Tierney and Technology

Many companies are rolling out new policies for interacting with artificial intelligence. Some of these new policies and training efforts list assurances that the technology should be viewed as a way to enhance productivity, and not as a means for eliminating current jobs.  Presumably this is an effort to avoid panic. How the affected employee perceives the new direction may stand in stark contrast with the presented policies. A quick glance at the latest bulk of technology Layoffs would give someone pause. Automation isn’t coming around the bend, it is already here. It has been here for ..read more

Working when Traveling can be a pain or it can be less painful. I wouldn’t say it’s a pleasure, but there is often some satisfaction when everything works out well and you can be productive. How you travel determines what you need or think you need to support the tasks and challenges you may face when you are away from your home base or office.  It’s a lot easier for me to take a lot of things with me if I’m using my own vehicle, but even that can present an issue if you’re not always with your vehicle.  What do you leave in your vehicle and what do you take with you from your v ..read more

Man machine mud – it’s all good.

It’s another rainy grey spring day and everything is damp or soaking wet. On the positive side, the grass is green and growing so the amount of mud one might track into their home is not as big a problem as it was only a few weeks ago. If you wish to stomp around outside then a good pair of muck boots would be appropriate for the current conditions. It is boring weather. There are no great torrents of rain, thunder claps or lightning flashes to liven things up to where I would consider the weather conditions slightly more interesting. It’s a dull drippy wet nuisance more than anything else. I ..read more

Heating costs go up, wages don’t, temperatures fall and anything that is available is more expensive. People are lowering the temperature settings in their homes and offices to deal with the increased burden on their finances even as snow storms disrupt daily life. Winter and notably this holiday season may be difficult as the year draws to a close for many. You may be giving or getting a little less in the way of gifts this year than previous seasons. Hopefully you won’t be going deep into debt trying to keep up. Going out to eat has already been scaled way back for most families. Driving les ..read more

The days have grown colder and darker the closer we get to November. The winter forecast calls for cold temperatures and snow. The last few winters have been on the mild side, but this year we may return to what some would call normal winter conditions. With the price of heating increasing and poor economic conditions affecting everyone, it could be a difficult time for many. It’s almost Halloween and there’s enough scary news to send shivers down anyone’s spine. It has been a strange ride these past few years, and it appears that things will continue to get weirder and wilder. A lot of people ..read more
