugar 0.83). It's a string containing either a bundle id (e.g.,'my.organization.MyActivity'), or one of the generic data types ('Text', 'Image', 'Video', 'Audio', 'Link' definition), or an empty string for no filter. The call returns immediately with a string chooser_id. You need to watch these signals which get emitted when an item is chosen or the dialog is canceled:
ObjectChooserResponse(chooser_id, object_id)
The object_id received in an ObjectChooserResponse signal then can be used to open the corresponding datastore object.
Focusing Objects
The Journal activity allows an activitiy to "focus" an object, so the user can immediately open it (this is currently the only way to have one activity "launch" a different activity).
Switches to the Journal activity and shows the selected object.
This can be used to, e.g., open a URL (create a URL object in the journal then call this) or to view source code (store the source code as text file in the journal then call ShowObject() on it).
To focus on multiple objects: org.laptop.Journal.FocusSearch(query) Removed in Sugar 0.83
Mount Points
Devices are represented as mount points in the datastore. If no mountpoint is explicitly specified, the main datastore (Journal) is used.
 mounts = datastore.mounts()
Returns an array of mount point descriptors where each descriptor is a dictionary containing at least the following keys:
'id': the id used to refer explicitly to the mount point
'title': Human readable identifier for the mountpoint
'uri': The uri which triggered the mount
Mount points can be specified when creating an object (using a'mountpoint' key and id value in the properties), and when querying the datastore (by adding a'mountpoints' query option).
Large files to be stored on an external device should be placed at the uri of the mount point (see external media).
Activities are isolated from each other and from the "olpc" user. They do not have the same permissions as you would expect in a non-restricted Linux environment (see Bitfrost and Rainbow). In particular, they can not write in the /home/olpc directory!
Users and Groups
While Sugar runs as user "olpc", activities do not (the Terminal activity as a maintenance tool is an exception).
Instead, each activity instance is run with a unique user id. That is, a new anonymous user is created when the user clicks an activity icon, and the Rainbow demon runs the activity under that user.
All instance of the same activity get the same unique group id. That is, a new anonymous group is created when the activity is run for the first time,

text: A numerical simulation code was developed for estimating the surface temperature of POM wear test with different shapes. By using the developed code, the effect of sliding geometry with various contact areas on the surface temperature was numerically investigated. The simulation results show that the limiting sliding velocity depends on contact area and reaches a peak value at a certain geometry. It was also found that the simulation code leads an exact prediction of limiting velocity in the range of small contact area. This is important since the exact temperature measurement is very difficult in this range.

I'm writing an application which must log information pretty frequently, say, twice in a second. I wish to save the information to an sqlite database, however I don't mind to commit changes to the disk once every ten minutes.
Executing my queries when using a file-database takes to long, and makes the computer lag.
An optional solution is to use an in-memory database (it will fit, no worries), and synchronize it to the disk from time to time,
Is it possible? Is there a better way to achieve that (can you tell sqlite to commit to disk only after X queries?).
Can I solve this with Qt's SQL wrapper?

Let's assume you have an on-disk database called 'disk_logs' with a table called 'events'. You could attach an in-memory database to your existing database:
ATTACH DATABASE ':memory:' AS mem_logs;
Create a table in that database (which would be entirely in-memory) to receive the incoming log events:
CREATE TABLE mem_logs.events(a, b, c);
Then transfer the data from the in-memory table to the on-disk table during application downtime:
INSERT INTO disk_logs.events SELECT * FROM mem_logs.events;
And then delete the contents of the existing in-memory table. Repeat.
This is pretty complicated though... If your records span multiple tables and are linked together with foreign keys, it might be a pain to keep these in sync as you copy from an in-memory tables to on-disk tables.
Before attempting something (uncomfortably over-engineered) like this, I'd also suggest trying to make SQLite go as fast as possible. SQLite should be able to easily handly > 50K record inserts per second. A few log entries twice a second should not cause significant slowdown.
share|improve this answer
If you're executing each insert within it's own transaction - that could be a significant contributor to the slow-downs you're seeing. Perhaps you could:
 - Count the number of records inserted so far
 - Begin a transaction
 - Insert your record
 - Increment count
 - Commit/end transaction when N records have been inserted
 - Repeat
The downside is that if the system crashes during that period you risk loosing the un-committed records (but if you were willing to use an in-memory database, than it sounds like you're OK with that risk).
share|improve this answer
A brief search of the SQLite documentation turned up nothing useful (it wasn't likely and I didn't expect it).
Why not use a background thread that wakes up every 10 minutes, copies all of the log rows from the in-memory database to the external database (and deletes them from the in-memory database). When your program is ready to end, wake up the background thread one last time to save the last logs, then close all of the connections.
share|improve this answer
Because then I need to create the logs, remember which part of the log I already saved, maintain the background thread, and largely speaking implement synchronization myself. That's possible, but I want to avoid that. – Elazar Leibovich Jun 22 '10 at 20:31

