Low hemoglobin means that a person's hemoglobin level when measured, is below the lowest limits of normal for their age and sex (see above normal range of values). For example, a 19 year old male would have low hemoglobin if the detected blood value was below 13.6 g/dl.ow hemoglobin means that a person's hemoglobin level when measured, is below the lowest limits of normal for their age and sex (see above normal range of values).

Software Updater. In several Linux operating systems, the Software Updater (previously known as Update Manager) program updates installed software and their associated packages with important software updates for security or with recommended patches.
Updates are typically security fixes of some type or another. Some times they are good fixes and other times they are bad fixes. I prefer not to be bothered by the mess they can create and NEVER update my operating system.
