Question: Starting an undesirable but well paid and stable job right out of high school or going to college?

College wasn’t really an option for me following graduation where I originally planned to take a gap year and save money to pay my tuition for community college

Somehow some way I managed to absolutely kill it during my interview for a union apprenticeship that I thought I had no chance getting bc I was just some teenage kid with no experience in construction

I was accepted into my local plumbers union shortly after high school and couldn’t have been any more grateful. I even got emotional when I received my letter bc I imagined myself wasting a year of my time saving for tuition knowing my hard earned money would go towards an associates that’s basically worthless. I finally had direction and a career path to follow

The majority of the congratulations I received were fake and followed by warnings of layoffs and health problems. I understand that there’s an assumption of risk factor and i’m well aware of the cons of construction jobs

But my whole point that I try to get across that millennial likes myself and their white collar parents don’t understand is that there’s a difference between an 18 year old and a 30 year old when they first get into the Union.

Realistically a 30 year old 1st year apprentice has 30 years ahead of him before retirement. As for myself I can put 40 years in and STILL retire younger than the 30 year old.

Is it worth it to put in my 30 years and retire at 48? Or will 30 years of service still break me down before i’m in my 50’s

Error when starting apache – apr_global_mutex_lockfile

Good morning,

I am trying to start up Apache HTTPD 2.4.23 on my Centos 5.11 (Linux version 2.6.18-371.6.1.el5 (mockbuild@builder10.centos.org) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-54)) server. I manually configured it with the following options:

  • With apr 1.5.2
  • With apr-utils 1.5.4
  • With pcre 8.37

My HTTPD.conf file looks like this:

{#
# This is the main Apache HTTP server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See  for detailed information.
# In particular, see
# 
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path.  If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "logs/access_log"
# with ServerRoot set to "/usr/local/apache2" will be interpreted by the
# server as "/usr/local/apache2/logs/access_log", whereas "/logs/access_log"
# will be interpreted as '/logs/access_log'.

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path.  If you point
# ServerRoot at a non-local disk, be sure to specify a local disk on the
# Mutex directive, if file-based mutexes are used.  If you wish to share the
# same ServerRoot for multiple httpd daemons, you will need to change at
# least PidFile.
#
ServerRoot "/opt/apache"

#
# Mutex: Allows you to set the mutex mechanism and mutex file directory
# for individual mutexes, or change the global defaults
#
# Uncomment and change the directory if mutexes are file-based and the default
# mutex file directory is not on a local disk or is not appropriate for some
# other reason.
#
# Mutex default:logs

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the 
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 12.34.56.78:80
Listen 8080

Include conf/mod_jk.conf
Include conf/VirtualHost.conf
}

Now, the problem I am having. I start apache by going to the bin folder and running./apachectl start. However, the first thing that happens is, I get an error:

[root@cs-uktest2 bin]# ./apachectl start
httpd: Syntax error on line 116 of /opt/apache/conf/httpd.conf: Cannot load modules/mod_proxy.so into server: /opt/apache/modules/mod_proxy.so: undefined symbol: apr_global_mutex_lockfile

So, I comment out the mod_proxy module in HTTPD.conf, and all it does is tell me the same error for the next module, until I get to mod_rewrite.so. Now, I have this switched on in VirtualHost.conf, which looks like this:

[root@cs-uktest2 conf]# cat VirtualHost.conf

Servername 172.17.100.42
ServerAlias 172.17.100.42
DocumentRoot "/opt/apache/htdocs"
ErrorLog logs/172.17.100.42-error.log
CustomLog logs/172.17.100.42.log common
RewriteEngine On
JkMount /jkstatus/ stat
JkMount /manager* lb


so I cant very well disable it. When I do disable it, I just get an exception when it tries to load VirtualHost.

Oh, for clarity, I am using apache as a load balancer for two other application servers. Therefore I have also installed tomcat connectors, but I configured this post-installation with apxs.

If anyone has any idea why I am getting this undefined symbol: apr_global_mutex_lockfile issue then I would be very grateful to hear from you! I have done substantial googling and plenty of people talking about problems loading Mod_ssl.so and getting this error, but I am not using mod_ssl.so!

Its worth confirming that mod_proxy.so DOES exist in my modules directory, and mod_proxy.h is in the ‘include’ folder too. Perhaps that is the problem?

I have reconfigured apr, apr-utils, pcre and apache several times to see if it solves it. It doesnt.

Thanks in advance

Who is the author of this contradictory poem starting “The night was dark and stormy”?

