Job search advice amid COVID-19 pandemic

Reading Time: 5 minutes

We are at unprecedented times, in terms of the pandemic, and the economy aftermath. The IT software dev job market is not impacted as much as some of the hard hit ones such as. travel and leisure, but nobody is also insulated when there is a typhoon. For example, locally here in St. Louis, Enterprise rent a car, the largest car rental company in the US and in the world, has laid off more than 2,000 people, IT division included. I recall about 10 years ago I wrote a post about job search, and I like to update it, amid the time change and this specific pandemic change.

Some obvious things

No onsite interviews, remote or video interview only these days. Zoom is the most popular choice, and for developers there are some white-boarding online software. Realtime white boarding is actually quite challenging, from my personal experience, on both ends. It also depends on the friendliness of the interviewer, some interviewers like to be “above the interviewee”, they give the problem, did not like to talk or give hints, and expect a quick answer right away. On the other hand, there are some other interviewers who are more open and friendly, and sometimes they will throw a dog bone to rescue. As interviewer I always try to be the former, as I personally have been in the receiving end of “bad interviewers”, and don’t like the experience. Once at an onsite interview (long time ago), a guy who maybe quite sharp, made this comment: it sounds like you did much better than the other guys came in earlier, they really don’t know what they were talking about. And at least you put up this and that, blah blah blah… is this a compliment? I guess my English is already good enough to appreciate the underlying tone there. On the other hand, I can always appreciate good / friendly interviewers, once (not in coding or white boarding) during an onsite interview, the interviewer saw my schedule and saw that I was stuck in the little room all day, he offered let’s talk a walk, and talk in the company cafeteria. It was year early / winter 2005 as I recall, in middle of New Jersey.

Websites

Below two the most popular websites now.

Indeed: note Indeed.com is No. 1 in terms of the number of jobs. I found my last job and current job via Indeed.com. This is mind boggling when you think about it. I am not sure whether it exists in 2010. It’a an aggregator website. A bit like Google for information search.

LinkedIn: linkedIn became more meaningful too, I got a job offer in my last round job search and the lead is from LinkedIn. Many companies now post jobs at LinkedIn. Besides the number of jobs, we all know LinkedIn is the top 1 place that recruiters congregate. And as I built profile at LinkedIn, I also received more unsolicited messages or requests from mostly recruiters or website SEO people. Most recently I decided to be more discreet on accepting recruiters request. Most recruiters are young enthusiastic people and I bet they send out things blindly. This brings to another point.

Also, stackoverflow has a job portal, and some of the jobs are looking good too.

Recruiters

I think recruiters are still useful, if we are more discreet and we ask what we want. I have some recruiters friends from both ends as well: job search, or candidate technical screen. And I keep in touch with them from time to time, as a part of relationship building. Sometimes this could be a simple “hi” when the recruiter is in the hallway or in the office. I do understand, on linkedIn, or via database, sometime some younger recruiters will cold call (the reason I pick up the reason was probably the call from number is an agency I know). And we need to keep things in perspective that’s a part of their job and paycheck too. Also keep in mind we live in a small world especially in the St. Louis IT job market, and sometimes the table can turn quickly. I recall seeing a former coworker at two separate places (and I remember he was not being nice to me 🙂 I don’t have grudges against him, but I just know I probably won’t use him as reference, and vice versa.

Code Test

Not white-boarding or pairing either remote or on spot, but something like hacker rank, or filtered.ai. Those are okay as they are usually not overly difficult, they are fair test in other words. There is some random ones, which is usually some problem a tech lead, an architect came up with. And some of those can be nasty. Once I spent 24 hours on a problem, and could not solve it. I solved it a day later. Also noted the behavior type questions on filtered.ai or company recruiting website. Those are easy ones to score points, so don’t waste the opportunities. Usually they let you re-do if the first recording does not look good. The coding test, if done properly, you can run the unit test on the editor and you know it’s failed or passed.

(Update 05-19-2020) There are a lot of online code playground or white boarding tools for code testing on the spot. Those are mostly collaboration tools, with some syntax highlighting. But it’s usually not as powerful as the hacker rank or filterer.ai as the latter ones usually have the build-tests, so basically you will know your code is good enough or not by passing those tests (tests are usually hidden though). Tools such as code labstack are still pretty useful. One thing I am not sure is how they manage the sessions. From interviewer (hiring side) point of view, it maybe helpful to give a heads up if a quick code test is expected so that the candidate is aware. I have seen candidate just bail out without even trying. I have been on the receiving end of this kind of test as well. Again the interviewers friendliness (more precisely helpfulness, do they just want to see the candidate fail, or they want to be as human as possible) varies. (sample java code question here). Also JavaScript code playground such as codepen.io (more links for codepen clock 1 mine and clock 2 Dan Abramov) and jsbin.com .

