Anyone knows the requirements for the racks clearance in the server room?  Or recommended clearance off the walls.

I read front should be 36" and rear 24"  Now, what about the sides of the racks?  Contractor is about to install one of my racks with its side flashed to the wall.  I believe it would be uncomfortable to mount equipment with one side right next to the wall.  Screw rails in, cable mgmt, power, etc.
What are the requirements or suggestions.  Thanks in advance.
Hi Experts

This is a follow up on a question asked previously on this forum (https://www.experts-exchange.com/questions/29073016/A-number-of-Services-stop-on-a-RDS-Server-2016.html)

We have a sick RDS 2016.
  • It has ~ 15 users. It is VM on a HyperV 2016.
  • It is a member of an AD.
  • The other VM server is the DC + File & Print
  • Users are using Office 365
  • Each user's Outlook can have between 1 and 5 mailboxes

I have spent several days (probably 40h+) trying to fix it to no avail.

I am considering building a new RDS and migrate all the profiles if I cannot otherwise fix the issues on the RDS.

  1. What would be the recommended way to build the 2nd server to minimise work of transferring profiles (Roaming profile, scripting, RDS farms,...?)
  2. Is there an Expert interested in assisting me with this

Anytime familiar with electric power washers?   I want to switch to electric and not to lose much power.  
Any recommendations?

I'd like to take a list of intervals defined by pairs of numbers, eg

and convert this into a consolidated list counting any overlapping intervals as one, so the above example would give:

See attached drawing that illustrates this.

I want to do this with array/matrix operations, if possible, so I can implement in google sheets without coding.

I noticed a lot of contractors mount electrical receptacles above the racks up in the cable tray.  About 8' high.  Is that a normal practice?
When you bring a heavy UPS on the bottom of the cabinet the cable doesn't reach that high for the 10Amp twist lock plug.  And not very comfortable to run thick UPS cables up 8' to the tray above the rack.  
Is this a new standard practice these days?
Hello, I am currently taking a course on CodeCademy.com on front-end web development so I'm fairly new to programming. Once I complete the course I'd like to begin with some basic projects for work to begin gaining experience. As a rookie, I know I will come across many challenges so I am looking to shorten the learning curve by obtaining guidance and support from a qualified mentor/consultant. Are there any providers out there that offer both free or paid consulting services?
I would need help with project consultation, troubleshooting, code review to ensure adequate standards. Thanks!
In a previous question we're shopping for an ingredient which comes in standard pack sizes of either 100g, 250g or 500g, having prices $0.40, $0.75 and $1.00 respectively.


PackSize = {100; 250; 500}
PackPrice = {0.40; 0.75; 1.00}

QuantityNeeded = {0.... up in steps of GCD(PackSize)... MaxQuantity }

GCD = greatest common divisor, eg GCD({100; 250; 500}) = 50

We only need to define a table with intervals in these steps as in between there won't be any change in the cost. I think this logic is right, please correct me if wrong.

We then define f_mincost(QuantityNeeded ) as the set of packs that meets the QuantityNeeded at minimum cost, eg:

f_mincost(1050) gives 1 x 100g + 2 x 500g at a total cost of $2.40

This problem is solved in the previous question by using dynamic programming to create a lookup table of values:

a) Quantity needed, eg 1050
b) Minimum cost, eg $2.40
c) Pack selection, eg 100, 500, 500

1. What MaxQuantity do we need to tabulate upto before the pattern is repeating
    ie MaxQuantity = some function of Packsize
2. How can we define f_mincost(QuantityNeeded) as a function of this repeating pattern
   eg what is f_mincost(6400) as a function of f_mincost(some value <= MaxQuantity)

This is is probably straightforward but after the previous question my head has been frazzled!

Thanks again
So I walked into this newly built server room and see a water sprinklers hanging right on the top of the racks.

I never seen sprinklers in the server rooms before in my career.  Is it acceptable for the server rooms or absolutely no no?   Wonder other's opinions before I push back hard.  I understand this is not a data center but a server room for 100 users office floor.
Thanks in advance.

Say you're shopping for some ingredients which come in standard pack sizes of either 100g, 250g or 500g, having prices $0.40, $0.75 and $1.00 respectively.

Depending on the exact quantity you need, you can choose to optimise your choice of pack purchases according to price or minimum wastage, or perhaps some combination of the two.