Does anyone know the name of or the author of the poem below? My grandfather used to say it all of the time and I would like to read it at his funeral. It’s very silly and goes something like this:

The night was dark and stormy,
The sun was shining bright,
The victims lips were tightly sealed,
She screamed with all her might,
Oh kill me friend but spare my life,
The villain shot her dead,
A gay young girl skipped down the aisle,
Grey hairs on her bald head,
She recognized the dying girl,
“Oh who is this?”, cried she,
The headless corpse raised up its head and said, “It’s only me.”

Starting a one-person Ltd options

I have a personal project that’s doing pretty well (over 370k downloads), but with no monetizing solution so far. Before I go in for monetization, I’m trying to browse the different options out there that would allow me to create a brand name/business for this product and a few others so to make them look more authentic.

I eventually came across E-Residency in Estonia, applied for it, got my card then started the process with LeapIn. Everything was going smooth until I learned there’s no guarantee Paypal would approve my business, to then learn that I have no right to enter an email address with my business domain name as my contact information in the Estonian Business Registry, it had to be an @leapin.eu address that I had no access to, this sounded too odd and intrusive to me so I canceled the entire process with LeapIn and got a refund.

I’m rather a technical person (software engineer), I have very shallow knowledge when it comes to taxes, accounting and the legal aspects of starting a business and so I’m seeking advice.

To summarize my situation, I’m currently working as a software engineer in France, I have a resident card which expires in November 2020 (status is renewable), and I’m looking for the best alternatives to start my business while keeping my salarial activity in parallel.

Ideally the business would be location independent, similarly to what the E-residency program in Estonia offers. The goal being to quit my day job and go live somewhere else should the business do well. The key factors for my choice would be driven by:

  • Ease/low fees of company creation (in the form of a one-person Ltd)
  • Lower taxes
  • Unique remote physical address for the company (The program in Estonia uses the same physical address for hundreds/thousands of applicants, which is the major reason I guess for Paypal denying them access to their service)
  • No intrusive policies from the physical address provider/contact person
  • Lower fees for accounting, tax filing, and company creation.

Any hints/recommendations would be appreciated.

Why does starting keepassx only return bus error?

When trying to run KeePassX all I get is:

[1]    21283 bus error  keepassx

I am using an up-to-date

Ubuntu 18.04.1 LTS

Using GDB to start keepassx yields

    Inferior 1 [process 21325] will be killed.

Quit anyway? (y or n) y

I am not very familiar with gdb but it appears keepassx is not crashing in gdb.
This happens both with the version of KeePassX provided by the apt repositories as well as a manually compiled version.
I have tried reinstalling all dependencies using

apt-cache depends keepassx | grep '[ |]Depends: [^<]' | cut -d: -f2 | tr -d ' ' | xargs sudo apt-get --reinstall install -y

to no avail.

I know I don't really have a question, I just don't know what next to do.

I am grateful for any pointers. If this is the wrong Page to ask this question i am happy to delete it and post it in the appropriate place.

Is it OK to cancel a signed employment contract before starting? [closed]

I am a software developer.

A couple of years back I lived in country X and had applied for a position in a company that I was interested of working for. The company was in another country Y and they were willing to take care of the relocation costs. After going through their interview process and signing the contract, but still in my home country, I received an offer of a position with a different company (in country Z) from a headhunter.

My earnings would have been somewhat higher in this offer from the headhunter. But because I had already signed the contract with the first company, I felt it would have been ‘wrong’ to not to honor it. I therefore declined the offer from the headhunter.

Here my only reason for taking the offer from the head hunter would have been an increased take home pay. To me this is not a “real” reason in the same sense as, say, I signed up for a role in some other country but then found that my Mom has ended up in an old folks home and needs me near by.

In this case the first employer had not spent any money on my relocation yet. They had only spent money on FedEx:ing me the contract papers (and I spent money on FedEx:ing those back to them, after signing them).

But afterwards I was wondering on what the ethics would be on this type of thing. Is it unusual or wrong to cancel a start date on a position after signing the contract, esp. if there is no “real” reason?

The reasoning behind this question stemmed partially from the fact that many employment contracts are “at will”. This form of contract is especially common in USA and basically means that neither the employer nor the employee needs to provide a notice period if they want to discontinue the contract. Of course (in my opinion) this is in professional positions probably more often used by the employer, as the employee typically would (should) strive to leave on good terms.

From this perspective the question therefore was that if it is ok to leave the employment immediately after starting, why would it not be ok to leave before starting?

The reasoning also stemmed from the fact that corporations themselves often do not feel an absolute duty to the employee to honor the contract, if for example market conditions change and dictate that it is better for them (from business perspective) to reduce headcount.

So from this second perspective, if employers do not treat these contracts as something that needs to be honored even if it is not financially advantageous, then why should the employee treat them as such?

What are the likely consequences, if any, from cancelling a contract before even starting employment? Do HR departments keep track of this kind of cases just in the event that the person applies for another role in the future?
