Assembler Meetup #22, 2019/11/30
Jenny teach me code translate Not sure our method is unify or not Trying to make the grammar file shorter and uniform
Verilog syntax conflict
I guess syntax conflict or not is depend on how fpga vendor implement their verilog compile, nothing about the verilog language specification
Hacking Lattice toolchain lesson 1

Simplest guide to config tomcat to use https with lets encrypt’s free cert
Support you have generate a standalone cert using certbot command, and your cert is in /etc/letsencrypt/live/ . If not, follow this https://www.digitalocean.com/community/tutorials/how-to-use-certbot-standalone-mode-to-retrieve-let-s-encrypt-ssl-certificates-on-ubuntu-16-04 Execute openssl command and remember your password Edit tomcat’s conf/server.xml, you just need one connector to serve 8443, no need other conntector Restart your tomcat, it is done. Below is the virtualhost to…

My first notebook that can run SP2019 on-premises
I have to switch back to windows because almost all verilog toolchain only work in windows. And I bought MSI Prestige-15-A10X which has 32GB ram and 1TB nvms ssd, it is only $15300 HKD, super valueable. It is the first notebook which i can run a SharePoint 2019 VM locally.
Netbeans in Mac vs Windows
Netbeans in windows is much more ugly than in Mac, here is my point of view: Font is not align and not beautiful The java swing L&F in mac match with OS, but not the one in windows Toolbar icon style not match with windows
Gitlab CI + Asp.net core
Add auto build and publish using gitlab ci/cd services and deploy to ubuntu.
Assembler Meetup #20, 2019/11/09
Kelvin and Jenny heading to encode b* and c* instructions Desmond keep going to PE format Peter try to add assembler marco. I will think about our own linker format next week.
Assembler Dev #19 2019/11/02
We think the encoding method is stable, asked Jenny to write a wiki, describe how we can encode each instruction https://gitlab.com/quantr/toolchain/Assembler/wikis/Tutorial-of-decoding
Netbeans hangs in Mac since Netbeans 8.2 to now
I have a Netbeans module call “Maven Runner“, it was originally in Ant. When I install it into my local netbeans, it regularly cause the netbeans failed to start. When I was starting Netbeans, the splash came out, then it disappear, but the main screen never show up. Two months ago, i rewrite it into…

Assembler Dev #16 2019/10/12
We finalize our error handling method, in both antlr grammar and java instruction “ADC” fully encoded, but still some combination mis-encoded. That means nasm don’t encode it, but we do https://www.quantr.hk/asmweb , our new testing site is launched
Netbeans module failed to install nb-javac
If you netbeans maven module used this in pom.xml, then you will have this problem

Getting started with RISC-V
https://dantalion.nl/en/getting-started-with-risc-v/ So you have heard of this RISC-V thing typically talked about in the context of microprocessors and to a lesser degree also for desktop processors. RISC-V is an open-source hardware instruction set architecture (ISA). Similarly to how X86 for Intel and AMD is a closed source ISA. Being an open-source ISA any manufacturer can…

Assembler dev meeting #15
2019/09/28 meeting in cityu. We soonly clear up all combination of ADC instruction. Updated the testing web https://www.quantr.hk/asmweb
Mac inconsistence free disk space between “System Information” and “Disk Utility”
This command can fix: sudo tmutil thinLocalSnapshots / 10000000000 4
Assembler dev meeting #14
2019/09/21, as usual, heading to our first milestone. Enhanced the full test output, added two filters. Filter out by instruction or by error. http://www.quantr.hk/wp-content/plugins/NasmWeb/public//viewOutput.php?path=/home/gitlab-runner/output/output_300588484.html Jenny and Kelvin is clearing the ADC instruction Desmond is extending https://gitlab.com/quantr/toolchain/quantr-executable-library to support Windows PE format
Serious hanging problem in Microsoft Flow
I got a list on SharePoint Online, which is a typical list with some single-line col and one lookup field. I create a flow to get all item from it (no filtering), then use “Apply to each” to loop through all items. For testing, i got two identical loops. After i run it, one successful…

Assembler dev meeting #13
2019/09/14, we met in cityu again. I finished IMM in other project https://gitlab.com/quantr/toolchain/antlr-calculator-library . So Assembler’s parser will eat up the whole numeric string and then pass it to antlr-calculator-library, if it contains a maths expression, it return the final answer which is a number. I created another library to produce ELF output. Jenny and…

ELF Specification 1.2 is only for 32 bits
I am writing a java library to manipulate 64 bits ELF, so i read ELF specification 1.2 , but one big mistake i took is : this specification is only for 32 bits, and the 64 bits one introduce new data types. So I was trying to guess out what data types it is using…

Assembler dev meeting #11
sync-ed up Jenny coding skill to all of us. Jenny now clearing all useless code, rename variables to a more meaningful name. Our next job is to encode all instructions together, and for me, create an ELF library to output ELF format object code. Here is our tuned assembler grammar https://gitlab.com/quantr/toolchain/Assembler/blob/master/src/main/java/hk/quantr/assembler/antlr/AssemblerParser.g4
Assembler dev meeting #10
As usual, #10 meeting was hold in CityU. We getting more familiar with Intel basic instruction set translating. Here is the actions list for next week: Zero padding, cut of pad “0” Jenny consolidate your code into well format, let us understand and give us tutorial next sat morning Desmond: nasm in linux example, able…

Generic E-Form system design
Lots of customers has implemented e-form using different technologies such as Nintex, SPFX, Microsoft Flow. We are going to design a generic E-Form system for them, providing a centralize mechanism for administrators to add/remove eform, user management, log management and etc…
