Is there a way to read the free baggage for a given flight without calling WP before calling
wp*bag
If a WP is stored as a PQ it can be read from there.
If it's a ticketed PNR, the baggage allowance is on the e-ticket. It can be viewed with command WETR*2/E - Where "2" is the line number of the ticket in *T field.

Rookie S3 user here looking to troubleshoot a problem I encountered while helping some friends with their business. Their business revolves around selling courses and the program they use is WooCommerce and they attach course files through WordPress. The way these courses work is that there is a live video call where people like to join in so the product on WooCommerce initially holds the details for the upcoming call and afterward additional audio and transcripts are added to the product for sale. The problem is that this means people who had bought the course prior to this call would not receive these files unless permission to see them was manually given. As this is redundant and troublesome, my thought was to change the purchase to instead give a link which goes into an Amazon S3 bucket labeled courses and give them access to a specific folder within it. Ideally, this link would let them see new files lives and furthermore would limit the size of data on the website which is hosted on a dedicated server (save some $$$ on hosting fees, 2 birds 1 stone) The problem however is that since I am a complete novice to this style of coding, I am unsure of how to do this although I do think it is possible given an answer is already out there or if I can bull and jam my way through a section of code. The reason I am looking to sort out courses as folders inside a bucket instead of individual buckets is that the number of courses the website currently has is nearing 200 and if an effort was made to change those then it would be well over the 100 bucket limit in addition to being an exercise in repetition. Any advice or help would be greatly appreciated, thanks!
If I understand you correctly, you want to host content on S3, but want to achieve some degree of access control on that content.
The most straightforward way to do this, the one that involves minimal S3 integration, is to presign an S3 url for the user. the presigned url would be good for a limited time and could be generated directly before redirecting the user to that URL by your wordpress site, which would in turn hold aws access credentials.
https://docs.amazonaws.cn/zh_cn/aws-sdk-php/guide/latest/service/s3-presigned-url.html eplains more about this from a php perspective, which I'm guessing is the right lens for you.
This allows some modicum of access control ( the users can still share the document after they've accessed it, but at least it's not just public).
If you don't need access control, you can make the s3 object public and omit the signing altogether.
I want to create a smart contract and launch it for ICO. I also create a website where people can buy my token. I want know how to check how many token been sold (live)? so i can create a live bar counter to show how many percentages of the token already been sold.
Or is there a way i can monitor the token sale process in the smart contract?
A token contract is no different than any other smart contract. There are no special built in Solidity features or logic associated with them. They are just regular smart contracts that follow a specification.
So, if you want access to the number of tokens sold, you code that into your contract. While tokens sold is not part of the standard ERC20/ERC721 interface, nothing prevents you from adding a constant function to retrieve this information. In fact, if you're using the basic Zeppelin Crowdsale contract, you can just calculate it using the public state variables weiRaised / rate (Chances are you should be creating your own Crowdsale subcontract, so it's better to add the functionality you want there).
We can use the Etherscan Developer API to review transactions against a given contract address and find out the total supply or number of items available for sale.
There is a lot you can do with the Etherscan Developer API. For example, here's one URL that pulls data from Ethereum Mainnet -> Etherscan -> JSON parser -> Shields.io and renders it as an image to calculate the number of Su Squares remaining for sale:
Source: https://img.shields.io/badge/dynamic/json.svg?label=Su+Squares+available&url=https%3A%2F%2Fapi.etherscan.io%2Fapi%3Fmodule%3Daccount%26action%3Dtokenbalance%26contractaddress%3D0xE9e3F9cfc1A64DFca53614a0182CFAD56c10624F%26address%3D0xE9e3F9cfc1A64DFca53614a0182CFAD56c10624F%26tag%3Dlatest%26apikey%3DYourApiKeyToken&query=%24.result
^ I don't know if SO is going to cache the image here. But that URL is a live URL which pulls the number of Su Squares available hot off the blockchain.
I read some rss feed from my application, and as some articles can be updated on the site, I wanted to know if there is a field I can look at, in order to see if I'm getting the same article or a modified version.
I know there's a ttl field, but it is just an hint of how long I can keep the article in the cache: it doesn't actually say if it was really updated or not.
As long as you don't mean something like the cloud element there isn't any.
"Its purpose is to allow processes to register with a cloud to be notified of updates to the channel, implementing a lightweight publish-subscribe protocol for RSS feeds."
See the list of elements at w3.org.
If an User has X amount of credits on his account (I think CCK can store this value). He can create specific Nodes (requests for admin). Each Node has a Type (Taxonomy defined, may be. Or via CCK). Each Type has associated number of credits. When user publishes a Node providing certain type, his balance of credits decreases by the number of credits Node Type has (admin will perform this request and send user notification email).
This is some kind of very simple e-shop for activation codes. I didn't want to use Ubercart due to it's complexity. May be this functionality can be achieved using some simple Drupal modules? Or may be there are some alternate ways? Or it is better to go Ubercart (can it do what I want BTW)?
I've seen folks in the Ubercart forums do this kind of thing for purchasing/posting ads on a site.
Check out these modules:
http://drupal.org/project/uc_store_credit
http://drupal.org/project/userpoints_ubercart
https://www.drupal.org/sandbox/taggartj/2343093
may be worth a look it is a credit system, adds a product feature to give user credits also has good helper functions to integrate with rules ect , also has a sub module to limit a content type by amount of credits and then deducts after the new node has ben created & has blocks to show the user their credits and credit history :)
Quick question:
When I'm in Google Reader, it will flash and pop up a new number of unread items indicating that a new article has just been published (typically <1 minute after the blog's "published date"). Does Google just constantly ping every blog I'm subscribed to, or does the RSS standard have some sort of "signal" that it puts out to subscribing agents when new content it put up?
Thanks for any clarification!
I'm currently running an app that is based on RSS feeds, but I have a cron job running hourly to scour the interwebs for new content, but I'd love to know more about how to solve the "I need realtime" problem without overstaying my API call welcome.
" Does Google just constantly ping every blog I'm subscribed to"
Yes.
"does the RSS standard have some sort of "signal" that it puts out"
No.
If you want real time information, contact the vendor and pay them to send you stuff. Seriously. If information has value, then timely information has more value. If you want it sooner, you have to pay to get it before the folks who are getting it for free.