For example if you need 350g, you could buy 1 x 500g pack for $1.00, and waste 150g, or buy 1 x 250g + 1x100g at a cost of $1.15 and have no wastage.

Given the quantity you need, how could you optimise your pack selection mathematically? (a) for minimum cost, and (b) for minimum wastage?

ie some function(quantity needed) gives the pack sizes and quantities to buy, eg:
f_mincost(350) outputs 1 x 500g
f_minwaste(350) outputs 1 x 250g, 1 x 100g

Here is a spreadsheet with some more examples:

Many thanks
I have here what I think is a classical O.R. (operations research) problem. I'm looking to formulate it mathematically and look at the options available to solve it.

We have a list of say 100 recipes.

These recipes combined use 400 ingredients.

The quantity of ingredients required for all the recipes could be defined by a matrix dimension 100 x 400.

We can combine recipes into meal plans, so that the ingredients required for a meal plan is the total of the ingredients required for each recipe in the meal plan.

Each ingredient has an associated cost, that varies depending on the quantity bought.

Say the cost variations can be expressed with no more than 5 cost buckets per ingredient. Eg.

Bucket, Cost / kg
< 1kg, £4.00
1-5kg, £3.50
5-20kg, £3.00
20-100kg, £2.80
> 100kg, £2.50

The ingredient costs can be expressed in two matrices each of dimension 400 x 5:
a) One matrix 400 x 5 giving the buckets for each ingredient
b) Another matrix 400 x 5 giving the unit costs per ingredient and bucket number (1 to 5)

A given meal plan will have a given ingredient requirement, with associated total cost determined via the above matrices.

Suppose we constrain the number of meals in the meal plan to say 4 meals, and these 4 meals must be different recipes. For simplicity (!) we have no other constraints for now.

Our objective is to choose our meal plan (4 meals) such that the total cost is minimised.

1. How do we formulate this problem?
Hi all,
We have an Access VBA application that has grown over the last 10 years into 124k lines of code used by around 400 users. It talks to a main frame and an MS SQL Dbase and is effectively a reporting tool. We have a small young development team on site working with the code base. What I am looking for is a resource that can come in and assess the experience gap and then work with the team to implement a solution. I am thinking mentoring and onsite training/consultation rather than off the shelf training courses as they don't seem to provide any added value. Anyone have suggestions or organizations/people they have used to good effect in the UK?

Gen. Contractor designing the room with wall-mount patch panels.  I never seen/worked with these before.  Normally just on the rack so you can have access both sides.  
Any suggestions/input?  Thanks.
Building a new server room.  What are the opinions to go with CAT6 vs CAT6A.
Heard A its more expensive than regular 6 and more difficult to use in the field due to the jacket thickness.

Please advice.

Working at Home
Working from home is a dream for many people who aren’t happy about getting up early, going to the office, and spending long hours at work. There are lots of benefits of remote work for employees.
I need to change all the users' logon name domain name
so instead of john@companyA.com change to john@companyB.com
In user's properties Account tab.

How can it be done please?
Already have existing AD with windows server 2016 DC.
Trying to add 2nd domain controller and no luck. >> Encountered an error contacting domain ad.name.com
The server is not operational.>>>  >>An Active Directory domain controller for the domain 'ad.name.com' could not be contacted.
I can ping the DC by IP and by name no problem.

Any ideas?
We have MS Volume Licenses.  When trying to activate this box it gives this error.  We do not have an 'activation server'.  This is all we have.  How to solve this issue?
In a meeting some time back, a comment was thrown on the table that over 88% of companies in the US, with 100+ employees, are using social media.  We don't have any social media presences and are now considering it - we did started setting up just accounts for social media that was mention in that meeting (facebook, tweeter, linkedin, youtube, instagram, pinterest).

We understand this is a vast subject, and maybe complicated, but would greatly appreciated any EE that may have some experience in the topic, share their advice  in:

- what to consider prior.
- which social media get into first.
- how many should we set up in.
- doing this less monies possible (as a start).

Thank you in advance.
I've been researching credit cards the past couple of days and there are so many different choices.

I see AMEX is highly recommended, higher yearly fee, along with Chase INK. Card is paid in full each month so interest rates don't matter.

I don't travel much for business. The business is all Web Consulting.

Any suggestions on what you recommend or to stay away from?
