EPDM foam for hard-shell case?

Huckle Asks: EPDM foam for hard-shell case?
I need to fly with some delicate and slightly heavy equipment that is going to have to be checked in. I have hard-sided cases I can put it in that came with convoluted open cell foam. Given the weight, I’d like to put a sturdier foam in, as I’ve seen the equipment shift in the convoluted foam just from regular day-to-day travel. I assume the airline baggage handlers will drop-kick it.

Polyethylene foam seems like the popular option for custom cut case foam, but while looking at the selection at the local hardware store website I saw they also have closed cell EPDM (ethylene propylene diene monomer) foam, which is much cheaper.

Has anyone attempted to cut/glue EPDM before? Does it work well as a case foam?

David Asks: HVAC motor wire help
I’m without heat and need some quick help. I had my hvac blower motor (16 years old) burn up from the intake being blocked. I got a replacement but it has a difference in wiring. The original has the 2 brown capacitor wires, the green ground, then harnesses a red, yellow, and black. The new one has the brown capacitor wires, green ground, and then a black and white. It also has a set of purple and yellows that dictate direction. How can I wire the new one into my system. Thank you in advance.

Magdalena Asks: Covariate selection for double robust estimations
I would like to combine a matching technique and a regression analysis. I have a binary treatment and several covariates.

As I understand, I can either A) use the same covariates in the matching and the regression analysis or B) include only covariates describing the selection into treatment mechanism in the matching and add further covariates (describing the outcome mechanism) in the outcome model I estimate afterward.

Do I understand this correctly? If yes, how do I decide on one of the two options, and which papers discuss this issue?

Fatal error uncaught imagickexception unabletoopenblob

I downloaded ImageMagick and GhostScript to run a php program that converts a pdf file into an image file such as jpg on a Windows 10 Pro PC as a home server with xampp.

The steps are as shown in GitHub repository I did it.

Error message

The output from phpinfo (); confirms that imagick is enabled.
Actually using imagick, even if you read pdf and jpg files using readImg and other functions, you can also use file_get_contents (‘image file path (full path and relative path tried)’) Reading the output just returns the following error, for example:

GitHub repositories also indicated «reflecting» Yes, I think it’s a problem with ImageMagick’s version.

If it is VC15, it seems that ImageMagick less than version 7 has not been released, and it cannot be downgraded.

Please lend someone wisdom. Thank you.

1. Below is a copy of README.md in the GitHub repository. 2.Usage environment, software

Windows 10 Pro
･ xampp (PHP 7.2.12) (Control Panel version is v3.2.2)
･ ImageMagick-7.0 .7-11-vc15-x86
･ php_imagick-3.4.3-7.2-ts-vc15-x86
･ Ghostscript 9.26 for Windows (32 bit) AGPL licence
･ Microsoft Word 2016

3.Experiment and results

Experiment date: 2018/11/25

3-1-1.Experiment 1 Terminal server development [1]

①Installed XAMPP according to the reference site [1].
However, all software was selected and installed.
The directory where xampp is installed is c: xampp .
② Accessed http: // localhost /.

3-1-2.Result of Experiment 1

A page similar to Figure 3-1-2 is displayed.
Figure 3-1-2
Figure 3-1-2 Results of Experiment 1

3-2-1 Experiment 2 Confirmation of expansion module

①Created the following file test.php [2] and copied it to C: xampp htdocs . Copying to this directory is equivalent to uploading to the server.

② A text hoge.pdf written only as «hoge.pdf» in Microsoft Word 2016 was created and copied to C: xampp htdocs .
(3) The test.php uploaded to the server was viewed with a WWW browser.

3-2-2.Experiment 2 results

As a result of Experiment 2, Fatal error was displayed as follows.

This indicates that the server created by xampp does not have a class called Imageck, that is, ImageMagick is not installed.