My javascript code samples.

Last but not least, problem solving questions. One example: Suppose we have 8 balls: one is heavier than the other 7, the other 7 are identical. Now we have one balance (or scale), and we can put balls on two sides to weigh and compare. Use as few attempts as possible, to find the heavy ball? A follow up question is, if we have 2 or 3 attempts, how many balls can we handle (again one heavy ball with many identical lighter balls). 

About me. Also you may read about my other post on related topic.

Also, please note this guide on job search. I haven’t read the whole thing but it appears good. Much longer than this blog. Last but not least, this post is a good read too (Helen Anderson @helenanders26).

GCP Cloud SQL hibernate issue

Reading Time: < 1 minute

It complains the table does not exist when in the data.sql we were trying to insert some data. Turns out the table did exist but the default table name was lower case, while we were using Upper case both in the data.sql and the java hibernate entity. The fix is to add one line in the application.properties file. Note this is a spring boot app. Also note the data.sql was used to load initial data in spring boot.

spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

I found out about it as I first work around the issue by doing something like shown in this article. But I was thinking this was not right. I was able to find out once I connect to the cloud sql db via proxy. Also refer to this stackoverflow discussion. 

DROP TABLE IF EXISTS employee;

CREATE TABLE employee (
  empId VARCHAR(10) NOT NULL,
  empName VARCHAR(100) NOT NULL
);

Also Spring Data

Spring data REST reference: this is by default will be shown in the root of the website.

the key seems to be adding this in pom:

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-rest</artifactId> </dependency>

Last but not least, to disable the end points or to show the available ends points for spring boot app, we can use actuator.

management.endpoints.web.exposure.include=mappings

We can show the end points at:

Spring, Spring Boot, React and OAuth

Reading Time: 4 minutesBaeldung : A Comparison Between Spring and Spring Boot

Tutorials from Okta
Working in progress

Identity, Claims, Tokens – An OpenID Connect Primer, Part 1 of 3 (Micah Silverman, below 2 and 3, are also by Micah)

OIDC in Action – An OpenID Connect Primer, Part 2 of 3

What’s in a Token? – An OpenID Connect Primer, Part 3 of 3

Secure Service-to-Service Spring Microservices with HTTPS and OAuth 2.0 (Matt Raible) : some errors due to java certs

Completed

Build a Basic App with Spring Boot and JPA using PostgreSQL (Andrew Hughes): this example uses Springboot, postgres and Okta single page web app, groups / users and authorization server (default). It goes through a basic springboot app using postgres, before adding the auth (token) from okta. It’s a very good example of how we secure an end point as well as authenticating via user group (admin vs normal / everyday user). The OIDC debugger tool created by former Okta engineer Nate Barbettini is very slick too.

Secure a Spring Boot REST API with JSON Web Token Plus references to Angular integration (Nouhoun Y. Diarra) : a small typo: the health check URL should be http://localhost:8080/actuator/healthTutorial:

Develop Apps with Secure WebSockets in Java (Jimena Garbarino): 

Secure Reactive Microservices with Spring Cloud Gateway (Matt Raible) link to my github

A Quick Guide to Spring Boot Login Options (Andrew Hughes)

Easy Single Sign-On with Spring Boot and OAuth 2.0 (Micah Silverman): note the need for JDK 11 (I used Amazon JDK 11), and please remove the double quotes around claim name and re-type (copy paste does not work well from blog post to okta dev console)

Build Spring Microservices and Dockerize Them for Production by Raphael do Vale. As I was finishing up the regular part (the exercise before docker), the service discovery reminded me of Hashicorp Consul tutorial I followed along a while ago. Note this tutorial used Netflix Eureka which is a bit more cool than pure command lines from Consul / Vagrant 🙂 Note this for Docker (quote the tutorial): You must store the file school-ui.properties in the same folder specified on the volume mapping (in the example above, the relative folder ./config-data). This is also my first complete tutorial on Docker container running java web apps (on my local MacBook and Windows 10). In the past I followed tutorial that runs Chef as well as Tomcat / Jenkins on docker (GCP).