Inspection Control - Focus on Stamp Warranty
After completing this course, the student should be familiar with the basics and importance of the stamp warranty inspection control. The student should completely understand the procedures required for implementing and maintaining an inspection control program with a stamp warranty focus.
Why Learn about Stamp Warranty?
Aerospace projects consist of complex systems of interdependent components. To ensure that the entire system works properly, it is of utmost importance that all of its components are functional and integrated seamlessly. To guarantee this, it is necessary that the system and its components be inspected at different points throughout the project life. Inspection control and the uses of stamps allows you to keep track of the inspections that different components of the system have undergone. While this course describes the methods used by NASA, for academic payload projects you could adopt simpler versions of the inspection control procedures. The main purpose of proof of inspection is still valid for your project.

text: Background: The production of triterpenes from plants for pharmacological purposes varies in concentration, due to genetic and environmental factors. In vitro culture enables the control and increase of these bioactive molecules. Objective: To evaluate the effect of plant growth regulators and elicitors in the induction of calli and the production of ursolic acid (UA) and oleanolic acid (OA) in Lepechinia caulescens. Materials and Methods: Leaf explants were exposed for the induction of calli at different concentrations and combinations of 2,4-dichlorophenoxyacetic acid (2,4-D) and 6-benzylaminopurine (BAP). Methyl jasmonate (MJ) and salicylic acid were used as elicitors. High-performance liquid chromatography method was used to quantify UA and OA content in each treatment. Results: Treatment with 3.0 mg/L of 2,4-D and 0.1 mg/L of BAP produced the best results for calli induction and production of UA (1.57 mg/g dry weight [DW]) and OA (1.13 mg/g DW). Both elicitors facilitated the accumulation of triterpenes. Conclusion: The combination of auxins and cytokinins showed favorable results for the induction of calli. Variation concerning the accumulation of UA and OA was observed between treatments. MJ increased the production of triterpenes five times after 8 h of exposure, compared to control treatment. There is a greater accumulation of UA (16.58 mg/g DW) and OA (1.94 mg/g DW) in leaves of wild plants.


