i have following problem: i have windows 2003 ras vpn server configured single nic (let's call lan1) behind firewall (lets call it's public address wan1). pptp & l2tp ports forwarded server. when client (windows or linux) in remote network behind firewall (lan2) tries connect pptp vpn on wan1 goes fine. when second client in same lan2 tries connect same vpn on same wan1 error 629. it's independant of machine gets first connection. apparently problem independant of router/firewall hardware of lan2 (we have tested @ least 5 different types of remote small router/firewalls - linksys, huawey, d-link, etc.) the firewall wan1 listens 2 internet connections. problem independant of external address clients pointing (even if 2 different workstations point different ip addresses attempt stablish vpn). inside lan1, there no such limitation , multiple workstations connect fine. theres no limitation different remote lans. is limitation of pptp protocol? thanx...

i have meta table , creating stored procedures using t-sql string concatenation. declare @sql varchar(max) = 'select '; select @sql += ... meta -- select clause select @sql += ... meta -- clause .... it's hard maintain when stored procedures complex. is better to declare @sql xml = (select ... meta xml, auto); -- apply xslt transformation how xslt in sql server 2008? clr function way? other solution these kind of meta programming in t-sql? i think xquery should enough purpose.

how transform dictionary input real dictionary can process? when execute external command, get. {'aaa': {'test_a': 0.11666666666667, 'test_b': 1, 'total_c': 0.11666666666667}, 'bbb': {'test_a': 32.883333333332999, 'test_b': 1, 'total_c': 0.11666666666667}, 'ccc': {'test_a': 11, 'test_b': 31, 'test'_c': 33}} so, can see, above dictionary-format already. thinking of doing like. #!/usr/bin/python import command result = commands.getoutput('<execute_external_command') so 'result' becomes dictionary , can process dictionary. from simplejson import loads result='{"name":"anton"}' dictionary=loads(result) print dictionary result="{'name':'anton'}" dictionary=loads(result.replace("'",'"')) print dictionary

my question: 1)in book modern operating system , says threads , processes can in kernel mode or user mode, not what's difference between them . 2)why switch kernel-mode threads , process costs more switch user-mode threads , process? 3) now, learning linux,i want know how create threads , processes in kernel mode , user mode respectively in linux system? 4)in book modern operating system , says possible process in user- mode, threads created in user-mode process can in kernel mode. how possible? user-mode threads scheduled in user mode in process, , process thing handled kernel scheduler. that means process gets amount of grunt cpu , have share amongst user mode threads. simple case, have 2 processes, 1 single thread , 1 hundred threads. with simplistic kernel scheduling policy, thread in single-thread process gets 50% of cpu , each thread in hundred-thread process gets 0.5% each. with kernel mode threads, kernel manages threads , schedules them indep...

i'm doing basic operation start given directory, , traverse filesystem until hit root. on linux/mac, root / , on windows can c:\ or drive letter of course. question whether or not there way node.js identify root directory of filesystem is. currently, i'm resorting checking last directory against path.normalize(dir + "/../") see if stops changing. there process property/method out there? maybe module? would not work? var path = require("path"); var os = require("os"); var root = (os.platform == "win32") ? process.cwd().split(path.sep)[0] : "/"

i had serious bug, forgot return value in function. problem though nothing returned worked fine under linux/windows , crashed under mac. discovered bug when turned on compiler warnings. so here simple example: #include <iostream> class a{ public: a(int p1, int p2, int p3): v1(p1), v2(p2), v3(p3) { } int v1; int v2; int v3; }; a* geta(){ a* p = new a(1,2,3); // return p; } int main(){ a* = geta(); std::cerr << "a: v1=" << a->v1 << " v2=" << a->v2 << " v3=" << a->v3 << std::endl; return 0; } my question how can work under linux/windows without crashing? how returning of values done on lower level? on intel architecture, simple values (integers , pointers) returned in eax register. register (among others) used temporary storage when moving values in memory , operand during calculations. whatever value left in register treated return v...

i have few links on page refers content divs on same page. i'm trying create simple horizontal sliding effect sliding effect show content. example, box1 content should visible, , when clicked on link2, box2 content shold slide in. <a href="#box1">link 1</a> <a href="#box2">link 2</a> <a href="#box3">link 3</a> <div class="content"> <div id="box1">..</div> <div id="box2">..</div> <div id="box3">..</div> </div> please have @ jsfiddle here: http://jsfiddle.net/g9evf/ maybe this? http://jsfiddle.net/3vrh9/4/ making use of plugin http://demos.flesler.com/jquery/scrollto/ plugin source: http://demos.flesler.com/jquery/scrollto/js/jquery.scrollto-min.js

i wanted create outline constraint alter key(not null + unique), think not null constraint can't placed outline, therefore, think have options: outline constraint: check(attr not null) in-line constraint not null + outline constraint unique(attr) is there difference between set in-line constraint not null column , add constraint check (column not null) ? thanks in advance defining column not null preferred approach. indicate in dba_tab_cols , all_tab_cols , , user_tab_cols data dictionary view, example, column not nullable . conventional approach future developers more expect not null constraints defined on columns cannot null . just define unique constraints along not null constraints rather creating primary key constraints, define check constraints rather not null constraints. both approaches work in same way functional standpoint. data dictionary views display approaches differently tools rely on data dictionary may behave differently. , co...

i'm trying make post request server along massive string of data placed database. noticed cut off @ point (about 440k of data in 1 variable). i'm wondering how data can rails hold in parameter pass server? thanks. there no limit imposed rails on size of posted data (or data passed in url) other intermediaries may have have limits however, example nginx has client_max_body_size . check database settings: if data longer maximum length of corresponding column databases silently truncate (others raise error). i'd start checking in controller parameters have expected length.