Build a Secure Notes Application with Kotlin, TypeScript, and Okta by Matt Raible. Note the last part also talked about how to push code to Pivotal Cloud Foundry and deploy the apps there. This is interesting as I have done the PCF 15 minutes tutorial in the past (and recently).

Bootiful Development with Spring Boot and React (Matt Raible at Okta): I followed this tutorial until the point that I get the basic beer list (in other words, I made both the basics of Spring Boot and React work). This is my very first venture into React, and I had to install “yarn” as well using brew install. In the process I had to upgrade the Xcode via command line.

Also: Use React and Spring Boot to Build a Simple CRUD App (Matt Raible at Okta): I made small mistake when initiating the project with Spring website: I copied / pasted the dependency frameworks, which seems does not have any effect when the pom.xml was created. So I added the dependencies manually.

			org.springframework.boot
			spring-boot-starter-web
		
		
			org.projectlombok
			lombok
			provided
		
		
			com.h2database
			h2
			runtime
		

Also in my Eclipse, I need to install Lombok manually by following instruction here. Note Matt did mentioned the IDE cannot recognize some of the Lombok things if there is no plugin. In the past I used to install Plugin via the menu inside Eclipse. I noticed “Whitelabel error” when I was hitting the end points: http://localhost:8080/api/groups/ (this is working as expected actually, before I add any JUG meeting to the list, as I don’t have access to the default list).

Last but not least: I need to make a small adjustment in GroupEdit.js sample code

'X-XSRF-TOKEN': this.state.csrfToken, (it was just csrfToken and Yarn did not like it)

Docker – second take

Reading Time: 3 minutes(Update 08-26-2020) Technically 3rd take. I was following along with the Google Cloud Storage ClamAV tutorial, and had an issue of not being able to connect to port 3310 on GCP. (Update 08-29-2020) It was solved. Some tips:

====

1) There were some typos: such as the directory related to the git project, as well as environment variable for the bucket (in couple places);

2) Need to run the below command before deploy: Assign bucket permissions before “gcloud app deploy” (as in section Create the malware-scanner service: step 5)

3) https://github.com/GoogleCloudPlatform/docker-clamav-malware-scanner/issues/1 (move the local variable out of the large bracket {})

4) https://github.com/GoogleCloudPlatform/docker-clamav-malware-scanner/pull/4 (the solution is to increase the memory footprint in the app.yaml file)

====

Last but not least, one does not have to delete the project, the quick way to save the money is just to turn off the app via app engine => settings => disable application.

I also looked around and found another ClamAV tutorial using Java. The second one worked for me locally. I was also able to put an image to the docker hub (using the code from the spring boot docker tutorial). I was able to push the docker image to pcf too. The one thing remaining is I had a 502 gateway issue when I test the end point (local was working fine; postman tip here). Actually later I was be able to make the GCP example (the node js example) work locally too. Now the next step is to make them work in a PCF or a GCP cloud environment (not just local).

(Update 02-04-2019) What Is Container Orchestration? (by Isaac Eldridge at New Relic).

I also followed along the Exploring Docker [1] – Getting Started by Traversy Media. I did make the node.js and MongoDB work on my local MacBook, but I could not make them working on my DigitalOcean droplet due to mismatch of Docker versions of “Docker Compose”, the root cause was the Ubuntu on my Droplet was a a bit old (14.0.4). I need to upgrade it to make the versions compatible.

(Update 02-13-2018) So I found out today I have AWS bill of

$2.62 (mostly due to EC2 instances) today. This is due to the fact that I did fire up the VM as well as the docker swarm instances (total 9? maybe due to I ran the deploy script multiple times?) Anyway I fired up the instance last night, this evening I looked at the “instances” and looked at the bill, I know what happened. I still did not make the connection from outside to ec2 working though. For the time being, I “terminated” the docker swarm, and stopped AWS VM.

(Update 02-12-2018) I am also following the tutorial at Docker’s official website. I am at step 6 here. And right now, I am stuck in connecting to the AWS vm (was following this Docker guide): step 6 “docker node ls”. I did follow the steps to create docker credentials for AWS.

error during connect: Get https://192.168.99.102:32768/v1.35/nodes: http: server gave HTTP response to HTTPS client

Note this IP address looks like the local default machine: one thing I am not quite sure is how the local connects AWS

(Original 01-31-2018) I installed docker on my mac a while ago and did a simple tutorial. But I never had much chance to play with it until recently. After the training, esp. after I saw use docker container to host Tomcat, and then use Jenkins to startup Tomcat (build and deployment), this whole thing got me interested in docker again. Note I have been learning about docker contain and they seem to be the future deployment model for scalable mobile apps backend: e.g., I know the Robinhood app (the free stock trading app) is container based in the back.