Recently Microsoft support has fielded inquiries from several customers asking how to troubleshoot problems that cause delays during the boot and user logon processes on a desktop or laptop. The Windows Performance Toolkit xbootmgr.exe tool works well for troubleshooting boot and startup issues on a single machine. (See "Diagnose Shutdown Problems with Xbootmgr" for more information about using xbootmgr.exe.) But what if you're a large enterprise with thousands of desktops? You need a way to identify problem machines before a user reports them to the Help desk. You need to monitor desktop startup times over time and across the enterprise. And you need a way to collect boot time measurements, similar to those collected by xbootmgr.exe, from every machine for every boot. Here, I'll explain how you can use an event log, the new Windows 7 Event Viewer, and the Wevtutil tool to do these things.
A New Event Log to Aid in Troubleshooting
Beginning with Windows Vista, Windows now includes a new category of event logs: Applications and Services logs. The infrastructure underlying event logging now conforms to an XML schema. You can easily access the XML data for any event. The new event log interface lets you construct XML-based queries against event logs. The Event Viewer gives you to access to the new XML functionality in an easy-to-use graphical interface.
One of the logs in this new category is the Diagnostics-Performance/Operational log. This log contains events that record performance measurements similar to those provided by xbootmgr.exe. In fact, the data recorded is generated by the same mechanisms that Xbootmgr uses. Event IDs 100 through 110 record boot and startup performance statistics.
Using the Event Viewer in Windows 7
The new Event Viewer in Windows 7 lets you do more powerful filtering. The new UI lets you specify ranges of events. Under the covers, it builds the XPath query to filter out the events based on the criteria you specify. Figure 1 shows how you can filter for events 100 through 110. Figure 2 shows the XML version of the same query parameters. We're interested in Event ID 100 for the purposes of measuring the boot performance. Figure 3 and Figure 4 show the normal and XML views for event 100.
The XML presentation of the event contains a lot of interesting information. The BootTime value represents the number of milliseconds that elapsed from the time the system booted to the point after the user logged in that the system reached 80 percent idle for 10 seconds. The other time values listed represent the elapsed time for various stages during this boot process. You can find more information about the stages of the boot process in the Windows On/Off Transition Performance Analysis white paper.
The other boot performance events record information about specific events that contributed to delays during the boot/startup sequence. The trick is how to know which boot instance these messages belong to. This is where the ActivityID come in handy. In Figure 4, you'll see the following in the XML data:
All events related to this boot instance in this Event 100 record have this same ActivityID. By performing the following steps, we can use this information to create a more complex filter:
1. Click Filter Current Log… in the Actions Pane of Event Viewer.
2. On the XML tab, check the box Edit query manually, then answer Yes when prompted to continue.
3. Enter the following XML text into the query box:
4. Click OK.
Figure 5 shows a total of three events for this ActivityID. We can now examine these events to understand the problems that contributed to any boot/startup delays.
Collecting Data with Wevtutil
So far we've looked at only one boot instance. How do we collect data for all boot instances? By using Wevtutil, a Windows command-line tool for querying the Event logs. Using the following example, you can extract all the Event ID 100 records from the event log on a system:
wevtutil qe Microsoft-Windows-Diagnostics-Performance/Operational /rd:true /f:xml /q:"*\\[System\\[(EventID = 100)\\]\\]" /e:Events > boot.xml
This creates an XML data file that contains all instances of the boot performance event for a machine. With each ActivityID, you could then query for the other related events. For example, the following query extracts the same three event records we saw in Figure 5:
wevtutil qe Microsoft-Windows-Diagnostics-Performance/Operational /rd:true /f:xml /q:"* \\[System\\[(Correlation\\[_USER_='\\{00000001-0000-0000-1020-5CA87BB1CA01\\}'\\])\\]\\]" /e:Events > bootrelated.xml
Wevtutil.exe has many more options. Run the utility without any parameters to see a list of available options. For more information, see the MSDN article "Event Queries and Event XML." And for more information about learning XPath to define event queries, see XPath Syntax and XPath Examples.
Putting It All Together
Once you have the event data in XML format, it's fairly easy to extract the most interesting data points. Figure 6 shows some sample data I collected from one machine. In this example, I converted the time values to seconds. Differences in the number of applications that start at boot time could be significant when you're investigating changes in performance. With historical data like this, you can now begin to do some trend analysis. For example, this system was built on 1/13/2010. Application installations and configuration changes continued over the next couple of days. By 1/21/2010 the configuration changes had been completed. After that, the BootTime value was averaging about 124 seconds. However, notice that on 2/4/2010 and 2/9/2010 the times were significantly longer than average.
Extending the Value
Now that we have an automated way to extract the event data in XML form, we can collect this data periodically from multiple computers and store the results in a database. Using some simple reporting, it's easy to do trend analysis. A complete enterprise solution will require more code development and data management, but it's feasible. And that's exactly what one of my largest customers did.
Using a VBScript program I wrote, the customer collects event data into a SQL Server database. They've used this data to establish some baseline statistics for their desktop image build. They can pivot this data based on the hardware (e.g., memory, CPU, model) and software configuration. Using SQL Server Reporting Services, the customer built a dashboard view that displays the boot-time health status of all desktops in the enterprise. With specific reports, they can compare this baseline to new data collected after deploying new group policies, new security tools, or a hardware upgrade. They also use this data to proactively identify machines that take longer than the average baseline. This information allows IT to address issues before users call the Help desk, reducing the time to resolution and making end users happier.

To avoid image piracy risks, the exposure to image URLs must be restricted so that only thumbnailed or watermarked images can be obtained. To do this, you can enable source image protection.
After enabling the source image protection, you cannot access images in the following two ways:
- Access directly with an OSS address:
- Request thumbnails with processing parameters:
You can only access images in style mode:
- Access through URL parameters
- Access through separators
- The preceding rules only apply to anonymous accesses to public-read files. After enabling the source image protection, you can obtain source images using a signature-based method.
- The source image protection is designed for protecting image files, and the suffixes of the image files to be protected must be set. For example, if.jpg files are set for source image protection, you can still directly access the source images of.png files.
You can configure the access rules in the Image Processing module of the bucket in the console. Access rules