3-3-1.Experiment 3 Enable ImageMagick [2]

①Create the following isTs.php [3], copy it to c: xampp htdocs , access http : //localhost/isTs.php,
･ Confirmed php version.
-Confirmed the Compiler version.
• Confirmed Architecture.
-Checked whether thread safe is enabled.

② I installed GhostScript in C: xampp gs gs9.26 .
(3) Accessed the official download page of ImageMagick and downloaded ImageMagick-7.0.7-11-vc15-x86.zip.
This is because vc15 is the version of the php compiler included in xampp, and x86 is that all software included in xampp runs on 32 bits. (Please check Table 3-3-3-1)
Then expanded and copied the entire contents to c: xampp ImageMagick .
④ Go to the official download page of Imagick, select the 3.4.3 directory, and search for php_imagick-3.4.3-7.2-ts-vc15-x86.zip .
7.2 means php version is 7.2.n, ts means thread safe is enabled, vc15 means compiler version, x86 means 32 bit.
If i do not select the correct zip file corresponding to Table 3-3-1, you will not be able to experiment properly.
php_imagick-3.4.3-7.2-ts-vc15-x86.zip did not exist on the download page shown in the reference site [2]. However, it was on another page [4], so I downloaded it.
After extraction, copy php_imagick.dll to C: xampp php ext ,
All files starting with CORE_RL _ were copied over to C: xampp ImageMagick bin .
⑤ C: xampp php php.ini

, so I added extension = php_imagick.dll there.
⑥ Environment variables were specified as shown in Fig. 3-3-1.

Figure 3-3-1 Setting environment variables

3-3-2.Result of Experiment 3

As a result of (1), we found out that Table 3-3-3-1.

Table 3-3-2-1 Installed php specifications

After to were accessed http: //localhost/isTs.php , it was not displayed in step ①. (Please look at the repository).

This means that the ImageMagick module has been successfully loaded.

And when http: //localhost/test.php is accessed,

is displayed, and the error content is different from that in Experiment 2.
This confirmed that the php program itself had to be rewritten, but that the module itself was working.

3-4 Experiment 4 Reading php file and its result

I moved ImageMagick with php and looked for code in the php program that could read pdf files.
However, no matter what function was used to read the pdf or jpg file, reading the output of file_get_contents () only returned an error.

4. Reflections

According to the reference site [5] [6], if you download ImageMagick, you need to compile it with an appropriate method to create a file called configure.exe, and it is not possible with ImageMagick7 installed this time, and it is done with version 6 It seems to have to be.
Next time I try again, I will install ImageMagick6.
However, this change will make the situation even worse and not recoverable. C: xampp ImageMagick on GitHub and make it public.

I want to see if I can access the file from php,
A request was made to add/modify questions.

I want you to check two things.

One,
Whether the file can be opened from php.
For example, using PHP: fopen-Manual.
If a file name consisting of simple alphanumeric characters can be opened at this time,
It can be confirmed that it is not a problem related to access rights.

Another one,
The file name of the uploaded file
Output to a temporary text file,
Check what encoding it is.
File name encoding is SJIS
If php internal encoding is UTF-8,
Since filenames may not be handled properly,
As a precaution, try to manage using PHP: mb_convert_encoding-Manual.

php_imagick.dll is version 5.4.20.0, downloaded from http://pecl.php.net/package/imagick/3.1.2/windows, latest stable TS version for PHP 5.4 (I’m running Apache 2.2.26 on Windows, via php5_module).

Dependencies were downloaded from http://windows.php.net/downloads/pecl/d … c9-x86.zip

I don’t know if I can upgrade it to ImageMagick-6.8.9-1 because it looks they are compiled with VC10 and I’m afraid they can be not compatible.

I tried before to run ImageMagick-6.8.9-1 as «external», but there was no way to make Piwigo «see» it.

Also, I was running before Menalto Gallery 2 with ImageMagick and had no problem. Now I’m trying to switch to Piwigo but it looks ImageMagick support is somewhat not yet ready, especially in Windows.

The steps are as shown in GitHub repository I did it.