Some resources I used to get started:
1) Youtube docker tutorials (11-18-2018: such as this one Demystify Docker; also noticed this one Docker for GCP. I will see if I can do the training exercise again I mentioned above).
2) Install docker or docker.io on Ubuntu (I have a digitalocean droplet / VM, and its OS is Utuntu);
3) Overcome the error message:
FATA[0000] Get http:///var/run/docker.sock/v1.17/version: dial unix /var/run/docker.sock

The answer is this:

The problem is that your user has not been added to the docker group.

Try:

sudo usermod -a -G docker
If you don’t want to log in/out from your current shell, run:

newgrp docker

Last but not least, install Jenkins on Ubuntu 14.04.

Other error messages (note I am on a Mac)
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running? (when I tried to run some docker command)

It seems the solution is
eval “$(docker-machine env default)”

How to root T-mobile Samsung Galaxy S3 SGH-T999

Reading Time: 2 minutesDid my first root of Android phone. I had two Android phones before, but I never rooted it. This time I had a need for root to add the Chinese language to a Samsung Galaxy S3. The specific model is T-mobile SGH-T999 (shown in the Download or Recovery mode, but the model number on the settings says AT&T model number, which caused some issue for me later down the road).

The main reason for doing this is to add Chinese language support. It looks like by reading the article we can only get it work by rooting. I also looked at another article on the language support that suggested both MoreLocale2 and Language Enabler. Tried MoreLocale2 first but it seems needing root. So I started looked at the root tutorial. Because of the “wrong” model number, initially I thought this is an at&t device (model number at&t samsung galaxy s3 i9300, and here is an tutorial for that). Note the two tutorials are similar (t-mobile root tutorial here), the main difference is the at&t one is more verbose, and it has a link to the mod5 file for the at&t model. The odin program did not work for me initially because I was using the latter mod5 file (mismatch between hardware and mod5).

After that mistake the device was stuck in the Download mode (link to get into the Download mode), and could not reboot. I googled I have to download a Samsung software to get it restored. There were other hiccup too, one being the device cannot connect to my Windows 7 laptop (a bit old HP elite book), even after I install the driver. Had to reboot to make sure they connect. Back to topic, I was able to root after I switched to the mod5 file for t-mobile device. And it worked like a charm. After that I installed the rootCheck and SuperSu app from the Play store.

After the root, reboot I installed the Language Enabler app by Wanam from Google Play store (again refer to the language article above).

Final impression: the Samsung s3 is a relatively old device by today’s standard, but it works as a basic smartphone and adding the Chinese language to it, in my specific case, could potentially save an iPhone purchase (SE starts at about $400 in the states). It just takes some work to get it work, from enabling the developer mode/USB debugging on the device, to the odin software root.

Happy rooting 🙂

Production, production, production

Reading Time: 3 minutesI first learned the “production environment” in 2010, when I worked as contractor for a major railway company. Before that I was mostly in CAD software development and consulting environment the word “production” did not come often. To be precise at Siemens PLM/UGS as developers, we did have access to various production releases and did validation for bug and bug fixes from time to time. Our code goes to release per year or per quarter. But production is not as significant as the maintenance releases, so this is the world of shrink wrap (engineering) software world.

Came to the world of business applications, or web. The first thing I learned is it’s not a good idea for newbies to touch production data. Or for that matter, not good idea for devs to touch that either. Very few people has production access, besides admins (database, web), the few people have access are usually product owner, business analysts, or product support people. And fast forward 5, 6 years, I became one of the latter. This is a privilege. Something I learned over past year:

1) Start from baby steps: e. g., if we want to update 1000 records: start from one or two records, do the update, validate and if everything looks good, do the mass update. This goes th way of divide/conquer too: so for example, if I need to delete 3 or 4 million records in one script (one run), I know it will be a long operation, and I don’t want the operation hang or fail in the middle. So what do I do? I divide the deleting operation into a few, each operation deletes half a million, much more manageable, and I will get the it complete much faster or get feedback much faster.

Contractor or employee ?

