Crunch | Insane PNG image optimization | Compression library

kandi X-RAY | Crunch Summary
Crunch is a tool for lossy PNG image file optimization. It combines selective bit depth, color type, and color palette reduction with zopfli DEFLATE compression algorithm encoding using the pngquant and zopflipng PNG optimization tools. This approach leads to a significant file size gain relative to lossless approaches at the expense of a relatively modest decrease in image quality (see example images below). Continuous benchmark testing is available on Travis CI (open the Benchmarks build for the commit of interest). Please see the benchmarks directory of this repository for details about the benchmarking approach and instructions on how to execute benchmarks locally on the reference images distributed in this repository or with your own image files.

QUESTION
I am crunching large amounts of data without a hitch until I added more data. The results are written to file as strings, but I received this error message and I am unable to find programming error after combing my codes for 2 days; my codes have been working fine before new data were added.
...ANSWER
Answered 2021-Jun-15 at 07:04First of all: a Rat with a denominator of 0 is a perfectly legal Rational value. So creating a Rat with a 0 denominator will not throw an exception on creation.
I see two issues really:
- how do you represent a
Ratwith a denominator of0as a string? - how do you want your program to react to such a
Rat?
When you represent a Rats as a string, there is a good chance you will lose precision:
QUESTION
I am trying to learn both state management & dependancy injection with this demo project. I'm trying to demo injecting some methods all over the place like I may need to in my program. I'm using GetX because I like being able to do this without context in non-widget classes.
So my problem here is the last method, summationReturns(), in the last class below. Attempts to take methods with return statements and add them together. I call this in two places. In the floating button, this works fine but in my text widget I get a dirty state error.
Why is this not working when everything else works? And I assume this will be a corollary from the last question, what is a dirty state? Seems like two questions but I would imagine that they are one in the same.
...ANSWER
Answered 2021-Apr-22 at 06:15Calling update while build is ongoing is an example of dirty scenario. To fix your issue, do not call update inside the GetBuilder.

QUESTION
I'm completely new to SalesForce and have inherited a report that's not working. Please excuse any incorrect terminology, since I'm learning about all this as I go. The report has three prompts: states, years, and members. All dropdowns are supposed to populate with data returned from functions in an APEX class. State, which populates from a picklist, and years, which is populated with a loop, work fine. Members, which populates from a SQL query, returns nothing. If I run the report without any prompts selected (which should return an unfiltered list of results from a SQL query), it also returns nothing. Both of the SQL queries return data when I execute them directly in the query editor in the developer console, but they return nothing when called from the APEX functions.
Here's the initialization code from the Lightning controller:

Right, it's a public page, it's called "Salesforce Sites". It's exposed to whole world without having to log in. These have special security in place because most of the time you don't want to expose data like that. At best you'd display contact us form, maybe some documents to download, product catalog... It's all very locked down, default is to ban everything and then admin decides what's allowed. It's bit unusual to have a Visualforce page + Aura component but ok, it happens.
You (and any other internal user) can see the results if you'd access this page from within salesforce. Something like https://mydomain.my.salesforce.com/apex/SearchBinReceiptsByYear and for you the page will work fine, "just" not outside of salesforce.
When exposed like that on the web - there's no logged in user. There's special "[Site Name] Guest User", you can see them if you search "Sites" in Setup. It has a special profile, also with [Site Name] in it. And nasty thing is - it doesn't show on the list of Users or Profiles.
Your code broke when Salesforce (auto)activated a critical update. Probably this one: https://releasenotes.docs.salesforce.com/en-us/spring20/release-notes/rn_networks_secure_perms_guests.htm There are some good resources on the net if you Google "Secure Object Permissions for Guest Users", for example https://katiekodes.com/salesforce-spring-20-guest-user/
Ask your system administrator colleague or read up a bit about sharing rules.
You'll have to go to Setup -> Sharing Rules. There's a checkbox that caused your stuff to break and you can't untick it.
Scroll down to your TRC Account object and hit "New". You'll need to create something like this, but with your criteria (TRC Member equals true)
Save, wait a bit (it might take a while to recalculate the sharing, you'll get an email) and try the page.
If it still doesn't work you'll have to check the Guest user's profile, it might need permissions to Read TRC Accounts and their Name field.
If it's Salesforce Sites - try this to find it: https://help.salesforce.com/articleView?id=000334554&type=1&mode=1
If it's a Customer Portal, Community, Digital Experience (they renamed the product few times) - try with https://help.salesforce.com/articleView?id=sf.rss_config_guest_user_profile.htm&type=5
Original answer
It looks like it's running OK because accounts (members?) are fetched first and in that fetch's callback (what to do when data comes back from server) you have helper.getLocationState, helper.getYear. And you wrote that these populate OK. It's not the best performance code but it should get the job done.
In no specific order...
Does the whole thing work OK for sysadmins? Or is it broken for everybody? If it works for sysadmins it might be something to do with sharing, your sysadmin should know (Setup -> Sharing settings is where you control who can see what. Maybe "mortals" are not allowed to see any data? Typically sysadmins bypass it. As a quick & dirty test you can modify the class definition to global without sharing class DataTableLocations but it's a really ugly hack.
What happens if you open DeveloperConsole (upper right corner) while running this component, do you see any errors in the logs? What happens if in the console you go Debug -> Open ExecuteAnonymous and run this piece of code:
QUESTION
In this blog, Tech Crunch says,
Google launches Jetpack Compose, an open-source, Kotlin-based UI development toolkit
This means JetPack Compose is an open-source framework (obviously). Then... where's the source code for Jetpack Compose? And how can someone contribute to it?
I searched for the same on the internet but found nothing. Any leads would be very helpful. Thanks in advance.
...ANSWER
Answered 2021-May-24 at 13:19You can check out this contributing guide and here's the compose source code: https://github.com/androidx/androidx/tree/androidx-main/compose. Note that not all libraries from Android are open for outside contribution AFAIK, but you can definitely contribute to the Compose compiler.
Yigit recently answered a related question on I/O 21. As a summary: they plan on opening up libraries so that everyone can contribute, but it has an effect on their regular development processes.

QUESTION
The Google sheet at the URL below contains two worksheets, Sheet1, Sheet2.
Google sheet: https://docs.google.com/spreadsheets/d/1pgdF1hoid8m1Zj3KburwjZRGkydLh1Sum4DshUMaIeo/edit#gid=0
When I use the Query URL #1 below, it successfully returns a JSON file with the correct result for the query: SELECT B where A contains "nut" (the result being the string "crunch")
Please note that the worksheet "sheet2" contains a different table as you can see at: https://docs.google.com/spreadsheets/d/1pgdF1hoid8m1Zj3KburwjZRGkydLh1Sum4DshUMaIeo/edit#gid=1652705509
If I try to query that worksheet with the Query URL #2 shown below, it does not work (it should return a json file with the result "raccoon"). Instead of returning that json file, it only displays that worksheet. What am I doing wrong?
Thank you.

Answered 2021-May-10 at 16:51The issue is /edit#gid=1652705509/ in the query string.
