Hi folks, I am pleased to announce that Mike Milner and I have finished the Ruport Book. We have published it under our own company (Rinara Press LLC) through Lulu. With the help of the Ruport community, we''ve refined the book over the last few weeks to meet the needs of our users. We think it will be a great help to anyone trying to learn how to do reporting in Ruby / Rails using

Hello all, My statistical analysis training up until this point has been entirely done in SAS. The code I frequently used was: *Yield Champagin; data yield; set stress; if field='YV' then delete; if field='HB' then delete; if barcode='16187DD4015' then delete; if barcode='16187DD6002' then delete; if barcode='16187DD2007' then delete; if

Hi, I have two objects: Contacts Lists I want to be able to add multiple contacts to multiple lists. I''ve created a linking table and a form that allows me to select the contacts using checkboxes, but I''m having some problems with the controller and model. I receive the following error message when I submit the form: Mysql::Error: Cannot add or update a child row: a

Regarding point 3, as a moderator I have been helping Andrew get this post out to the list over the past week. His previous attempts were encoded in some way that the listserv rejected. He sent me the post via his gmail account and viewing the source I saw it had at least both plain test and HTML an I said it was worth a try to post it. Certainly on my mail client his post displays acceptably

So I would like to be able to update a record without having to load the edit page. Lets use checking out a book as an example. From the front page of my application I would like to be able to have a form field where I can enter a record id and select one of a couple of check boxes and then hit submit which will update the associated record with the action selected by the check box (check out,

I''m trying to stub(!) the Kernel.` (backquote) method and I''m having confusing (to me) results. Here''s the method I''m spec''ing: class Barcode ... def raw_barcodes self.make_temporary_copy `OcrBarcode #{self.temp_file_path}` end ... end And this is my (newbish) attempt at the spec: describe "Calling @barcode.raw_barcodes" do

You might get better answers if you 1 - break this down into separate issues 2 - tell us what you want to achieve in words rather than SAS, we all read English but few of us speak SAS 3 - post in plain text not HTML as HTML mangles your post On 29/09/2017 13:47, Andrew Harmon wrote: > Hello all, > > My statistical analysis training up until this point has been entirely done > in

I will offer an opinion, with which others may fairly take issue. If you are coming from SAS and wish to learn R, you should forget about SAS entirely; it is ancient and convoluted. But more to the point, as others have already suggested, you will only confuse and hamstring yourself trying to convert the programming paradigms of one language into another. Better to consider the **tasks** you wish

Hi, https://ctan.org/tex-archive/graphics/pstricks/contrib/pst-barcode/ says that pst-barcode is included in texlive. I installed texlive, and it can?t find pst-barcode.sty. Is that a bug in the packaging Centos does, or is texlive in Centos some derelict version?

Hey, I'm trying to match patient identifiers from two separate input files, and then add information from one of the input files to the corresponding output file. I'd greatly appreciate any help! More specifically, Input_File_1 has a column header "bcr_patient_barcode" Input_File_2 has a column header "Barcode" and a column header "Batch" I want my script

Hi, folks, I'm about to go googling, but thought I'd ask here if anyone's using a barcode scanner with CentOS, and if so, a) what scanner are you using, and b) what, if any, software are you using to record what it scans? <mutter, mutter, the serial number of every bloody h/d that we're asking them to deGauss...mutter,mutter> mark

One my of my CDs has a bar code, 4 011222 044068, which is titled "EAN CODE". Another one simply has a barcode, 07822-18646-2, without any title. Should I assume that the barcode of any CD is the EAN code? I'm asking this because I want to know how to title the comment of the Vorbis file -- "EAN code" or "Barcode". Thanks. -------------- next part

Hi guys, Given a page that retrieves data from a 3rd party API, how would you then go about associating additional info in the application''s database with that record? Specifically, the page displays info on a product, and I''d like to store and display locally created reviews for that product. To display the product I''m using a route of the form /product/

Hello Rubyists, I need to generate barcodes (in UPC and codabar symbologies) and would like to know if anyone has done this with Ruby. From what I can tell, it would be possible to use the gnu-barcode [1] or barcodewriter [2] to generate a PostScript, then through RMagick (via GhostScript) take the file and create a GIF/JPG. These will really only be used for web display (to be printed

I am fairly new to R and I am writing a script that would take a file, as an input, and generates a bunch of graphs out of it. My first task is to be sure that the file is of the right type by looking if there is a valid barcode in it as in (the barcode is beetween a double and single underscore): library(tkWidgets) ############## #Loading a file #testing if valid if not kill the execution

We use the debian 4.0 Linux with the wine 1.0. When we run our application on this platform, there is a problem: The Barcode can't be displayed correctly, but occurs some Garbled. The font we use is ?Carolinabar-B39-25F2?. But when we install the wine-0.9.25 instead of wine-1.0, the barcode can be displayed correctly. So could someone tell us the reason, and gives us some suggestions?

One of our summer interns has stayed on during the school year to work some weekends on special assignments. This past weekend, her assignment was to draft, and try out, procedures for scanning all incoming regular mail including the envelopes. This is a new effort for us because previous mail handling was done by another organization. Most of our incoming mail is from other businesses that