Reading Time: 2 minutesA common question for software developer is to be an employee (full time, perm) or be an contractor (W-2, or 1099). Strictly speaking the 1099 is more like a small business, and I have not done it personally. I heard some experienced people did the 1099; I will share if I have that exp. down the road.

I spent most of my career so far being an employee (8 years for Siemens PLM/UGS was the longest); I also spent some time being an contractor (total 3 places, about 28 months). Each option has pros and cons. A few things I learned from my own exp.

1) People have all kinds of expectations for contractors, usually the higher pay, the higher the expectation. For employee, they are a bit more patient.

2) Contract to hire. I found this is usually promised or at least suggested at the beginning, as personally I still prefer to be employee long time. But in two cases, I found they were not the case. All types things happen at client, but in one case looking back I felt the client may never had intention to convert. So this is something to keep in mind as for some people the longevity/conversion is important factor.

Moved domain registrar from bluehost to godaddy

Reading Time: < 1 minuteFollowed this instruction move away from bluehost; and move domain into godaddy. Most instructions are accurate, except one needs to ping pong couple times, started from bluehost first, then at godaddy website, after that I received email from godaddy asking about the transfer, go ahead and use the information in the email to start the official transfer, at last I go to bluehost website and approved the transfer. The interesting part is the entry of name server on my web host (digitalocean) gets updated automatically once I approved the transfer by clicking the link on bluehost. This really surprised me as I was expecting to make changes manually on my own 🙂

You may ask why I bother to transfer? I have actually moved my web hosting from bluehost to digitalocean (shared host to dedicated hosting) a while ago. This is the last step before moving completely away from the bluehost. No ill feeling towards bluehost (although couple years ago it did give me some headache). It’s just the cost between the two are comparable and I like to have more say on the web hosting.

Last but not least, if you have Amex card, check if you have the godaddy $20 off $50 offer. I found it from one of my Amex card, and I used it for domain transfer ($9.99 x 5 years plus a bit tax/fees). So the total will be about $30 after Amex offer. 🙂

2015 Year In Review

Reading Time: 4 minutesIt’s new year again, and obligatory new year resolution time. I think I’m already past that practice: will try to put down iPhone and Macbook more when I’m at home though (I was referring to this comment on 2014 review: Leave the iDevices/mac if I can). I’ve eaten my own words on this one. My younger daughter is at a fun age (17.5 months), being a toddler learning to talk, I’ll play with her more, and of course continue my weekend chauffeur job for my older daughter (skating, dancing/pre-ballet etc).

Job Change
I changed my job again this year. I was not expecting it at the beginning of the year or did any planning. But it worked out so far. Again I hope I can stay at my current place longer 🙂

Personal finance
I stopped contributing to the Exxon mobile DRIP program; started put same money ($100 per month) into IBM DRIP program instead, still using ComputerShares. Was able to save some money in the emergency fund account. But still spent quite some on the following items.

Visited Disneyland;

Got a piano and ready to start piano lesson for Serenity in 2016;

Replaced AC and furnace, the new one (American Standard, same as the Trane brand) works like a charm, also bought two mattresses (one from Mattress Firm local store, another one from US-mattress online store). Long term it’s going to save some money on electricity as this one is more energy efficient.

Workout, exercise, swim
I have been doing swimming for a few years at JCC (both Chesterfield and Creve Coeur locations), as I live near the Creve Coeur location, and I worked near the Chesterfield location last few years. That has been changed as the new baby (July 2014), and new job requirement (June 2015). I have been using UP Band, Fitbit app on iPhone 5s, and in June this year I got Fitbit Charge the same time I changed job. Trying to get 10,000 steps per day per the recommendation. Still try to get some swimming as time permits.

I started walking in the trails at Laumeiers Sculpture park since last Winter: trying to breath some fresh air during lunch break at work. The new place does not have a nature trail like the Sculpture park, but it does have a one mile paved trail. It’s good enough for me. I usually walk at lunch break, when weather permits. Otherwise I would walk the stairs, as not good as outside, but it does the job. One thing I learned over the years is we need to take care of our own health while working, because at the end of the day, we need that to provide for our family, also to enjoy things (this hits home especially whenever I get sick). There is an excellent “Under the Radar” podcast on this ergonomics topic. I recall at my old work place, my coworker had surgery on the capal-tunnel (a common injury from using too much keyboard or mouse). Back pain is also common among office workers (sitting too long). The walk/stretch from time to time is a good way to prevent/reduce that.
